As technology continues to advance, so does the field of the optometric industry. The development of innovative tools and techniques has allowed for more accurate and comprehensive examinations. One such technology is Optos, a revolutionary system that utilizes ultra-widefield retinal imaging technology to provide optometrists with a detailed view of the entire retina.
 

How Does Optos Work?

Optos technology is based on the principle of ultra-widefield retinal imaging, which allows for a wider and more detailed view of the retina compared to traditional imaging techniques. The Optos system consists of a specialized camera that captures high-resolution images of the retina using scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT) technologies. SLO provides a wide-field view of the retina, while OCT allows for cross-sectional imaging, providing valuable insights into the various layers of the retina.
 

The Optos camera is designed to capture images through a process called optomap, which captures up to 200 degrees of the retina in a single image. This wide-field view provides optometrists with a comprehensive picture of the retina, enabling them to detect abnormalities that may not be visible with traditional imaging techniques. The optomap image can be instantly viewed and analyzed by your eye doctor, allowing for a more efficient and accurate diagnosis.
 

Common Eye Conditions Detected by Optos

Optos technology has the capability to detect a wide range of eye conditions, including but not limited to, diabetic retinopathy, macular degeneration, glaucoma, and retinal tears or detachments. Diabetic retinopathy is a condition that affects individuals with diabetes, causing damage to the blood vessels in the retina. Optos can capture detailed images of the retina, enabling optometrists to detect any signs of diabetic retinopathy and initiate appropriate treatment.
 

Macular degeneration is another common eye condition that can be detected using Optos. This condition affects the macula, the central part of the retina responsible for sharp, central vision. Optos allows for a comprehensive view of the macula, identifying any changes or abnormalities that may indicate the presence of macular degeneration.
 

Glaucoma, a condition characterized by damage to the optic nerve, can also be detected using Optos. The wide-field view provided by Optos allows for a thorough examination of the optic nerve and the surrounding structures, facilitating early detection and intervention.
 

Finally, Optos technology is particularly effective in detecting retinal tears or detachments. These conditions can lead to sudden vision loss and require immediate medical attention. Optos allows for a comprehensive view of the retina, identifying any signs of retinal tears or detachments and initiate prompt treatment.

Cataracts are a common eye condition that can significantly affect your vision. They occur when the lens of your eye becomes cloudy, causing blurred or distorted vision. This clouding is typically a result of aging, but other factors such as genetics, diabetes, or prolonged exposure to sunlight can also contribute to the development of cataracts.
 

As cataracts progress, you may experience symptoms such as difficulty seeing at night, increased sensitivity to glare, or a decrease in color perception. These changes can make daily activities like reading, driving, or recognizing faces more challenging.
 

Why Cataract Surgery May be Necessary

Cataract surgery is often recommended when cataracts start to interfere with your vision and affect your ability to perform daily tasks. The primary goal of cataract surgery is to remove the cloudy lens and replace it with an artificial intraocular lens (IOL).
 

The decision to undergo cataract surgery is a personal one and should be made after consulting with your optometrist. Factors such as the severity of your cataracts, your overall eye health, and your lifestyle requirements will be taken into consideration when determining if surgery is necessary.
 

What is Cataract Surgery Co-Management?

Cataract surgery co-management refers to the collaborative approach between an ophthalmologist, who performs the surgery, and an optometrist, who provides pre-operative and post-operative care. This partnership ensures that you receive comprehensive eye care throughout the entire process, from the initial consultation to the final follow-up appointments.
 

Your optometrist plays a crucial role in cataract surgery co-management by conducting a thorough pre-operative evaluation to assess your overall eye health and determine the most suitable IOL for your specific needs. They will also provide guidance and education on the surgical procedure, address any concerns you may have, and help you make informed decisions about your eye care.

Every patient is different and so are their eyes. This means that there need to be different types of contact lenses to suit each individual. Some patients have corneal abnormalities which mean that conventional lenses won’t sit comfortably on the surface of their eyes, while others suffer from eye conditions that mean normal contact lenses won’t be comfortable or could irritate their eyes. 

As you may have guessed from the name, specialty contact lenses are unconventional contacts that are designed for patients that regular contacts might not be suitable. Here are some of the main types of speciality contact lenses and who they are recommended for. 
 

Who might be a good patient for specialty contact lenses?

Some of the patients that might benefit from specialty contact lenses include those who:

• have been diagnosed with dry eye syndrome

• have corneal scarring

• have been diagnosed with keratoconus, a condition characterized by the bulging of the cornea

• suffer from strabismus, a condition where the patient has an eye that turns in or out relative to the other

• have suffered an injury to the eye

• suffer from a peripheral corneal thinning disorder

• are intolerant to other types of lenses

Your eye doctor or contact lens provider will be able to tell you if you need specialty contact lenses and if so, which lenses would be best based on your individual requirements. 
 

Corneal refractive therapy, also known as CRT, is a simple, painless treatment for refractive eye errors like myopia and has two core benefits. First, it can be used to help patients see clearly during the day without using glasses or contact lenses, giving them the freedom and flexibility that they need to live life to the fullest. Second, CRT has been shown to help slow the progression of myopia, keeping prescriptions under control and potentially reducing the likelihood of patients developing serious eye health problems associated with high myopia in the future. 

Here’s everything that you need to know about corneal refractive therapy and what it means for you. 

Understanding refractive eye problems

Refractive eye problems like nearsightedness, farsightedness and astigmatism are extremely common, with nearsightedness – also known as myopia – being the most common of all. Patients with myopia can see nearby objects clearly, but those further away become progressively more blurred. Refractive eye errors occur when the shape of the clear dome covering the front part of the eye, called the cornea, impair the light-bending and focusing process in your eyes. This leads to the light ending up in the wrong place inside the eye, and the message that is sent to our brain from our eyes is muddled, causing blurred vision. 
 

What is corneal refractive therapy?

Corneal refractive therapy was initially developed as a treatment to correct and slow the progression of nearsightedness. However, it has also been found to be effective at controlling other refractive errors, including farsightedness, astigmatism and an age-related refractive condition called presbyopia.

CRT is a non-invasive, painless and straightforward method of correcting patient vision so that they don’t need to wear contacts or glasses, and they don’t need laser vision correction surgery to see clearly. CRT uses special contact lenses that are worn overnight and apply light pressure to the cornea in order to reshape it so that light is refracted correctly, and the image sent from the eyes to the brain is clear. The cornea is able to retain this new shape even after the contact lenses are removed the next morning, meaning that you can continue to see clearly for several hours. The more consistently you wear your CRT lenses overnight, the longer your eyes will learn to retain their new shape and eventually, patients can enjoy up to 48 hours of clear vision without using prescription lenses. However, the effects aren’t permanent so if you stop wearing the lenses, your vision will gradually return back to normal over the course of a few days. 

Slowing the progression of myopia with corneal refractive therapy

Another key benefit of CRT is that it can actually help to slow the progression of myopia. Most people who are nearsighted find that their eyesight gets progressively worse as they get older. This deterioration may not be rapid, but it can end in patients requiring high prescriptions. Studies have found that patients who have high myopia are more likely to develop serious eye problems in the future, including glaucoma, macular degeneration, cataracts and a detached retina. Regular use of your corneal refractive therapy lenses could help keep your prescription stable and lower your risk of developing these problems. 

Am I a candidate for corneal refractive therapy?

You may be a candidate for corneal refractive therapy if you:

• Have a myopia prescription within specific parameters

• Have a prescription for hyperopia, presbyopia or astigmatism within specific parameters

• Have stable vision, which means that your prescription hasn’t changed during the last two years

• Are not a suitable candidate for laser vision correction

• Have a job that makes it impractical or unsafe to wear glasses or contact lenses

• Enjoy hobbies that make it impractical or unsafe to wear glasses or contact lenses

• Have healthy eyes and are generally in good health

Visual field testing is an important part of most standard comprehensive eye exams. Also sometimes known as perimetry testing, Visual field testing is a method to measure the entire scope of vision of an individual, including their peripheral/side vision.
 

The importance of visual field testing

Visual field testing is one of the most effective diagnostic treatments in the detection of glaucoma. This is because when patients are affected by glaucoma, it is usually the peripheral vision that is affected by their condition first. However, it can also be used to detect central or peripheral retinal diseases, eyelid conditions such as drooping, optic nerve damage and conditions that affect the visual pathways from the optic nerve to the area of the brain where this information is processed into vision.
 

Visual field testing is also an important part of monitoring for people who are considered to be at risk for vision loss from disease and other problems, including those who have been diagnosed with the following:

• Multiple sclerosis

• Hyperthyroidism

• Pituitary gland disorders

• Central nervous system problems (such as a tumor that may be pressing on the brain)

• Stroke

• Diabetes

• High blood pressure
   

What to expect from visual field testing

There are a variety of methods that can be used to perform visual field testing, including:
 

Static automated perimetry. This is where a machine is used to quantify how well the patient is able to detect flashing lights of varying size and brightness in different areas of their visual field, while they concentrate on a central point. The patient responds by pushing a button when they see the light.

Kinetic perimetry. This involves points of light that are fixed in size and intensity and are presented along the patient’s peripheral vision, before being gradually moved inwards to determine their field of vision. 

Visual field testing is non-invasive, painless and doesn’t require patients to have their eyes dilated. The results, which are usually presented in a series of charts, are digital and sent directly to your eye doctor for interpretation. Depending on the outcome of your results, you may be recommended for further diagnostic testing which could include blood tests. If you have been diagnosed with glaucoma, you will probably be recommended to have several visual field tests each year, which will help your eye doctor to monitor the progression of your condition and recommend treatments to slow it.

If you would like more information about visual field testing, or if you have concerns about your peripheral vision, please don’t hesitate to schedule an appointment with our experienced and knowledgeable eyecare team today.

Ocular aesthetics, which focuses on improving the appearance of the eyes and the surrounding area, has gained significant popularity in recent years. Ocular aesthetics aims to rejuvenate the eyes, making them appear more youthful, vibrant, and refreshed. This can be achieved through advanced technology treatments that are designed to address specific concerns and enhance the overall appearance of the eyes.
 

Common Concerns in Ocular Aesthetics

There are several common concerns that individuals seek to address through ocular aesthetics. These concerns may be a result of natural aging, genetics, or lifestyle factors. One of the most common concerns is the appearance of wrinkles and fine lines around the eyes, commonly known as crow's feet. These lines can make you look older and tired.
 

Another common concern is the presence of dark circles and puffiness under the eyes. This can give the impression of fatigue and detract from the overall attractiveness of the eyes.
 

IPL and How it Works

Intense Pulsed Light (IPL) has emerged as a popular and effective treatment option in ocular aesthetics. IPL works by emitting high-intensity light pulses that target specific chromophores in the skin, such as melanin and blood vessels. This targeted approach allows for precise treatment of various concerns around the eyes.

IPL treatments can effectively address pigmentation irregularities, such as age spots and sun damage, which often contribute to an aged appearance. By targeting these concerns, IPL can help restore a more even skin tone and improve the overall aesthetics of the eyes.

IPL treatments are non-invasive and typically require minimal downtime. The number of sessions needed may vary depending on the specific concerns being addressed. By consulting your optometrist, you can determine the best treatment plan to achieve your desired ocular aesthetics.
 

Radiofrequency (RF) for Ocular Aesthetics

Radiofrequency (RF) treatments have gained significant popularity in ocular aesthetics due to their effectiveness in addressing various concerns around the eyes. RF works by delivering controlled radiofrequency waves into the deeper layers of the skin, stimulating collagen production and tightening the tissues.
 

One of the primary concerns that RF treatments can address is drooping eyelids. As we age, the skin around the eyes can lose elasticity, causing the eyelids to sag. RF treatments can effectively tighten the skin, resulting in a more youthful and lifted appearance. This can help restore the natural contour and symmetry of the eyes, enhancing their overall aesthetics.
 

RF treatments can also target under-eye bags, which can make the eyes appear tired and aged. By stimulating collagen production, RF can improve the overall tone and texture of the skin, reducing the appearance of under-eye bags and giving the eyes a more refreshed and vibrant look.
 

Exploring Low-Level Light Therapy (LLLT)

Low-Level Light Therapy (LLLT) has gained recognition in ocular aesthetics for its ability to promote cellular activity and stimulate collagen production. LLLT utilizes specific wavelengths of light that penetrate the skin, triggering a series of biological responses that can improve the health and appearance of the eyes.
 

LLLT treatments can effectively address concerns such as fine lines, wrinkles, and dark circles around the eyes. By stimulating collagen production, LLLT can help reduce the appearance of these concerns, resulting in a more youthful and vibrant look.
 

In addition to its anti-aging benefits, LLLT can also improve the overall health of the eyes. By promoting cellular activity, LLLT can enhance circulation, reduce inflammation, and support the natural healing process. This can be particularly beneficial for individuals with conditions such as dry eyes or eye fatigue.

Thanks to the advancement of lens technology, glasses lenses are no longer a single, one size fits all solution. There are a variety of different lens types that can be used in glasses, giving patients greater flexibility and control over their vision than ever before.
 

Single Vision Lenses

Also known as monovision lenses, these lenses are designed to correct the wearer’s vision at just one distance, and have a single prescription covering the entire surface of the lens. They are most often recommended for people who are either nearsighted (myopia) or farsighted (hyperopia) and who need glasses for a specific activity, such as driving or reading.
 

Progressive Lenses

Progressive lenses are multifocal lenses that can correct a patient’s vision at different working distances, ranging from far distance to reading distance. However, rather than designating different areas on the lenses for different distances with visible lines separating them, progressive lenses have a gradual change so that the wearer can smoothly transition from one lens power to another.
 

Bifocal and Trifocal Lenses

As you may have guessed from the name, bifocal and trifocal lenses have either two or three lens powers depending on which type you choose. Bifocal lenses support distance vision in the top half of the lens, and near vision in the lower half. Trifocal lenses support distance vision in the top third of the lens, intermediate vision in the middle segment and near vision in the bottom third. Whichever variety you choose, you will see visible lines separating each segment.

Bifocal and trifocal lenses are recommended for patients who are near or farsighted, and those who develop presbyopia, which is the natural hardening of the eye lens, that occurs as we get older. Presbyopia makes it harder for the lens of the eye to adapt to focus at different distances.
 

Multifocal Lenses

Multifocal lenses are the alternative name given to bifocal, trifocal and progressive lenses.
 

Computer Lenses

Computer lenses are prescription lenses that are specifically designed to be worn when doing computer work. This is because they place the optimum lens power for viewing your computer screen exactly where you need it – which is closer than intermediate vision, but further away than reading material is usually held. Wearing computer lenses can significantly reduce the negative effects caused by the high visual demands of computer work, including blurred vision, redness, dry eyes, double vision and dizziness.
 

Transition Lenses

Also known as photochromic lenses, transition lenses are a special type of lens that darken when in the sunlight and lighten when in softer light or the dark. This versatility gives the wearer the convenience of being able to move between different environments without needing to change their glasses. This makes them extremely cost effective and prevent the wearer from needing to take multiple pairs of glasses out with them. Transition lenses also filter out many of the harmful UV rays that are emitted from the sun, helping to keep eyes healthy too. They are ideal for people who spend a lot of time going between inside and outside, or who work outside in varying weather conditions.
 

Blue Light Lenses

Blue light lenses are specially crafted lenses that contain filters that block out much of the artificial blue light that is produced by digital devices like computers, smartphones and tablets. Natural blue light is actually good for balancing our sleep-wake cycle, boosting our mood and enhancing our cognitive abilities so that we can function better day to day. However, too much blue light, especially from artificial sources, can have the opposite effect. Many people who fail to use blue light lenses can go on to develop digital eye strain, which produces symptoms like eye fatigue, dry eyes, blurred vision, headaches and more. Blue light lenses are recommended for anyone who spends a lot of time working on a digital device.
 

Polarized Lenses

Polarized lenses are used to reduce eyestrain and improve the quality of vision in patients on especially sunny days, making them ideal for anyone who spends a lot of time outdoors. They can do this because they have a special filter that blocks some of the light from passing through the lens. Vertical light is allowed to pass through, while horizontal light, such as that which bounces off of water and can be blinding, is blocked. Polarized lenses are most often used in sunglasses since they are worn outdoors, and the wearer also needs to protect their eyes from UV damage.

Post-concussion syndrome (PCS) is a complex condition that can occur after a traumatic brain injury (TBI), such as a concussion. While the initial injury may have healed, the lingering symptoms can significantly impact your daily life, making it challenging to return to your normal routines and activities.

What is Post-Concussion Syndrome?

Post-concussion syndrome is a collection of physical, cognitive, and emotional symptoms that can persist for weeks, months, or even years after a head injury. Unlike the typical recovery from a concussion, which usually resolves within a few days or weeks, PCS can be a prolonged and debilitating experience. The symptoms of PCS can vary widely from person to person, making it a complex and often misunderstood condition.

Causes of Post-Concussion Syndrome

One of the primary causes of post-concussion syndrome is the disruption of the brain’s normal function due to the injury itself. When the brain experiences trauma, it can lead to a variety of biochemical and structural changes, which may cause the ongoing symptoms of PCS. The severity of the concussion does not always correlate with the likelihood of developing PCS; even minor concussions can lead to prolonged post-concussion symptoms in some individuals.

Another contributing factor to PCS may be related to the individual’s psychological response to the injury. Anxiety, stress, and pre-existing mental health conditions can exacerbate the symptoms of PCS and prolong the recovery process. People who have a history of migraines, anxiety disorders, or depression may be more prone to developing post-concussion syndrome.

Recognizing the Symptoms of Post-Concussion Syndrome

The symptoms of post-concussion syndrome can be diverse and can vary in severity from person to person. Some of the most common symptoms include:

• Physical Symptoms: Headaches, dizziness, nausea, sensitivity to light or sound, fatigue, and sleep disturbances.

• Cognitive Symptoms: Difficulty concentrating, memory problems, slower processing speed, and reduced problem-solving abilities.

• Emotional Symptoms: Irritability, mood swings, anxiety, depression, and increased emotional sensitivity.

The presence and severity of these symptoms can fluctuate over time, making it crucial to monitor your condition closely and communicate any changes to your primary care or eye doctor.

Migraines are a debilitating neurological condition that affect millions of people worldwide. One of the most common and disabling symptoms of migraines is light sensitivity, also known as photophobia. This heightened sensitivity to light can be a significant source of discomfort and pain for those suffering from migraines, making it difficult to function during an attack.

Photophobia is a common symptom of migraines, with up to 80% of migraine sufferers experiencing sensitivity to light during an attack. This sensitivity can be triggered by various types of light, including natural sunlight, fluorescent lighting, and even the glow of computer screens or smartphones.

In the realm of eye care, surgical co-management has emerged as a collaborative approach that aims to provide patients with comprehensive and seamless treatment. This concept involves the joint efforts of optometrists and ophthalmologists, each bringing their unique expertise to the table. By working together, these eye care professionals strive to enhance patient outcomes and deliver exceptional care.
 

The Role of Optometrist and Ophthalmologist in Surgical Co-Management

Surgical co-management is built upon the unique skill sets and areas of expertise of optometrists and ophthalmologists. By understanding their respective roles, you can appreciate the synergy that this collaborative approach fosters.

Optometrists are primary eye care professionals who specialize in the examination, diagnosis, and non-surgical treatment of vision disorders. Their responsibilities in surgical co-management include:

• Performing comprehensive eye examinations and evaluations

• Monitoring and managing pre-existing eye conditions

• Providing pre-operative and post-operative care

• Educating patients on surgical procedures and aftercare

• Collaborating with ophthalmologists to ensure continuity of care
   

Ophthalmologists are medical doctors who specialize in the diagnosis, treatment, and surgical management of eye diseases and disorders. Their role in surgical co-management encompasses:

• Evaluating patients' candidacy for surgical interventions

• Performing complex surgical procedures

• Providing specialized medical and surgical care

• Collaborating with optometrists to ensure seamless patient care

• Monitoring and managing post-operative complications

• By combining the expertise of optometrists and ophthalmologists, surgical co-management ensures that patients receive comprehensive and coordinated care throughout their treatment journey.

How Surgical Co-Management Works

Surgical co-management is a well-orchestrated process that involves several key steps. Understanding how it works can help you navigate this collaborative approach with confidence.

• Initial Evaluation: The process typically begins with an optometrist conducting a comprehensive eye examination. During this evaluation, the optometrist assesses the patient's visual needs, identifies any potential issues, and determines if a surgical intervention is necessary.

• Referral and Consultation: If surgery is recommended, the optometrist refers the patient to an ophthalmologist for further evaluation and consultation. This step ensures that the patient receives specialized medical advice and a thorough assessment of their suitability for the proposed surgical procedure.

• Pre-operative Care: The optometrist plays a crucial role in providing pre-operative care, which may include managing any existing eye conditions, ensuring the patient understands the surgical process, and addressing any concerns or questions they may have.

• Surgical Procedure: The ophthalmologist performs the necessary surgical intervention, leveraging their specialized training and expertise in surgical techniques.

• Post-operative Care: After the surgery, the patient's care transitions back to the optometrist, who closely monitors the recovery process and provides post-operative care and management. This may involve follow-up appointments, monitoring for any complications, and ensuring the patient adheres to the prescribed treatment plan.

• Ongoing Collaboration: Throughout the entire process, the optometrist and ophthalmologist maintain open communication and collaborate closely. This ensures that the patient's care is seamless, and any concerns or issues are promptly addressed by the appropriate healthcare professional.
