Overview of Common Ocular Diseases

Both optometrists and ophthalmologists treat many common types of ocular disease. However, for the best outcome, it’s important to see an eye doctor regularly. They can identify any issues before they become serious problems.


Fortunately, they can treat all of the diseases mentioned below, and in some cases, you can do certain things to prevent them from developing. Look at the most recent statistics, and you’ll see why good eye health care matters.


Currently, more than 4.2 million people in the U.S. alone over the age of 40 are partially blind or have poor visual acuity. Although a lot of things cause these problems, the ocular diseases listed below are the most common.

 

Macular Degeneration

 

This is commonly referred to as “age-related macular degeneration” because it affects seniors. Not only does it cause blurriness and distortion but left untreated, individuals lose their central vision. In other words, they are unable to see anything through the center portion of the eye.


Two types of this ocular disease exist. First, wet macular degeneration means that abnormal blood vessels that are located behind the retina grow under the macular. Along with leaking blood and fluid, this leads to scarring and, sometimes, permanent damage. Second, dry macular degeneration progresses slowly as part of the natural aging process. Typically, it affects both eyes at some point.

 

Cataracts

 

Roughly 20 million people in the U.S. over the age of 40 have cataracts in either one or both eyes. While they can develop in children, teens, and young adults, cataracts are most often associated with age. With this, a film covers the eye, which, in turn, makes everything appear blurry.


Of all the different kinds of ocular diseases that lead to blindness worldwide, cataracts rank number two. Fortunately, an eye doctor can remove the damaged lens, followed by implanting an artificial one. After recovery, patients see amazingly well.

 

Diabetic Retinopathy

 

If you have diabetes, then you’re at risk of developing this ocular disease. This particular disease causes progressive damage to the retina’s blood vessels. The first stage consists of mild non-proliferative retinopathy and then moderate non-proliferative retinopathy, which blocks some of the vessels.


Then, it moves into stage three or severe non-proliferative retinopathy, which means more blood vessels become blocked. The fourth and final state, proliferative retinopathy, is the most advanced. Although Diabetic Retinopathy does affect just one eye on occasion, it typically involves both eyes.


Start by improving your overall health. Eat balanced meals, keep your blood pressure and cholesterol levels down, and take insulin. In addition, regular exercise, losing weight, and giving up smoking all make a huge difference. From there, a qualified eye doctor can provide you with treatment options to reduce the risk of losing your vision.

 

Glaucoma


Many people think glaucoma is one type of ocular disease. However, it’s a group of diseases that cause damage to the optic nerve. When that happens, people face the risk of losing their sight completely. With glaucoma, the fluid pressure inside the eyes gradually rises.


There are also two categories of glaucoma: open-angle and closed-angle. Not only is open-angle glaucoma chronic, but it also progresses slowly. Often, a person can have this type without knowing it. Unfortunately, they don’t realize there’s an issue until they have a comprehensive eye exam performed.


As for closed-angle glaucoma, it’s usually painful and it comes on suddenly. In addition, an individual can lose their vision much faster with this kind of glaucoma compared to the open-angle kind. Because this happens fast and involves pain, it’s diagnosed much quicker as well.


For these common types of ocular diseases, it’s important to have your vision checked. An eye doctor might simply diagnose you with myopia or hyperopia, followed by prescribing either eyeglasses or contact lenses. If an ocular disease is diagnosed, the optometrist will determine the best treatment plan for optimal eye health and vision.


Sports Vision

Sports vision is a growing niche in the eyecare industry, helping athletes improve their performance skills through the enhancement of visual skills. While regular eye exams are important for checking the health of your eyes and your visual acuity (how clearly you can see a still object at different distances), sports vision testing is recommended for anyone who takes their athletic performance seriously. 
 

Visual skills needed for sports performance

There are several key visual skills that are enhanced through sports vision programs for athletes that aim to achieve their optimal sports performance, these include:


Dynamic visual acuity: this refers to the patient’s ability to see objects clearly while in motion. This is exceptionally important as hand-eye coordination and reflex reactions are essential for success in most sporting activities.


Contrast sensitivity: good contrast sensitivity is needed to determine the difference between an object and its surroundings. Contrast sensitivity is particularly important in situations where there may be low light, fog or glare that could diminish the natural contrast between objects and backgrounds. 


Eye tracking: this refers to the ability to follow a fast-moving object, such as a ball or puck.


Switching eye focus: athletes need to be able to change their focus quickly and accurately from one distance to another. 


Binocular vision skills: also known as eye teaming skills, these skills determine how well your eyes work with one another to produce a single, clear image.


Processing speed: visual processing speed is defined as the amount of time it takes to make a correct judgement about a visual stimulus – for example, how fast a ball is travelling towards them. 


Peripheral awareness: athletes also need to be able to be aware of what is happening at the edges of their vision while also concentrating on a fixed object in front of them.

Sports vision testing can enable your eye doctor to spot any weaknesses that you may have in any of these key visual skills. By identifying them, it is possible for you to undergo treatment to overcome theses issues and meet your specific goals that will ultimately enhance your overall athletic performance. This is known as sports vision training.
 

What’s involved in sports vision training?

Sports vision training refers to a personalized treatment plan that is designed to train the brain to achieve maximum efficiency in the way that it receives, processes, and responds to visual input. Exactly what is involved in your sports vision training will depend on your athletic activity and the visual skills that your eye doctor identifies for improvement after comprehensive sports vision testing. Your treatment program will use a variety of tools, techniques, and exercises. You may also be asked to complete some exercises at home to further enhance your progress. With sports vision training, the ultimiate goal is for athletes to continue to see faster and clearer, giving them a distinct competitive edge.

How Exercise Benefits the Eye

It is common knowledge that exercise plays a critical role in healthy living. Exercise can help improve energy levels, lower blood pressure, aid in weight loss, helps to build muscle and so much more. But one benefit of exercise that is not as well known is the profound impact on your eyesight. 

Based on recent research, eye conditions are usually a direct result of a health issue such as high blood pressure, diabetes, high cholesterol level, etc. While some of these diseases are unavoidable, exercising regularly can definitely help in the prevention of these diseases and in doing so, help keep the eyes healthy. In addition to physical exercise, there are even some eye exercises that can be done to keep your vision healthy. Some examples are focusing on certain points, rolling your eyes in different directions, writing with the eyes, etc.
 

Cataracts and Exercise

According to a study in 2003 and another in 2006, a relationship was discovered between an increase in exercise and a decrease in cataract. It emphasized that there is a greater chance for cataract if there is an absence of physical activity. This implies that taking a light walk or jog around your house or on a field track consistently can contribute to the fight against cataracts.
 

Macular Degeneration and Exercise

According to one study, exercising three times or more on a weekly basis reduces ones’ chances of developing exudative macular degeneration. Exudative macular degeneration occurs when blood vessels grow beneath the retina that are not needed and then leak fluid and blood into the eyes.
 

Glaucoma and Exercise

One major cause in the development of glaucoma is an increase in ocular perfusion pressure. Very light exercises like jogging or walking at least three times weekly helps to reduce the intraocular pressure and improves the flow of blood to the optic nerve and retina.
 

The benefit of eye exercises

  • Protects against dry eyes. Eye exercises help maintain and improve the fluid level in the eyes, thus eliminating the probability of dry eyes because as the eyes are being exercised say by rotation, there is the tendency that fluid is produced.

  • Reduces eye strain and tension. Exercising the eyes daily helps in reducing the strain and tension that has been placed on the muscle. Exercises like rolling the eyes and writing with the eyes help in the contracting and relaxing of the eye muscles. Long hours of study or use of a computer can cause blurry vision, but through exercise, clarity can be achieved by eliminating tension and unnecessary pressure.

  • Make the eye muscles flexible. Exercises like shifting and swinging the muscles of the eyes help promote flexibility in the muscles of the eyes. Just like exercise helps the body muscles, the same thing applies to eye exercises.


Latisse Eyedrops

Many people don’t realize that eyelashes are both functional and attractive. The purpose of eyelashes is to act as a first line of defense for our eyes, preventing airborne dirt, dust and other debris from reaching the delicate tissues of our eyes. You probably don’t know that when your eyes are closed, your eyelashes form a nearly impenetrable barrier against foreign irritants entering the eyes. 

Unfortunately, we aren’t all blessed with naturally thick, luscious lashes. In fact, many people choose to get artificial eyelashes or eyelash extensions to make them appear longer or thicker than they really are. Unfortunately, the challenge of achieving voluminous eyelashes is even greater if you suffer from a condition called hypotrichosis. 

 


Best Foods for Eye Health

Generally, despite knowing how important the role of our eyes is in our day to day functioning, we tend to neglect the day to day care necessary to maintain optimal eye health. Just close your eyes for a minute or you put a non-transparent cloth across your eyes and try to walk around your home or workspace. It is quite difficult, right? That is how indispensable the eyes are.

While it is common knowledge that eye issues are a result of eyestrain or aging, most people are ignorant of the fact that an unbalanced diet, as well as deficiency in certain nutrients, can also facilitate eye issues. This implies that eating healthy means that there are certain nutrients that can help reduce the risk of eye issues. Some of these nutrients include omega-3 fatty acids, lutein, copper, zeaxanthin, zinc, vitamin E, A, C, and beta-carotene. For healthy eyes, there are foods that should be part of your diet daily. They include:

1. Fish- Fish is very rich in omega-3 fatty acids, especially oily fish which have oil inside their body tissue and guts. They are regarded as the major source of omega-3 fatty acids which help in improving the immune system and brain function. More so, it helps in the development of the eye and retina and in keeping the eyes from dryness. It is therefore important to incorporate fish into your diet about 3 times a week. Incorporating fish rich with this needed nutrient such as salmon, tuna, sardines, trout, herring, mackerel, and anchovies about 3 times a week is important in helping to maintain optimal eye health.

2. Eggs- The yolk of an egg contains a combination of the nutrients vitamin A, zeaxanthin, and lutein which help to safeguard the cornea, reducing the chances of suffering from cataracts and macular degeneration and zinc which keeps the retina healthy and aids night vision. Eggs are very complimentary food as it can go with other foods and can also take various forms based on your taste.

3. Carrots- This is the most common food for eye health. It contains beta-carotene and vitamin A which protect the surface of the eyes and help to prevent infections. Vitamin A is a form of protein known as rhodopsin and it is tasked with the responsibility of aiding the eyes in absorbing light. A lack of vitamin A is the reason why there are about 500 thousand blind children every year.  Carrots are easy to get and very affordable. They can serve as snacks or be sliced or diced into salads. 

4. Nuts and Legumes- Legumes and nuts provide a lot of vitamin E and omega-3 fatty acids which guard the eyes against age-related disorders. Brazilian nuts, peanuts, walnuts, lentils, and cashews are perfect examples of legumes and nuts and can be eaten as a form of dessert or taken as snacks based on your choice.

5. Citrus Fruits- Citrus fruits are rich in vitamin C, an essential nutrient for healthy eyes. Vitamin C helps in keeping the blood vessels in the eyes healthy. It also stands against cataracts, and with other nutrients, it helps against macular degeneration. Citrus fruits include oranges, grapefruits, and lemons. The good thing about this food is that they can be consumed on their own or turned into a juice.
 


Diabetic Related Eye Exams

You have almost certainly heard of diabetes, which is one of the most common chronic health conditions in the United States with an estimated 100 million adults currently living with diabetes or pre-diabetes. This metabolic disorder occurs when the body is no longer able to regulate its own blood sugar levels and requires intervention to keep them stable. Most people are aware that diabetes can have serious consequences for our health. However, you may be surprised to learn that it can also influence our vision. This is because patients who are diabetic can go on to develop a complication that is known as diabetic retinopathy. Without prompt treatment, diabetic retinopathy can cause permanent vision loss. It is for this reason that patients who suffer from diabetes are asked to attend regular diabetic-related eye exams. 
 

What is diabetic retinopathy?

For us to be able to see clearly, our eyes need to be healthy and functioning perfectly. The most important component of our eyes are the retina. Found at the very back of the eye, the retina is a patch of light-sensitive cells that have the job of converting the light that passes into the eye into messages that are passed up the optic nerve and into our brain. Our brain then receives them and tells us what we can see and how clearly we can see it. 


The retina relies on a continuous supply of blood, which is delivered using a network of tiny blood vessels. Over time, having continuously high blood vessels can damage these blood vessels causing a leak of blood and other fluids onto the retina. If this happens, scarring may occur which could compromise the quality of your vision. 
 

Am I at risk of diabetic retinopathy?

Technically, anyone who suffers from diabetes, whether it be Type 1 or Type 2, could be at risk of developing diabetic retinopathy. However, the condition is more likely in certain situations. These include if:

  • your blood sugar levels are uncontrolled or poorly controlled

  • you have a long history of diabetes

  • you have high blood pressure (hypertension)

  • you suffer from high cholesterol 

  • you are pregnant


Regular diabetic-related eye exams will enable your eye doctor to monitor your condition and ensure that any signs of diabetic retinopathy are detected and acted upon immediately. 
 

What to expect from diabetic-related eye exams?

The process of a diabetic eye exam is very simple and straightforward. In fact, in most instances, it is included within the other elements of comprehensive eye exam and you may not even realize that you have had a specific test to check for diabetes-related complications. 


Diabetic eye screening is non-invasive. You will be given eyedrops which will blur your vision. These may sting a little when they are administered, but this will pass within just a few moments. Once your vision is blurred, you will be asked to rest your head onto a device and stare down a lens. This leads to a camera which will take images of the backs of your eyes so that your eye doctor can assess the structures, which include the retina, for any abnormalities. You will see a flash when each image is taken, but at no point should you be in any pain. 


In addition to the images of the back of your eye being taken, you will also be given a visual acuity test. This is where you will be asked to read letters off a chart a short distance away, as well as reading from a card held in front of you. 


The information that your eye doctor will obtain from your examination will be able to tell them if you are experiencing any of the signs of diabetic retinopathy. If so, they will discuss the best way to get your condition under control. This could involve a combination of elements, including controlling your diabetes more effectively, taking medications or more invasive treatment to preserve your vision. Your eye doctor will give you more specific information based on your individual circumstances.

Understanding Computer Vision Syndrome

Just a few decades ago, computer vision syndrome (CVS) was not known or understood. However, with an increase in the role of computers in our lives, it has become an increasingly common issue. Researchers believe that 50-90% of people who use computers in their daily lives have experienced CVS to some degree. The amount of time that many people stare into a computer screen is increasing, which puts significant strain on our eyes.

CVS is not considered a single specific problem, but a suite of issues. And with the increased use of school computers, tablets and smartphones, children are also becoming more susceptible to CVS.

This syndrome is similar to many other repetitive motion type conditions such as carpal tunnel syndrome. Problems can start because as we are reading text on a screen, our eyes move in a repetitive motion throughout the day. Once the issue has started, continuing the same behavior can worsen any symptoms. While reading alone uses the same motion, digital screens add flicker, contrast, glare, and light that all put additional strain on our eyes.

Issues may also be accelerated if you should be wearing some type of corrective lens, but don't, and are therefore putting additional strain on your eyes.

Aging can also speed up the progress of these issues. Around the time that people turn 40, the lenses of the eyes begin to harden due to a disease called presbyopia, which affects your ability to see closer objects.
 

What Happens if I have CVS?

There is currently no proof that CVS causes long-term vision impairment or blindness. Continuing to use a computer or any other type of screen can continue to be an annoyance or reduce your ability to see properly. Some of the warning signs of CVS are:

  • Blurred vision

  • Double vision

  • Red or dry eyes

  • Headaches

  • Neck pain

  • Back pain

  • Eye Irritation


If you don’t properly treat CVS when these symptoms occur, you may begin to notice that you suffer from a decrease in overall quality of life or job performance.
 


Vision Therapy

Vision therapy is a treatment plan that is intended to develop and improve a patient’s visual skills and abilities, with the goal of making their day-to-day life easier. You may also hear Vision Therapy referred to as VT. Although most commonly associated with children, whose visual skills are still naturally developing, adults can also benefit from vision therapy.
 

Any patient who does not have the necessary visual skills could find themselves suffering from a range of unpleasant symptoms, including headaches, eye fatigue, stiff neck, and double vision. Fortunately, vision therapy is a simple, painless technique to help patients to enhance their visual skills and overcome any issues that they may have been experiencing.
 

Skills that can be developed and improved through vision therapy

Vision therapy has been shown to be an effective way of developing and improving the following visual skills, all of which are important for day-to-day life. 
 

Tracking: this refers to the ability to follow a moving object smoothly and accurately with both eyes – such as moving traffic or a ball coming towards you.
 

Depth perception: this is the ability to judge relative distances of objects and move accurately in a 3D space – for example, being able to walk down a flight of stairs.
 

Peripheral vision: this refers to the edges of your vision and your ability to assess what’s happening in your peripheral vision while paying attention to something directly in front of you.
 

Acuity at different distances: this is the ability to see clearly enough to identify and understand objects at both near and far distances. 
 

Fixation: enabling patients to quickly and accurately look at, identify and understand stationery objects one after the other, for example, reading word to word. 
 

Binocular vision: the ability for both eyes to work together in perfect synchronization.
 

Shifting focus: patients with this skill can look quickly at different distances without momentary blur. 
 

Visualization: a valuable visual skill that enables patients to form and retain images in their head. 
 

What to expect from a vision therapy appointment?

Vision therapy is generally conducted as an in-office treatment, under the close supervision of your eye doctor. Each vision therapy treatment plan is personalized; tailored to the specific individual needs of each patient. Most patients can expect to schedule hour appointments once or twice a week. You may also be given specific exercises to complete at home, which will support the progress that you are making during your in-office appointments. The components of Vision Therapy Treatment are non-invasive and drug-free, making VT suitable for the vast majority of patients, regardless of their age, health and history. For many people, vision therapy is a safe alternative to conventional eye surgeries.
 

There are various techniques that can be involved in vision therapy. These include, but aren’t limited to:

  • Prisms

  • Patches

  • Occluders

  • Therapeutic lenses

  • Exercises

  • The use of tools designed specifically for use in vision therapy exercises


By attending regular vision therapy appointments, patients can see an improvement in their vision, visual comfort and experience an overall improvement with the ease in which they use their eyes for daily activites.
