Ocular Disease

 

We provide diagnosis, treatment and management of diseases which affect the human eye and visual system.  Some examples include:

 

 

Dry Eye Syndrome  occurs when the normal flow of tears over the eyes is interrupted, or the tear film is abnormal.  In many cases, dry eye syndrome is a life long problem.  You can relieve the symptoms, but not cure the original cause.  Artificial tear lubricants or in some cases blocking the tear ducts will concentrate the limited tears that are available.

Keratoconus is a disorder that occurs when the cornea, which is typically rounded, becomes cone-shaped.  The progression is usually slow and can stop at any stage from mild to severe.  This distortion increases as the cornea bulges and thins.  The apex of the cornea often scars, reducing the vision.  Treatment of Keratoconus is most effective with gas permeable contact lenses, designed specifically for the irregular corneal surface.  If contact lens treatment is not successful, surgical corneal transplant may be necessary.

 

 

 

Diabetic Retinopathy  is a condition when a diabetic persons blood sugar gets too high.  High blood sugar levels start a series of events which end in damaged blood vessel walls.  As such, the blood vessels begin to leak fluid or bleed, causing the retina to swell and form deposits know as exudates.  Vision can be lost if these spots are not watched and treated.  Here, at our office, we carefully examine the back of your eyes to follow and manage this and other important eye diseases.

 

 

 

Cataract is a clouding or opacity of the natural internal lens of the eye.  This opacity may be a small spot or may cover the entire lens.  When light enters the eye it is scattered, causing images to appear hazy and blurred.  There are many different types of cataracts.  The one shown here is a cortical cataract.  Here the opacity forms first is the periphery of the lens and develops inward, like spokes of a wheel.  Ultimately, the best  treatment is to remove the cataract lens and replace it with an acrylic man made lens.  This is referred to as cataract surgery.

 

 

 

Macular Degeneration is a condition in which the central part of the back of the eye loses blood circulation.  It is considered a natural aging process.  There is a breakdown of retinal pigment epithelium cells in the macular region.  As the disease progresses, central vision diminishes.  It is believed that this breakdown may be due to a lack of nutrients being supplied to the region. Additional studies have found a genetic link to this disease.  Treatment can range from better nutritional management, sometimes to include a tablet containing the primary minerals and vitamins that are found lacking in many macular degenerated patients.

 

 

 

 Color Blindness and Red Lenses

It's amazing how many people have some sort of color vision deficit. Very few people are truly color blind though, we just call it color blindness as a figure of speech. When you say you are color blind, you are really saying that you see colors differently. Most people termed "color blind" have trouble seeing red or green wavelengths of light. That's why, in certain lighting and color situations, color confusion may occur. Most people with "color blindness" do very well with color naming, under most circumstances. That's also why kids can be color blind for many years before it is discovered.

Yes, it is true that most color blind people inherit this condition from their mothers. The particular gene is sex linked so it rarely shows up in women, but is can if the mom and dad have the right genes. If the dad has the gene it rarely shows up in the kids, but if the mom is color blind, it is likely all the sons will have the same "color blindness."

A few years ago it was noted that color blind people could tell some colors apart if they held a red lens over one eye. This phenomenon doesn't provide true color vision but can allow someone to be sure about colors that don't match, especially pastels. This effect can vary from person to person (it seems to be more effective for green color deficits than for red color deficits), so each person has to individually evaluate the lens. If we discover you have a color vision defect in our exam, we will usually give you a complementary red lens to put on your dresser or in the garage with the paint cans. It can be helpful for you if you work on a computer and have to differentiate colors on the screen. Some have made sunglasses, best with mirror coatings, to allow color differentiation outdoors during the day. We know someone is thinking about one clear lens and one reds lens for driving but this creates a problem with depth perception, so this is seldom done.


So there you go! Now you know more about color vision than most conversations allow. Thanks!
