Eye Conditions


A cataract is the clouding of the lens of the eye. Normally, light passes through the clear lens and is focused on the retina. However, as a result of the normal aging process or other factors, the lens becomes cloudy. This blocks light from passing through the lens and causes blurry or distorted vision. It can also cause glare, halos, spears on lights or double vision.

Glaucoma is a disease that damages the optic nerve. The optic nerve transmits visual information from the retina to the brain. When damage occurs to the optic nerve, blind spots develop. The blind spots can go undetected until the optic nerve becomes significantly damaged. Blindness occurs when the entire optic nerve is destroyed.

Diabetic Retinopathy

Diabetes Mellitus is a disease in which the ability of the body to produce and/or use insulin is abnormal resulting in high levels of blood sugar (serum glucose). This causes damage throughout the body including the eyes. High blood sugar damages blood vessels in the retina which is the nerve layer in the back of the eye which is responsible for sensing light and transmitting images to the brain. Damage to the retinal vessels is called diabetic retinopathy (DR).

Macular Degeneration

Macular degeneration is a disease of the macula. It is a small area in the retina at the back of the eye. The macula gives you the ability to see fine details and to do activities such as driving and reading. If your macula is not working properly, your vision may be blurry and have dark or distorted areas. Macular degeneration makes it difficult for you to see near and far and can make many activities such as reading difficult. It is the most common cause of severe vision loss in people older than 50 years of age.

Dry Eyes

Most of the time our eye constantly bathes itself in tears. When it is able to produce tears at a slow and steady rate, the eye is able to remain moist and comfortable. When the eye is not able to produce enough tears to keep it healthy and comfortable, the condition is known as dry eye.

Floaters and Flashes

If you sometimes see small specks or clouds, these are called floaters. You will often see them when looking in the distance or at a plain background like the blue sky or a blank wall. Floaters are tiny clumps of gel or cells inside the vitreous. The vitreous is the clear gel-like fluid that fills the inside of your eye. These tiny clumps may look like they in the front of your eye, however, they are actually floating inside of it. You are seeing the shadows they cast on the retina. Floaters can be many different shapes and sizes. They can appear as clouds, cobwebs, lines or dots.
