Vision Loss Causes

Forms Of Vision Loss And Their Causes

The other forms of vision loss are seldom reversible; the treatment is meant to stabilize the condition of the eye and preserve existing vision if possible. Macular degeneration occurs with loss of circulation or with weakened seeping blood vessels in the back of the eye (called the macular portion of the retina).

If you have macular degeneration, you may notice that straight lines look as though they are wavy or moving. Looking your friend or loved one directly in the face may be difficult because the person's nose and eyes may be distorted or missing in your vision. It is unlikely that you will lose all of your vision, however. Normally, you will have peripheral vision (seeing out of the "corner"' of your eye) which will help you in walking safely.

Diabetic retinopathy occurs when diabetes complicates the circulation of the eye, making new or extra blood vessels which have weak leaky walls. This may effect any portion of the retina. Hemorrhages due to diabetic retinopathy or macular degeneration are commonly treated by laser surgery. The laser does not restore vision, but repairs the leak and inhibits the cloudiness of vision occurring due to the leaking of blood into the clear fluid inside the eye.

Diabetic Retinopathy and Macular Degeneration

Glaucoma is associated with increased fluid pressure in the eye and loss of peripheral vision. The healthy eye ideally manufactures new fluid and drains out the old, keeping an even pressure. Damage to the eye can occur when too much fluid is made or if the excess is not released appropriately. Treatment most likely involves eye-drops, but may include surgical procedures, including the laser.

If you experience any sudden changes in vision, see your eye doctor right away. Request information or instruction to modify your lifestyle and remain independent. Finally, remember that you are not alone; you have many peers and available resource services.
