Cataract - Eye Disease

A cataract is an eye disease in which the clear lens of the eye becomes cloudy opaque, causing decrease in vision (clouding of the lens of the eye). Cataracts typically progress slowly to cause vision loss, and are potentially blinding if untreated. The condition usually affects both eyes, but almost always one eye is affected earlier than the other.

Early in the development of age-related cataract, the power of the lens may be increased, causing near-sightedness (myopia), and the gradual yellowing and opacification of the lens may reduce the perception of blue colours.

Facts About Cataracts

1. Cataracts are extremely common and most cataracts are a result of the aging process.
2. Although many cataracts are not significant enough to require treatment, surgical removal of cataracts is usually safe and effective, resulting in improvement of vision.
3. Cataract surgery should be performed when the visual loss from the cataract significantly impacts the lifestyle of the individual patient.

Glaucoma - Eye Disease

It’s a condition on eyes characterized by gradual loss of eyesight. Glaucoma occurs because of the high pressure in eyes cause damage the optic nerve, namely the nerves that transmit the shadow falls on retina to the brain.

Because of damaging optic nerve, there is a blind spot, at first occurs in the peripheral visual field. There are two types of glaucoma : open-angle glaucoma and angle-closure glaucoma. The most of types is chronic open-angle glaucoma.

There is unknown glaucoma, low tension glaucoma. In this type pressure of eye is within normal limits but optic nerve damage if it’s not had therapy, glaucoma can cause blindness in both eyes.
