CATARACTS

When the crystalline lens of the eye loses its transparency, this condition is called a cataract. Light readily passes through a normally clear lens, producing a sharp image on the retina; when the lens becomes cloudy light can not pass through as easily and vision is impaired. Having a cataract is like trying to look through a foggy window.

A comprehensive eye examination can detect cataract formation. In time, cataracts may become so dense that good vision can no longer be achieved with prescription glasses. At that time, surgery may be the best option to restore vision.

GLAUCOMA

Glaucoma is a complex eye disease in which circulation of the fluid in the eye is disrupted. It is similar to the blockage of a kitchen sink, leading to overflow of water. This blockage of the fluid stops the process of re-absorption of the eye fluid leading to a rise in pressure within the eye. High pressure in the back of the eye causes damage to the optic nerve. The optic nerve is the "cable" that connects the eye to the brain. Once the optic nerve is damaged, permanent vision loss can occur.

Complete eye exams are necessary to determine if you have glaucoma or at risk for developing it. Evaluation for glaucoma includes measurement of your eye pressure, evaluation of the optic nerve, and a visual field test to measure peripheral vision.
