Eye Conditions

Macular Degeneration

Macular degeneration is the leading cause of vision loss in the Western world. Macular degeneration, sometimes known as AMD (Age-related macular degeneration) occurs in either dry (atrophic) or wet (exudative) forms. This disease only affects the central vision and rarely causes total vision loss.

Glaucoma

Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. When a significant number of nerve fibers are damaged, blind spots develop in the field of vision. Once nerve damage and visual loss occur, it is permanent.

Diabetic Rentinopathy

Diabetic retinopathy occurs when diabetes damages the tiny blood vessels in the retina. At first, most people do not notice any vision changes. This stage of the eye disease is known as non-proliferative diabetic retinopathy, and may be evident only through bulges in the blood vessels of the retina known as microaneurisms. These blood vessels may bleed or leak fluid into the surrounding retinal tissue.

Cataracts

A cataract occurs when clouding develops in the eye’s crystalline lens. The lens is a critical component of the eye, as it helps to focus light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, permitting objects to be seen clearly both close up and far away. All cells within the body degenerate and regenerate. As we age, however, proteins can build up on the crystalline lens and obstruct or deflect some of the light that should pass through it. Cataracts can occur as different types, including nuclear, cortical, or other forms.
