Glaucoma
Glaucoma
is an eye disease where the pressure inside the eye becomes too high resulting
in progressive damage to the main nerve of the eye (the optic nerve).  This
progressive damage initially causes a gradual loss of side vision that is
not noticeable until it is very advanced. Untreated glaucoma will eventually
cause blindness. Most forms of glaucoma produce no noticeable symptoms until
major, irreversible nerve damage has already occurred. This is the real
danger of the disease. Read more...
Diabetic
Retinopathy
Diabetes is a condition in which the body's ability to process and store
sugar has been impaired. Among the characteristics of the disease are gradual
changes in blood vessels. Diabetic retinopathy is a complication of diabetes
caused by the deterioration of blood vessels nourishing the retina at the
back of the eye. These blood vessels become damaged due to persistantly
elevated blood sugar. The damaged blood vessels can leak blood and fluid
resulting in swelling of the retina. This swelling can lead to permanant
visual loss. Read more...
Macular
Degeneration
The thin inner layer of eye is called the retina. It is like the "camera
film" of the eye. The central portion of the retina that gives allows
us to see detail vision such as reading and recognizing peoples faces is
called the macula. The rest of the retina allows for "side vision"
but is not able to distinguish fine detail. A person without good macular
function is able to walk around without bumping into things as well as take
care of their daily needs such as bathing, cooking, and eating. However,
they are unable to read a newspaper, recognized details of a persons face
or see highway signs while driving.
