| Age-Related Macular Degeneration (AMD) & the Aging Population |
As the baby boomer cohort approaches retirement age, vision loss and illness among the elderly will reach near-crisis proportions. Aging is the greatest risk factor for sight loss, and the leading cause of that loss is age-related macular degeneration (AMD), a condition that causes irreversible damage to vision.
At the back of the eye, there is a thin layer of light-sensitive tissue called the retina. Light is focused behind the retina onto a small spot called the macula. The macula then proces... Read More

In the darkyour pupil enlarges to allow more light into your eye and in the lightit decreases in size.
Light from an object passes through the clear window of the eyeknown as the cornea. The amount of light allowed into the eye is controlled by the pupilwhich opens and closes similarly to the workings of a camera shutter. In the darkyour pupil enlarges to allow more light into your eye and in the lightit decreases in size. Internal muscles con... Read More

Angle-Closure Glaucoma
Think of your eye as a sinkin which the faucet is always running and the drain is always open. The aqueous humor is constantly circulating through the anterior chamber. It is produced by a tiny gland called the ciliary body that is situated behind the iris. It flows between the iris and the lens and after nourishing the cornea and lensflows out through a very tiny spongy tissue called the trabecular meshwork. The trabecular meshwork is situated in the a... Read More

| Anisocoria |
Anisocoria is a condition where the pupils are unequal in size. The pupil is the central black aperture of the eye. Normally, the pupil size reacts automatically to the amount of light entering each eye. Pupil diameter is generally in a range of 3-4 millimeters, and most often, pupils are equal in size. It is not uncommon, and without concern, for people to have small observable differences in pupil size from birth. ... Read More

| Atrophic Retinal Holes |
Atrophic Retinal Holes are thought to be caused by thinning areas of the retina and aging changes of the vitreous humor.
The retina is the light-sensitive layer lining the back of the eye that receives visual images. The retina is like the film in a camera; millions of light-sensitive receptors receive optical images and then send electrical signals to the brain to be seen. Like most tissues in the bodythe retina is susceptible to changes due to agingand it does not take... Read More
