Highly comparable to a camera, the eye is a fascinating and complex optical system. Light enters the eye through the powerful transparent focusing surface of the cornea. It continues through clear aqueous fluid and travels through a small opening called the pupil.
Muscles in the iris, the colored part of the eye which surrounds the pupil, constrict or relax, expanding and contracting the pupil to regulate the light that enters the eye. Light rays are then focused through the lens, which sits behind the pupil. Light proceeds through the vitreous, a clear jelly-like substance in the center of the eye, giving it form and shape.

Next, the rays land on the light-sensitive retina, the part of the eye which is similar to film in a camera, forming an upside-down image. The retina converts this image into an electrical impulse which travels along the optic nerve to the brain, where it is finally interpreted as an upright image.
Dr. Ronald Klug specializes in diseases of the retina. He provides care for patients with a variety of eye conditions which require extensive knowledge, experience and expertise in treatment.
