Patient Education

This page is dedicated to providing our patients with information on vitreoretinal diseases that we manage and treat.


The retina is the nerve tissue that lines the inner wall of the back half of the eye and receives the images focused on it. You might compare it to the film in a camera. The macula is the central portion of the retina which is essential for sharp vision. The vitreous is a transparent jelly located behind the lens and in front of the retina.


Many diseases involve the retina and cause or contribute to visual loss. Retinal abnormalities may be associated with nearsightedness, injury, diabetes, and aging. In some patients, rips or holes in the retina may lead to retinal detachment. With careful history taking, detailed examination of the eye and special tests, the cause of the problem can be determined. Treatments for diseases of the retina and vitreous may involve eyedrops, injections, lasers or freeze treatments in the office, or more extensive surgery in the hospital operating room.
