![]() There is no known way to prevent these from occurring.Īlthough it is not clear what causes retinal holes, one possibility is that some disruption of the blood supply causes the affected area to degenerate (atrophy, hence the name atrophic retinal holes). They are usually small, peripheral (outside the macula, which is the center part of the retina, responsible for the keenest aspect of our vision) and do not affect vision they are typically identified on a routine exam as yours was. Idiopathic (spontaneously occurring without a specific identified cause) atrophic retinal holes are pretty common, occurring in up to 5% of the population. ![]() Please give me more information about this condition.Ī: Although the eye is a pretty complex organ, considering the basics will be enough for today’s column. For us to see, light must be focused by the lens at the front of the eye through the clear gel-like fluid (called vitreous humor) in the eyeball so it can land on the "picture screen"-like retina. The retina is attached to an underlying support structure that holds it firmly in place, acting like the theatre wall that supports a movie screen to hold it flat. After the focused light falls onto the retina, the retina’s light-sensitive cells trigger nerve signals that are sent to the brain, enabling us to see.
