Retinal Detachment

A retinal detachment occurs when the retina (nerve
layer at the back of the eye which senses light and sends images to the brain) is pulled away from its normal position. The retina is unable to work properly when it is detached.

How is a retinal detachment caused?

The vitreous (clear gel that fills the middle segment of the eye) may pull away from its retinal attachment as one ages. The vitreous normally separates from the retina without complication. However, occasionally the vitreous pulls hard enough to tear the retina in one or more places allowing fluid to pass through the tear raising the retina off the back of the eye.

Retinal tears and subsequent detachment may also occur following trauma to the eye.  People who are highly myopic (nearsighted) or have a family history of RD have a greater risk of detachment.

Less common forms of retinal detachment may also occur. If eye disease has caused abnormal blood vessel growth and scarring inside the eye.  Such scar tissue may shrink and pull the retina off (traction detachment). Another type of detachment (exudative) can occur due to inflammatory conditions that affect the eye.

At Ophthalmology Associates we are skilled at examining the eye for all types of retinal problems.
