Retinal Detachment

If the eye is thought of as a camera, the retina is the film upon which images form. The proper placement of the film is critical for pictures to be formed. A retinal detachment is a separation of the retina from the back tissues of the eye. The retina cannot function unless it is properly apposed to these tissues. It is caused by a tear or hole in the retina which allows fluid to enter the space behind the retina and lift it from its normal position.

The symptoms of a retinal detachment include flashing lights, the new onset of floaters, and a gray curtain blocking one's vision. This is a serious problem that requires immediate attention. Treatment options include laser (for retinal tears) and surgical repair. The timing of repair depends upon the area of retina involved as well as the duration of symptoms.
