Retina
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.
