The eye is like a camera...and the retina is like the film of the camera. Normally...the retina lines the inside of the eyeball...and is flat against the back wall of the eye.A retinal detachment occurs...when a tear forms in the retina...which then allows fluid from the cavity of the eye (the vitreous) to pass through the tear...and under the retina. This causes the retina to lift up and peel off the back of the eye (like wallpaper peeling off the wall). Patients experience a sudden loss of vision...with a dark shadow in the vision...in the area corresponding to the portion of the retina which is detached.
Treatment is a surgical emergency.
