The retina lines the inside of your eye and is responsible for sending images to your brain. This is similar to the film inside of a camera. When the retina pulls away from the eye, a retinal detachment occurs.
The symptoms may include flashing lights, a “curtain” over the vision, or many floaters. Sometimes these symptoms are present without a retinal detachment. An immediate exam is necessary if you experience these symptoms.
If a retinal tear is diagnosed, treatment is done with a laser or freezing technique (cryotherapy) that seals the detachment. This will usually prevent a retinal tear. If the retina is detached, surgery is performed to place the retina back into position.
