What is retinal edema?
Damaged eye blood vessels may leak fluid into the retina. The retina swells (edema) and vision may be affected. Some forms of edema absorb spontaneously and leave no permanent damage. Other forms tend to progress and must be treated with lasers. The purpose of laser treatment is to preserve current visual level. Only 15% of patients report improvement in quality of vision after treatment. Still, treatment is very important because it tends to reduce additional visual loss. Since treatment is often unable to restore lost vision, it is important to treat early, before much vision is lost. Diabetics can help preserve their vision by undergoing periodic eye exams and by seeking care promptly when any symptoms appear.
Retinal edema occurs when fluid and protein collects under the retinal layer of the eye. More detailed information about the symptoms, causes, and treatments of Retinal edema is available on net. You can visit at expelis reviews.
