to limit visual load and physical activity to some extent. Although this treatment is inappropriate for the repair of many retinal detachments, it is simpler and much less costly than scleral buckling. Retinal separation, the main reason for retinal separation is its ruptures that may be caused by the following factors: long-lasting or chronic inflammation of the iris or the uvea, advanced myopia that can lead to atrophic changes in the fundus, injuries, strenuous physical activity (jumps. The doctor injects a tiny gas bubble into the vitreous, a clear, gel-like substance between your lens and retina. Accessed March 1, 2018. If you have diabetes or high blood pressure, keep those conditions under control. If pneumatic retinopexy is unsuccessful, vitrectomy and/or scleral buckling still can be performed. The surgeon identifies the holes or tears either through the operating microscope or a focusing headlight (indirect ophthalmoscope). In the past, vitrectomy was reserved only for certain complicated or severe retinal detachments, such as those that are caused by the growth of abnormal blood vessels on the retina or in the vitreous, as occurs in advanced diabetes ; retinal detachments associated with giant. Small openings are made through the sclera to allow positioning of a fiberoptic light, an irrigation system, a cutting source (specialized scissors and a delicate forceps.
Retinal detachment (see the image below) refers to separation of the inner layers of the retina from the underlying retinal pigment epithelium (RPE, choroid). If your retina gets torn, the fluid inside your eye can leak underneath and separate the retina from its underlying tissue. Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from the layer of blood vessels that provides it with oxygen and nutrients.
The retina coordinates the optic systems of the eye and the visual sections of the brain it acquires and transmits information.

Formation of vitreoretinal bands traction on the vitreoretinal band during eye movements or as a result of sudden decrease in intraocular pressure retinal detachment, subretinal fluid accumulation without retinal tears. Initial changes in the retina are usually undetectable for patients. New York, NY: WebMD.
