In a study of five diabetic patients with persistent macular edema, breathing supplemental oxygen for three months reduced fluid buildup and swelling in the macula and, in some cases, improved visual acuity.  more

Facts about vitreous detachment
Most of the eye's interior is filled with vitreous, a gel-like substance that helps the eye maintain a round shape. There are millions of fine fibers intertwined within the vitreous that are attached to the surface of the retina, the eye's light-sensitive tissue. As we age, the vitreous slowly shrinks, and these fine fibers pull on the retinal surface. Usually the fibers break, allowing the vitreous to separate and shrink from the retina. This is a vitreous detachment.  more
