The retina is a thin sheet of nerve tissue in the back of the eye, where light rays are focused and images are transmitted to the brain. The center of the retina is called the macula. The vitreous is a gel-like substance that fills the eye and is attached to the retina in several areas including the macula and the optic nerve.
Problems with the retina can take different forms and treatments also vary.The vitreous can separate from the retina. This is called a posterior vitreous detachment (PVD). The majority of PVD’s have an uncomplicated course.
However, in a small percentage of patients, problems with the retina may develop after a PVD, such as a retinal tear, retinal detachment, epiretinal membrane or a macula hole. These issues generally need treatment fairly quickly to avoid vision loss.
Diabetes creates conditions that can also negatively impact one’s vision and diabetics should be particularly vigilant about having regular eye exams with a board certified retinal specialists like the ones at Concord Eye Center.
