Retinal detachment is the separation of the retina from the pigment epithelium. It is often caused by holes or tears in the retina, by a tumor, or by fluid pressure in the area.
Retinal detachment occurs among the elderly or, sometimes, following head or eye injuries. There is also a higher rate of incidence among the extremely myopic. B.C. MSP coverage for such patients allows for more frequent eye exams.
In some cases it can be surgically treated. Apart from a sudden loss of vision, other (early) symptoms may include light flashes or an unusual number of “spots and floaters.”
