From Taber's Medical Dictionary (used by MD's and nurses): "Retinal detachment is the separation of the inner sensory layer of the retina from the outer pigment epithelium, leading to loss of retinal function. Usually caused by a hole or break in the inner sensory layer that permits fluid to accumulate between the two layers". One of the reasons this occurs is, unfortunately, weakening of the eye structures due to aging. Can also be caused by injury to the eye. Either way, no answers yet for help in the medical field. I hope just one eye is effected, if it is you or a loved one having the problem. Coping techniques and how to adapt are the only answers right now. Good luck.
