Etiology - A retinal tear occurs when the retina (light-sensitive tissue) rips due to factors like aging (posterior vitreous detachment - PVD), severe myopia (nearsightedness), trauma, rapid eye movements, genetics, or prior eye surgery.
Details - A retinal tear is typically caused by the vitreous (gel that maintains eye's shape) pulling on a weakened part of the retina, allowing fluid to leak. People who experience a retinal tear immediately become much more prone to a retinal detachment, which is an even more serious condition.
Treatment - A retinal tear, if detected before turning into a retinal detachment, is most commonly treated by two in-office procedures: photocoagulation and cryopexy, which each generate scar tissue around the retina to kickstart a blockage and repair of the original tear.
