causes of a detached retina
Retinal detachment - Causes. Causes of retinal detachment. The most common cause of retinal detachment is tiny breaks developing inside the retina. The breaks allow the fluid found between the retina and the lens of the eye to leak underneath the retina. A build-up of fluid can cause the retina to pull away from the blood vessels that supply it with blood.
The retinal tear that triggers a retinal detachment sometimes is caused by trauma. More often, it is caused by a change in the gel-like consistency of the vitreous fluid that can occur as a part of aging. This age-related change can occur unpredictably in older people, and there is no way to prevent it.
