Types of Retin-A

Learn about tretinoin (Retin-A, Atralin, Renova, Avita, Altinac) a drug used to treat moderate acne, wrinkles, and sun damaged skin.

There are three types of retinal detachment.Rhegmatogenous retinal detachment is the most common type of detachment. It is caused by tears or holes in the retina called retinal breaks. A retinal break allows fluid from the middle of the eye to pass through the tear and settle under the retina. As the fluid builds up under the retina, it pushes the retina away from the layer beneath it. See a picture of a detached retina.The most frequent cause of retinal tears is posterior vitreous detachment (PVD), a condition in which the vitreous gel separates from the retina. At points where the gel is more strongly attached to the retina, the vitreous gel can pull so hard that it tears the retina. Retinal tears occur most often on the sides (periphery) of the retina, because the vitreous gel is attached to the retina most strongly in those areas. Often harmless, posterior vitreous detachments usually result from normal changes in the vitreous gel that develop as the eyes age.Retinal breaks
