Any retinal tear or hole allows the liquid vitreous to seep between the retinal layers, separating the retina from its choroidal blood supply. Predisposing factors include myopia, intraocular surgery, and trauma. In adults, retinal detachment usually results from degenerative changes of aging, which cause a spontaneous retinal hole. Perhaps the influence of trauma explains why retinal detachment is twice as common in males. Retinal detachment may also result from seepage of fluid into the subretinal space (because of inflammation, tumors, or systemic diseases) or from traction that’s placed on the retina by vitreous bands or membranes (due to proliferative diabetic retinopathy, posterior uveitis, or a traumatic intraocular foreign body).
Retinal detachment is rare in children, but occasionally can develop as a result of retinopathy of prematurity, tumors (retinoblastomas), trauma, or myopia (which tends to run in families).
In the United States, approximately 10,000 people per year are affected by retinal detachments.

Any retinal tear or hole allows the liquid vitreous to seep between the retinal layers, separating the retina from its choroidal blood supply. In adults, retinal detachment usually results from degenerative changes of aging, which cause a spontaneous retinal hole.
Predisposing factors include myopia, cataract surgery, and trauma. Perhaps the influence of trauma explains why retinal detachment is twice as common in males.
Retinal detachment may also result from seepage of fluid into the subretinal space (because of inflammation, tumors, or systemic diseases) or from traction that’s placed on the retina by vitreous bands or membranes (from proliferative diabetic retinopathy, posterior uveitis, or a traumatic intraocular foreign body).
Retinal detachment is rare in children but occasionally can develop as a result of retinopathy of prematurity, tumors (retinoblastomas), or trauma. It can also be inherited, usually in association with myopia.
