Old Retinal Detachment
In old retinal detachments, retinal thinning secondary to atrophy, secondary intraretinal cysts, subretinal demarcation lines and retinal holes or tears are seen.
Degenerative retinoschisis is a smooth, convex, thin and immobile elevation of layers of retina. However, demarcation lines and secondary cysts in the inner leaf are usually absent in retinoschisis.
Uveal Effusion syndrome
The uveal effusion syndrome is a rare, idiopathic condition characterized by choroidal detachment associated with exudative retinal detachment.
