Abstract
The retina is the complex neurosensory tissue of the eye and comprises several main layers, including Bruch’s membrane, retinal pigment epithelium, photoreceptor layer, external limiting membrane, outer nuclear layer, outer plexiform layer, inner plexiform layer, ganglion cell layer, nerve fiber layer, and inner limiting membrane at the vitreoretinal interface. Retinal detachment consists of separation of the neurosensory retina from the retinal pigment epithelium. There are three types of retinal detachment: rhegmatogenous, tractional, and exudative. Treatment for retinal detachment depends on the particular type of detachment. Exudative detachments involve fluid collections under the retina from neoplastic or inflammatory conditions and are not associated with a retinal break. These are generally managed nonsurgically. Tractional retinal detachment occurs when a fibrous or fibrovascular membrane from trauma or neovascularization mechanically pulls the retina away from the retinal pigment epithelium. Rhegmatogenous detachments occur when there is a full thickness break in the retina and fluid enters the subretinal space from the vitreous cavity. Both rhegmatogenous and tractional retinal detachments may be treated surgically. The main options for retinal detachment repair include scleral buckling, vitrectomy with pneumatic retinopexy or silicone oil injection, or a combination of these. These procedures have a common goal, which is to reappose the neurosensory retina to the retinal pigment epithelium. The imaging findings after the treatment of retinal detachment and other procedures pertaining to the retina and vitreous are described and depicted in the following sections.
