![]() Definition: Distinctive milky white or opalescent appearance of the peripheral retina that is observed in many normal eyes when examined with scleral depression.Treatment: low risk for association with retinal detachment, so patients are examined every 1-2 years.Diagnosis: OCT shows white areas correspond to hyperreflective outer retinal layers and ellipsoid zone, no vitreous traction.Frequently causes confusion with subclinical RD and Retinoschisis but indentation clearly reveals that retina is still apposed to the RPE.Exact cause is unknown one school of thought states it to be a manifestation of peripheral vitreous traction while one believes it to be simply an abnormal reflex from a structurally normal VR interface. ![]() Characteristics: Whiter than the retina in white with pressure and the choroidal markings are almost obscured, found in post-equitorial region at the base of the vitreous and ora serrata, whiteness further accentuated with scleral depression, margins are sharply demarcated from normal retina.Prevalence: found in up to 30% of normal eyes, often bilateral, more frequently diagnosed in younger patients, may be associated with longer axial length.Definition: Distinctive white appearance of the peripheral retina without indentation and without mechanical stimulus.Treatment: should be treated when patients are symptomatic, or there is progressive retinal detachment threatening the macula.Diagnosis: OCT findings include intraretinal hyporeflective cavities with destruction and thickening of the RPE.Primary cause of retinal detachment in 0.05-2.5% of cases.Complications: may involve posterior pole, may lead to retinal detachment.Immobile with movement of eye and produces an absolute field defect.Characteristics: Lesion is a bullous elevation of peripheral retina, found in temporal segment.Prevalence: found in 2-7% of the general population, more common in patients 40 years and older and in hyperopic eyes.Definition: senile retinoschisis (SR) is the splitting of layers of the neurosensory retina by thick fluid.Intra-Retinal Degenerations Senile Retinoschisis Therefore, OCT should be utilized in the initial diagnosis, treatment, and follow-up for peripheral retinal degenerations. Peripheral OCT may further aid in differentiation between types of peripheral retinal degeneration as well associated complications including subclinical retinal detachment, retinoschisis, retinal tears and vitreoretinal adhesions or tractions. ![]() Such detail includes the structure, shape and depth of retinal degenerations. Optical coherence tomography (OCT) has been shown to greatly benefit in the diagnosis of peripheral retinal degenerations by characterizing structural elements.
