PERIPHERAL RETINAL DISEASES
Rhegmatogenous Retinal Detachment
Retinal detachment is the separation between the neurosensorial layers of the retina and the retinal pigment epithelium. Rhegmatogenous retinal detachment is the most common type of retinal detachment. It is caused by a retinal break, allowing access of a liquefied vitreous gel to the potential subretinal space.
Symptoms are variable. Rhegmatogenous retinal detachment is usually preceded by posterior vitreous detachment causing photopsia and floating opacities. Post-detachment symptoms include blurred vision, metamorphopsia, visual field defects and/or loss of central vision.
Predisposing factors for this disease include high myopia, aphakia, pseudoaphakia, family background and inflammation.
