Peripheral Retinal Degenerations: A Ready Reckoner
Introduction Peripheral retinal degenerations (PRD) are considered a risk factor for rhegmatogenous retinal detachment (RRD) [1, 2]. The annual incidence of RRD varies between 6.3 and 18.2 cases per 100,000. RRD develops when liquefied vitreous humor accelerated by rotary eye movements passes through retinal tears or retinal holes into subretinal space and detaches neurosensory retina from the underlying pigment epithelium. PRDs when missed during retinal examination can lead to vision threatening complications.3 Classification [3] Retinal detachment Retinal drusen Lattice with holes Full-thickness tear Honeycomb degeneration Preretinal fibrosis Retinal tuft Unifocal hypertrophy of the retinal pigment epithelium Hemorrhage Grouped congenital hypertrophy of the retinal pigment epithelium (“bear tracks”) Pearl degeneration Retinoschisis Atrophic retinal hole Snail-track degeneration Dark-without-pressure Snowflake degeneration White-without-pressure Flap tear Operculated retinal tear Pav
