Separation of RPE (Retinal pigmented epithelium) from neurosensory retina.
Retinal detachment (RD) | Description | Examination finding |
Rhegmatogenous RD (Rhegma = Break) Retina continuity break | Tear (due to traction)- • Horseshoe shaped RD • M/C cause is PVD • PVD is physiological (normal) in old age Hole (after degeneration)- • Lattice degeneration • Snail track degeneration | • Corrugated appearance • Schaffer’s sign / Tobacco dust • Undulating movement • Photopsia • Floaters |
Tractional RD (In vascular disease) | – | • Concave RD • Tractional bands • Immobile • Photopsia + / – • Floaters absent |
Exudative / Serous RD (Due to choroid pathology) | Causes:- • Inflammation – Posterior scleritis • Vascular – Central serous chorioretinopathy • Neovasculaziation – Wet ARD • Tumor Systemic- • Renal hypertension • Pregnancy induced HTN (PIH) | • Convex RD • Mobile (due to shifting fluid) • Leopard spots (pigment deposition in subretinal space) • No photophobia • Floaters + / – |
PVD- Posterior vitreous detachment
RD- Retinal detachment
HTN- Hypertension
