Retina Vitreous · Central serous chorioretinopathy

Cscr

The scan shows a clear, fluid-filled pocket separating the neurosensory retina from the underlying retinal pigment epithelium (RPE) OCT (Optical Coherence Tomography) OCT-The first-line investigation. Key findings include: 1. Subretinal fluid (SRF) — the hallmark of CSCR; resolution can be tracked on serial OCT 2. Fibrin deposits — occasional band-like deposits in the subretinal space 3. Outer retinal dipping/sagging — may touch the RPE or a PED; its location often correlates with the leak site 4. Chronic changes — intraretinal cystic changes, hyperreflective dots, and elongated photoreceptor outer segments 5. Choroidal findings (pachychoroid spectrum) — EDI-OCT shows a thickened choroid (in both affected and fellow eyes), dilated outer choroidal vessels, and choriocapillaris thinning 6. PED — commonly seen, often adjacent to areas of choroidal hyperpermeability on ICGA 7. Double-layer sign — occasionally seen in chronic CSCR, though more typical of polypoidal choroidal vasculopathy (PCV); ICGA helps distinguish the two, as both lie on the pachychoroid spectrum 8. Hyperreflective outer retinal dots — correspond to tiny white dots seen on ophthalmoscopy
