info
Acute Visual Loss
Sudden visual loss is an ophthalmic emergency. Key history: time of onset, unilateral vs bilateral, painful vs painless, pattern (central scotoma vs field defect vs total loss), age, vascular risk factors, MS history. ALWAYS check VA and pupils — RAPD (relative afferent pupillary defect) = optic nerve or retinal disease.
