Correct answer: A — Central retinal vein occlusion

Sudden visual loss with flame haemorrhages, cotton-wool spots, dilated tortuous veins, and disc oedema in a stormy fundus is CRVO. Risk factors include hypertension, diabetes, and glaucoma. Management involves intravitreal anti-VEGF injections for macular oedema. Regular monitoring for neovascularisation and neovascular glaucoma is essential.
