1

Hallmarks retinal venous occlusion

either CRVO (central) or BRVO (branch) Sudden visual loss against a background of vascular risk factors Painless Haemorrhages across the retina in a 'blood storm' pattern Can be treated with VEGF, intravitreous steroid implant, laser

2

Hallmarks CRAO

Sudden visual loss -> fundoscopy pale retinal with absence of vessels cherry red spot may be observed

3

Difference conjunctivitis, scleritis, episcleritis, anterior uveitis and acute closed-angle glaucoma

Conjunctivitis -> eye pain, grittiness and mucopurulent discharge - Tx chloramphenicol Epicleritis -> Red eye with localised changes with mild discomfort and no loss of visual acuity - Tx artificial tears or topical steroid in resistant cases Scleritis -> Severe pain and photophobia and progressive visual loss Ant. uveitis -> blurred vision and headache Acute closed-angle glaucoma -> ophthalmic emergency, severe pain, haloes around light source, photophobia and eye watering

4
