Clinical Ophthalmology (Advanced)
The Advanced Clinical Ophthalmology domain tests specialist-level reasoning across cornea, glaucoma, retina, uveitis, neuro-ophthalmology, pediatrics, oculoplastics, and ocular oncology, emphasizing triage, investigation choice, staging, and definitive management.
Core rules and concepts
- Triage red flags: painful red eye with reduced vision, sudden painless visual loss, leukocoria, relative afferent pupillary defect, or orbital signs after trauma need urgent assessment.
- Choose investigations to answer a management question: OCT for macular edema, visual fields for glaucoma, B-scan when fundus is obscured, CT for orbital fracture or intraocular foreign body, and biopsy for atypical or steroid-resistant uveitis (masquerade).
- Stage before treating: center-involving diabetic macular edema is treated with anti-VEGF, while proliferative diabetic retinopathy needs panretinal photocoagulation; acute angle closure needs immediate IOP lowering and laser peripheral iridotomy to both eyes.
- Link findings to systemic disease: uveitis may signal sarcoidosis, HLA-B27 disease, or JIA; visual loss over age 50 with headache or jaw claudication suggests giant cell arteritis and needs urgent ESR/CRP and high-dose corticosteroids before biopsy.
Worked example
An 82-year-old reports sudden painless loss of vision in the left eye. Acuity is counting fingers, there is a relative afferent pupillary defect, and fundoscopy shows a pale, swollen retina with a cherry-red spot. The diagnosis is central retinal artery occlusion. Because the patient is over 50, ask for headache, scalp tenderness, and jaw claudication. If giant cell arteritis is suspected, start high-dose intravenous corticosteroids immediately and arrange temporal artery biopsy; do not wait for results. If GCA is not suspected, lower IOP and consider ocular massage, but counsel that visual recovery is poor. This hinges on distinguishing arteritic from nonarteritic occlusion, because only the former changes systemic management.
Traps that cost marks
- Treating every diabetic macular edema with focal laser; center-involving edema requires anti-VEGF.
- Missing giant cell arteritis because the fundus looks like a typical artery occlusion.
- Dilating a patient with a shallow anterior chamber and acute angle closure.
- Starting corticosteroids for uveitis before excluding infection or lymphoma when the presentation is atypical.
