Glaucoma Masterclass: 15 High-Yield MCQs on Open-Angle, Angle-Closure & Secondary Glaucoma

Fifteen single-best-response glaucoma questions, each with a six-second timer, a full rationale, a named source, a teardown of all three wrong options, and one rule to carry into the exam. This is not a quiz dump. Every question is built around a distractor that candidates actually pick under time pressure - the ocular hypertensive treated on the number alone, the prostaglandin started before SLT, the timolol given to an asthmatic, the fellow eye left untreated after an acute attack, the disc haemorrhage filed as benign. After each reveal, the three wrong answers are taken apart one at a time, so you learn the error rather than just the letter. Topics, in order: Ocular hypertension: who crosses the treatment threshold Open-angle glaucoma: SLT before the first drop Beta-blockers: asthma, bradycardia and heart block Prostaglandins: iris darkening, lashes and periorbitopathy Carbonic anhydrase inhibitors and sickle-cell trait Acute angle closure: the fellow eye needs an iridotomy Normal-tension glaucoma and the 30% target Steroid-induced glaucoma: stop the steroid first Neovascular glaucoma: PRP the ischaemic retina Pigment dispersion: the NICE SLT exception Pseudoexfoliation: weak zonules at cataract surgery Primary congenital glaucoma: operate early Advanced disease: trabeculectomy with mitomycin C Disc haemorrhage: a progression marker, not a benign finding Plateau iris after a patent iridotomy: iridoplasty Every question closes with a one-line rule, and the outro replays all fifteen. Every answer card prints its source on screen - NICE NG81, the LiGHT trial, OHTS, the Collaborative Normal-Tension Glaucoma Study and the AAO EyeWiki - so you can verify the claim rather than take it on trust. Where teaching has moved under the author, the video teaches the current guideline and names the retired version: the reflex to treat every pressure above 21, the prostaglandin-first habit that predates the 2022 NICE update, and the belief that a normal pressure excludes glaucoma. How to use it: pause on the question card, commit to an answer before the timer runs out, then read the rationale and the teardown. Score yourself out of 15. Eleven or more is board-ready. Corrections and source challenges are welcome in the comments - if a citation does not support the claim, say which one and it gets fixed.
