Indentation gonioscopy showing a 'double hump' sign is characteristic of:
Answer: Plateau iris configuration
The double hump reflects the peripheral iris draped over anteriorly positioned ciliary processes, typical of plateau iris.
The definitive initial procedure for acute primary angle closure due to pupillary block, once the cornea clears, is:
Answer: Laser peripheral iridotomy
LPI equalizes pressure between the posterior and anterior chambers, relieving pupillary block.
The EAGLE trial found that, in PAC with IOP ≥30 mmHg or PACG, clear lens extraction compared with LPI was:
Answer: More effective and cost-effective
EAGLE showed clear lens extraction yielded better IOP control, quality of life, and cost-effectiveness than LPI.
In the Ocular Hypertension Treatment Study, which baseline factor was a strong independent predictor of conversion to POAG?
Answer: Thinner central corneal thickness
OHTS identified thinner CCT, along with older age, higher IOP, larger cup-to-disc ratio, and higher PSD, as predictive.
Which patient is at highest risk for hypotony maculopathy after trabeculectomy with mitomycin C?
Answer: Young myopic man
Young age, male sex, and myopia (thinner, less rigid sclera) increase risk of hypotony maculopathy.
A 6-month-old with epiphora, photophobia, enlarged corneas, and horizontal Descemet breaks most likely requires which first-line treatment?
Answer: Angle surgery (goniotomy or trabeculotomy)
Primary congenital glaucoma is surgical, with angle surgery as first-line therapy.
The Early Manifest Glaucoma Trial found that each 1 mmHg of IOP reduction from baseline reduced the risk of progression by approximately:
Answer: 10%
EMGT showed roughly a 10% reduction in progression risk per mmHg of IOP lowering.
