Which glaucoma medication is contraindicated in a patient with a history of severe reactive airway disease?
Answer: Timolol
Timolol is a nonselective beta-blocker that can cause bronchospasm and is contraindicated in severe asthma or COPD.
A patient undergoes trabeculectomy and presents on postoperative day 2 with a shallow anterior chamber, low IOP, and a large diffuse bleb. What is the most likely cause?
Answer: Overfiltration
A shallow chamber with low IOP and a large bleb in the early postoperative period is most consistent with overfiltration through the sclerostomy.
What is the target IOP reduction generally recommended for a patient newly diagnosed with normal-tension glaucoma showing progressive field loss?
Answer: 30% reduction from baseline
The Collaborative Normal-Tension Glaucoma Study demonstrated that a 30% reduction from baseline IOP slows progression.
Which minimally invasive glaucoma surgery (MIGS) device is placed in Schlemm's canal to enhance conventional aqueous outflow?
Answer: iStent
The iStent is a trabecular micro-bypass stent placed into Schlemm's canal to improve physiologic aqueous outflow.
A patient with neovascular glaucoma secondary to proliferative diabetic retinopathy presents with IOP of 48 mmHg. What is the most important initial treatment to address the underlying cause?
Answer: Intravitreal anti-VEGF injection followed by panretinal photocoagulation
Intravitreal anti-VEGF rapidly regresses neovascularization while panretinal photocoagulation addresses the underlying retinal ischemia driving the disease.
Which optic nerve head finding on OCT is most useful for detecting early structural glaucomatous damage before visual field changes appear?
Answer: Retinal nerve fiber layer thinning
RNFL thinning on OCT can detect structural glaucomatous damage before functional visual field loss becomes measurable.
