This presentation is most suggestive of: * Cataract formation Acute angle-closure glaucoma Retinal vein occlusion Uveitis Optic neuritis 4 Prostaglandin analogs (e.g., Travoprost) are often first-line therapy for glaucoma because they primarily work by: * Decreasing the production of aqueous humor at the ciliary body Increasing aqueous humor outflow through the uveoscleral pathway Reducing inflammation within the anterior chamber Enhancing blood flow to the optic nerve head Causing miosis to open the trabecular meshwork 5 Ocular hypertension is defined as: * Visual field loss confirmed by perimetry Glaucomatous damage present with normal IOP Optic disc cupping evident on examination Increased episcleral venous pressure IOP above 21 mmHg without optic nerve damage 6 Which surgical procedure involves creating a new drainage pathway by connecting the anterior chamber directly to the subconjunctival space, often resulting in a filtering bleb? * Trabeculectomy Cyclophotocoagulation (CPC) Goniotomy Viscocanalostomy Laser peripheral iridotomy (LPI) 7 The cup-to-disc ratio (C/D ratio) is an important clinical measurement used to assess: * Corneal curvature Anterior chamber depth Lens opacity Aqueous humor production rate Optic nerve head health 8 Which topical beta-blocker is typically avoided or used with caution in patients with asthma or severe COPD? * Dorzolamide Timolol Latanoprost Brimonidine Pilocarpine 9 Which structure is primarily responsible for draining aqueous humor from the anterior chamber in a healthy eye? * Vitreous body Ciliary body Lens capsule Trabecular meshwork and Schlemm\\\'s canal Iris 10 Which diagnostic tool is essential for objectively monitoring progressive optic nerve head changes over time? * Gonioscopy Pachymetry Tonometry Visual acuity testing Optical Coherence Tomography (OCT) 11 What is the most common type of glaucoma, characterized by a gradual, painless increase in IOP? * Primary open-angle glaucoma (POAG) Congenital glaucoma Pigmentary glaucoma Neovascular glaucoma Acute angle-closure glaucoma 12 Which visual field defect is classically associated with advanced glaucomatous damage? * Central scotoma Superior altitudinal defect Tunnel vision (complete peripheral loss) Bitemporal hemianopsia Nasal step and arcuate scotoma 13 Elevated Intraocular Pressure (IOP) primarily causes damage to which part of the eye in glaucoma? * Optic nerve Lens Cornea Macula Retina 14 What is the primary mechanism of action for Pilocarpine in treating open-angle glaucoma (though less common now)? * Increasing uveoscleral outflow Increasing episcleral venous pressure Constricting the pupil and mechanically pulling open the trabecular meshwork Inducing inflammation to clear debris Decreasing aqueous production 15 Which class of medication works by *decreasing* the production of aqueous humor? * Alpha-adrenergic agonists (e.g., Brimonidine) Cholinergic agonists (e.g., Pilocarpine) Rho kinase inhibitors (e.g., Netarsudil) Prostaglandin analogs (e.g., Latanoprost) Carbonic anhydrase inhibitors (e.g., Dorzolamide) 16 In pigmentary glaucoma, the IOP elevation is caused by the blockage of the trabecular meshwork by what substance? * Calcium crystals Pigment granules shed from the iris Hemosiderin deposits Inflammatory cells Proteinaceous debris 17 Which structure is damaged in secondary glaucoma caused by uncontrolled diabetes mellitus (neovascular glaucoma)? * Ciliary processes Choroid Schlemm\\\'s canal Trabecular meshwork due to fibrovascular proliferation Scleral spur 18 In normal-tension glaucoma (NTG), patients present with glaucomatous optic nerve damage despite IOP readings consistently being: * Fluctuating wildly throughout the day Above 30 mmHg Within the statistically normal range (e.g., <21 mmHg) Above 24 mmHg Elevated only during stress ← Previous Next → Submit Quiz ✓
