| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the most common presenting symptom of cataracts? | Progressive painless decrease in vision, often described as clouding or opacity in the visual field. | Think of clouded vision as a foggy window. |
| 2 | Which age group is most commonly affected by age-related macular degeneration (AMD)? | Individuals over 50 years old, with risk increasing with age. | Think '50 and over' for AMD prevalence. |
| 3 | What is the primary risk factor for primary open-angle glaucoma? | Elevated intraocular pressure (IOP), often asymptomatic in early stages. | Think 'pressure' and 'silent' in early glaucoma. |
| 4 | Describe the cardinal clinical feature of acute angle-closure glaucoma. | Sudden onset of severe ocular pain, headache, nausea, visual halos, and a mid-dilated non-reactive pupil. | Think 'sudden, painful, and red eye.' |
| 5 | What key sign differentiates normal-tension glaucoma from other types? | Progressive optic nerve damage and visual field loss despite normal intraocular pressure. | Normal pressure, abnormal damage. |
| 6 | Which ocular finding is characteristic of diabetic retinopathy, a common complication associated with diabetes? | Microaneurysms, dot-blot hemorrhages, and neovascularization on fundoscopic exam. | Think 'tiny aneurysms' and 'new vessels.' |
| 7 | What is the typical visual symptom of age-related macular degeneration? | Central vision loss or distortion, such as straight lines appearing wavy. | Remember 'central vision' is affected. |
| 8 | Which eye disorder is characterized by a 'cupping' appearance of the optic nerve? | Glaucoma, particularly in advanced stages with increased intraocular pressure. | Cupping = increased pressure damage. |
| 9 | Name a common sign of conjunctivitis. | Redness, irritation, and discharge from the eye, often with crusting in bacterial conjunctivitis. | Red eye with discharge. |
| 10 | What distinguishes dry age-related macular degeneration from the wet form? | Dry AMD is characterized by drusen and atrophic changes in the macula, while wet AMD involves neovascularization and rapid vision loss. | Dry = slow, wet = rapid. |
| 11 | Which test is primarily used to measure intraocular pressure? | Tonometry. | Think 'pressure' with a 'tono' meter. |
| 12 | What is the main goal of glaucoma management? | Lowering intraocular pressure to prevent optic nerve damage and preserve vision. | Control pressure, protect optic nerve. |
| 13 | Name an important symptom of retinal detachment. | Sudden appearance of floaters, flashes of light, and a curtain-like shadow over the visual field. | Floaters and flashes = detachment warning. |
| 14 | Which eye disorder presents with 'floaters' and 'flashes' as key symptoms? | Retinal detachment or vitreous hemorrhage. | Floaters and flashes are warning signs. |
| 15 | What is the characteristic appearance of a cataract on slit-lamp examination? | Opacity or clouding of the lens, often with a shiny or cloudy appearance. | Lens cloud = cataract. |
| 16 | Which ocular condition is characterized by optic nerve cupping and peripheral visual field loss? | Glaucoma. | Cupping and peripheral loss go hand-in-hand. |
| 17 | What are common symptoms of age-related macular degeneration? | Blurred or distorted central vision, difficulty reading or recognizing faces. | Central vision loss affects detailed tasks. |
| 18 | How does open-angle glaucoma typically present in early stages? | Asymptomatically, with gradual optic nerve damage and peripheral visual field loss. | Silent, slow progression. |
| 19 | Name a common feature of hypertensive retinopathy seen on fundoscopy. | Arteriolar narrowing, arteriovenous nicking, and flame-shaped hemorrhages. | Hypertension affects retinal vessels. |
| 20 | What is the hallmark of central retinal artery occlusion? | Sudden, painless, profound vision loss with a pale retina and cherry-red spot at the fovea. | Cherry-red spot = emergency. |
