Explanation - Sarcoidosis often causes chronic, bilateral, granulomatous uveitis due to systemic granulomatous inflammation.
Correct answer is: Sarcoidosis

Q.7 Which complication is most likely to result from chronic uveitis?

Glaucoma
Myopia
Retinitis pigmentosa
Macular degeneration
Explanation - Chronic uveitis can lead to secondary glaucoma due to trabecular meshwork obstruction or steroid-induced ocular hypertension.
Correct answer is: Glaucoma

Q.8 Which of the following is a common presenting symptom of uveitis?

Pain, redness, photophobia
Painless visual field loss
Night blindness
Floaters without redness
Explanation - Patients with anterior uveitis typically present with eye pain, redness, and sensitivity to light (photophobia).
Correct answer is: Pain, redness, photophobia

Q.9 Which type of uveitis is more likely to cause severe vision loss if untreated?

Anterior uveitis
Intermediate uveitis
Posterior uveitis
Iritis only
Explanation - Posterior uveitis affects the retina and choroid and can cause permanent vision loss if untreated.
Correct answer is: Posterior uveitis

Q.10 Which laboratory test is most useful in suspected HLA-B27 associated uveitis?

HLA-B27 typing
ANA
RPR
ACE level
Explanation - HLA-B27 testing helps confirm the association with spondyloarthropathies in acute anterior uveitis.
Correct answer is: HLA-B27 typing

Q.11 Which feature differentiates granulomatous from non-granulomatous uveitis?

Presence of mutton-fat keratic precipitates
Pain severity
Laterality
Presence of floaters
Explanation - Granulomatous uveitis shows large, greasy 'mutton-fat' keratic precipitates on the corneal endothelium, unlike non-granulomatous uveitis.
Correct answer is: Presence of mutton-fat keratic precipitates

Q.12 Which ocular imaging modality is most helpful in evaluating posterior uveitis?

Fluorescein angiography
Slit-lamp exam
Tonometry
Corneal topography
Explanation - Fluorescein angiography helps detect retinal and choroidal lesions, vascular leakage, and inflammation in posterior uveitis.
Correct answer is: Fluorescein angiography

Q.13 Which of the following is a common treatment for acute anterior uveitis?

Topical corticosteroids
Antibiotic eye drops
Laser photocoagulation
Antiviral oral therapy
Explanation - Topical corticosteroids reduce inflammation in anterior uveitis and are the first-line therapy.
Correct answer is: Topical corticosteroids

Q.14 Which complication is directly associated with posterior synechiae in uveitis?

Irregular pupil
Retinal detachment
Cataract
Macular edema
Explanation - Posterior synechiae are adhesions between the iris and lens, causing an irregular pupil and potential secondary glaucoma.
Correct answer is: Irregular pupil

Q.15 Which infectious cause should be suspected in immunocompromised patients with necrotizing retinitis?

Cytomegalovirus
Streptococcus pneumoniae
Toxocara
Varicella zoster virus
Explanation - CMV retinitis is common in immunocompromised patients, such as those with AIDS, and presents as necrotizing retinitis.
Correct answer is: Cytomegalovirus

Q.16 Which systemic therapy is indicated for severe or refractory uveitis?

Oral corticosteroids
Topical antibiotics
Lubricating eye drops
Beta-blockers
Explanation - Severe or refractory uveitis may require systemic corticosteroids or immunosuppressants to control inflammation.
Correct answer is: Oral corticosteroids

Q.17 Which uveitis type is most commonly associated with multiple sclerosis?

Intermediate uveitis
Anterior uveitis
Posterior uveitis
Panuveitis
Explanation - Intermediate uveitis, affecting the vitreous, is often associated with demyelinating diseases like multiple sclerosis.
Correct answer is: Intermediate uveitis

Q.18 Which of the following drugs is known to cause drug-induced uveitis?

Cidofovir
Metformin
Lisinopril
Atorvastatin
Explanation - Cidofovir, an antiviral, is known to cause anterior uveitis and increased intraocular pressure in some patients.
Correct answer is: Cidofovir

Q.19 Which ocular structure, if affected in uveitis, can lead to cystoid macular edema?

Macula
Lens
Cornea
Optic nerve
Explanation - Inflammation in uveitis can cause fluid accumulation in the macula, leading to cystoid macular edema and vision loss.
