Question:

A 26-year-old woman reports blurred vision and several moving shadows. Examination shows that inflammation is centered predominantly within the vitreous and peripheral retinal-ciliary region, with little anterior chamber activity. How should this uveitis be classified?

Options:

Correct Answer: Intermediate uveitis

Explanation: Intermediate uveitis is centered mainly in the vitreous and peripheral retina/ciliary body region rather than the anterior chamber or choroid.

Question:

A 30-year-old man has experienced three separate attacks of ocular inflammation over two years, with complete clinical inactivity between episodes. Which description best characterizes the course of his disease?

Correct Answer: Recurrent uveitis

Explanation: Recurrent disease presents as repeated inflammatory episodes separated by periods of inactivity rather than continuously persistent inflammation.

Question:

A 28-year-old patient presents with episodes of blurred vision and posterior ocular inflammation. Further history reveals repeated painful oral ulcers and recurrent genital ulceration. Which systemic disorder should be considered most strongly?

Correct Answer: Behçet disease

Explanation: The combination of recurrent oral and genital ulceration with intraocular inflammation is an important clinical pattern suggesting Behçet disease.

Question:

An 11-year-old girl receiving follow-up for chronic inflammatory arthritis is found to have anterior chamber inflammation during an ophthalmic assessment. Which systemic association is most relevant to this presentation?

Correct Answer: Juvenile idiopathic arthritis

Explanation: Juvenile idiopathic arthritis is an important systemic association of anterior uveitis in children and should be recognized in this clinical setting.

Question:

A 23-year-old man develops ocular pain, photophobia and anterior chamber inflammation several days after a blunt injury to the eye. Which etiological category best explains the inflammatory episode?

Correct Answer: Ocular trauma

Explanation: Trauma can disrupt intraocular tissues and trigger anterior uveal inflammation, so the temporal relation to eye injury is diagnostically important.

Question:

During slit-lamp examination of a patient with anterior uveitis, multiple inflammatory deposits are seen on the posterior surface of the cornea. On which structure are these deposits located?

Correct Answer: Corneal endothelium

Explanation: Keratic precipitates are collections of inflammatory cells deposited on the corneal endothelium during anterior uveal inflammation.

Question:

A patient with acute anterior uveitis has a painful red eye and a relatively small pupil before treatment. Which mechanism best accounts for the pupillary finding?

Correct Answer: Spasm of the inflamed iris sphincter

Explanation: Acute iris inflammation promotes sphincter spasm, producing the characteristic relatively miotic pupil seen in anterior uveitis.

Question:

A 35-year-old man with acute anterior uveal inflammation has a deep violaceous-red flush concentrated around the corneal limbus. Which vascular change best explains this appearance?

Correct Answer: Congestion of the anterior ciliary circulation

Explanation: Inflammation of the anterior uveal tract congests deeper anterior ciliary vessels, producing the characteristic circumcorneal or ciliary flush.

Question:

Fundus examination of a patient with posterior uveitis demonstrates an inflammatory lesion arising primarily from the vascular layer beneath the retina. The overlying retina is not the main site of inflammation. Which term best describes the lesion?

Correct Answer: Choroiditis

Explanation: Choroiditis describes inflammation centered in the choroid, whereas retinitis is primarily retinal and chorioretinitis involves both tissues.

Question:

A patient with posterior ocular inflammation notices a new localized dark area in the visual field. The cornea, anterior chamber and lens are clear. Which anatomical disturbance most directly accounts for this symptom?

Correct Answer: Focal retinal involvement

Explanation: Localized retinal inflammation can disturb function in a specific retinal region and produce a corresponding scotoma or area of visual distortion.

Question:

A 39-year-old patient with granulomatous intraocular inflammation reports prolonged cough and close household contact with a patient treated for pulmonary tuberculosis. Which investigation strategy is most appropriate?

Correct Answer: Tuberculosis-directed assessment

Explanation: Compatible ocular inflammation plus respiratory symptoms and significant exposure justify targeted evaluation for tuberculosis rather than unrelated screening tests.

Question:

A patient appears to have anterior uveitis on slit-lamp examination, but the reduction in visual acuity seems greater than expected from the anterior findings. Which examination should be performed to ensure significant posterior involvement has not been missed?

Correct Answer: Dilated fundus examination

Explanation: Dilated fundus examination assesses the vitreous, retina, choroid and optic disc and can identify posterior inflammation not visible on anterior-segment examination.

Question:

A patient is being assessed at the first visit for suspected uveitis. The ophthalmologist wants to quantify current functional impairment and provide a baseline against which subsequent change can be judged. Which assessment is most appropriate?

Correct Answer: Visual acuity in both eyes

Explanation: Recording visual acuity in each eye establishes the functional effect of uveitis and provides a baseline for detecting improvement or deterioration.

Question:

A patient with non-infectious anterior uveitis shows marked improvement in anterior chamber inflammation after topical corticosteroid therapy. Which action of the treatment best explains this response?

Correct Answer: Reduce inflammatory-cell activity and vascular leakage

Explanation: Corticosteroids suppress intraocular inflammatory activity and reduce vascular permeability, thereby reducing inflammatory cells and protein leakage.

Question:

A 58-year-old man develops a painful unilateral red eye shortly after a vesicular eruption affecting one side of his forehead. Slit-lamp examination confirms anterior uveal inflammation. Which infectious agent is most relevant?

Correct Answer: Varicella-zoster virus

Explanation: Varicella-zoster infection may cause anterior uveitis, particularly when ocular inflammation occurs in association with a unilateral dermatomal vesicular eruption.

Question:

A patient has confirmed non-infectious posterior uveitis requiring corticosteroid treatment. The ophthalmologist is deciding the most appropriate route of anti-inflammatory therapy. Which factor should principally guide this decision?

Correct Answer: Severity and anatomical involvement

Explanation: In non-infectious posterior disease, the required route of corticosteroid therapy depends mainly on how severe the inflammation is and which ocular structures are involved.

Question:

A patient has severe atypical posterior inflammation with progressive visual loss. Clinical findings strongly suggest infection, but routine systemic assessment has not identified the cause. Which additional diagnostic approach may be considered in this selected case?

Correct Answer: Selected ocular fluid testing

Explanation: In severe or atypical cases with strong suspicion of infection, ocular fluid may be examined using specialized microbiological or molecular methods.

Question:

A patient with recurrent ocular inflammation is subsequently diagnosed with a systemic inflammatory disorder requiring long-term treatment. Which management approach is most appropriate?

Correct Answer: Coordinate ophthalmic and systemic disease management

Explanation: When uveitis is associated with systemic inflammatory disease, control of both ocular and systemic inflammation requires coordinated specialist care.

Question:

Slit-lamp examination of a patient with anterior uveitis reveals large greasy keratic precipitates. No systemic diagnosis has yet been established. Which interpretation of this finding is most appropriate?

Correct Answer: A granulomatous pattern is suggested, but the cause is not established

Explanation: Large “mutton-fat” precipitates suggest granulomatous inflammation, but this pattern can occur with different diseases and does not establish a specific etiology by itself.

Question:

During discussion of a patient with widespread uveal inflammation, a student is asked to identify the structures forming the vascular middle coat of the eye. Which group is anatomically correct?

Correct Answer: Iris, ciliary body and choroid

Explanation: The uveal tract is the vascular middle coat of the eye and consists anatomically of the iris, ciliary body and choroid.
