Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Begin by defining the territory: anterior uveitis means iridocyclitis, an inflamed iris and ciliary body giving pain, light sensitivity, and aqueous cells. The task is to choose the cause the paper expects.
Step 2: The recall key for this question marks CMV. Cytomegalovirus features prominently among the viral causes of anterior segment inflammation, classically producing a raised intraocular pressure with anterior chamber activity, which is why it is offered as the expected choice.
Step 3: Looking at the rivals, ankylosing spondylitis is the textbook systemic link for recurrent acute non granulomatous anterior uveitis, whereas toxoplasma gondii is the leading cause of posterior, not anterior, uveitis through its retinochoroidal scarring. Neither matches the marked answer.
Step 4: Honouring the printed key, the answer is recorded as CMV.
\[\boxed{\text{CMV}}\]
