**Question:** All the following drugs are known to cause anterior uveitis except

A. Prednisolone
B. Corticosteroids
C. Aspirin
D. Nonsteroidal anti-inflammatory drugs (NSAIDs)

**Core Concept:**
Anterior uveitis is an inflammation of the iris and the anterior chamber in the eye. This condition can be caused by various factors, including infections, autoimmune disorders, and medications. Corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly associated with uveitis due to their immunosuppressive and anti-inflammatory properties. Prednisolone and NSAIDs are known to cause anterior uveitis.

**Why the Correct Answer is Right:**
Anterior uveitis is primarily caused by corticosteroids as they suppress the immune system, leading to an increased susceptibility to infections and autoimmune disorders. Prednisolone is a specific type of corticosteroid, and as such, it is more likely to cause uveitis as compared to other corticosteroids.

**Why Each Wrong Option is Incorrect:**
Option B (corticosteroids) is incorrect because it includes prednisolone, which is known to cause uveitis. Option C (aspirin) is incorrect because aspirin belongs to the NSAIDs group, and although it can cause uveitis, it is less likely compared to other NSAIDs. Option D (NSAIDs) is incorrect because they are also immunosuppressive and anti-inflammatory agents, which can lead to anterior uveitis. However, prednisolone is more likely to cause uveitis due to its specific corticosteroid nature.

**Clinical Pearl:**
It is essential for healthcare professionals to be aware of the potential side effects of immunosuppressive drugs like corticosteroids and NSAIDs. Ocular complications, such as anterior uveitis, can significantly impact a patient's quality of life and vision. Inform patients about these potential side effects when prescribing such medications and monitor for any ocular symptoms or signs during follow-up visits.
