Which of the following is a symptom of iritis?

• A. Photophobia
• B. Stye
• C. Foreign body sensation
• D. Eye discharge

Answer: (A)

Photophobia, or sensitivity to light, is a common symptom of iritis, which is an inflammation of the iris, the colored part of the eye. This condition can cause significant discomfort and lead to an increased awareness of light, making bright environments particularly bothersome. Along with photophobia, patients may experience pain, redness, and blurred vision.

The other options provided represent different eye conditions or symptoms unrelated to iritis. For instance, a stye is an infection of the eyelid gland and is characterized by localized swelling and tenderness. A foreign body sensation might describe a feeling of something in the eye, which can occur due to various reasons, but it’s not specifically linked to iritis. Eye discharge more commonly points to infections such as conjunctivitis rather than inflammation of the iris. Thus, photophobia stands out as the definitive symptom of iritis.
