Symptom 7. Changes in Pupil Size or Shape: The Subtle Clues of Uveitis
Uveitis can cause changes in the size or shape of the pupil, the dark circular opening in the center of the iris that controls the amount of light entering the eye. Inflammation can cause the iris to become sticky, preventing the pupil from constricting or dilating properly.
This can result in an irregularly shaped pupil, a pupil that does not respond to light as it should, or a difference in the size of the pupils between the two eyes (known as anisocoria). These changes can affect the amount of light entering the eye and may contribute to symptoms such as photophobia or blurred vision.
A thorough eye examination by an eye care professional can help detect these changes in the pupil and provide a more accurate diagnosis of uveitis. Treatment with corticosteroid eye drops or other anti-inflammatory medications can help reduce inflammation and restore normal pupil function.(7)
