Photophobia

Photophobia, or light sensitivity, is a common symptom in ophthalmology characterized by discomfort or pain in response to light exposure. Individuals experiencing photophobia may find normal levels of light intolerable, leading to squinting, blinking excessively, or seeking shade or darkened rooms. This condition can result from various eye conditions such as corneal abrasions, uveitis, or infections like conjunctivitis. It can also be associated with systemic diseases like migraines, meningitis, or metabolic disorders.

The mechanism behind photophobia involves heightened sensitivity of the eyes to light due to either direct eye tissue damage or changes in neurological processing. Treatment involves addressing the underlying cause; for example, using antibiotics for infections or anti-inflammatory medications for uveitis. Management strategies include wearing sunglasses, adjusting lighting conditions, or using lubricating eye drops to alleviate symptoms. Patients experiencing persistent photophobia should seek evaluation by an eye care professional for proper diagnosis and management.
