The most common causes include infections, inflammatory conditions, and chronic diseases such as glaucoma. The character of the symptom — including onset, duration, severity, and associated features like blurred vision — provides crucial diagnostic clues.

Initial management focuses on identifying and treating the underlying cause. Lifestyle modifications, over-the-counter medications, and specialist referral may all play a role depending on the severity and etiology.

Seek immediate medical attention if symptoms are sudden, severe, or accompanied by warning signs including high fever, neurological changes, difficulty breathing, or persistent chest pain. Early diagnosis significantly improves outcomes.
