What is one common symptom of PACG?

Intense pain of the eye is a hallmark symptom of primary angle-closure glaucoma (PACG). This condition develops when the drainage structure of the eye, known as the angle, becomes blocked, leading to a rapid increase in intraocular pressure. The acute rise in pressure can cause severe, throbbing pain in the eye, which may also radiate to the forehead or temples.

In addition to intense eye pain, patients may experience other symptoms, such as blurred vision, headache, nausea, and vomiting. Recognizing intense eye pain as a symptom is crucial for timely intervention, as PACG can lead to permanent vision loss if not treated promptly. The need for immediate medical attention in the presence of such pain underscores its significance as a diagnostic feature of the condition.
