Acute angle-closure glaucoma is characterized by a sudden rise in intraocular pressure, which leads to a distinctive set of symptoms. Severe eye pain is often the most notable symptom, accompanied by a headache that can be quite debilitating. Patients frequently report blurred vision due to the rapid increase in pressure and potential corneal edema. Additionally, some may experience nausea and vomiting as a result of the intense pain and disorientation caused by the elevated intraocular pressure.

In contrast, the other symptoms listed are more indicative of different ocular conditions. Mild itching and redness typically occur with allergic conjunctivitis or other minor irritations, and floaters and flashes of light are commonly associated with retinal issues. Itchy eyes and excessive tearing often relate to allergic reactions or dry eye conditions. Therefore, the cluster of severe pain, headache, and blurred vision aligns precisely with the acute presentation of angle-closure glaucoma. Understanding these clinical features is essential for timely diagnosis and treatment of this ocular emergency.
