Question
What are the early symptoms of glaucoma?
Answer
The early symptoms of glaucoma can vary depending on the type. For primary angle-closure glaucoma, during an acute attack, patients may experience obvious eye pain, swelling, and headache, and some may even reappear with nausea, dry heaves, and loss of appetite. At this time, many patients may think they are experiencing gastrointestinal or head problems and some may go to the gastroenterology or neurology department for follow-up. In fact, these discomforts are often caused by a sudden increase in intraocular pressure. In such cases, it is advisable to seek ophthalmic care for appropriate treatment as soon as possible.
