角膜(inner cornea) is a disease in which the function of regulating intraocular pressure is impaired, resulting in abnormally high eye pressure, which causes visual impairment and changes in retinal morphology. It is named because the pupil is somewhat greenish.

One afternoon, Grandma Wang suddenly felt that her eyes were blurry. Her family realized the seriousness of the situation and immediately took her to the hospital for ophthalmology. The ophthalmology professor at the hospital finally diagnosed Grandma Wang with acute glaucoma.

The professor pointed out that when symptoms such as headaches and vomiting appear, one should not assume that it is necessarily a gastrointestinal disease, but it could also be a precursor to an acute glaucoma attack, especially during seasonal changes or emotional fluctuations.

In fact, the main symptoms of acute glaucoma are eye soreness, pain, and sometimes headaches and vomiting, which can easily be confused with common gastrointestinal diseases. In addition to temperature factors, the patient's own abnormal eye development and emotional fluctuations are also triggering factors. In addition, the elderly often overuse their eyes, such as reading for long periods of time, which can also trigger glaucoma.
