Glaucoma can be photophobic, so the eyes are uncomfortable in bright light. Glaucoma is a series of symptoms caused by elevated intraocular pressure. If the symptoms are not obvious in the early stage, there may be occasional swelling and pain in the eye and soreness at the root of the nose, which will return to normal after rest. However, if there are many small attacks, it may cause acute grand mal attacks, which usually manifest as obvious eye distension, headache, dizziness, nausea, vomiting, and rapid loss of vision. Once the above symptoms appear, you need to go to the hospital early for relevant examinations, including visual acuity, intraocular pressure and fundus. After diagnosis, you need to give IOP lowering treatment and choose medication to control it early, such as brinzolamide eye drops and carteolol eye drops. If conservative treatment is not effective, surgical treatment can be considered. Conventional anti-glaucoma surgery includes trabeculectomy and peri-iridotomy. If symptoms are mild, laser iridotomy may also be performed.
