Glaucoma is usually considered incurable, but its progression can be controlled, so patients with glaucoma should be followed up throughout their lives and monitored regularly for the development of intraocular pressure and visual function (including visual acuity and visual field) and the progression of the fundus. Specifically, whether glaucoma can be cured is related to what type of glaucoma the patient has and whether the disease is early or progressive or advanced. Glaucoma is a group of eye diseases with characteristic optic nerve damage and visual field defects, for which pathologically elevated intraocular pressure is one of the main risk factors. The level of elevated IOP and the ability of the optic nerve to tolerate pressure damage are associated with the onset and progression of glaucomatous optic nerve depression atrophy and its characteristic visual field defects. This is the definition of primary open-angle glaucoma and chronic closed-angle glaucoma. Therefore, for both types of glaucoma, early detection, early diagnosis and aggressive IOP control and optic nerve protection therapy can control the progression of glaucoma, due to the fact that early glaucoma is more likely to be treated successfully than when the lesion progresses to severe. This is easier said than done, so it is recommended that annual eye exams be performed over the age of 40 to detect suspected glaucoma early and to achieve the best possible early cure for glaucoma. For people at high risk for glaucoma with risk factors, such as family history of glaucoma, high intraocular pressure, high myopia, diabetes, history of eye trauma, long-term steroid hormone therapy, etc., examinations should be performed every 1 to 2 years after the age of 35. Then patients with diagnosed progressive and advanced open-angle glaucoma should be followed up with close IOP, visual field and fundus examination, and anti-glaucoma surgery should be performed promptly when drug treatment is not effective, and regular follow-up after surgery to monitor the development of the filter bubble, IOP and visual field and the progress of the fundus, then it is possible to maintain useful visual function during one’s lifetime. For patients with acute closed-angle glaucoma, blindness caused by acute closed-angle glaucoma can be avoided if patients seek prompt medical attention when they have symptoms. And the contralateral eye can be saved with a prophylactic YAG laser iridotomy. For patients with a family history of glaucoma with a shallow anterior chamber, regular monitoring of IOP and atrial angle changes and timely prophylactic YAG laser iridotomy are very effective in preventing the onset of chronic and acute angle-closure glaucoma, and most patients are thus cured.
