Glaucoma can cause conditions such as optic papillary atrophy, visual field defects, and vision loss. Glaucoma is very damaging to the eye and the damage to visual function is irreversible. The key to treating glaucoma is to get the eye pressure lowered so that the damage to the internal tissues from the eye pressure will be reduced. Depending on the type of glaucoma, the treatment methods are different, mainly in the form of medication and surgery. For example, acute glaucoma is mainly treated by using topical eye drops or even systemic medication to lower the intraocular pressure in a timely manner. Congenital glaucoma, on the other hand, needs to be treated by surgery so as to achieve better results. Glaucoma is a lifelong disease and blinding eye disease, so early detection and early treatment is the key, and most patients can maintain useful visual function if treated early.
