Glaucoma and cataract

Glaucoma is mainly caused by the outflow of aqueous humor, which leads to an increase in intraocular pressure and thus shows irreversible visual impairment. However, cataracts are mainly caused by clouding of the lens, resulting in occlusion of things, thus causing visual impairment. Glaucoma visual impairment is irreversible, so it must be diagnosed early, because once obvious visual impairment occurs, any subsequent aggressive treatment, the previous damage is impossible to reverse. Cataract patients are lucky enough to be diagnosed and treated in ophthalmology when they are more serious, and the effect after treatment is still very good.
