When high intraocular pressure is detected, it is recommended to go to the ophthalmology clinic of the hospital in time for a routine examination to identify whether it is hypermetropia or glaucoma. The examination includes atrial angle examination UBM or anterior chamber anguloscopy, visual field examination, fundus examination, central corneal thickness, and 24-hour intraocular pressure examination. If it is determined to be caused by glaucoma, early treatment to lower IOP is necessary to prevent irreversible damage to the optic nerve caused by high IOP. For primary glaucoma, topical IOP-lowering eye drops as well as systemic medications are usually considered. Topical eye drops, such as beta-blockers, adrenergic nerve agents, pupil shrinkers, carbonic anhydrase inhibitors, or prostaglandin eye drops. One or a combination of these is usually chosen. Beta-blocker eye drops are usually preferred, but caution should be exercised in patients with bradycardia. If it is found that the combination of eye drops does not control the IOP to the desired value, surgery may be required. In the case of an acute glaucoma attack, topical eye drops are used along with systemic treatment with hypertonic infusions. In the case of secondary glaucoma, such as secondary to keratoconus, iridocyclitis, lens-related, or traumatic, hormonal, or degenerative eye disease, etc., the primary disease needs to be treated, along with IOP-lowering eye drops as appropriate.
