High intraocular pressure is glaucoma.

If the IOP is slightly elevated, there are no obvious clinical symptoms, and the visual field test does not find any defects in the center and periphery of the visual field, it may not be caused by glaucoma. If the IOP is significantly elevated, nausea, headache, eye swelling, blurred vision, etc., the visual field test finds that the visual field of both eyes is reduced, which may be caused by glaucoma.

If the IOP is high and glaucoma is related, timolol maleate eye drops, latanoprost eye drops, etc. can be used to reduce the IOP.
