There are two main causes of eye pain in patients with hypertension: 1. The most common cause is the increase in perfusion pressure of the blood vessels in the orbit after the rise in blood pressure, which causes edema of the tissues around the eye, thus causing soreness and discomfort in the eye. For eye pain caused by this cause, the blood pressure should be adjusted, and the soreness of the eye will improve after the blood pressure is stabilized; 2. Eye pain in patients with hypertension may also be due to the elevated pressure inside the eye, mainly The manifestation is that the intraocular pressure is higher than 21 mmHg, and the visual field examination can reveal the defect of the visual field, that is, glaucoma. Due to the increase of intraocular pressure, it will cause damage to the intraocular tissues and will cause irreversible damage to the visual function, at this time, it is necessary to promptly reduce the intraocular pressure and protect the optic nerve. Therefore, patients with hypertension, in addition to visiting internal medicine to control blood pressure, also need to go to ophthalmology in a timely manner to further check intraocular pressure and visual field to exclude glaucoma.
