Intraocular pressure is the pressure of the contents of the eyeball on the interaction between the wall of the eyeball and the contents, and during intercourse, the patient’s intraocular pressure will rise. The main reason for the increase in intraocular pressure is that during intercourse, the patient’s parasympathetic nerve is excited, which can easily lead to pupil dilation, causing an obstacle to the drainage of atrial fluid inside the eye, and closing the angle of the atrium, thus leading to an increase in intraocular pressure. Patients with glaucoma may also experience increased intraocular pressure, causing optic nerve atrophy, visual field defects, and vision loss. Obstructed drainage of the aqueous humor inside the eyeball can cause a gradual increase in intraocular pressure. In daily life, we need to maintain a stable and optimistic mood, avoid nervous tension and excessive excitement. Ensure adequate sleep, do not stay in the dark place for a long time, to prevent the pupil is too large and cause intraocular pressure rise. Patients also need to participate in outdoor sports and cultural activities, because this can increase the supply of oxygen to the blood vessels in the fundus of the eye, reduce the accumulation of carbon dioxide in the blood, and avoid elevated intraocular pressure. Patients need to avoid prolonged head-down work and keep the bowel movement smooth, prohibit eating stimulating food, eat more nutritious and easy to digest food, do not drink strong tea and coffee and other stimulating beverages, which can avoid intraocular pressure increase. It is recommended that patients with abnormal intraocular pressure should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
