Suspected of elevated intraocular pressure, the patient can feel the hardness of the eye by touching the eye with the finger, and compare it with the hardness when touching the forehead and lips to make a preliminary judgment of the elevated intraocular pressure. Self-assessment, the patient should first close the eyes, and then gently touch the eyeballs with the index fingers of both hands across the upper eyelid, the hardness of the eyeballs when touched under normal intraocular pressure is similar to touching the tip of the nose, when the intraocular pressure rises, you will feel the hardness of the eyeballs increase, touching the hardness of the forehead, and the intraocular pressure, if it appears to be decreasing, the eyeballs will be softened, and touching the hardness is similar to the lips. Patients can make a preliminary judgment by self-testing in this way. It should be noted that this is only a reference, and can not accurately obtain the degree of elevated intraocular pressure, you need to go to the ophthalmology department of the hospital for intraocular pressure measurement in order to obtain a more accurate value.
