Normal value Generally, Tn is normal, the intraocular pressure is T+1, 2, and 3, and the intraocular pressure is low at T-1, 2, and 3. Clinical significance Abnormal result T+1, T+2 and T+3 indicate different degrees of intraocular pressure rise with T+3 as the highest; T-1, T-2 and T-3 indicate different degrees of intraocular pressure decrease to T-3 For the lowest. Need to check the crowd's eyes without inflammation can be checked. Precautions Forbidden before examination: emotional. Requirements for inspection: When the eyeball is pressed, the force is not too large. Inspection process 1. The subject is closed and the eye is looking down. 2.
