ELEVATION OF INTRAOCULAR PRESSURE (IOP) IN PATIENTS WITH ASYMMETRIC PRIMARY OPEN -ANGLE GLAUCOMA (POAG) IS ASSOCIATED WITH THEIR PREFERRED SLEEPING POSITION

Purpose: To evaluate the changes in IOP in patients with asymmetric glaucoma when lying on their preferred sleeping position. Methods: 3 groups of 10 patients each were evaluated. Group A was asymmetric POAG, B was symmetric POAG, and C was formed by normal subjects without glaucoma. Asymmetric POAG was defined as a difference in IOP > 3 mmHg as measured in at least 3 occasions, and/or asymmetric cup to disc ratio,
