Purpose: To analyze the IOP in different positions in exfoliation syndrome glaucoma (GXFS) and to compare them with primary open-angle glaucoma (POAG) patients and normal subjects without glaucoma (normals). Methods: 3 groups of 10 patients each were evaluated. IOP was measured in a seating position, after 30 minutes in a supine position, and after 30 minutes in a prone position. There were no differences in age among the groups. IOP was measured with a Perkins tonometer. All patients with glaucoma were under different treatments, excluding pilocarpine. Results: Mean IOP (+ Standard Deviation) was 10 (2.36), 10.6 (2.08) and 9.95 (1.8) mmHg for the seating, supine and prone positions in the normal group. In the POAG group the values were 13.7 (2.9), 13.7 (2.9) and 13.8 (2.8) mmHg for the seating, supine and prone positions. In the GXFS group the values were 15.7 (2.3), 16.6 (3.4) and 21.2 (2.9) mmHg for the same positions. The increase in IOP when changing to prone position was statistically significant in the GXFS group (p< .001). Range of IOP variation was 0-2 in the normal group, 0-3 in the POAG group and 3-9 mmHg in the GXFS group when changing to prone position. Range of IOP variation was 0-2 in the normal group, 0-2 in POAG, and 0-6 mmHg in GXFS when changing to supine position. Conclusions: There is an important variation in the IOP in patients with GXFS when changing positions. These results should be considered when examining and treating patients with GXFS.
