Abstract

Aim: To compare the posture-induced variations in IOP between the glaucomatous and non-glaucomatous eyes. Methods: A case-controlled age matched study was conducted in 30 successive newly diagnosed POAG and 30 normal patients seen in OPD in a tertiary care hospital in Maharashtra The IOPs of eligible correspondents were measured with Perkin's tonometer in sitting, supine flat and supine with pillow positions respectively. Measurement of IOP in each position was done after 15min of assuming such posture.
Results: The IOP difference between the sitting and supine flat position was significantly higher in the POAG than non-glaucoma subjects (7.68±2.08 vs 4.03±0.13 mm Hg, P<0.001). The IOP difference between the sitting and supine with pillow positions was 2.61±1.49 mm Hg for POAG and 1.44±0.70 mm Hg in non-glaucoma (P<0.001), while difference between supine flat and supine with pillow positions was 5.07±2.24 mm Hg in POAG and 2.59±0.66 mm Hg in non-glaucomatous patients (P<0.001).
