Abstract
In 44 normal, 15 controlled glaucomatous and 8 uncontrolled glaucomtous eyes, the influence of body positin on the intraocular pressure was studied using Perkins applanation tonometer. The pressure increment when changing from the seated to supine positin averaged 2.7 mm Hg in normal eyes. 2.1 mmHg in controlled glaucomatous eyes and 3.7 mmHg in the uncon trolled glaucomatous eyes. Pressure increment in each group was highly significant. The increased pressure was reversible when returning to the original seated position. It appears that the clinically important pressure to be considered in the diagnosis and management is the supine pressure in addition to the seated pressure.
