The effect of change of posture on the level of the intraocular pressure was studied in 22 patients who had suffered 'occlusion' of a central retinal vein, 14 patients with occlusion of a tributary of the central vein, and 23 normal subjects. The results showed a significant difference in behaviour between subjects in the control group and both groups of patients with retinal vein occlusions. I...
