Central retinal artery and vein collapse pressure in eyes with chronic open angle glaucoma

Abstract

Aims: To determine central retinal vessel collapse pressure in chronic open angle glaucoma. Methods: For 19 eyes with chronic open angle glaucoma and 27 eyes of a control group, central retinal vessel collapse pressure was measured by a Goldmann contact lens fitted with apressure sensor in its holding grip. Results: Central retinal vein collapse pressure was significantly (p=0.001) higher in the glaucoma group than in the control group (26.1 (SD 26.4) relative units versus 6.1 (8.4) relative units). Conclusions: Measured by a new ophthalmodynamometer, central retinal vein collapse pressure measurements may be abnormally high in eyes with chronic open angle glaucoma.
