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