Abstract

Purpose: To compare central retinal venous pressure (CRVP) among eyes with and without optic disc hemorrhage (ODH) in bilateral open-angle glaucoma (OAG) patients and OAG eyes without an<br /> episode of ODH.

Methods: In this prospective study, we included 22 bilateral OAG patients showing a unilateral ODH and 29 bilateral OAG patients without an episode of ODH. Eyes were categorized into group A (n = 22, eyes with ODH), group B (n = 22, fellow eyes without ODH), and group C (n = 29, OAG eyes without an episode of ODH). A contact lens ophthalmodynamometer was used to measure CRVP and central retinal arterial pressure (CRAP).

Results: Intraocular pressure (IOP) measured on the day of contact lens ophthalmodynamometry showed no difference among groups. The lowest baseline diurnal IOP in group A was significantly lower than that in group C (P = .009), as was the highest baseline diurnal IOP (P = .011). The CRVP in group A (29.1 ± 10.8 mmHg) was significantly lower than that in group C (40.1 ± 8.8 mmHg; P = .001), but similar to that in group B (30.5 ± 8.7 mmHg; P = .409). A similar relationship was noted for CRAP. Generalized estimating equation model revealed that neither CRVP nor CRAP was associated with ODH.

Conclusions: CRVP was lower in OAG eyes with ODH than in eyes without an episode of ODH, but similar to that of fellow eyes without ODH. These imply that increased central retinal venous resistance may not be associated with ODH.
