Abstract Details

Purpose:

Ocular pulse amplitude (OPA) was suggested as an indirect indicator of the choroidal perfusion. Our purpose in this study was to assess the OPA in eyes with retinal vein occlusion (RVO) and to compare it with the OPA values in their fellow eyes and the control subjects.

Setting:

Pamukkale University, Department of Ophthalmology, Denizli, Turkey

Methods:

Patients with RVO and age-gender matched healthy patients were included in the study. In the RVO group, 4 patients had central RVO, whereas 26 patients had branch RVO. OPA was measured by dynamic contour tonometry. OPA in eyes with RVO as well as in the fellow eyes were compared to OPA values in the control eyes.

Results:

Thirty patients with RVO and 29 healthy subjects were enrolled in the study. The mean OPA was 2.51±1.13 in eyes with RVO, 2.65±1.21 in the fellow eyes of the patients with RVO and 2.54±1.06 in the control group. The mean OPA in eyes with RVO was not significantly different from that in the fellow eyes or the control eyes (p=0.149 and 0.894 respectively). Similarly, the mean OPA in the fellow eyes was not significantly different from that in the control eyes (p=0.726). The mean OPA did not correlate with age (p=0.267, r=0.209), did not significantly change according to the RVO type (p=0.985) or having a systemic vascular disease (p=0.552).

Conclusions:

OPA in eyes with RVO was not significantly different from that in the fellow eyes and the control eyes. This finding suggests that the choroidal perfusion, which is assessed by OPA, is not compromised in eyes with RVO.
