Abstract

Purpose : Comparison of the pharmacologic mydriasis diameters, mydriasis diameters under various illumination circumstances between the eyes with branch retinal vein occlusion(BRVO) and healthy eyes.

Methods : Our study includes 30 patients diagnosed with BRVO that admitted with vision declining for the last 6 months without any treatment.The eyes with BRVO are received as study group and the other healthy eyes are considered to be control group,ie. the study includes 60 eyes.The findings were evaluated by performing biomicroscopic and fundus examination and the best corrected visual acuity(BCVA) was measured.Initially scotopic and soon after mesopic and photopic pupil diameters(PD) were measured after waiting in a dark room for at least 15 minutes(min) before pupil dilatation with Sirius device (CSO; Sirius,Florence,Italy) that analyses anterior segment with combination of scheimpflug camera and placido disc technique.Then, 0.5 % tropicamid and 2.5 % phenylephrine hydrochlorid were dropped in 2 sessions with an interval of 15 min,the mydriatic PD of both eyes were measured with Sirius device after waiting for 45 min.The results of both groups have been compared and analyzed using SPSS Statistics 22.0 program.

Results : 15 patients(50 %) were male, mean age was 59,06(±12,09) years.The region of the occlusion was superior temporal vein for 17 patients (56,67%) and inferior temporal vein branch region for 13(43.33 %).Mean VA for the control group according to logMAR chart was 0,11±0,24 and 0,33±0,44 for the study group(p=0).Statistical analysis of the scotopic PD have revealed no statistical significance between study group(4,87±0,98mm) and control group(4,47±0,98mm).Analysis of the mesopic PD have also revealed no statistical significance between the study group (3,76±0,90mm) and 67 control group (4,08±0,88mm). Analysis of photopic PD has also showed no statistical significance between the study group (3,27±0,72mm) and the control group (3,06±0,40mm). Mydriatic pupil diameter has also been measured with Sirius device for both groups. Mean PD for the study group was 7,87±0,7mm and 7,76±0,68mm for the control group with no statistical significance.

Conclusions : Comparison of the pharmacologic mydriasis diameters and mydriasis diameters under various illumination circumstances between the eyes with BRVO and healty eyes have revealed no statistical significant difference. Branch retinal vein occlusion does not cause changes in pupil diameters.
