To analyze static characteristics and dynamic functionality of retinal vessels in eyes with central serous retinopathy (CSC) by means of Dynamic Vessel Analyzer (DVA).
Patients presenting with CSC and normal subjects (controls) matched for age and sex between May 2015 and November 2015 were enrolled in the study. Participants underwent complete ophthalmologic examination, including optical coherence tomography, dynamic and static retinal vessels analysis.
A total of 28 eyes of 28 subjects (14 eyes for each group) were included in the analysis. Dynamic analysis during stimulation by flickering light showed mean venous dilation of 3.1±1.6% in CSC patients and 5.3±2.6% in healthy eyes (p=0.005); mean arterial dilation was 3.2±2.5% and 4.1±1.53%, respectively (p=0.28). Static retinal analysis in CSC patients showed a mean Central Retinal Artery Equivalent (CRAE) of 191±19, a mean Central Retinal Vein Equivalent (CRVE) of 216±18 and a mean arteriovenous ratio (AVR) of 0.88± 0.08. In control subjects mean CRAE was 189±16 and mean CRVE 212±19 (p= 0.887 and p=0.65 respectively vs respective measurements in CSC) and mean AVR was 0.89±0.04 (p=0.695). Choroidal thickness was 451±79 µm in CSC eyes, significantly increased compared to control subjects (301±72, p<0.001).
Dynamic analysis revealed a reduced retinal venous dilation in response to flicker light stimulation in CSC eyes. The impaired retinal vascular function together with the increased choroidal thickness may help understanding CSC and give insights in its pathogenesis.
