Biometric risk factors for central serous chorioretinopathy

Abstract

Aims/Purpose: The goal of the present study was to find the biometric parameters associated with the incidence of CSCR.Methods: The study included 66 eyes of 60 consecutive patients that were diagnosed with acute or chronic CSCR between 01.01.2021 and 30.06.2021. Six patients had a binocular disease. All patients had axial length and retinal parameters measured with the spectral domain optical coherence tomography (SD‐OCT) as well as refraction error tested after cycloplegia. Results of the affected eyes were compared with the healthy fellow eyes (39 eyes) and control group (75 eyes) and correlated to the duration of the disease.Results: No significant differences were revealed between axial length of the affected eyes, healthy fellow eyes and controls (23.31 ± 1.06 vs. 23.59 ± 1.20 vs. 23.33 ± 1.19). Distribution of refraction errors was similar in the three analysed groups. Hypermetropic shift was noted in the affected eyes versus controls (p = 0.030); however, no difference was noted in the refraction error between the healthy fellow CSCR eyes and controls (p = 0.418). Both acute and chronic CSCR cases, as well as their fellow eyes, demonstrated significantly greater choroidal thickness compared to healthy individuals (p < 0.001). Longer disease duration was correlated with significant deficit in macular volume and average central retinal thickness (p < 0.05).Conclusions: CSCR is a clinical entity that can occur in patients with every type of refraction error. Shorter axial length of the eyeball is not associated with higher prevalence of CSCR, however increased choroidal thickness is typical of that entity. Longer disease duration is correlated to the loss of retinal thickness and volume.
