Foveal serous detachment and its association with body mass index and severity in diabetic retinopathy

Abstract

To determine the prevalence of foveal serous retinal detachment in diabetic macular edema among Indians, establish the affiliation between serous retinal detachment (SRD) and severity of diabetic retinopathy, to study its association with the body mass index (BMI) and demographic profile of these patients. Retrospective single-center analysis was done of all patients with diabetic macular edema at the retina clinic between December 2016 to October 2017. The overall prevalence of serous retinal detachment in diabetic retinopathy was 46.5%. The average central macular thickness (CMT) of patients having sub foveal SRD was 584.6 microns. Statistically, significantly higher mean was found in patients with Proliferative diabetic retinopathy (PDR) having SRD (p-value 0.017) over those with Non-Proliferative diabetic retinopathy (NPDR). A higher prevalence of SRD was noted among men (p-value 0.035) and with patients with higher BMI (p-value 0.0028). Higher prevalence of serous retinal detachment (SRD) was seen in proliferative diabetic retinopathy with a higher prevalence among the Indian population with male predilection and among patients with higher BMI.
