Abstract Details


To examine the relationship between choroidal thickness (CT) and renal function tests.


Retina Unit, Ophthalmology Department, Virgin Macarena University Hospital (Seville, Spain). RETICS OftaRed, Institute of Health Carlos III (Madrid, Spain). Diabetes Unit, Endocrinology and Nutrition Department, Virgin Macarena University Hospital (Seville, Spain).


Cross-sectional study with 42 eyes of 21 ocular treatment-naïve diabetic patients. Demographic and ocular data were analyzed as well as the following renal function tests: microalbuminuria, microalbumin/creatinine ratio and glomerular filtration rate (CKD-EPI and MDRD-4). Choroidal thickness was measured by swept-source ocular coherence tomography (SS OCT).


The mean age was 49,76 ± 17,61 years old (18-74), with a sex ratio of approximately 1:1. 66.7% suffered from type 2 diabetes mellitus, with a mean time of evolution of 12,14 ± 10,08 years. 51.2% of patients didn’t present diabetic retinopathy. Among renal function tests, only microalbuminuria positively correlated with CT (p<0,05).


The analysis of CT with SS OCT could be a prediction tool of renal function in diabetic patients.
