The aim of the study reported here was to assess the influence of serum HbA1c levels on foveal choroidal thickness in diabetic patients.

A total of 122 eyes from 122 patients who had type 2 DM were studied in this prospective, cross-sectional study. Patients were divided into three groups: 43 patients (43 eyes) without diabetic retinopathy (NDR), 39 patients (39 eyes) with diabetic retinopathy and no macular edema (DR/ME-), 40 patients (40 eyes) with diabetic retinopathy and macular edema (DR/ME+). Subfoveal choroidal thickness measurement was performed perpendicularly from the outer part of the retinal pigment epithelial layer to the line corresponding to the choroidal-scleral junction. Serum glycosylated haemoglobin (HbA1c) levels were evaluated.
No significant differences in age, gender, pseudophakia were observed between the groups. There was no significant difference in HbA1c value among the three diabetic groups. Mean foveal choroidal thickness in NDR group was significantly different from DR/ME- group. There was no statistically significant difference between the other groups among foveal choroidal thicknesses. There was no correlation between HbA1c and foveal choroidal thickness.
Serum HbA1c levels were not correlated with foveal choroidal thickness. Choroidal thickness is effected by several factors as axial length, age and systemic diseases.
