Dear Editor,
Thank you for your interest in our article.[1]
We would like to make the following clarifications.
First, the study was carried out over a 6-month period from November 2018 to April 2019. Hence, it was before the outbreak of the coronavirus pandemic.
Second, the criteria for normal controls were based on fasting blood sugar level of <110 mg/dl and HbA1c of <6 g %.
Finally, patients of severe nonproliferative diabetic retinopathy and proliferative diabetic retinopathy were intentionally not included. The aim of this study was to evaluate changes in the peripapillary retinal nerve fiber layer thickness in diabetic patients with no diabetic retinopathy and early diabetic retinopathy and to co-relate it with glycemic control. Moreover, patients of proliferative diabetic retinopathy require laser treatment which itself causes retinal nerve fiber layer thinning.[2] This would have been a confounding factor in the study.
Only patients of type 2 diabetes mellitus were included in the study as we wanted to study the co-relation between peripapillary retinal nerve fiber layer thickness and glycemic control in type 2 diabetes mellitus only.
