Abstract

Introduction: India has a large number of diabetic patients and there is a steep rise in the incidence of
diabetes in the last decade. Diabetic control is categorized as poor control (HbA1c levels above 7%) and
good control (HbA1c levels below 7%). Critical flicker fusion frequency (CFF) is a non-invasive test, which
could help early detection of retinal dysfunction and optic neuropathic changes in Type 2 diabetes mellitus
(T2DM).
Objective: To compare the CFF between
Group 1: T2DM (HbA1c < 7%).
Group 2: T2DM (HbA1c >7%).
Methodology: Sixty diagnosed T2DM patients were the subjects in this study. Thirty patients had their
HbA1c < 7 g% and 30 >7 g%. The patients were recruited from Medicine department, Rajarajeswari Medical
College and Hospital. CFF was measured using an in-house built apparatus. CFF values were noted and then
analyzed.
Results and Discussion: The mean CFF in group I and the group II patients were 30.17+ 4.69 Hz and
26.32+ 6.70 Hz, respectively. This was highly significant (P = 0.012). The significantly lower CFF in the
poorly controlled group II diabetics can be attributed to poorglycemic control in that group.
