Abstract

Purpose: A community-based study was conducted to identify the extent of prevalence of refractive errors among the type 2 diabetic population in Lucknow. 

Methods: A total of 437 patients (> 40 years old) with type 2 diabetes were examined with a complete eye screening tests including objective auto refraction. Spherical equivalent refractions of both eyes were reported. Data collected include age, gender, general medical information and serum biochemistry. 

Results: The mean refraction was −0.84 ± 2.59 D. Prevalence rates were determined for astigmatism (63.8%) hyperopia (1.4%) and myopia (0.2%%). 34.6% patients were emmatropic. Age is an important factor for all of the refractive errors. Correlation showed that every increase of one year of age and one percent of HbA1c is associated with 0.05 D (p = 0.003) and 0.14D (p = 0.04) shift in hyperopia, respectively.

Conclusions: This study provides epidemiological data on refractive errors in a North indian population in Lucknow, India. The Astigmatism prevalence is higher than the reported rates in the diabetic population compare to hyperopia and myopia. Second major finding was emmatropia.
