Accommodative parameter assessment in peri-presbyopic early onset diabetics with age matched healthy individuals - A case control study

Abstract

To compare various accommodative parameters in peri-presbyopic diabetic patients with age-matched healthy individuals.To compare Four Accommodative parameters in peri-presbyopic early onset diabetic patients and age matched non-diabetic individuals.1. To compare and analyse Four accommodative parameters in peri-presbyopic early onset diabetics with that of peri-presbyopic age matched non-diabetic individuals (35-45; years); 2. To analyse the effect of treatment / metabolic control on the parameters. 3. To observe, if any, other systemic association that affects accomodation in both cases and controls.Study setting – peri-presbyopic symptomatic patients attending the Ophthalmology outpatient department, from August 2016- December 2016. This cross-sectional case-control study was performed on 50 young onset peri-presbyopic early onset symptomatic diabetics and 50 age-matched peri-presbyopic, Non-diabetic individuals. Using the best correction for distance visual acuity, multiple accommodative ability tests such as near point of accommodation, accommodative amplitude, negative or positive accommodative facility and near point of convergence were measured in both groups. Statistical analysis made using SPSS version 16 Normality of distribution was checked with Kolmogrov-Smirnov test. Differences in accommodative functions between groups tested using student T test, Man Whitney test and repeated measures of analysis of variances. Level of significance was set at p-values <0.001. Mean NPA, Mean AA and Mean AF were statistically significant (p<0.001).Mean positive RA, Mean negative RA and Mean NPC did not reach statistical significance. Majority of accommodative ability functions are decreased in Peri-presbyopic diabetic patients. Early detection and rehabilitation of such patients with full near vision correction is strongly recommended.
