Abstract :
Introduction: To compare various accommodative parameters in peri-presbyopic diabetic patients with
age-matched healthy individuals.
Aim: To compare Four Accommodative parameters in peri-presbyopic early onset diabetic patients and
age matched non-diabetic individuals.
Objectives: 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.
Materials and Methods: Study setting – peri-presbyopic symptomatic patients attending the
Ophthalmology outpatient department, from August 2016- December 2016. This cross-sectional casecontrol
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.
Results: 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
Mean positive RA, Mean negative RA and Mean NPC did not reach statistical significance.
Conclusion: 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.
