ABSTRACT
Glucose is the primary source of energy for the body’s metabolism. Accommodation lag refers to the slightly less accommodation level to a target by an individual. This study was carried out to determine the effect of glucose on the accommodation lag of young adults. This study was a clinical and case control study carried out at the Department of Optometry Teaching Clinic, Federal University of Technology, Owerri, Imo state, Nigeria. An informed consent was gotten from all the subjects who were part of the study. Case history, visual acuity, external eye examination, ophthalmoscopy, static retinoscopy and glucometry were clinical tests performed on the subjects. The baseline accommodation lag of the subjects was first measured by taking the difference of the static and dynamic retinoscopic finding. Then,12.5g and 19g of glucose powder was administered orally to the female and male subjects respectively in consideration of body weight. The accommodation lag values of the subjects were measured again after 30, 60 and 90 minutes of glucose administration. Results showed that for the female subjects, the mean accommodation lag before glucose intake was 0.58±0.38 D. It became 0.91±0.40 D, 0.81±0.51 D and 0.69±0.48 D after 30, 60 and 90 minutes of glucose intake respectively. For the male subjects, the mean accommodation lag before glucose intake was 0.61±0.08 D. It became 0.73±0.15 D, 0.73±0.25 D and 0.63±0.11 D after 30, 60 and 90 minutes of glucose intake respectively.SPSS data analysis using the one-way ANOVA at 0.05 level of significance showed that there was a significant difference (P< 0.05) in accommodation lag before and after 30, 60 and 90 minutes of glucose intake.Eye care practitioners were advised to monitor the blood glucose values of their patients especially when there are sudden changes in their accommodative functions.
