To establish possible relationship between wavefront (WF) aberrations, pupillary function and obesity in children.
Fifty-eight obese children (body mass index in the 95th percentile or greater) were compared with 58 age and sex-matched controls (body mass index <95th percentile) in this prospective study. WF aberrations, photopic and mesopic pupil sizes were measured using OPD-Scan II Pupillometer/Corneal WF Analyser ARK-10000 system (Nidek, Japan). The differences between groups were analyzed by Mann Whitney U- Test.
Photopic pupil size in obese children was significantly lower than control group (3,63±0.64, 4,83±0.63 mm; p<0,001 respectively). Mesopic pupil size in obese children was higher than control group but it was not significant (6,83±0.60, 6.65±0.77 mm; p>0.05 respectively). Total optical aberrations of eyes were also significantly higher in obese children (1.53±1.51, 0.88±0.47; p<0.01). All other aberrations including coma, trefoil, tetrafoil and total high order aberrations were higher in obesity group but these differences were not statisticly significant (p>0.05).
This study showed an association between total WF aberrations, pupillary function and obesity. Although the difference between groups was not statistically significant, WF aberrations alterations in obese children might have been effected by increase in mesopic pupillary diameter. These data suggest that obesity might be an important risk factor for aberration associated diminished optical quality in children.
