BMI was classified based on the US age\u2010 and sex\u2010matched percentiles. Unilateral or bilateral VI was classified as best\u2010corrected visual acuity (BCVA) worse than 6\/9 in either or both eyes, respectively.

Compared with high\u2010normal BMI (50th to 85th percentile), adjusted odds ratios (ORs) for unilateral and bilateral VI gradually increased with higher BMI, reaching 1.33 (1.13\u20131.55) and 1.80 (1.37\u20132.35) in men with severe obesity, and 1.51 (1.24\u20131.84) and 1.52 (1.08\u20132.14) in women with severe obesity, respectively. Men with underweight also had increased ORs for unilateral and bilateral VI (1.23; 1.14\u20131.33 and 1.59; 1.37\u20131.84, respectively), a pattern not observed in women (0.96; 0.86\u20131.07 and 1.02; 0.83\u20131.25, respectively).
