PURPUSE: To determine the correlation between presbyopia and body mass index. METHODS: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive test cover, anisometropy with convergence insufficiency or high correlation convergence / accommodation. Assessment of body mass index of all patients, RESULTS: Cross-sectional study involving 1030 patients with visual acuity of 20/20 emmetropy, aged between 36-40 years, 51-55 years and 60-65 years, excluding patients with positive cover test, anisometropy with convergence insufficiency or high correlation convergence / accommodation. Assessment of body mass index of all patients CONCLUSION: As demonstrated by statistical analysis there is a significant correlation between low body weight defined as a body mass index below 18.5 and a lower incidence of presbyopia or delay its onset and progression with age.
