Abstract: (146 Views)
Background and Objectives: The body mass index (BMI), which is used to assess obesity and underweight, has garnered significant scientific interest due to the widespread occurrence of overweight and its convenient measurement. Lately, research is conducted on studying the correlation between this index and other eye characteristics. Nevertheless, despite the significant importance of accommodation performance in terms of visual quality, a thorough investigation of the correlation between BMI and accommodation performance has not yet been conducted. This research aims to determine the impact of obesity and underweight on the performance of ocular accommodation.
Methods: Descriptive-analytical research was conducted in Tehran Province, Iran, including the evaluation of 168 people aged 18 to 30 years. The assessment included measurements of refraction, amplitude of accommodation, facility of accommodation, and lag of accommodation. Furthermore, height, weight, and BMI were measured.
Results: The study revealed a positive correlation between a decline in BMI and an increase in the lag of accommodation. Nevertheless, no significant relationship was observed between the facility of accommodation (P=0.35) and the amplitude of accommodation with BMI (P=0.43). The linear regression analysis revealed a significant correlation between lag of accommodation and weight, with an inverse relationship between BMI and lag of accommodation (P=0.04).
Conclusion: In contrast to several other systemic and ocular disorders that are negatively impacted by a higher BMI, this research revealed that individuals with a lower BMI have diminished adaptive ability, particularly regarding accuracy in responding. Various potential causes have been considered. Greater emphasis should be placed on accommodation tests, particularly for underweight people.
