OBJECTIVE:To assess relationship between body mass index (BMI) and intraocular pressure (IOP) after adjusting for risk factors.METHODS:This prospective study was conducted in 500 subjects aged 20-80 years.BMI was expressed as kg/m2. IOP was measured in sitting and supine positions by Tono-Pen.After adjusting for risk factors for increased IOP (age, mean arterial blood pressure and central corneal thickness, stepwise regression analyses was done.RESULTS: Mean ± SD age was 49.3 ± 9.6 years, 66% were men.Positive linear correlation was found between BMI and IOP in supine position in men (r=0.152, p= 0.003) and women (r=0.219, p=0.007).However, the relation between BMI and IOP in sitting position was not significant in both men and women.CONCLUSION: No significant correlation was found between IOP and BMI in sitting position.Supine IOP was statistically correlated with higher BMI.This could be due to compression on chest wall by body fat translating into increased central venous pressure.
