Relationship between intraocular pressure and body mass index

To determine the relationship of intraocular pressure [IOP] with body mass index [BMI]. A cross-sectional comparative study. Armed Forces Institute of Ophthalmology, Rawalpindi, from February 2010 to July 2010. Three hundred subjects meeting inclusion and exclusion criteria were enrolled. IOP was recorded. Height and weight were measured and BMI was calculated. IOP showed positive relationship with BMI. A BMI change by 1 kg/m[2] corresponded with a change in IOP by 0.23 mmHg [p<0.01] in males and 0.14 mmHg [p=0.004] in females. A positive relationship was found between IOP and BMI in both genders
