PURPOSE: Study purpose was to investigate the effects of bariatric surgery on intraocular pressure (IOP) and other ophthalmic parameters in a prospective observational follow-up study. METHODS: Ophthalmic examination was performed on 22 obese women before and 6 months after bariatric surgery. A control group of 15 non-obese age-matched women were studied twice 6 months apart. IOP was measured with the Goldmann applanation tonometer (GAT) and the Pascal dynamic contour tonometer (PDCT). None of the subjects had glaucoma. RESULTS: Average weight loss 6 months after bariatric surgery was 25 ±8 kg, (p < 0.05). Visual acuity (VA), pachymetry and systolic as well as diastolic blood pressures did not differ between the obese and control groups and no change between the visits was detected. At baseline, IOP was significantly higher in the obese group than in the controls (16.6 ± 3.0 mmHg GAT and 18.1 ± 2.2 mmHg PDCT compared with 14.3 ± 1.5 mmHg GAT and 16.5 ± 1.9 mmHg PDCT respectively). After bariatric surgery, IOP was significantly lower (15.2 ± 2.7 mmHg GAT and 16.5 ± 2.0 mmHg PDCT, p < 0.05) and no significant difference was detected between the operated and control groups. In the whole data at baseline, IOP correlated with weight, body mass index, waist circumference, body fat per cent and systolic blood pressure values. CONCLUSION: Intraocular pressure (IOP) is significantly higher in obese women than in non-obese age-matched controls. Obese subjects had a decrease in IOP after bariatric surgery with no change in IOP in the control group. This change in obese group may be related to weight loss. Different measures of obesity correlated with IOP at baseline.
