AIM: To investigate the effects of body mass index (BMI) on intraocular pressure (IOP) and ocular pulse amplitude (OPA).
AIM: To investigate the effects of body mass index (BMI)
on intraocular pressure (IOP) and ocular pulse amplitude
METHODS: Totally 140 healthy individuals without any
systemic diseases were included in the study. BMI (kg/m2)
was calculated for every individual. IOP and OPA were
measured with Pascal Dynamic contour tonometer (DCT).
Blood pressure was also measured along with the DCT. The
patients were divided into three groups according to BMI as:
Group1, BMI<25; Group2, 25≤ BMI<30; Group3, BMI≥ 30.
Mean values of IOP, OPA, systolic blood pressure (SBP) and
diastolic blood pressure (DBP) were used in statistical
RESULTS: In Group1, the means of IOP, OPA, were 16.8±
2.3mmHg, 2.7± 0.7mmHg respectively; and SBP, DBP were
120.0 ± 6.1mmHg, and 77.4 ± 5.6mmHg respectively. In
group2, the mean IOP, OPA, SBP, and DBP were found to be
16.6 ± 2.1mmHg, 2.4 ± 0.7mmHg, 121.7 ± 5.3mmHg, and
79.5 ± 4.9mmHg respectively. In group3, the mean IOP,
OPA, SBP, and DBP were found to be 17.3 ± 1.7mmHg,
2.1 ± 0.7mmHg, 122.4 ± 5.7mmHg, and 79.7 ± 5.2mmHg
respectively. There were no statistically significant difference
between groups in terms of IOP, SBP and DBP, while OPA
values were significantly lower in group3( =0.001).
CONCLUSION: Decreased OPA values in individuals with
higher BMI may indicate that subjects with higher BMI have
lower choroidal perfusion and lower ocular blood flow.
