[Influence of ethnic and eye condition on ultrasound A in ophthalmology at UHNC-HKM of Cotonou].

PURPOSE

To study impact of sociocultural groups and ocular condition on biometric data at University and Hospital National Center of Cotonou

PATIENTS AND METHODS

We conducted a descriptive cross-sectional study from 1st January to March 31, 2009 in the eye clinic at CNHU-HKM of Cotonou. It involved 116 patients aged over 16 years and Beninese nationality.

RESULTS

The mean age was 48 years ± 15.7. The sex ratio was 0.78. The "fon" socio-cultural's group was the largest with 43.96%. The eye condition was normal in 79 cases (68.10%). Primary glaucoma with open angle (OAPG) and cataract were observed in respectively 18.10% and 13.79%. Biometrics eye was not influenced by the socio-cultural groups, or by the OAPG. In contrast, cataract induced increase in the lens's thickness and reducing the depth of anterior chamber.

CONCLUSION

The lens plays a key role in changing the biometrics of the anterior segment.
