Aims and Objectives The aim was to determine CT measured ocular biometry in Mid-Western Nigeria which may be employed on other Nigerians and Black Africans. Patients and Methods The ocular images of 200 patients that had normal cranial CT scans without ocular abnormality or complaints were retrospectively retrieved and analysed. The CT scans were done at the University of Benin Teaching Hospital. The axial length and width were obtained at the maximum mid-axial images and analysed using SPSS version 17 for measures of central tendency and correlations between variables (level of significance set at 0.05). Results The mean axial length was 21.4mm (right) and 21.6mm (left) while the width was 21.6mm (for right and left). The ocular biometry was larger in the left eye than the right, and also in males than females. The axial length and width increased with advancing age. ConclusionCT ocular biometry can be performed on previous cranial CT scans done for other reasons. The dimensions in this study may be used as a local normogram.
