Morphometric evaluation of the ocular globe: A Nigerian retrospective study

Background: The ocular globe morphometry is essential in the screening, diagnosis and management of numerous ophthalmologic pathologies. Aims and Objectives: This study was designed to determine the globe diameters, position and protrusion among adults seen at a radiological unit in Delta State, Nigeria. Material and Methods: Digital brain Computed Tomography (CT) (150) and Magnetic Resonance (MRI) Images (150) archived in a Nigerian Teaching Hospital in Delta State were used to assess the ocular morphometry after seeking institutional approval. Inferential statistical analysis was done and regarded significant at p < 0.05. Results: Both MRI and CT groups, had symmetrical globe diameters while asymmetry was observed in the globe protrusion and the eyeball volume calculated from MRI measurements. The ocular parameters showed significant gender differences and the CT globe diameters had a negative correlation with age. Significant positive associations between the globe diameters, position, protrusion and interzygomatic line were observed. Conclusion: The values of the globe parameters obtained are useful to ophthalmologists and radiologists in the diagnosis, management and follow-up of different ocular conditions in the study region.
