Abstract

Accurate assessment of extraocular muscle dimensions is crucial for diagnosing orbital and systemic pathologies. Computed Tomography (CT) offers high-resolution imaging for precise measurement of orbital structures. This study aims to establish normative values for the diameters of extraocular muscles in a healthy population using CT imaging and to evaluate variations based on age, gender, and laterality. A prospective analysis was conducted on CT head scans of 118 individuals without orbital pathology. Measurements included diameters of the medial, lateral, inferior rectus, and superior muscle groups for both eyes. The study establishes normative CT-based ocular muscle dimensions, providing a reference for clinical assessment in the Indian population.
