Official Title: Evaluation of the Effects of Anterior Clinoid Process Pneumatization on Optic Canal Morphometry and Retinal Nerve Fiber Layer Thickness Using Computed Tomography and Optical Coherence Tomography: A Re

Brief Summary: This retrospective cohort study aims to evaluate the potential effects of anterior clinoid process (ACP) pneumatization on optic canal morphometry and retinal nerve fiber layer (RNFL) thickness.ACP pneumatization is an anatomical variation that may alter the morphology of the optic canal and potentially influence the optic nerve.Patients aged 18-65 years with available head and neck computed tomography (CT) imaging and optical coherence tomography (OCT) examinations between August 2018 and July 2025 will be…
