A Space-Occupying Lesion Manifesting as Unilateral Optic Disc Edema

Background: Primary and secondary orbital diseases can arise from different tissues in the periorbital regions as space-occupying lesion leading to ophthalmic symptoms. Therefore, eye care providers are often the first encounter for these patients. Case report: A 54-year-old Caucasian male presented as a new patient at the eye clinic with an incidental f inding of edema of the left optic disc. After a thorough optometric evaluation, a referral was made to a local ear-nose-throat (ENT) specialist who confirmed a diagnosis of cavernous hemangioma by further neuroimaging. Surgical removal eventuated in resolution of disc edema with restoration of vision. Conclusion: An insidious and asymptomatic cavernous hemangioma can lead to irreversible vision loss and require surgical excision. Comprehensive ophthalmic examination and multimodal imaging are essential in early detection and timely management. A health care team consisting of an ENT surgeon, neuroradiologist and optometrist was necessary to manage this orbital space-occupying lesion successfully.
