The Convex Retina: Optical Coherence Tomography in Hypermetropic Shift, Without Choroidal Folds, from Intraconal Cavernous Haemangioma

A 36-year-old female referred with improving unaided vision in her left myopic eye was found to have a left 4.5 diopter hypermetropic shift. Examination revealed a left 2 mm proptosis but was otherwise normal with no choroidal folds on fundoscopy and bilateral 6/5 corrected vision. Her visual field and B scan image were also unremarkable. Optical Coherence Tomography (OCT) imaging demonstrated left-sided anterior retinal bowing with a convex retinal appearance. Magnetic Resonance Imaging (MRI) confirmed a well-circumscribed intraconal mass. The intraconal mass was successfully removed via lateral orbitotomy and confirmed as a cavernous haemangioma on histological assessment. We document these OCT findings and review published ultrasound detected scleral deformation from similar retro-orbital mass cases.
