Long term follow-up of persistent choroidal folds and hyperopic shift after complete removal of a retrobulbar mass

BACKGROUND: Hyperopic shift and chorioretinal folds are common findings with intraorbital masses compressing the posterior pole of the globe. These signs usually regress after complete tumour excision. To the best of our knowledge this is the first reported case, where optical coherence tomography was used to document persistent chorioretinal folds after complete excision of a retrobulbar mass. CASE PRESENTATION: A 47-year-old Caucasian woman was referred to our department with long-documented hyperopic shift and gradually decreasing vision in her left eye. Optical coherence tomography showed chorioretinal folds. Magnetic resonance imaging revealed a retrobulbar mass which caused flattening of the posterior pole of the globe. The tumour was successfully removed, and was confirmed to be a cavernous haemangioma on histological assessment. 3 years after surgery the patient still has a similar amount of hyperopia and chorioretinal folds. CONCLUSION: Choroidal folds and hyperopic shift may persist after complete tumour removal. Long term follow-up is advised to rule out recurrence of the intraorbital mass.
