Giant Conjunctival Cyst of the Orbit in a Patient with Previous Enucleation

Abstract

Introduction: Conjunctival cysts of the orbit development are a rare complication in enucleated patients. They result from the entrapment of conjunctival epithelium within the orbit. Case Presentation: We report the case of a 25-year-old man with a history of enucleation for a retinoblastoma of the right eye who presented with difficulty in fitting his eye prothesis. On his past medical records, there was no reference to the placement of any orbital implant at the time of the surgery. Biomicroscopy of the right eye revealed a thickened bulbar conjunctiva, an inferior symblepharon, and a translucid central area with vascularization. Imaging was remarkable for a cystic cavity filling the whole right orbit. Biopsy revealed the diagnosis of a conjunctival cyst, and drainage was performed, alleviating the patient’s symptoms. Conclusion: Orbital conjunctival cysts may pose a clinical problem, and treatment modalities include surgical excision, absolute alcohol injection, and trichloroacetic acid injection.
