This is a case report involving a 56-year-old male patient with a history of pars plana vitrectomy due to a rhegmatogenous retinal detachment in the right eye that resulted in the implantation of a drainage device after the patient developed secondary glaucoma. Two years after the device's implantation, the patient was referred to our care as his visual acuity had decreased to 20/200 (1.00 LogMAR). At the fundus evaluation, a choroidal amelanotic elevation was observed at the upper temporal equator, and a potential diagnosis was made of amelanotic choroidal melanoma. The ultrasound exam visualized the patient's implanted superotemporal justabulbar drainage device, which revealed a transscleral communication from the plate fibrocapsular's draining space to the suprachoroidal space (fistula). The ultrasound also revealed a focal pocket of choroidal detachment in the patient's superotemporal region, simulating an amelanotic choroidal melanoma. A new pars plana vitrectomy was performed to remove the internal limiting membrane without repercussions at the fistula site. The patient's recovery progressed well, and he regained a visual acuity of 20/70 (0.55 LogMAR). To the best of our knowledge, this is the first case report of this condition.
