Purpose: to report annular choroidal detachment one year after Argus-II retinal prosthesis implantation. Patient: A 63-year-old male patient who had a history of Argus-II retinal implantation surgery in his left eye a year ago, referred to the clinic complaining of two weeks left eye irritation, redness, and mild pain. Result: On physical examination, the intraocular pressure (IOP) was 5 mmHg (hypotonia) and his visual acuity with the system on had no change compared to the previous examination. Rubeotic vessels were seen on iris especially around the papillary margin. On B-scan sonography annular choroidal detachment was seen, so the patient underwent 23 gauge vitrectomy and silicon oil was injected.Conclusion: This is the first report on annular spontaneous choroidal detachment after Argus-II retinal prosthesis.
