Phthisis Bulbi in a Retinitis Pigmentosa Patient after Argus II Implantation
Purpose. To report a previously unreported complication of phthisis after Argus II prosthesis implantation in a retinitis pigmentosa (RP) patient. Case. A 61-year-old male with advanced RP presented to the retina clinic. The patient had a history of vitrectomy in both eyes (OU) in Cuba in 1996. Pre-...

| description | Purpose. To report a previously unreported complication of phthisis after Argus II prosthesis implantation in a retinitis pigmentosa (RP) patient. Case. A 61-year-old male with advanced RP presented to the retina clinic. The patient had a history of vitrectomy in both eyes (OU) in Cuba in 1996. Pre-op visual acuity (VA) was no light perception (NLP) in the right eye and light perception (LP) in the left eye. The patient met the criteria for Argus II implantation and elected to proceed with surgery in his left eye in December 2017. The surgical implantation of the Argus II was successful without any complications. On postoperative day 1, his VA was stable at LP. He was satisfied with his ambulatory vision after the electrodes were turned on. Four months after surgery, the patient was complaining of aching pain; he was found to have preseptal cellulitis and was started on antibiotics. This swelling improved over two weeks, but when the patient returned, he had a two mm hyphema associated with mild ocular inflammation without an inciting event or reason on exam. The hyphema was treated and resolved after two weeks. However, one month after the hyphema resolved, at postoperative month six, the patient’s vision in his left eye became NLP and began to demonstrate phthisical changes, including hypotony, Descemet membrane folds, and a vascular posterior capsular membrane. Discussion. The theoretical causes of phthisis bulbi after Argus II implantation include fibrous downgrowth, ciliary shut down due to immune reaction, inflammation, or trauma. While the cause of phthisis in this Argus patient is not certain and possibly multifactorial, it is important to note that phthisis is a possible complication of an Argus II implant, as this patient had no other obvious insult or reason for the phthisical change. |
