PRCIS: Transscleral diode laser cyclophotocoagulation may trigger the development of proliferative vitreoretinopathy. Our article demonstrates one such case leading to tractional macula-off retinal detachment in a child with aphakic glaucoma. PURPOSE: The purpose of this article is to describe a case of proliferative vitreoretinopathy (PVR) developing subsequent to transscleral diode laser cyclophotocoagulation (cyclodiode) in a pediatric patient with aphakic glaucoma. PVR most commonly occurs following rhegmatogenous retinal detachment repair; however, to the best of our knowledge, it has never been reported to appear after cyclodiode. METHODS: Retrospective evaluation of case presentation and intraoperative findings. RESULTS: A 13-year-old girl with aphakic glaucoma presented 4 months after cyclodiode of the right eye with a retrolental fibrovascular membrane and anterior PVR. The PVR extended posteriorly over the next month, after which the patient developed a tractional macula-off retinal detachment. Pars Plana vitrectomy was performed, confirming dense anterior and posterior PVR. A review of the literature suggests that an inflammatory cascade, similar to that seen in PVR development following rhegmatogenous retinal detachment, may occur from the destruction of the ciliary body by cyclodiode. As a result, fibrous transformation may occur, likely accounting for the cause of PVR development in this case. CONCLUSION: The pathophysiology of PVR development remains unclear. This case demonstrates that PVR may occur following cyclodiode and should be considered during postoperative monitoring after this procedure.
