Abstract

Purpose To review the incidence and features of vitreoretinal complications of a permanent Boston keratoprosthesis and to report the use and outcomes of 23-gauge vitrectomy to manage vitreoretinal pathology. Design Retrospective non-comparative, interventional case series. Subject, Participants 27 eyes of 27 patients managed with a Boston keratoprosthesis at Moorfields Eye Hospital over a 3-year period. Methods All eyes that underwent pars plana vitrectomy (PPV) and had at least 6months follow-up were analysed with a specific focus on the anatomical and histological characteristics of retinal detachment and outcomes of surgery. Main outcome measures Anatomical success and characteristics of retinal detachment over the follow-up period. Results 27 patients underwent Boston keratoprosthesis implantation over the study period. Of these, six (22%) required PPV for retinal detachment which demonstrated a specific pattern of serous elevation with subsequent severe anterior proliferative vitreoretinopathy (PVR). The mean follow-up period was 9months (range 6-14 months). At final follow-up, visual acuity ranged from perception of light to 6/18, and five of six cases had attached retinae under the silicone oil. Histological analysis of a subretinal membrane demonstrated a predominantly glial/retinal pigment epithelium fibrocellular tissue, consistent with PVR. Conclusions The study showed that retinal detachment complicated by PVR, as demonstrated by the clinical and histological characteristics of this condition, is common in patients undergoing Boston keratoprosthesis. We also showed that 23-gauge vitrectomy can be effectively performed in patients with a permanent prosthesis. Visual acuity often remains poor, despite successful anatomical results.
