PURPOSE: To report the outcomes after cataract extraction in eyes previously treated for retinoblastoma.
METHODS: We reviewed the medical records of consecutive patients treated with cataract extraction at our institution for radiation-induced cataract following retinoblastoma treatment between 1992 and 2007.
RESULTS: Twelve eyes of 11 patients were included. The median age at diagnosis of retinoblastoma was 7.4 months. The median quiescent interval before cataract surgery was 34.6 months (range, 17-240 months). All patients underwent limbal-based extracapsular cataract extraction with scleral-tunnel wound construction. Anterior vitrectomy and posterior capsulotomy were performed in 7 eyes; an intraocular lens was placed in 10 eyes. A laser capsulotomy was subsequently performed in 5 eyes. No postoperative complications occurred. One patient underwent a pars plana vitrectomy for vitreous hemorrhage and proliferative retinopathy 5 years after cataract extraction. The median follow-up after surgery was 6.0 years (range, 1.1-12.3 years). Final visual acuity was between 20/20 and 20/60 in 6 eyes, between 20/70 and 20/200 in 2 eyes, and worse than 20/200 in 4 eyes. No intraocular tumor recurrences or metastases occurred. Two patients developed secondary rhabdomyosarcomas; 1 patient succumbed to the disease.
CONCLUSIONS: Limbal-based cataract extraction in our series was not associated with tumor recurrence or metastasis. The optimal quiescent interval is not known; however, no tumor recurrences occurred in our series when a minimum 17-month quiescent period was achieved. Visual improvement was noted in every patient, although several patients only experienced modest gains.
