Outcomes of cataract surgery following radiation treatment for retinoblastoma.

ABSTRACT: To report the outcomes after cataract extraction in eyes previously treated for retinoblastoma.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.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.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.

Project description:PurposeTo assess the visual outcomes of cataract surgery in eyes that received fluocinolone acetonide implant or systemic therapy with oral corticosteroids and immunosuppression during the Multicenter Uveitis Steroid Treatment (MUST) Trial.DesignNested prospective cohort study of patients enrolled in a randomized clinical trial.ParticipantsPatients that underwent cataract surgery during the first 2 years of follow-up in the MUST Trial.MethodsVisual outcomes of cataract surgery were evaluated 3, 6, and 9 months after surgery using logarithmic visual acuity charts. Change in visual acuity over time was assessed using a mixed-effects model.Main outcome measuresBest-corrected visual acuity.ResultsAfter excluding eyes that underwent cataract surgery simultaneously with implant surgery, among the 479 eyes in the MUST Trial, 117 eyes (28 eyes in the systemic, 89 in the implant group) in 82 patients underwent cataract surgery during the first 2 years of follow-up. Overall, visual acuity increased by 23 letters from the preoperative visit to the 3-month visit (95% confidence interval [CI], 17-29 letters; P < 0.001) and was stable through 9 months of follow-up. Eyes presumed to have a more severe cataract, as measured by inability to grade vitreous haze, gained an additional 42 letters (95% CI, 34-56 letters; P < 0.001) beyond the 13-letter gain in eyes that had gradable vitreous haze before surgery (95% CI, 9-18 letters; P < 0.001) 3 months after surgery, making up for an initial difference of -45 letters at the preoperative visit (95% CI, -56 to -34 letters; P < 0.001). Black race, longer time from uveitis onset, and hypotony were associated with worse preoperative visual acuity (P < 0.05), but did not affect postsurgical recovery (P > 0.05, test of interaction). After adjusting for other risk factors, there was no significant difference in the improvement in visual acuity between the 2 treatment groups (implant vs. systemic therapy, 2 letters; 95% CI, -10 to 15 letters; P = 0.70).ConclusionsCataract surgery resulted in substantial, sustained, and similar visual acuity improvement in the eyes of patients with uveitis treated with the fluocinolone acetonide implant or standard systemic therapy.
