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.

Project description:Importance:Primary epiretinal membrane (ERM) is a common retinal disorder with a prevalence of 4% to 18.5%. Although ERM and cataracts commonly occur together, to our knowledge, no studies have investigated the outcome of cataract surgery alone in this setting. Objective:To analyze the visual outcome and cystoid macular edema risk with cataract surgery in eyes with primary ERM. Design, Setting, and Participants:In this retrospective clinical database study, data were collected from July 2003 to March 2015 from 8 locations in the United Kingdom. Cataract surgery data of 217?557 eyes were extracted from the electronic medical record of the UK National Health Service. After exclusion of 57?561 eyes with combined surgery, prior vitrectomy, copathology, and complications, 812 eyes with primary ERM and 159?184 reference eyes were analyzed. Main Outcomes and Measures:We report on visual acuity (VA), the incidence of cystoid macular edema, and the need for ERM surgery. Results:The mean (SD) age of patients in the ERM group was 73.7 (9.23) years, and 395 of 812 were men (46.8%). The mean (SD) age of patients in the reference group was 74.4 (12.19) years, and 65?265 of 159?184 were men (41%). Epiretinal membrane eyes assessed at 4 to 12 weeks postoperatively gained 0.27 (0.32) logMAR (approximately?3 Snellen lines), with 200 of 448 (44.6%) improving by 0.30 logMAR or more (?3 Snellen lines) and 32 of 448 (7.1%) worsening by 0.30 logMAR or more. Reference eyes gained a mean (SD) of 0.44 (0.26) logMAR (approximately?4 Snellen lines), with 48?583 of 77?408 (62.8%) improving by 0.30 logMAR or more and 2125 of 77?408 (2.7%) worsening by 0.30 logMAR or more. Although all eyes with preoperative VA of 20/40 or less improved, only reference eyes with preoperative VA of more than 20/40 showed improvement. Cystoid macular edema developed in 57 of 663 ERM eyes (8.6%) (95% CI, 6.69-10.98) and 1731 of 125?435 reference eyes (1.38%) (95% CI, 1.32-1.45) (P?<?.001). Epiretinal membrane surgery was performed in 43 of 663 (6.5%) ERM eyes. Conclusions and Relevance:On average, VA improved 0.27 logMAR (approximately 3 Snellen lines) in eyes with ERM. Eyes with ERM and VA of 20/40 or less showed more benefit after cataract surgery than those with better preoperative vision. However, compared with eyes without ERM, higher rates of cystoid macular edema and a lower postoperative VA gain were noted.
