Outcomes of pediatric cataract surgery in anterior persistent fetal vasculature

PURPOSE: To report the intraoperative performance and postoperative outcomes in eyes with anterior persistent fetal vasculature (PFV). SETTING: Iladevi Cataract & IOL Research Centre, India, and Filatov Institute Odessa, Ukraine. DESIGN: Prospective interventional case series. METHODS: Eyes with anterior PFV had surgery using a standardized surgical technique. Plaque peeling was used for small plaques and partial excision for larger plaques. In eyes in which the entire lens converted into a fibrovascular tissue, extensive capsulectomy with anterior 2-port limbal vitrectomy was performed. Microphthalmic eyes had no intraocular lens implantation. RESULTS: This study comprised 33 eyes. The mean age at surgery was 6.30 months ± 5.16 (SD). Microcornea was observed in 10 eyes (30.3%). Within the morphology of cataract, 10 eyes (30.3%) had the lens converted into fibrovascular mass, of which 4 had associated prominent ciliary process. Anterior continuous curvilinear capsulorhexis (CCC) and manual posterior CCC were performed in 23 eyes (69.7%) and 3 eyes (9.1%), respectively. Intraoperatively, posterior capsule plaque was seen in 20 eyes (60.6%). In 31 eyes (93.9%), 2-port limbal anterior vitrectomy was performed and in 2 eyes (6.1%), pars plana vitrectomy was performed. Intraocular lens implantation was performed in 16 eyes (48.5%); 17 eyes (51.5%) were left aphakic. Visual axis obscuration was observed in 6 eyes (18.2%). At the 3-year follow-up, visual acuity remained stable in 11 eyes (33.3%) and improved in 22 eyes (66.6%). CONCLUSION: The results suggest that good visual outcomes can be obtained in PFV eyes after surgical intervention, with an acceptable rate of serious postoperative complications.
