Abstract

Purpose: To investigate the morphological types and delineate the clinical and surgical variables associated with VAO in children undergoing pediatric cataract surgery. Methods: We included 33 eyes of 28 children who developed clinically significant visual axis opacification (VAO) after congenital or developmental cataract surgery. All eyes underwent a comprehensive examination under anesthesia followed by a membranectomy to clear the visual axis. We classified VAO into three subgroups: fibrotic, proliferative, and combined morphologies. We reviewed and analyzed the retrospective data and the findings during membranectomy to identify the etiological variables associated with various morphologies of VAO. Results: The median age at primary surgery was 7 (2–96) months. The median interval from primary surgery to the first documentation of VAO was 6 (1–22) months. Younger children developed VAO sooner than older children. VAO was fibrotic in 11 eyes (33%), proliferative in 18 eyes (54.5%), and combined in four eyes (12.12%). Most children with fibrotic VAO belonged to economically disadvantaged sections of society (P = 0.04). Conclusion: Lower age at primary surgery was the predominant risk factor for the development of VAO. Besides primary posterior capsulotomy and adequate anterior vitrectomy, a strict adherence to anti- inflammatory measures and follow up in necessary to prevent the occurrence of VAO. A close follow-up facilitates early detection and management, which can prevent the onset of visually impairing amblyopia.
