简介
Visual axis opacification (VAO) occurs in up to 40% of pediatric patients after cataract surgery withintraocular lens implantation (IOL) even with a primary posterior capsulotomy (PPC). In both children and adult group, opacification does obscure the visual axis. However, in children after PPC, there is no capsule. Hence, the terminology VAO is used in children rather than posterior capsular opacification.
This opacification is caused by a proliferation of epithelial cells on the posterior capsule or anterior vitreous face and can hinder the optical image quality needed for normal visual development. The rate of epithelial mitotic activity is higher in children compared to adult. It can be managed by Yag laser or surgical membranectomy, the latter is preferable.
