Abstract:Congenital cataract is one of the leading causes of childhood blindness and congenital membranous cataract is a rare and special type of congenital cataract. The lens fibre of congenital membranous cataract is degenerative and its cortex is absorbed gradually. Congenital membranous cataract also has another name, pseudoaphakia, due to the similar phenotype with posterior capsule opacification after cataract surgery, but without intraocular refractive power. There are few reports on congenital membranous cataract at home and abroad, and the research on the pathogenesis of congenital membranous cataract is even less. Clarifying the pathogenesis of congenital membranous cataract, especially the genetics, is very helpful for us to understand the pathogenesis of congenital cataract and the molecular mechanism of lens development.
