Photography is considered as one of the most important means to promote evidence-based medical practice in pediatric ophthalmology.This study is to investigate the feasibility of congenital cataract morphological classifications and monitoring using slit-lamp-adapted anterior segmental photography in a large cohort that included uncooperative children.

Lens opacities in congenital cataracts have a wide range of presentations.Therefore, it is important to find a method of recording, classifying and monitoring cataract morphologies that is feasible and safe in a large cohort of children with congenital cataracts, including uncooperative children. Photography is considered as one of the most important means to promote evidence-based medical practice in pediatric ophthalmology.

In this study, the investigators studied congenital cataract morphological classifications and monitoring using slit-lamp-adapted anterior segmental photography and evaluated its safety and feasibility in pediatric cataract patients registered in the Childhood Cataract Program of the Chinese Ministry of Health.
