Congenital Cataract Morphological Classifications

Congenital Cataract Morphological Classifications and Monitoring Using Slit-Lamp-Adapted Photography in CCPMOH

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.

The eligible patients underwent pupil dilation and slit-lamp-adapted anterior segmental photography to electronically record and monitor the morphology of their cataractous lens.

All eligible pediatric patients underwent pupil dilation with compound tropicamide eye drops 3 times (1 time every 10 minutes) before the examination or administration of sleep aid medicine. Then, the children underwent slit-lamp-adapted anterior segmental photography (BX900, Haag-Streit AG, Köniz, Switzerland) for each cataractous lens, including one diffuse light photo, one slit-light photo across the cataract and one retro-illumination photo. All photos of the included patients were screened and morphologically classified separately by two pediatric ophthalmologists; a third ophthalmologist was masked and required to make a decision if the first two physicians had different opinions.

Inclusion Criteria: Children with pediatric unilateral/bilateral cataracts Children who were younger than 10 years of age Exclusion Criteria: Premature birth Microphthalmia Micro-or Megalocornea Keratoconus Glaucoma Traumatic or complicated cataracts Vitreous and retinal diseases Any previous surgeries, and contraindication for pupil dilation and sedation
