Summary

Congenital cataracts (CC) are the leading cause of childhood visual disabilities and treatable childhood blindness worldwide1. CC patients have a wide range of presentations of lens opacities and are generally categorized into several groups based on the etiologies, anatomical positions, or shapes of lens opacities. Cataractous eyes of CC patients are also frequently complicated with other anterior segment abnormalities due to their close anatomical relationships and similar developmental origins. Lens opacities in different positions may be related to specific anterior segment abnormalities; for example, anterior polar cataracts are associated with greater corneal astigmatism (CA). However, no studies have systematically related the position of lens opacities to specific anterior segment abnormities, mainly due to the small number of CC patients, a lack of proper equipment, and a lack of awareness of these important relationships.
