    Cataract/Anterior Segment

    Lamellar, or zonular, cataracts are the most common type of congenital cataract. They are characteristically bilateral and symmetric, and their effect on vision varies with the size and density of the opacity. They may be inherited as an autosomal dominant trait. In some cases, they may result from a transient toxic influence during embryonic lens development. Notes: A 15-year-old patient presented to us with right exotropia with poor fixation and a lamellar cataract. Management depends on the size and density of the lamellar opacity. In early cases, refractive correction may be a line of management, but in significant opacities, cataract removal and IOL implantation is required.
