Congenital unilateral lamellar cataract

Lamellar or zonular cataract is a hereditary cataract that is transmitted in an autosomal dominant mode. The crystalline opacities are located at the level of the primary fibers in the embryonic nucleus. This cataract is usually bilateral and asymmetrical. Sometimes the whole nucleus can be affected causing a signifi cant decrease in visual acuity. We report the case of a 19-year-old patient who was consulting for a decrease in visual acuity. Ophthalmic examination revealed unilateral lamellar cataract.
