Infantile leukocoria caused by posterior lenticonus.
Posterior lenticonus--a bulging of the posterior capsule and cortex--is an acquired lens abnormality, which becomes increasingly opaque. We report an unusual case of bilateral posterior lenticonus in an infant, who initially presented with leukocoria and was referred with a diagnosis of retinoblastoma. Careful physical examination and ultrasound analysis were important in the diagnosis. Ultrasound also aids the surgeon in planning therapy. Posterior lenticonus should be considered in the differential diagnosis of retinoblastoma.
