[Ectopic lens in childhood].

The authors analyze a group of 34 patients with ectopy of the lens detected in childhood and followed up for 12 years. The ectopy of the lens was not restricted to the eye but was part of numerous syndromes. The authors emphasize aetiological diagnosis, interdisciplinary collaboration and evaluation whether surgical extraction of the lens is indicated. Indication for operation is incorrigible reduction of the visual acuity below 0.3 and the imminence of complete dislocation of the lens. The long-term results of 12 operated patients are despite some complications very satisfactory from the functional aspect.
