Surgical repair of congenital colobomas.

Congenital colobomas usually occur as full-thickness defects of the medial third of the upper lid and are commonly associated with a benign dermoid at the apex. Exposure keratopathy and corneal trauma are rare; however, it can be prevented with the Expo Bandage--Bubble (Fig 18). Periodic examinations should also be performed. Surgical resonstruction should be performed at approximately 3 to 6 months of age and primary closure should be attempted initially. Lateral cantholysis, lid-sharing surgery, and external levator resection may be required to correct the residual deformity.
