Inferolateral migration of hydrogel orbital implants in microphthalmia.

Purpose: Hydrogel spheres may be useful in treating orbital hypoplasia associated with congenital microphthalmia. The authors describe migration associated with the use of these devices.

Methods: The authors retrospectively reviewed 5 cases in which a hydrogel orbital expander (Osmed) was implanted to treat orbital hypoplasia in pediatric patients with congenital microphthalmia (with or without previous surgery).
