[Congenital microphthalmos. Orbital and palpebral expansion].

Ocular atrophy in prime infancy leads to lack of orbital growth. Current treatment of plastic surgery in severe deformities is unsatisfactory, whereas tissue expanding techniques using intraorbital balloon are effective on orbital cavity growth. This procedure makes use of conjunctival shells or aesthetic ocular prosthesis easier, and allows an improved reconstruction. Description of implants and surgical technique of insertion used.
