RESUMEN
OBJECTIVE: To evaluate the effect of silicone union of orbital periosteum and eyeball under muscle belly on the treatment of fixed paralytic strabismus. METHODS: The data from 23 cases (23 eyes) which included esotropia (22 eyes) and exotropia (1 eye) was collected, 11 and 12 patients were diagnosed as complete-fixed strabismus (CFS) and sub-fixed strabismus (SFS) respectively. After antagonist recession was completed, a silicone union (1 mm of its diameter) was used to make a connection between the anterior sclera of paralytic muscle insertion and lateral or medial canthus periosteum of orbital. Eyeball position was adjusted to orthophoria by the traction of silicone union. RESULTS: Orthophoria was obtained in all of 23 eyes. Eyes rotation compared with normal eye toward paralytic side were 25% (5 eyes), 50% (2 eyes), 75% (3 eyes) respectively after surgery. CONCLUSION: Silicone union is a elastic material, it is one of better methods for the correction of fixed strabismus.
