Abstract

In order to study the surgical of the vertical transposition of the horizontal rectus muscles for AV syndrome, we reviewed 32 cases of AV syndrome not showing significant oblique dysfunction in the department of Pediatric Ophthalmology in Seoul National University from 1986 to 1992. We performed half-tendon width vertical transposition of the horizontal rectus muscles with standard horizontal recession and resection procedure. The subgroups of AV syndrome were consisted of A esotropia 17 cases, A exotropia in 5 cases, V esotropia in 1 case, and V exotropia in 9 cases. The preoperative vertical incomitance of 18.7PD (average) was changed to 1.9PD postoperatively, so 16.8 PD (89.8%) of vertical incomitance was corrected. The AV pattern was eliminated in 31 cases (96.9%) except one. The mean follow-up period was 17.8 months.
