| Abstract |
|
Authors analysed the surgical results of superior oblique silicone expander for the treatment of superior oblique overaction in 8 patients (15 eyes) who were operated at St Mary's Hospital, Catholic University Medical College from October 1990 to December 1991. The results were as follows: 1. Preoperatively, the patients demonstrated versions of +2 overaction in 6 eyes (40%) and +3 to +4 overaction in 9 eyes (60%), And demonstrated A-patterns between 20 delta to 55 delta with a mean of 33 delta. 2. Postoperatively, of the 9 eyes with +3 to +4 overaction, 6 eyes (66.7%) showed no overaction and 3 eyes (33.3%) had +1 residual overaction. Of the 6 eyes with +2 overaction, 4 eyes (66.7%) showed no residual overaction, while 2 eyes (33.3%) had +1 residual overaction. 3. Postoperatively. reduction of A-pattern was from 16 delta to 51 delta with a mean of 27 delta. Bases on these results, it appears that the silicone expander technique is useful for the treatment of superior oblique overaction. |
