Clinical Analysis in Adjustable Strabismus Surgery; 1. Recession in Horizontal Correction

ABSTRACT

Adjustable suture strabismus surgery was performed in 4 cases of horizontal strabismus from February, 1987 to July. 1938. We evaluated the type of strabismus. the chance and effect of adjustment, and the results of deviation in 31 cases which were followed up mean 6 months(minimum 2 months and maximum 14 months). We also analyzed the results in 15 cases of conventional recession-resection operation in large-angled horizontal strabismus(mean follow-up; 16.2 months). The results were as follows 1. The angle of deviation before operation was minimum 30 prism to maximum over 90 prism, and large-angled(over 45 prism) strabismus 22 cases(71.0%). Associated ocular abnormalities were amblyopia(20 cases), anisometropia(9 cases), corneal leukoma(2 cases), aphakia(2 cases), and retinal disease(2 cases). 2. The methods of adjustable suture were Schwartz technique(21 cases), Jampolsky's (10 cases). Adjustment was performed 13 of 31 cases. 3. The cases of success in Schwartz technique were 15 of 21 cases and in Jampolsky's 4 of 10 cases. The cases of success with adjustment were 9 of 13 cases and without adjustment were 10 of 18 cases. 4. The results of 15 cases in the conventional surgery were 5 cases of success, 2 cases of improvement, and 8 cases of failure.
