Purpose The aim of this study is to compare the adjustable strabismus surgery with the conventional strabismus surgery. Patients and methods This is a randomized prospective study that was carried out by studying and comparing two groups of esotropia. The first group included 15 patients, in whom adjustable surgery was performed, and the second group included 15 patients, who were operated by conventional strabismus surgery, depending on the measured angle of deviation. The postoperative results were compared in the two groups on the postoperative day, and then after 1, 2, and 6 months. Results cases of the first group, had the suture attaching the muscle and tied intraoperatively by a suture, that can be advanced modified according to the resulting ocular alignment, these cases entered into the operating theatre, the second day of operation, and had the muscle suture advanced or released and tied finally so as to bring the eyes in the desired orthotropic position, but within 6 months, two patients had a residual angle of less than 10 prisms. Among the patients in the second group, in three cases, there was undercorrection as detected at the end of the follow-up period. Conclusion The results seemed comparable, the adjustable and the conventional surgery, and since the conventional surgery is requiring less manipulations and less exposure to anaesthesia, we recommend the conventional surgery in the cases when the results are predictable, and leave the choice of the adjustable suture technique in cases where the postoperative results cannot be predicted as in surgery of longstanding strabismus with known anatomical changes and to unexpected anatomical changes found during surgery. |
