Abstract :
PURPOE:
To compare the potoperative reult of adjutable-uture trabimu urgery when uture adjutment wa performed 8 hour (group 1) and 24 hour (group 2) after urgery.
METHOD:
A retropective clinical tudy wa conducted in two hopital. trabimu urgery and mucle adjutment were performed in 90 patient. All patient had horizontal trabimu (40 patient had eotropia and 50 patient had exotropia), and they underwent either primary urgery or reoperation. Mean age of the patient wa 29.9 ± 14.1 (range, 14 to 74) year. The angle of deviation wa meaured in all patient before urgery, after urgery both before and after adjutment, and at the final follow-up examination. The follow-up period wa 6 to 40 month (mean, 19.6 month).
REULT:
Preoperative data were imilar in the two group. The mean angle of deviation immediately after mucle adjutment wa 0.6 ± 6.1 prim diopter in group 1 and 0.4 ± 6.3 prim diopter in group 2. Thi imilar deviation in the two group (P = .9) changed during the follow-up period, and at the final examination the meaured angle in group 1 and 2 were −1.0 ± 7.9 and −2.5 ± 10.3 prim diopter, repectively (P = .48). The mot coniderable outcome meaure wa the calculated drift value. At the lat follow-up thee value were −1.6 ± 5.8 for group 1 and −2.9 ± 11 prim diopter for group 2 (P = .5). ubdividing the patient on the bai of their deviation before urgery, a potoperative drift toward exotropia wa found in mot patient of group 1. In group 2, however, a greater tendency toward exotropia wa hown only by thoe patient who had diplayed exotropia preoperatively, wherea patient with preoperative eotropia howed a greater tendency toward eotropia after urgery.
CONCLUION:
In patient undergoing horizontal extraocular mucle urgery with adjutable uture, uture adjutment 8 hour or 24 hour after urgery did not produce ignificantly different reult.
