ABSTRACT
We examined the variations in the limbus-insertion distance, the width and the insertion shape of 260 horizontal recti muscles in 137 strabismic patients, and evaluated the relationship between insertion shape and postoperative results. The average limbus-insertion distance of medial rectus muscle was 4.72 +/- 0.49mm and that of lateral rectus muscle was 6.29 +/- 0.58mm. The width of medial rectus and lateral rectus mascle was 9.84 +/- 0.83mm and 9.57 +/- 0.84mm. The insertion shapes of horizontal rectus muscle were divided into 5 groups, straight, oblique type I and II, concave and convex patterns. According to insertion shape, insertion shape of the medial rectus muscle had no statistic difference in esotropia and exotropia(P=0.179), but in case of the lateral rectus muscle, it was staistically significant in both exotropia and esotropia(P=0.036). When the deviation angle was larger than 40 delta, the length of limbus width was statistically significant in lateral rectus muscle(P=0.018). The insertion shape divided into straight and non-straight pattern was statistically insignificant on postoperative success rate.

Retrospective study was conducted in 13 eyes of 9 Behcet's disease patients who have undergone cataract extraction with or without intraocular lens implantation. According to Shimizu's criteria, 5 eyes(55.6%) were classified as incomplete type and 3 eyes(33.3%) as suspect type. Among 13 eyes, only 3 eyes achieved final visual acuity of 0.1 or better and 4 eyes resulted in final visual acuity of 0.01 or worse. Postoperative complications included after-cataract in all 11 eyes which had undergone extracapsular cataract extraction(ECCE) and vitreous opacity in 10 eyes. Our results shows that the visual prognosis after cataract extraction is poor in general, although it may be improved in selected cases if inflammation has been controlled for a sufficient duration.
