| 1 | Experimental Study on the Prevention of Anterior Segment Ischemia by Preservation of Anterior Ciliary Vessels显示文摘Purpose: To observe the effect of preserving anterior ciliary vessels (ACVs) on anteriorsegments of rabbit eyes undergoing tenotomy of extraocular muscles.Methods: Thirty-two adult New Zealand white rabbits were divided into four groups.Same procedures were done in both eyes in each group except that left eyes underwentpreservation of ACVs. In the first group medial and lateral recti, in the second group,superior and inferior recti, in the third group, medial, lateral and superior or inferior rectiand in the fourth group, all four recti, underwent tenotomy. Slit-lamp examination,intraocular pressure (IOP) measurement, total protein and lactic acid quantification inaqueous humor were done in all eyes pre- and post-operatively. By four weeks afteroperation, the eyes were enucleated for histological examination and electron microscopy.All data were analyzed using SPSS version 10.Results: In the left eyes of both group 1 and group 2, no inflammatory response wasobserved. In the left eyes of group 3 and 4, we observed mild inflammatory response withslit-lamp examination, which disappeared in one wk. However, we did not findsignificant changes in IOP, total protein and lactic acid of aqueous humor, histology andelectron microscopic examination in these groups. In the right eyes in group 2, 3 and 4,we observed moderate to severe inflammatory changes, a few even developed anteriorsegment ischemia, appeared as decreased IOP, increased total protein and lactic acid inaqueous humor, along with pathological and electron-microscopic changes.Conclusion: Simultaneous tenotomy of three or four recti or two vertical recti on one eyemay decrease anterior segment blood flow even lead to ischemia. ACVs preservation mayprotect the blood circulation in anterior segment. Our study suggests that ACVspreservation in strabismus surgeries especially those involving multi-recti tenotomies mayprevent potential anterior segment ischemia. | YannaLi GuanghuanMai ZhijianWang XinpingYu HuanyunYu] YanGuo XiaomingLin DamingDeng YingKang | 2003 | Eye Science2003，19，1： | 1 |
| 2 | Clinical Features and Surgical Treatment of A-pattern Exotropia显示文摘Purpose: To investigate the clinical characteristics and determine the effective surgical managements of A-pattern exotropia.Methods: Thirty-two patients with A-pattern exotropia underwent superior oblique muscle weakening procedures, medial rectus resection or (and) lateral rectus recession. Pre- and post-operative eye position, deviation angle, superior oblique function and binocular vision were examined and analyzed in the cases.Results: Overaction of the superior oblique muscles (31/32) and underaction of the medial rectus muscle (20/32) were presented in the cases. Postoperatively, a satisfactory ocular alignment was obtained in 28 cases (87.5%), and the A-pattern was corrected in 31 cases (96.9%). Four cases got binocular vision after surgery.Conclusions: As one of the most common forms of A and V patterns, A-pattern exotropia showed clinical characteristics of superior oblique muscle overaction and medial rectus muscle underacion, which should be the primary factors in the etiology of A-pattern exotropia, and superior oblique weakening procedures combined with horizontal surgery should be an effective approach to A-pattern exotropia treatment. | JingchangChen GuanghuanMai DamingDeng XiaomingLin YanGuo XiaoYang ChunxiuYuan | 2004 | Eye Science2004，20，3： | 1 |
