目的 探讨术中镜检在板层角膜移植治疗真菌性角膜溃疡中的价值。方法20例真菌性角膜溃疡病人,术中板层剖切病灶,并逐层刮片作显微镜真菌检查及组织真菌培养。结果3例(15%)深层组织镜检见菌丝,改做穿透角膜移植;17例在中层及较深层未检见菌丝,做板层角膜移植。所有病例术后观察4－6个月均未见感染复发。板层角膜移植病例,术后视力提高率达 88.2%,植片透明率 76.5%。结论 术中镜检对于真菌性角膜溃疡的术式选择具有指导意义。
Objective To investigate the value of intraoperative microscopic examination in the treatment of fungal corneal ulcer with lamellar keratoplasty. Methods Twenty patients with fungal corneal ulcer were dissected from the lamellae of the fungus and examined by microscopic fungi and tissue culture. Results In 3 cases (15%), mycelium was seen in the deep tissue microscopy, and the cornea was transplanted through the cornea. In 17 cases, mycelium was not detected in the middle and deeper layers, and lamellar keratoplasty was performed. No recurrence of infection was observed in all cases 4-6 months after operation. The lamellar keratoplasty cases, postoperative visual acuity improved rate of 88.2%, transparent rate of 76.5%. Conclusions Intraoperative microscopy has instructive significance for the surgical selection of fungal corneal ulcer.
