目的 :评价板层角膜移植和穿透性角膜移植对真菌性角膜溃疡的治疗效果。方法 :以无水甘油保存的角膜片或新鲜角膜材料 ,根据真菌性角膜溃疡的面积和深度的不同行板层角膜移植术和穿透性角膜移植术 ,板层移植术中用 5%的碘酊烧灼植床表面 ,穿透性角膜移植术中应同时清除虹膜表面渗出物并以林格氏液冲洗。结果 :3 1例真菌性角膜溃疡的患者行板层或穿透性角膜移植术 ,2 9例一次手术痊愈 ,并获得良好视功能。 2例复发 ,二次穿透性角膜移植术后炎症控制。部分病例半年后再次行穿透性角膜移植术而获得较好视力。结论 :高效广谱抗生素、皮质激素的应用以及眼外伤的增多 ,增加了真菌性角膜溃疡的发病率。真菌性角膜溃疡的早期诊断 ,可以避免滥用药物。早期角膜病损区刮片镜检阳性率 80 %以上。掌握手术时机 ,正确地选择术式 ,术中彻底清除病灶是防止复发的关键。术后继续抗真菌治疗。
OBJECTIVE: To evaluate the therapeutic effect of lamellar keratoplasty and penetrating keratoplasty on fungal corneal ulcer. Methods: Corneal sheets or fresh cornea preserved with anhydrous glycerol were treated with lamellar keratoplasty and penetrating keratoplasty according to the area and depth of fungal corneal ulcer. The platelet transplants were treated with 5% iodine Burn the implant bed surface, penetrating keratoplasty should also remove the iris surface exudate and rinse with Ringer’s solution. Results: Thirty-one cases of fungal corneal ulcer were treated with lamellar or penetrating keratoplasty, and 29 cases were cured by one operation and got good visual function. 2 cases of recurrence, post-penetrating keratoplasty inflammation control. Some cases again after six months of penetrating keratoplasty and better visual acuity. Conclusion: The application of broad spectrum antibiotics, corticosteroids and ocular trauma increased the incidence of fungal corneal ulcer. Early diagnosis of fungal corneal ulcers, to avoid drug abuse. Early corneal lesions scraping mirror positive rate of 80% or more. Grasp the timing of surgery, the correct choice of surgical procedures, complete removal of intraoperative lesions is the key to preventing recurrence. Antifungal therapy was continued after surgery.
