    摘要:

    目的:报告1例使用5mg/L两性霉素成功治疗难治性真菌性角膜炎的病例。方法:病例报告。结果:女性患者1例,48岁,以右眼红1wk,伴视力下降和角膜混浊2d入院。否认有外伤或异物史。检查发现:右眼视力:6/12,针孔视力:6/18。注射结膜前使眼分泌物保持最少。角膜旁中央区有一全层基质脓肿-形态不规则且伴有卫星病灶及羽状边缘,不伴有上皮缺损,有前房积脓液平。左眼正常。诊断为真菌性角膜炎。尽管在此前患者经历了3wk的局部两性霉素B点眼(1次/2h),那他霉素眼液点眼(1次/4h),但并无病情恢复的迹象。相反12点出现了一个新的更大的基质脓肿病灶。我们应用5mg/L两性霉素B角膜基质注射联合穿透性角膜移植术治疗后溃疡面积明显减少,前房积脓完全消失,没有毒性反应发生。患者干预后2mo视力恢复了正常视力(6/6)。结论:使用两性霉素B5mg/L基质内注射,使用过程安全有效,是一种治疗难治性真菌性角膜炎的理想方法。

    Abstract:

    ·AIM:To report a successful intrastromal injection of amphotericin B 5mg/L in a refractory fungal keratitis.·METHODS:An interventional case report·RESULTS:A 48-year-old lady presented with history of redness of the right eye for one week duration followed by decrease in vision and corneal opacity for two days.There was no history of trauma or foreign body.Examination revealed visual acuity of 6/18 with pinhole of 6/12 of the right eye.The conjunctiva was injected with minimal eye discharge.There was a full thickness stromal abscess at the paracentral area of the cornea.It was irregular,feathery margin with few satellite lesions.There was no epithelial defect noted.Hypopyon level was also seen.The left eye was normal.A presumptive diagnosis of fungal keratitis was entertained.Despite three weeks of intensive treatment with topical amphotericin B every 2 hours and natamycin every 4 hours and antibiotic cover,the lesion showed no sign of resolution.It grew larger and a new focal lesion of stromal abscess appeared at the 12 o’clock position.We decided to proceed with an intrastromal injection of amphotericin B 5mg/L in lieu of therapeutic penetrating keratoplasty.The size of the ulcer was substantially reduced with total disappearance of hypopyon.There was no ocular toxicity observed following the intervention.Patient regained her normal visual acuity of 6/6 after 2 months of intervention.·CONCLUSION:An intrastromal injection of amphotericin B 5mg/L provides an alternative method of treating refractory fungal keratitis.It is also shown to be an effective and safe procedure with promising results.·
