摘要
目的 评估兔玻璃体内注射氟康唑治疗外因性真菌性眼内炎的效果。方法 大白兔玻璃体内接种白色念珠菌后不同时间玻璃体内注射氟康唑 10 0 μg或二性霉素B 5 μg,以间接检眼镜检查、玻璃体腔穿刺真菌培养及组织学检查等方法评估药物的疗效。结果 早期用药 ( 1h、18h) 2天时玻璃体仍清晰 ,与对照组比较存在显著性差异 ,此后玻璃体进行性混浊 ,与对照组比较无显著性差异 ;后期用药 ( 3天、5天 )玻璃体混浊仍继续进展 ,与对照组比较无显著性差异。真菌培养阳性率仅为 11 1%。感染眼标本光镜下均见玻璃体腔内形成霉菌性脓疡 ,并见PAS染色 ( +)的菌丝及孢子。结论 玻璃体内注射氟康唑治疗外因性真菌性眼内炎无明显疗效 ,玻璃体穿刺真菌培养阳性率较低 ,治疗上应以联合玻璃体切割术为宜。
ObjectiveTo investigate the efficacy of intravitreal fluconazole in treating exogenous fungal endophthalmitis in rabbit.MethodsAlbino rabbits were infected with an intravitreal inoculation of 1,000 CFU of susceptible Candida albicans and received treatment at random with intravitreal injection of fluconazole 100μg or Amphotericin B 5μg in different time after inoculation,or no treatment.The effect was assessed within 4 weeks after treatment by funduscopy,quantitative vitreous culture,and Histopathology.ResultsVitreous was clearer in the early treatment groups (1,18 hours) than that of control group on 2 days after inoculation,then there was progressive vitreous clouding.Vitreous clouding progressed in the later treatment groups (3,5 days) after therapy and no significant difference compared with the control group.The positive rate of vitreous puncture culture was low.Histopathologic examinations showed vitreous abscesses and fungal elements.ConclusionIntravitreal fluconazole is useless for treatment of exogenous candida endophthalmitis,the positive rate of vitreous puncture culture is low.
