A 63-year-old patient suffering from old sclerokeratitis was fitted with a therapeutic soft contact lens one and a half years after corneal transplantation and half a year after cataract surgery. The patient was on oral and local cortisone treatment. The first three months were uneventful with an aphakic high water content lens worn continuously. This lens was lost and she was given a B-L plano T. One month later the patient was admitted to the hospital with a red eye and a large corneal ulcer. Two white spots were noted on the contact lens. In a frozen section yeast-like structures were seen on the lens that partly invaded the lens material. Fungal culture from the other deposit revealed candida tropicalis and fusarium. The corneal ulcer healed with antimycotic therapy. The possible relationship between cortisone treatment, corneal ulcer and fungal contamination of the lens is discussed.
一名63岁患有陈旧性巩膜角膜炎的患者，在角膜移植术后一年半及白内障手术后半年，佩戴了治疗性软性角膜接触镜。患者正在接受口服和局部皮质类固醇治疗。最初三个月情况平稳，一直佩戴无晶状体高含水量镜片。该镜片丢失后，给她佩戴了一片B-L平光T型镜片。一个月后，患者因眼红和角膜大溃疡入院。在角膜接触镜上发现两个白点。在冰冻切片中，在镜片上看到酵母样结构，部分侵入镜片材料。从另一个沉积物进行的真菌培养显示有热带念珠菌和镰刀菌。角膜溃疡经抗真菌治疗后愈合。文中讨论了皮质类固醇治疗、角膜溃疡与镜片真菌污染之间可能的关系。
