A、用药前应行病因学检测，查明病因后再根据药物敏感试验的结果选用敏感药物。查明病因前不应贸然用药，以避免耐药菌株的产生
B、在病原学检测查明病因之前，为了不耽误病情就应使用药物治疗。但为了避免或减少耐药菌株的产生，使用药物应选择一种药物，从小剂量开始
C、若患者出现前房积脓，应选用敏感药物采用前房注射给药，以尽快控制病情
D、出现前房积脓时可使用缩瞳剂缩小瞳孔，以避免前房脓液通过瞳孔进入后房，避免感染扩散
E、急性期就应选用高浓度广谱抗菌药滴眼剂滴眼，病原学检测明确病因后，根据病因和药敏试验调整用药

正确答案
E
试题解析
感染性角膜炎急性期使用抗菌药的原则为E，A、B在不同侧面干扰了正确答案E。感染性角膜炎出现前房积脓不表现眼内出现感染，而是虹膜睫状体炎的表现。因此，C、D均是错误的。
