spp. are leading fungal pathogenes in contact lens associated keratitis and may evoke endophthalmitis. Since spp. are highly resistant to antifungal drugs, globe integrity is threatened. A woman developed fungal anterior chamber involvement after contact lens associated corneal ulcer formation. She presented with a painful eye with hypopyon and a mass presumably of fungal origin growing on the iris and anterior lens capsule. A biopsy confirmed . Only multiple lavages of the anterior segment with Amphotericin B achieved convalescence. In the initial stage of contact lens associated keratitis, it is often hard to differentiate between etiology. However, keratitis which are treatment resistant to antibacterials are suspicious for fungal origin. For proper treatment, identification of pathogen is crucial. Due to poor tissue penetration of the lipophilic anti-fungal agents and slow fungal replication rate, multiple lavages of the anterior chamber are often required to handle fungal infections.
某菌种是隐形眼镜相关性角膜炎的主要真菌病原体,可能引发眼内炎。由于该菌种对抗真菌药物高度耐药,眼球完整性受到威胁。一名女性在隐形眼镜相关性角膜溃疡形成后出现真菌性前房受累。她表现为眼痛伴前房积脓,虹膜和晶状体前囊上有一个推测为真菌来源的肿物。活检证实为该菌种。仅用两性霉素B对前段进行多次冲洗才使病情康复。在隐形眼镜相关性角膜炎的初始阶段,病因往往难以区分。然而,对抗菌药物治疗耐药的角膜炎怀疑为真菌来源。为了进行恰当治疗,病原体鉴定至关重要。由于亲脂性抗真菌药物的组织穿透力差以及真菌复制速度慢,处理真菌感染通常需要对前房进行多次冲洗。
