Described are four cats diagnosed with ophthalmomyiasis externa caused by larvae. Medical records were retrospectively reviewed to identify cats with ophthalmomyiasis externa between 2005 and 2020 at Cornell University Hospital for Animals. Signalment, history, clinical and diagnostic findings, treatment and outcome were recorded. All cats were young (< 3 years of age), had outdoor access and were initially examined during the summer months. All cases had unilateral disease with the right eye affected. Two cases had nictitating membrane lesions and two had orbital disease. Concurrent superficial corneal ulceration was present in three cats. Two cats suffered from pyrexia, suspected secondary to inflammation from the larval infestation. Successful larval removal was performed in all cats, which resulted in improvement of discomfort and clinical signs. A corneal ulcer persisted in one cat, which was lost to follow-up prior to ulcer resolution. Parasite identification confirmed species infestation in all cases.
To the authors' knowledge, this is the first report of feline ophthalmomyiasis externa caused by species. Parasite removal was successful in restoring comfort and resolving clinical signs in all cats with adequate follow-up information.
描述了 4 只被诊断为外眼肌蝇蛆病的猫，这些猫的幼虫。回顾了康奈尔大学动物医院 2005 年至 2020 年间患有外眼肌蝇蛆病的猫的病历，以确定其特征、病史、临床和诊断发现、治疗和结果。所有猫均为幼猫（<3 岁），有户外活动史，最初在夏季进行检查。所有病例均为单侧疾病，右眼受累。两例有瞬膜病变，两例有眼眶疾病。三例同时伴有浅层角膜溃疡。两例猫发热，疑似幼虫感染引起的炎症所致。所有猫均成功地取出了幼虫，这导致不适和临床症状得到改善。一只猫的角膜溃疡持续存在，在溃疡愈合之前，这只猫失访。寄生虫鉴定证实所有病例均为 种寄生虫感染。
据作者所知，这是首次报道由 种引起的猫外眼肌蝇蛆病。在所有有足够随访信息的猫中，寄生虫的清除成功地恢复了舒适度，并解决了临床症状。
