Ophthalmomyiasis externa is the infestation of external ocular structures most commonly by Oestrus ovis, sheep nasal bot fly, which have a pupal stage in soil. Farmers and shepherds are commonly affected but rarely in urban areas. This is the first case of Oestrus ovis ophthalmomyiasis externa in California since Catalina Island 1986. No livestock exposure was noted. Manure fertilizer sourced from grazing fields of natural hosts was used on a local urban sports field and is the suspected source.

眼外蝇蛆病是最常见由羊狂蝇（Oestrus ovis），即羊鼻狂蝇，对眼外部结构造成的感染，羊鼻狂蝇在土壤中有一个蛹期。农民和牧羊人通常会受到影响，但在城市地区很少见。这是自1986年卡特琳娜岛以来加利福尼亚州首例羊狂蝇眼外蝇蛆病病例。未发现有牲畜接触史。当地一个城市运动场使用了来自天然宿主放牧地的粪肥，怀疑这是感染源。
