Abstract：
BACKGROUND: Panuveitis is a serious inflammatory disease. Setae are fibers produced by many insects and plants. Many case reports have described caterpillar and spider fibers entering the eye. These hairs are covered with tiny barbs that help them enter and migrate into the eye tissue, leading to severe inflammation. Normally, they are buried mainly in the conjunctiva and cornea. However, in the present case, they entered the posterior segment of the eye, which is very rare.
METHODS: A female patient presented with a complaint of repeated foreign body sensation, redness, pain, and photophobia in the left eye for 9 years following initial exposure to caterpillars. She visited the doctor in January after aggravation of symptoms. Slit-lamp examination, ultrasound biomicroscopy, ultrasound B-scan, fluorescein angiography, and indocyanine green angiography revealed the presence of a foreign body in the vitreous, which caused discomfort in the patient\'s left eye and subsequently, panuveitis of the left eye. The symptoms improved significantly after foreign body removal using vitrectomy. Microscopic examination revealed that the foreign body was caterpillar setae.
CONCLUSIONS: Clinicians should be more vigilant about history of contact with caterpillars while examining uveitis that has recurred for many years. Identification of the root cause of the disease can ensure better treatment.

摘要：
背景：全葡萄膜炎是一种严重的炎症性疾病。油条是由许多昆虫和植物产生的纤维。许多病例报告描述了毛毛虫和蜘蛛纤维进入眼睛。这些毛发上覆盖着微小的倒钩，帮助它们进入和迁移到眼睛组织中，导致严重的炎症。通常,它们主要埋在结膜和角膜中。然而,在目前的情况下,他们进入了眼睛的后段，这是非常罕见的。
方法：一名女性患者出现反复异物感，发红,疼痛,初次接触毛毛虫后，左眼畏光9年。在症状加重后，她在一月份去看了医生。裂隙灯检查,超声生物显微镜,超声B扫描,荧光素血管造影,吲哚菁绿血管造影显示玻璃体中存在异物，导致患者左眼不适，随后，左眼全葡萄膜炎。使用玻璃体切除术去除异物后，症状显着改善。显微镜检查发现异物是毛毛虫。
结论：临床医生在检查多年复发的葡萄膜炎时，应更加警惕与毛虫接触的病史。确定疾病的根本原因可以确保更好的治疗。
