A rare ocular dirofilariasis case along with the clinical characteristics, treatment, and outcome is reported. A whitish roundworm (10.6 cm long and 0.5 mm width) emerged from the pterygium, a triangular tissue growth on the cornea of the eye, of a male patient. The worm had a rounded anterior part, mouth without lips, smooth cuticular surface, and short rounded posterior tail with spicules: these features suggested that it was a male Dirofilaria sp. Molecular identification confirmed that the worm belonged to Dirofilaria immitis. This is the first molecular confirmation that D. immitis is a causative agent of ocular dirofilariasis in Thailand: dirofilariasis is a newly emerging zoonotic disease. Physicians should be alert to zoonotic filarial worms and knowledgeable about treatment of this disease.
报告了 1 例罕见眼部犬恶丝虫病病例，包括其临床特征、治疗和结局。1 条白色的圆形线虫（长 10.6 厘米，宽 0.5 毫米）从男性患者的翼状胬肉（眼角的三角形组织生长物）中冒出。该虫体具有圆形的前部、无唇的口、光滑的表皮表面和短而圆形的带刺的后部尾巴：这些特征表明它是雄性犬恶丝虫。分子鉴定证实该虫属于犬恶丝虫。这是首次分子确认犬恶丝虫是导致泰国眼部犬恶丝虫病的病原体：犬恶丝虫病是一种新出现的人畜共患寄生虫病。医生应警惕人畜共患的丝虫，并了解该疾病的治疗方法。
