Dirofilariasis is a disease rarely seen in humans, occurring commonly in noncarnivorous mammals. The microfilariae are transmitted by a mosquito vector. Ocular dirofilariasis is rarely described in the ophthalmic literature.
An 81-year-old woman living in the north of France had a history of sudden pain and swelling of the left orbit. On slit lamp examination, a white worm was seen under the superior bulbar conjunctiva. Excision of the subconjunctival worm was adequate treatment and was important for parasite identification.
Dirofilariasis is broad-based and is more common in Italy. Cases in France are found in the south. Ocular symptoms are frequently subconjunctival, but many cases of orbital involvement are found. Treatment is only surgical; systemic medication is not necessary.
Ocular dirofilariasis is exceptional. Case reports in ophthalmic literature are rare. This parasite infection is probably underdiagnosed.
丝虫病在人类中很少见，常见于非肉食性哺乳动物。微丝蚴由蚊媒传播。眼部丝虫病在眼科文献中鲜有描述。
一名居住在法国北部的81岁女性有左眼眼眶突然疼痛和肿胀的病史。裂隙灯检查时，在上睑结膜下可见一条白色蠕虫。结膜下蠕虫切除术是充分的治疗方法，对寄生虫鉴定很重要。
丝虫病分布广泛，在意大利更为常见。法国的病例多见于南部。眼部症状常表现为结膜下病变，但也有许多眼眶受累的病例。治疗仅需手术；无需全身用药。
眼部丝虫病较为罕见。眼科文献中的病例报告很少。这种寄生虫感染可能诊断不足。
