眼底周辺部に隆起性線維血管性増殖病変を呈する眼寄生虫症

Fibrovascular proliferation in the fundus periphery in ocular parasitosis

　周辺部網膜に隆起性線維血管性増殖塊を呈し，眼寄生虫症が疑われた8例につき報告した．免疫学的検索により2例は眼犬蛔虫症，2例は眼猫蛔虫症，1例は眼犬糸状虫症と診断された．硝子体混濁の著明な1例と牽引性網膜剥離を来した1例に対して硝子体手術を施行し良好な結果を得た．硝子体手術は視力の改善を得るのみでなく，術中に採取した眼内液の免疫学的検索により本症をより正確に診断できる．原因不明のぶどう膜炎や眼底周辺部の隆起性線維血管性増殖塊を認めた時には，眼寄生虫症を疑い積極的に免疫学的検索を施行すべきである．

We reviewed 8 cases with presumed ocular par-asitosis. All the cases were characterized by the presence of elevated fibrovascular proliferation in the peripheral fundus. Immunological examinations led to the diagnosis of infestation by Toxocara canis in 3 patients, Toxocara cati in 2, and filariasis in one.

We successfully treated 2 eyes by vitrectomy, to relieve vitreous opacity in one and tractional retinal detachment in the other. Vitrectomy was also contributary to definitive diagnosis through immunological examination of the intraocular fluid obtained during surgery.

Cases of uveitis associated with elevated fi-brovascular proliferation in the peripheral fundus should be further examined with the possibility of ocular parasitosis in mind.
