  • Abstract
  • Look Inside

 A 59-year-old male developed seeing flies and blurring in his right eye 5 days before. His visual acuity was 20/20 in either eye. The right eye showed vitreous hemorrhage,retinal exudates,and a strand of hemorrhage adherent to the retina. When seen one month later,the vitreous hemorrhage had disappeared. A horseshoe-tear was present in the superior periphery surrounded by retinal detachment. Fluorescein angiography showed occlusion of superior temoral vein without hemorrhage. The retinal detachment healed after vitrectomy,photocoagulation,an tamponade with SF6. The patient kept a dog as pet in his house. While toxoplasma antibody was negative,a piece of toxocara canis was identified in the specimen form the retina. Intraocular migration of toxocara larva might have induced branch retinal vein occlusion and vitreoretinal adhesion leading to retinal tear and detachment. This case illustrates that intimate contact with pet animal may result in toxocara intection and ocular complications.
