ABSTRACT

Toxocariasis is a parasitic zoonosis. A description is provided of the anatomical and functional alterations produced by membranes that pull the posterior pole and the periphery of the retina, causing partial vitreous hemorrhage associated to neovascularization of the optic disk with epiretinal membrane, and a lamellar macular hole related to the presence of peripheral granuloma. A clinical case is presented of a healthy male patient who started out with a decrease in the visual acuity of his left eye and was diagnosed with a complicated ocular toxocariasis based on his clinical status and ophthalmological examination with a positive toxocara test. Minimally invasive vitrectomy was performed: 23G associated to membranectomy and internal limiting membrane peeling, as well as panretinal laser endophotocoagulation, using patient positioning and gas (SF6) as tamponade at the end of surgery. Systemic steroid and antiparasitic treatment was provided before surgery, and satisfactory anatomical and functional results were obtained.
