Clinical-Epidemiological Characterization of Ocular Toxocariasis

Abstract

Objective: To characterize ocular toxocariasis clinically and epidemiologically.

Methods: An observational, descriptive and cross-sectional study was conducted with patients diagnosed with ocular toxocariasis, attended at the Instituto Cubano de Oftalmología Ramón Pando Ferrer in the period from April 2019 to December 2022.

Results: The male sex predominated (53.7 %), together with the age group 0-10 years (73.1 %). 56.1 % of the patients lived in rural areas. Cohabitation with domestic animals accounted for 75.6 %. The most frequently reported symptom was decreased visual acuity (48.8 %). The most frequent form of presentation was peripheral granuloma in the right eye (52.4 %). The most observed complication was retinal detachment (58.5 %).

Conclusions: Ocular infection by Toxocara spp. is a preventable, as well as incapacitating, disease that limits the educational, occupational and general life development of affected patients, particularly children, males and those living in rural areas cohabitating with domestic animals, especially dogs.
