Ocular toxocariasis(OT)is an ocular parasitic disease involving ocular tissue infection by the ascarid-omatidae nematode. OT is usually caused by toxocara canis or toxocara cati. Susceptible population are more likely to be affected by their own hygiene, the frequency of exposure to dogs and cats, and the consumption of food or water contaminated with toxocariasis larvae. Most cases have been reported worldwide in children, but cases in adults have also been reported in recent years, which may be due to the lack of systematic induction and summary of its diagnosis, treatment and prognosis. In this paper, the four clinical manifestations of OT, advanced noninvasive diagnostic techniques, and laboratory immunological tests were sorted out and supplemented by reviewing domestic and international literature. Meanwhile, this paper introduced the treatment progress of OT in recent years, such as the combination of anthelmintic and hormone, and the application of intravitreal injection and vitreous surgery. It is expected that clinicians should pay more attention to this disease, improve the accuracy of early diagnosis of toxocariasis and protect patients' vision.
