Area of Science:

  • Infectious Diseases
  • Ophthalmology
  • Parasitology

Background:

  • Toxoplasmosis is a globally prevalent parasitic infection affecting humans and animals.
  • Caused by the protozoan parasite Toxoplasma gondii, it presents diverse clinical outcomes.
  • The infection can be congenital or acquired, ranging from asymptomatic to life-threatening generalized disease.

Purpose of the Study:

  • To summarize the epidemiology and clinical manifestations of toxoplasmosis.
  • To specifically detail the ocular manifestations and pathological impact of Toxoplasma gondii infection.

Main Methods:

  • Review of existing literature on toxoplasmosis.
  • Analysis of clinical presentations and pathological findings associated with ocular toxoplasmosis.

Main Results:

  • Toxoplasma gondii infection has a worldwide distribution in various hosts.
  • Ocular toxoplasmosis presents with sudden vision blurring and floaters.
  • Pathology involves localized necrotizing retinitis and adjacent choroid inflammation, with the retina being the primary site of injury.

Conclusions:

  • Toxoplasmosis is a significant public health concern due to its widespread nature.
  • Ocular involvement is a critical manifestation, leading to potentially severe vision impairment.
  • Understanding the pathogenesis of ocular toxoplasmosis is crucial for diagnosis and management.
