| Abstract: | Background: Treatment of ocular toxoplasmosis is aimed at stabilizing visual function and reducing recurrence rates.Methods: Small controlled studies indicate that available treatments do not affect visual outcome and recurrence rates, and no antibiotic in current use will kill bradyzoites.Results: Antiparasitic treatment is justified in center-involving lesions and in large aggressive lesions namely in South American patients. Antibiotic treatment is needed for disease in the immunosuppressed, and this needs to be systemic. There exists strong agreement that a monotherapy, using steroids, is contraindicated. Prophylactic antibiotics may reduce recurrence rates in endemic areas and immunosuppressed patients.Conclusion: An ideal therapeutic strategy includes the strain of parasite, localization of the lesion, and severity of the inflammatory response as a basis for therapeutic decision making. New treatments targeting aspects of the parasite s physiology are very promising. On a global scale, public health measures to prevent transmission from animals and to access potable water are required. |
