Purpose:
To evaluate the association between ocular trauma and activation of ocular toxoplasmosis.
Methods:
Retrospective review of 686 patients with ocular toxoplasmosis and its association with trauma to the eye or the head within 1 week of activation.
Results:
Ten patients with a history of trauma and activation of ocular toxoplasmosis were detected (10/686; 1.45%). Nine patients showed a primary focus of retinitis without a previous scar and one patient had a recurrent form of ocular toxoplasmosis. From these 10 patients, Toxoplasma IgG was positive in eight of them. The median age of the patients was 35.8 years-old (range 17 to 65).
Conclusions:
These cases suggest that trauma can be associated with activation of retinal bradyzoite cysts in ocular toxoplasmosis.
