Association Between Ocular Trauma and Activation of Ocular Toxoplasmosis

ABSTRACT

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.
