Antiphospholipid syndrome following toxoplasma retinochoroiditis.

PURPOSE: To report a case of antiphospholipid syndrome (APS) following toxoplasma retinochoroiditis.

DESIGN

Interventional case report.

METHOD: The patient was a 24-year-old female with an attack of visual loss due to toxoplasma retinochoroiditis concomitant with branch retinal vein occlusion. Retinitis resolved with anti-toxoplasma treatment. However, a recurrent episode of BRVO and vitreous hemorrhage occurred later.

RESULT: In systemic evaluation, evidence of APS was detected, including high titers of anti-cardiolipin antibody, increased beta-2 microglobulin and anti-toxoplasma IgG antibody, and also low titers of C3, C4, and CH50.

CONCLUSION

Ocular toxoplasmosis should be included in the list of etiologies of secondary APS. Systemic evaluation for detection of APS is a necessary approach to patients with toxoplasma retinochoroiditis and concomitant vascular accident.
