Atypical spherical deposition on vitreoretinal interface associated with toxoplasmic chorioretinitis.

Purpose: To report the clinical and optical coherence tomography features of spherical deposits associated with recurrent toxoplasmic chorioretinitis.

Methods: Case report.

Results: Atypical, 100 microm to 150 microm, greyish deposits appeared along retinal arteries and veins as well as on the vitreoretinal interface in the macula of a 44-year-old Caucasian woman while she was being treated for recurrent toxoplasmic chorioretinitis with antiparasitic drugs and subconjunctival injection of betamethasone. They disappeared progressively with the systemic use of corticosteroids. Their clinical course was nicely documented by optical coherence tomography.

Conclusions: Greyish spherical deposits on the vitreoretinal interface have been previously described as inflammatory reactions in asymptomatic human T-lymphotropic virus type I (HTLV-1) carriers and in patients with HTLV-1-associated uveitis. For the first time, optical coherence tomography (OCT) provided clinical correlation of this unusual presentation of toxoplasmic chorioretinitis.
