Visual function and macular architecture in patients with inactive zone 2 and 3 toxoplasmic retinochoroiditis.

Purpose: To evaluate the visual function and architecture of the central and peripapillary retina in patients with inactive toxoplasmic retinochoroiditis outside the macular and peripapillary regions (zones 2 and 3).

Methods: Cross-sectional study of 20 eyes (18 patients) with zone 2 and 3 toxoplasmic scars and visual acuity ≥20/25. Patients underwent Humphrey 10-2 perimetry, contrast sensitivity (Mars test), and color vision testing (L'Anthony desaturated D-15).
