Representative example of infected nonneuronal cells that are often separated large distances from other infected nonneuronal cells. (A) Infected optic nerve before analysis; (B) infected optic nerve after scoring. White circles have been placed around infected nonneuronal cells that are separated from other infected cells by at least 75 μm, and black circles have been placed around cells that are closer than 75 μm to other infected nonneuronal cells. Each circle is 150 μm in diameter.
