Differentiation between recently resolved optic neuritis and central serous retinopathy. Use of tests of visual function.

A test battery was performed on 13 patients with resolved central serous retinopathy and on 13 patients with resolved optic neuritis to see whether the tests would help to distinguish between the two conditions. We found that the most useful discriminators were the relative afferent pupillary defect, followed by the visual evoked potential latency and the critical flicker frequency. The total error score on the Farnsworth-Munsell 100-Hue Test and the nature of the color vision defect were not helpful in separating the two diseases.
