To the Editor.  —Folk et al1 demonstrate that there are many visual function similarities between optic neuritis and central serous retinopathy (CSR), while suggesting that the two are easily separable ophthalmoscopically. These similarities (especially in the results of tests such as visual evoked potential [VEP] latency and critical flicker-fusion thresholds) are of unknown importance and are irrelevant to the typical clinician, who does not generally have access to these tests.See also p 394.The Farnsworth-Munsell 100-Hue Test (FM 100) is another story. It is a relatively easily administered and inexpensive test that the clinician will find particularly useful in diagnosing CSR that may not be ophthalmoscopically florid. Folk et al agreed that this test gives a pattern that is usually distinctive from optic nerve disease or at least optic neuritis. An example may be useful to stress this point.
