  • Title: Supraliminal contrast sensitivity functions in recovered optic neuritis.
    Author: Tagami Y, Isayama Y, Masumi K, Bo H.
    Journal: Jpn J Ophthalmol; 1982; 26(2):205-12. PubMed ID: 7131929.
    Abstract:
    The supraliminal contrast sensitivity functions in patients with recovered optic neuritis were classified into three function types: 1) type with a decrease in sensitivity in the high and an increase in the low spatial frequency region, 2) type with flat shape as found in normal subjects, and 3) type with a decrease in the low and an increase in the high frequency region. These abnormal functions may be explained by an inhibitory interaction between two parallel channels of high and low frequency, which may have a dependence on the most central and the paracentral region in the visual fields, respectively. The measurements of the supraliminal contrast sensitivity functions are clinically useful for understanding the visual processes in cases with recovered optic neuritis.
