  • Title: A study of spectral electroretinogram of color vision defects due to macular diseases.
    Author: Tian N, Wu DZ, Liang J.
    Journal: Yan Ke Xue Bao; 1994 Sep; 10(3):163-7. PubMed ID: 7744208.
    Abstract:
    Studies of spectral electroretinograms in central serous retinopathy (CSR) and hereditary macular degeneration (HMD) showed that the b-wave amplitudes of most wavelengths of CSR were significantly decreased as compared with normal controls, and those of HMD were obviously lower than the normal values. Patients of HMD with type-A color vision defects (CVD) had primarily a reduction of b-wave amplitudes in the full spectrum of 480-620 nm, and patients with type-I CVD a reduction of b-wave amplitudes wave-lengths of 480-560 nm. These differences might reflect differences in damages to the medium-and long-wave length.
