  • Title: A colour-flicker analysis of visual function in patients with retinal detachment.
    Author: Fahle M, Troscianko T, Kreissig I.
    Journal: Ger J Ophthalmol; 1992; 1(5):367-70. PubMed ID: 1477643.
    Abstract:
    Patients with a history of retinal detachment were examined by the following tests: (1) setting of an isoluminant match between yellow and green constituent squares of a checkerboard and (2) measurement of the flicker fusion frequency for a contrast-reversal of this yellow-green pattern. The results suggest that the test may provide useful data for assessing the severity of any damage to a given part of the retina. The fusion frequencies range from over 10 Hz (normal) to about 2 Hz for a severely impaired retina. The data for the relative amounts of red and green light needed to achieve a match rarely show any abnormality; thus, a standard anomaloscope test or pseudoisochromatic plates would not detect these deficiencies.
