Comparison of Flicker Perimetry With Standard Perimetric Methods

Critical flicker fusion test of potential vision

“…[11][12][13][14][15][16] Recently, the CFF phenomenon has been suggested as a test of potential vision able to penetrate dense cataracts. [17][18][19] This is because CFF has been shown to be unaffected by the presence of cataract and other media opacities [20][21][22] as long as a bright stimulus is used 14,23 ; yet, it is sensitive to retinal and optic nerve disease. 12,[14][15][16] Moreover, as CFF reduction from retinal/neural disease correlates reasonably with visual acuity, it can be used to predict postoperative visual acuity.…”

The Effects of Central and Peripheral Refraction on Critical Fusion Frequency

“…Since both of those parameters are related at the retinal level to ocular defocus, it is surprising that CFF has been claimed to be independent of refractive error (Ong and Wong, 1971), even to the extent of uncorrected aphakia when 2-3° dia. sources are used (Havener and Henderson), 1954).…”
