“…Relative to P cells (approximately 80% of ganglion cells), M and K cells are large and sparse. 15,16 In certain diseases, including glaucoma, 17,18 visual dysfunction is detected more readily by tests designed to assess the function of M or K pathways than by those that assess the Eye function of P pathways. Migraineurs' visual field loss is of no exception.…”

Aims To study spatial-contrast function and short-wavelength sensitivity deficits in a migraine population with a disease duration of 30 years or less. Materials and methods In this prospective, cross-sectional study, we evaluated 28 subjects with migraine headache and 15 nonheadache healthy controls. Visual fields were evaluated using the Humphrey Field Analyzer 750i and the 30-2, blue and yellow threshold programme. Contrast sensitivity (CS) was measured at 1.5, 3, 6, 12, and 18 cpd spatial frequencies, using the Functional Acuity Contrast Test (F.A.C.T.TM ).The results of the visual field parameters (mean defect (MD) and pattern standard defect (PSD)) and CS were compared with 15 age-equivalent normal subjects.Results Short-wavelength amplitude perimetry (SWAP) parameters and CS scores at all spatial frequencies were significantly altered in the migraine patients when compared with the control subjects. Visual field parameters correlated significantly with contrast sensitivity scores: positively for MD (r ¼ 0.39, P ¼ 0.01; r ¼ 0.43, P ¼ 0.005; r ¼ 0.56, P ¼ 0.0001; r ¼ 0.45, P ¼ 0.003; r ¼ 0.48, P ¼ 0.0001) and negatively for PSD (r ¼ À0.45, P ¼ 0.003; r ¼ À0.45, P ¼ 0.003; r ¼ À0.51, P ¼ 0.001; r ¼ À0.53, P ¼ 0.0001; and r ¼ À0.67, P ¼ 0.0001) at all (1.5, 3, 6,12, and 18 cpd) spatial frequencies, respectively. Migraine duration correlated negatively with MD (r ¼ À0.42, P ¼ 0.04) and positively with PSD (r ¼ 0.42, P ¼ 0.03). Conclusion Migraineurs had significantly altered visual field and contrast function at all spatial frequencies to the normal population.These defects share some features with early stages of glaucoma and may relate a possibility for a common vascular disease pathogenesis in these two conditions.

“…This was not the case in this study. In advanced glaucomatous visual field damage, therefore, FDP measurements may also be influenced by other retinal ganglion cells [3,11,15]. In this regard, FDP may represent not only a tool for the detection of the frequency-doubling effect, but also a conventional perimetric threshold test [15].…”

“…[17][18][19][20] While the original premise for developing tasks that assess the M and K pathways is not supported by recent literature, this does not detract from the clinical utility of these tests, which have been shown to detect glaucomatous visual field loss earlier than standard white-on-white perimetry. [21][22][23][24][25][26] More recently, it has been proposed that the ability of tasks that assess M and K pathway function to more readily detect early visual field loss may arise from the minimal neural redundancy in these pathways. 27 There are far fewer M-and K-neurons than P (the retinal ganglion cell population comprises approximately 80 per cent P, 10 per cent M and five to 10 per cent K), hence M and K cells are sparsely distributed.…”

Automated perimetry has evolved substantially in recent years, in part due to modern computer technology that enables more complex visual stimuli and test procedures to be realised than those incorporated in traditional white-on-white luminance increment perimetry. This paper reviews briefly a number of advances in automated perimetry. The review includes discussion of new test types: frequency doubling technology perimetry, short wavelength automated perimetry, flicker perimetry, high-pass resolution perimetry and rarebit perimetry. Test algorithms applied to perimetry such as zippy estimation of sequential thresholds (ZEST), Swedish interactive thresholding algorithm (SITA), tendency-oriented perimetry (TOP) and multi-sampling supra-threshold perimetry are also discussed.
