“…After that, many studies are present in the literature indicating a relationship between glaucoma and migraine either as a cause or a factor for progression. 1,2,[19][20][21][22][23][24][25][26][27] Recently, visual field abnormalities of migraine patients in SWAP testing was further analysed by us and we found that 53.3% of migraine patients had abnormal glaucoma hemifield tests, which is highly specific to glaucoma disease. …”

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.

“…The visual field tests were performed using the C30-2 program of Humphrey visual field analyser, Model 750 (Zeiss Inc, San Leandro, CA, USA) or Model 630 (Allergan Inc, San Leandro, CA, USA). We defined NTG according to the following criteria: (1) intraocular pressure consistently less than 21 mm Hg in an eye without antiglaucoma medication, (2) characteristic glaucomatous optic nerve head damage, (3) glaucomatous visual field loss, (4) no neuroradiological evidence of optic nerve damage, (5) open iridocorneal angle, and no abnormal chamber angle structure on gonioscopic examination. POAG was defined to meet the same criteria of NTG except for intraocular pressure greater than 21 mm Hg in an eye without antiglaucoma medication.…”

“…Among the evidence supporting this theory were the different patterns of visual field defect [1][2][3][4][5] and optic nerve head configuration. 3 5-9 The frequent occurrence of optic disc haemorrhage and the high incidence of systemic diseases [10][11][12][13][14] in patients with NTG also suggested that a damaging mechanism other than high intraocular pressure contributed to the glaucomatous damage.…”

Aim: To compare the pattern of localised nerve fibre layer (NFL) defects in normal tension glaucoma (NTG) and primary open angle glaucoma (POAG). Methods: 50 NTG eyes and 36 POAG eyes, all with localised NFL defects, were enrolled. On retinal NFL photography, the proximity of the defect to the centre of the fovea (angle α) and the sum of the angular width of the defects (angle β) were determined. Angle α was the angle made by a line from the centre of the fovea to the disc centre and a line from the disc centre to the disc margin, where the nearest border of the defect met. The patterns of localised NFL defects in NTG and POAG were compared with angles α and β. Independent t test was used for statistical analysis. Results: Angle α in NTG (35.1 (SD 20.0)°) was significantly smaller than that of POAG (45.9 (21.9)°) (p=0.02), while angle β in NTG (49.0 (31.9)°) was significantly larger than that of POAG (33.1 (23.9)°) (p=0.01). Conclusions: The pattern of NFL defects in NTG was different from that in POAG. Localised NFL defects in NTG were closer to the fovea and wider in width than those in POAG.

“…In its clinical appearance, NTG almost perfectly mimics primary openangle glaucoma (POAG): normal angles on gonioscopy, cupping of the optic nerve, and visual field loss correlated with cupping that shows the progressive damage of the optic nerve [1]. In East Asia, NTG seems to be more frequent than POAG with high IOP [2] and it is certainly the most common form of glaucoma in Japan [3].…”
