“…The most common symptoms are blurring of vision, usually unilateral and which is perceived as a scotoma in the center of the field of vision with associated metamorphopsia and micropsia. …”

“…One month later, the optic disc swelling disappeared and BCVA improved to 20/100; however, the central scotoma remained and no further improvement in visual function OD was obtained. …”

“…Electrodiagnostic tests and optical coherence tomography provided structure–function evidence of bilateral retinal ganglion cell dysfunction and notably revealed severe loss of temporal fibres in the left eye which showed cecocentral scotoma but normal visual acuity. Although selective damage of the papillomacular bundle has been well-documented in nutritional and toxic optic neuropathies, compressive optic canal hyperostosis secondary to nutritional deficiency has been rarely reported. …”

“…The classical “Trigger happy” visual field has increased fixation loss, very high threshold retinal sensitivity with the values in supernormal range, “white scotoma” on grayscale map, high positive mean deviation (MD), glaucoma hemifield test (GHT) gives classification of “abnormally high sensitivity, ‘Excessive high false positive’ message is displayed,” and pattern deviation probability plot has more defects than total deviation probability plot known as “reverse cataract pattern.” …”

“…Electrophysiology recordings of multi-unit activity corroborated the BOLD observations: visually driven multi-unit responses could be elicited inside the V2 LPZ, even when the visual stimulus was entirely contained within the scotoma induced by the V1 lesion. Restricting the stimulus to the intact visual hemi-field produced no significant BOLD modulation inside the V2, V3 LPZs. …”

“…CONCLUSIONS: The most common pattern of progression in glaucomatous visual fields is combined progression in depth and size of an existing scotoma. Applying individually condensed test grids remarkably enhances the detection rate of glaucomatous visual field deterioration (at the expense of an increased examination time) compared to conventional stimulus arrangements.…”

“…Standard flash electroretinography showed an extinguished electroretinogram and Goldmann kinetic perimetry detected a relative scotoma. Genetic analysis revealed that the patient had a heterozygous mutation in the CYP4V2 gene (IVS6-8delTCATACAGGTCATCGCG/GC), which is the most commonly found mutation in Japanese patients with BCD. …”
