Filling-in of retinal scotomas
Vision Research, 2003 In this study we examined the perception of one- and two-dimensional patterns across central retinal scotomas, caused by age-related macular degeneration. In contrast with previous studies of disrupted visual input that used the blind spot and artificial scotomas, the current study used large central scotomas caused by physical retinal damage.

Adaptation to a simulated central scotoma during visual search training [PDF]
Vision Research, 2014 Patients with a central scotoma usually use a preferred retinal locus (PRL) consistently in daily activities. The selection process and time course of the PRL development are not well understood. We used a gaze-contingent display to simulate an isotropic

Optic Disc Morphology and Paracentral Scotoma in Patients with Open-Angle Glaucoma and Myopia
Journal of Clinical Medicine, 2023 This study’s aim was to investigate the association between optic disc morphology and the occurrence of paracentral scotoma in eyes with open-angle glaucoma (OAG) and myopia.

The effects of simulated cataract on reading with normal vision and simulated central scotoma [PDF]
Vision Research, 1999 Reading rates are slower for persons with low vision than for normally-sighted persons. This study investigated the change in reading performance and reading eye movements when we simulated the two most common causes of low vision — central field loss ...

Survey of Ophthalmology, 2019
A 54-year-old white man presented with a "blind spot" temporally in his left eye. Best-corrected visual acuity in the affected eye was 20/20, and Humphrey visual field revealed an enlarged blind spot. Funduscopic examination revealed subtle peripapillary pigmentary changes corresponding to a well-demarcated peripapillary region of hyperautofluorescence

Effect of Luminance on Scotomas
American journal of optometry and physiological optic, 1984Chez une patiente de 40 ans. Les auteurs ont constate que la decroissance de la luminance, accroissait la grandeur de son champ visuel ou diminuait celle de son scotome. Le sujet, sous forte luminance heurte occasionnellement des objets etendus. Il lui a ete recommande de porter des verres solaires sombres a l'exterieur et gris a l'interieur lorsque ...

American Journal of Psychiatry, 1973
A number of writers have advanced the opinion that it is beneficial to a patient to have a therapist of the same ethnic background. The authors point out that this may lead to "blind spots" that prevent the therapist from seeing the irrationality of certain of the patient's attitudes. They give three case examples that illustrate this point.

Survey of Ophthalmology, 2002
A 28-year-old woman presented with painful unilateral left visual loss, impaired color vision, left afferent pupillary defect, and normal ocular fundus. Although optic neuritis was first suspected, visual fields disclosed a junctional scotoma related to chiasmal demyelination, due to a probable multiple sclerosis.

IN A REVIEW of the visual field records of some 3,000 cases accumulated at the Charlotte Eye, Ear and Throat Hospital since 1928, it was observed that these included a surprising number of cases of pericentral ring scotomas.1Larger ring scotomas, of the sort familiar in retinitis pigmentosa and of the nerve fiber bundle type, appeared less frequently ...
