[HTML][HTML] The pattern of visual deficits in amblyopia

SP McKee, DM Levi, JA Movshon - Journal of vision, 2003 - iovs.arvojournals.org
Amblyopia is usually defined as a deficit in optotype (Snellen) acuity with no detectable

Vernier acuity, crowding and amblyopia

DM Levi, SA Klein - Vision research, 1985 - Elsevier
When a vernier target is flanked by a pair of optimally positioned flanks, offset discrimination
is strongly degraded. Spatial interference with vernier acuity was studied in each eye of …

Differences in vernier discrimination for grating between strabismic and anisometropic amblyopes.

DM Levi, S Klein - Investigative Ophthalmology & Visual …, 1982 - iovs.arvojournals.org
Two gratings composed of lines were displayed one above the other, and the vernier
threshold was measured as a function of spatial frequency and vertical separation between …
