Bouma's law of crowding predicts an uncrowded central window through which we can read
and a crowded periphery through which we cannot. The old discovery that readers make …

Several definitions, measurements, and implicit meanings of 'fixation stability'have been
used in clinical vision research, leading to some confusion. One definition concerns eye …

Purpose.: There is a need for standardized texts to assess reading performance, for multiple
equivalent texts for repeated measurements, and for texts equated across languages for …

Background Recent evidence suggests that amblyopia results in fixation instability and
atypical saccades. Reading is a vision-reliant ability that requires sequential eye …

The central region of the human retina, the fovea, provides high-acuity vision. The
oculomotor system continually brings targets of interest into the fovea via ballistic eye …

Purpose: The Nidek microperimeter (MP1, Nidek Instruments, Italy) is a microperimetry
device that also assesses fixation stability. The MP1 does not use the method of quantifying …

Background Previous studies show slow reading in strabismic amblyopia. We recently
identified amblyopia, not strabismus, as the key factor in slow reading in children. No studies …

Crowding refers to impaired target recognition caused by surrounding contours. We
investigated the development of crowding in central vision by comparing single-letter and …

Background Age-related macular degeneration (AMD) causes reading impairment, reduced
quality of life (QoL), and secondary depression. We have shown that support with …

Amblyopia is a neurodevelopmental disorder caused by abnormal visual experience in early
life that affects 3–5% of the population. Amblyopia results in a host of monocular and …
