Fundamentals of spatial vision in the barn owl (Tyto alba pratincola) : ocular aberrations, grating acuity, contrast sensitivity, and vernier acuity
… have excellent optical quality. Higher-order aberrations were about 3-fold lower than has been reported in human eyes with similar methods and under comparable conditions. The spatial contrast sensitivity function (CSF) of the barn owl was measured in several psychophysical experiments with an …

Adaptive optics, aberration dynamics and accomodation control. An investigation of the properties of ocular aberrations, and their role in accomodation control.
… of two parts: a report on the use of a binocular Shack-Hartmann (SH) sensor to study the dynamic correlation of ocular aberrations; and the application of an adaptive optics (AO) system to investigate the effect of the manipulation of aberrations on the accommodation control. The binocular …

Development of Multi-modal and Super-resolved Retinal Imaging Systems
… imaging, and resolution degradation due to ocular aberrations and diffraction. </p><p>Bulky tabletop SLO and OCT systems are incapable of imaging patients that are supine, under anesthesia, or otherwise unable to maintain the required posture and fixation. Monochromatic SLO and OCT imaging …

Ocular accommodation control and adaptive optics. The development of monocular and binocular adaptive optics instrumentation for the study of accommodation and convergence, and study of the monocular accommodative response to rapid changes in dioptric stimuli.
… to studies of accommodation and higher-order ocular aberrations, which feature in the subsequent chapters. Following a brief introduction to the general technique of aberrometry and visual stimulus control using adaptive optics, the development of a monocular adaptive optics instrument for …

Visual Performance in Pseudophakia. The Effect of Meridional Blur in Pseudoaccommodation.
… size, anterior chamber depth (ACD), corneal and ocular aberrations, corneal multifocality, patient age, axial length). Further, the functionality of meridional blur was evaluated for alphabets in addition to the standard Roman alphabet using a VA task. The results confirm that myopic astigmatism …

Following Ocular Changes in United States Optometry Students (FOCUS): Protocol Development and Baseline Data
… pilot data for the longitudinal study, Following Ocular Changes in United States Optometry Students (FOCUS), which aims to collect comprehensive ocular data over two years in a population of young adults that are known to engage in intense near work. Methods: First year optometry students at the …

Influence of ocular monochromatic aberrations in the development and/or progression of myopia
… association if any, between ‘on’ and ‘off-axis’ ocular aberrations and a myopic change in refractive error using the data obtained longitudinally. Methods: On and off-axis aberrations of cyclopleged eyes (5 mm pupil diameter) of 646 children were measured during 2004-2005 (age, 12.7 ± 0.4 years) …
