Many eyes appear to have a dark ring at the limbus. The present work investigated whether this ring could be partly caused by optical properties of the eye near the limbus.The eyes of 10 human subjects were immersed in water, by having subjects wear

Conventional static automated perimetry provides important clinical information, but its utility is limited by considerable test–retest variability. Fixational eye movements during testing could contribute to variability. To assess this possibility

Glaucomatous damage to upper and lower retina is often unequal. We have developed a rapid, objective, quantitative measure of asymmetry of retinal sensitivity, using infrared pupillometry and pairs of large stimuli that are symmetric about the horizo

Purpose: To study the learning and reading of tactile fonts by seniors. Design: One hundred blindfolded subjects age 65 years and older were taught and studied one of three tactile fonts: a new font named ELIA, the standard Braille font, or a raised

The purpose of this study was to examine the effects of convectional flow and anterior segment configuration on drug kinetics. Mydriatics were applied focally at the limbus in order to produce sector dilation of the pupil. Subjects were tested with e

In studies of smooth eye movements, saccades are often detected and removed from eye movement records during analysis. A simple and effective method for saccade detection is described; the method uses jerk (the third derivative of eye position with r

Subjects made smooth pursuit eye movements with a target moving horizontally at 15 deg/sec. At a specified location the target either: (1) suddenly vanished; or (2) jumped to the fovea with target retinal velocity and feedback becoming 0 (target stab

Pupil shape and placement were studied during pharmacologic dilation, using a photographic technique. Dilation onset was highly asymmetric; typically, the inferior or inferior-nasal side of the pupil moved maximally, while the opposite side barely mo
