It has been suggested that ambient lighting at night influences eye growth and might play a causal role in human myopia. To test this hypothesis, we reared newly hatched chicks under 12 hr light-dark or light-dim cycles with a light phase intensity o

Proper refractive eye growth depends on several features of the visual image and requisite retinal pathways. In this study, we determined the contribution of rod pathways to normal refractive development and form deprivation (FD) myopia by testing Gn

Corneal surface area and perimeter were assessed as novel indices to monitor anterior segment growth, using chicks reared under different photoperiods. We obtained central and mid-peripheral corneal curvatures using photokeratometry. Anatomical traci

Background: The precise and rapid measurement ofeye length and eye shape isessential for investigating eye growth regulation andmyopia. For this purpose, we developedan optical low coherence reflectometer (OLCR) andpresent preliminary measurements.Me

Depriving the eyes of neonatal animals of form vision induces axial eye elongation and ipsilateral myopia. We studied one-year-old chickens, an age at which full body growth has been attained, to learn if form deprivation myopia can develop at a late

Purpose. Laser Doppler interferometry (LDI) permits the measurement of intraocular distances to a precision of better than 20 microm. The signal complex from the posterior segment of the eye consists of four peaks in the chick, an animal frequently u

Myopia is a significant healthcare burden, affecting 41.5 % of the adult population in the United States 1 and greater than 80% of children aged 16–18 years in countries such as Taiwan2 and Singapore3–4. Most juvenile-onset myopia in children and

Purpose. Retinal steepness at the posterior pole was shown to be associated with peripheral refraction, and there exists strong evidence that peripheral refraction influences central refractive development. The purpose of this study was to investigat

A laser Doppler interferometer was built for the precise measurement of intraocular optical distances in humans and chicks. A technique using Purkinje images was developed to position the chick's eye reproducibly. A computer algorithm for the objecti
