Optical Aberrations of Guinea Pig Eyes

Ascorbate transport in guinea pig eyes

Excised guinea pig ciliary body-iris preparations accumulated <C-labeled L-ascorbate. The concentrating mechanism required glucose as well as Na+, K+, and Ca++ ions in the media and is inhibited by ouabain, dinitrophenol, iodoacetate, cyanide, fluoride, desoxycorticosterone, and hydrocortisone. It demonstrates saturation kinetics with increasing concentrations of Lascorbate in the media and is ...

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

Optical coherence tomography and histologic measurements of retinal and choroidal thicknesses in guinea pig eyes

Background: The purpose of this study was to evaluate optical coherence tomography and histologic measurements of retinal and choroidal thicknesses in guinea pig eyes, and assess the relationships between those thicknesses with spherical equivalent and axial length. Methods: Twelve tri-colored guinea pigs, aged from 5 to 6 weeks, were collected. Spherical equivalent (SE) was measured with a str...

Standards for reporting the optical aberrations of eyes.

In response to a perceived need in the vision community, an OSA taskforce was formed at the 1999 topical meeting on vision science and its applications (VSIA-99) and charged with developing consensus recommendations on definitions, conventions, and standards for reporting of optical aberrations of human eyes. Progress reports were presented at the 1999 OSA annual meeting and at VSIA-2000 by the...
