Experimental Amblyopia in Monkeys: I. Behavioral Studies of Stimulus Deprivation Amblyopia
TLDR
The results reveal that severe visual impairment without recovery was caused by lid closure during the first four weeks of life, and if lid closure was performed at three months or afterwards, the deprived eye showed rapid functional recovery when the lids were reopened.Abstract:
Rhesus monkeys were visually deprived unilaterally by surgical closure of the eyelids at different ages after birth. The animals were subsequently conditioned to respond to Landolt rings in different positions to determine visual acuity. After acuity thresholds were established for the nondeprived eye, it was surgically closed; the deprived eye was opened, and the acuity of the deprived eye was measured. The results reveal that severe visual impairment without recovery was caused by lid closure during the first four weeks of life. If lid closure was performed at three months or afterwards, the deprived eye showed rapid functional recovery when the lids were reopened. The electroretinograms in two monkeys with stimulus deprivation amblyopia were normal.read more

TL;DR: In this article, the authors compared the rates of retinal detachment (RD) repair and hospitalization for endophthalmitis after extracapsular cataract extraction (ECCE) in 1986 and 1987 with those following inpatient catarach extraction in 1984.

Effects of visual deprivation and strabismus on the response of neurons in the visual cortex of the monkey, including studies on the striate and prestriate cortex in the normal animal
TL;DR: The neurophysiological results demonstrated changes at the single neuron level which paralleled the degree of the behavioral changes: in animals with very poor acuity in the deprived or deviate eye (the form deprived and one esotropic animal), only a small number of neurons were driven from the operated eye; in one esotrope and the exotropic animal, which had good acuity, many neurons received an input from that eye, but only asmall number of these were binocular.

TL;DR: Eight neonates who had total, monocular, congenital cataracts with surgery, occlusion, and contact lenses were treated, and visual results in all eight patients were good.

Comparison of the effects of unilateral and bilateral eye closure on cortical unit responses in kittens

TL;DR: In these experiments the use of monocular deprivation made it possible to compare adjacent geniculate layers, and also to compare the two eyes in their ability to influence cortical cells, so that each animal acted, in a sense, as its own control.

TL;DR: Single-unit recordings in the optic tract and lateral geniculate body of kittens in which one eye had been deprived of vision are described, and an anatomical examination of the visual pathways in these animals are examined.

TL;DR: The purpose was to learn the age at which cortical cells have normal, adult-type receptive fields, and to find out whether such fields exist even in animals that have had no patterned visual stimulation.
