Abstract
Lid fusion was surgically performed in newly hatched and grown-up chicks for various periods of up to three-and-one-half months. This led to an unusual enlargement of the eyeball in the first group of chicks in all equators, resulting in average myopia of −8.02 D. The value that was obtained in normal eyes was +0.42 D. Simultaneously, an antagonistic procedure, although much smaller, took place, leading to flattening of the cornea and decrease of its refractive power.
Hypermetropia was found in the second group of late-operated chicks if illumination conditions were poor. This was expressed almost only in a corneal change.
In the myopic chicks the two eyes grew independently, while in the hypermetropic chicks the same change, although smaller, was found also for the open eye.
