Abstract

Retinal and tectal potentials to alternating gratings were recorded in pigeons raised monocularly deprived. Deprived eyes showed consistent myopia and anterior-posterior axis elongation. In addition, vitreal opacities were observed in 70% of the deprived eyes. In pigeons with vitreal opacities, a reduction of retinal and tectal response amplitude was consistently found in the high spatial frequency range. Pigeons with clear media of the deprived eyes showed normal retinal and tectal responses.

摘要

在单眼剥夺饲养的鸽子中记录了视网膜和视顶盖对交替光栅的电位。剥夺眼表现出一致的近视和前后轴伸长。此外，在70%的剥夺眼中观察到玻璃体混浊。在有玻璃体混浊的鸽子中，在高空间频率范围内始终发现视网膜和视顶盖反应幅度降低。剥夺眼介质清晰的鸽子表现出正常的视网膜和视顶盖反应。
