摘要:

Biofeedback techniques were used to alter congenital nystagmus (CN) in an albino. In response to auditory cues, the patient was able to reduce the amplitude of the nystagmus by 50% or more. In response to a combination of auditory and visual cues, the patient was able to alter the waveform of the nystagmus in such a manner that progressively larger portions of each cycle of the nystagmus were spent with the eye relatively stationary. Presumably as a consequence of this alteration in waveform, the patient's visual acuity (VA) improved from 6/35 to 6/25. The results indicate that, although VA in albinos is limited ultimately by the presence of foveal hypoplasia, other components of the typical albinotic syndrome (such as the accompanying nystagmus) can add to the acuity reduction and should, therefore, be treated.

摘要:

The refractive error observed in experimentally-induced myopia in chicks appears to occur as a result of expansion of the vitreous chamber. Fourteen days after the application of a goggle to one eye, the eye was myopic and had a greater volume of liquid vitreous than the non-myopic eye. The relative proportion of liquid to gel vitreous was also higher in the myopic eye than in the non-myopic eye. The results suggest that the vitreous humor plays a key role in the development of experimentally-induced myopia in chicks.
