ABSTRACT
Ventral decompression was evaluated as a treatment for cervical disk protrusion in large- and giant-breed dogs. All of the dogs improved after ventral decompression. After a follow-up period averaging 16 months, half of the dogs were clinically normal and the other half were functional pets despite minor residual proprioceptive deficits. Ventral decompression alone appeared to be acceptable treatment for dogs not having other radiographic signs of caudal cervical spondylopathy.

Electroretinograms (ERG) and visual evoked responses (VER) were recorded from 2 anesthetized dogs before and after surgical manipulation. The ERG was recorded from a corneal contact lens, and the VET, from 9 different scalp sites. The recordings were made on a signal averager as done in clinical situations. Surgical manipulation consisted of an alcohol block of the stimulated eye and enucleation of the nonstimulated eye. The results indicated that under the conditions of making the recordings, the major and consistent waves of the VER from all scalp sites were a far-field ERG and were not of cortical origin.
