Ocular pathogenicity of herpes simplex virus.

As a relatively small, discrete organ that contains a number of widely different cell types the eye provides an intriguing system in which to study fundamental aspects of virus/cell interactions. Such aspects are considered with particular reference to herpes simplex virus and the pivotal role of virus/neuron interactions in the development of ocular disease. Three aspects of this interaction are discussed: the entry of virus into the eye latency in the trigeminal ganglion nerve damage.
