The relationship of the hyaluronidase and antihyaluronidase activity of the retina to the intensity of a light stimulus

The retina possesses hyaluronidasic and antihyaluronidasic activity which depends on the strength of the light stimulus. In prolonged continuous light stimulation the retinal hyaluronidasic activity is diminished. The dynamics of decrease of the hyaluronidasic activity depends on its initial value: the higher the initial activity, the quicker its decrease.
