Alkali and acid burns of the rabbit eye: measurement of aqueous flow by means of intravenously injected Na-125 I and Na-131I.

Rabbit eyes were burned either with 1N NaOH or 1 N HC1. On the fifth day following the injury, aqueous humour flow was determined according to a method originally described by Becker (1962), using intravenous injection of Na-125I and Na-131I in different time intervals. In alkali-burned eyes the main finding was stoppage of the aqueous humour flow, probably due to obstruction of outflow channels. In acid-burned eyes the significantly elevated diffusion out of the eye was probably caused by altered function of the highly irritated and hyperemic iris. Results confirmed the previous findings achieved by the rate of disappearence of 14-C-glucose injected into the anterior chamber of the burned eyes.
