title: Experimental tonography on enucleated human eyes. II. The loss of intraocular fluid caused by tonography.
abstract: In clinical work, the loss of intraocular fluid caused by tonography (dV) is usually calculated according to the formula of Grant and Friedenwald. The validity of this formula has been tested by comparing the dV calculated from known factors in the formula with the dV measured directly on enucleated eyes. Our results show a good correlation between the two methods, especially when the rigidity coefficient at the beginning of tonography is used in the calculations. It is concluded from our experiments here and in our previous paper that the theoretical foundation of tonography in principle is valid.
