Glaucoma: Transactions of the Second Conference, December 3, 4, and 5. 1956, Princeton, N. J.

The conference here reported dealt with the mechanisms of the formation of the aqueous humor, mathematical formulation of aqueous humor dynamics, mechanisms of transport by membranes, and applanation tonometry. The 25 participants gave their "off-the-cuff" opinions informally. The exchange of ideas served to promote effective communication across departmental walls which so often tend to isolate the professions and specialists from one another. Goldmann emphasized important diagnostic criteria in differentiating the findings in severe myopia and those of glaucoma in the same eye. He pointed out that when one measures the distance between the lamina cribrosa sclerae and retina above or below the papilla he finds that the distance is smaller in the glaucomatous myopic eye than it is in the normal eye—about half the normal distance: the average distance in normal eyes is 0.72 mm., and in glaucomatous myopic eyes it is 0.39 mm. His discussion of applanation tonometry is
