• Specimens cut in cross section at the level of the lamina cribrosa in normal primate eyes are examined by light microscopy. The density of structural elements, consisting of crosswise-oriented connective-tissue trabeculae, is examined in different regions of the nerve head. It is noted that nasal more than temporal more than superior or inferior regions of the lamina cross section contain increased connective-tissue elements. This regional variation in nerve head anatomy is contrasted with susceptibility patterns of nerve head tissue to pressure elevation in both experimental and clinical glaucoma.
