COMMUNICATIONS ANATOMICAL STUDIIES OF THE TRABECULAR MESHWORK OF TILE NORMAL HUMAN EYE* BY

IN recent years increasing evidence has been obtained of an abnormal re-sistance to aqueous outflow in eyes affected with chronic simple glaucoma; it now appears essential to determine to what extent this may be attributable to structural changes and at which particular site or sites in the drainage area the impediment is located. In this problem, consideration of the trabecular meshwork is clearly of primary importance, but a true assessment of morbid anatomical changes and their distinction from appearances due to artefact can be based only upon an accurate knowledge of normal structure. Al-though many anatomical studies of the trabecular meshwork are available both in. papers and textbooks, they are frequently deficient in detail and differ from each other in important respects. As a preliminary to future work on pathological material, we have therefore thought it necessary to sununarize existing knowledge and to carry out, by old and new methods, a further anatomical study of this region.
