I. Etiology and Classification of Glaucoma.

Abstract:--

Etiologic factors include: obstruction of lymph spaces, especially the
angle of the anterior chamber; blood pressure, arterial, capillary and
venous; affinity of tissues for fluids; alterations of the intra-ocular
fluids; inflammations in the eye ball; and failure of a nerve apparatus
to control fluid in the globe. Classification: various types of glaucoma
constituting clinical entities must be recognised, as: simple glaucoma,
recurring exacerbations, congestive, mechanical, and increased tension
arising during uveal inflammations.
