[Electronmicroscopic studies of the trabecular meshwork in corticosteroid glaucoma].

The tissue specimen of a 41-year-old patient with cortisonglaucoma, obtained by trabeculectomy, was examined by electronmicroscope. There are massive depositions of band-like and linear arranged structures in the cribriform area and adjacent lamellae of the trabeculum corneosclerale. The pathways for aqueous humor of this region are almost completely obstructed by this material. That is the reason for an increased outflow resistance. The cells of this area show signs of degeneration and are reduced in their numbers. -- The cortisonglaucoma differs from all the other forms of glaucoma especially from glaucoma simplex by these characteristic deposits.
