[The pathomorphological characteristics of the cataractous lens in glaucoma patients].
Lenses from patients with glaucoma and senile cataract (control) were examined under electron microscope. Ultrastructural changes in the lenses of glaucoma patients differ from changes in senile cataract by a more pronounced thinning of the capsule and development of microdefects in it and in many cases by accumulation of amorphous material on the surface of the posterior capsule adjacent to the vitreous body. This material may be pseudo-exfoliate or a manifestation of stratification of the posterior capsule proper. Development of a pseudomembrane on the surface of posterior capsule is a manifestation of proliferative processes in glaucoma. These features in a certain measure reflect the mechanism of cataract development in glaucoma, which helps plan the measures for preventing it. The status of posterior lenticular capsule in glaucoma is to be taken into consideration when implanting intraocular lenses.
