Fusion of the Pupil

Pupillary occlusion is a condition in which the pupil closes completely or partially and stops responding to changes in light levels. Depending on the degree of pathology, part of the periphery or the entire content of the pupil is lost. This disease can be caused by various reasons.

The patency of the pupil is ensured not only by the muscles and subshin fiber of the lens, but also by the protective membranes contained in the epithelium of the iris. When exposed externally, the functional surface of the pupil is damaged, which leads to a decrease in the ability to adequately respond to changing lighting.

The outer protective layer of the eye, the iris membrane, is present in all mammals and, together with the cornea and sclera, forms the anterior segment of the eyeball. It is located between the irises, the anterior posterior (nutritional membrane and the main vessels
