Fine structure of trabecular meshwork and iris in pigmentary glaucoma. 1981

T Shimizu, and K Hara, and R Futa

Trabecular meshwork and iris were studied by light and electron microscopy in a 40-year-old female with pigmentary glaucoma. Elevation of the intraocular pressure was most likely due to closure the intertrabecular space by pigment granules and large cells resembling clump cells, fibrous substances, and hypertrophied endothelial cells of the trabecular sheet, which had phagocytized pigment granules.

UI MeSH Term Description Entries
D007498 Iris The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.

D005901 Glaucoma An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
