Abstract

The main damage in glaucoma starts at the level of the sclera, where the axons of the retinal ganglion cells forming the optic nerve fibers and retinal vessels pass through a network of connective tissue called the lamina cribrosa (LC). Modern diagnostic methods, such as optical coherence tomography, especially SD-OCT and Swept-OCT (SS-OCT), make it possible to visualize LC and determine blood flow in it, opening up new possibilities for the diagnosis of glaucoma. The review provides information about the anatomy and blood supply of the LC, as well as the latest data on the study of these structures by optical coherence tomography. Key words: primary open-angle glaucoma, lamina cribrosa, ocular blood flow, swept-source optical coherence tomography, pressure of cerebrospinal fluid
