International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Progressive retinal ganglion cell death and visual field loss are associated with these changes. Anterior chamber angle appearance is normal and major risk factors include level of intraocular pressure and older age.
