Age-related macular degeneration, often called AMD, usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina. It occurs in âdryâ and âwetâ forms, and is a major cause of blindness and visual impairment in adults over 50 years of age.
RESULTS: Fifty-six of 290 patients progressed to legal blindness in at least one eye over the 34-year period of the study. Most who progressed to blindness had moderate to advanced visual field loss at the time of diagnosis of glaucoma.Those becoming legally blind had mean intraocular pressures (IOP) on therapy lower than or similar to patients who did not go blind, although the variability of IOP was higher in the blind group.lindness and glaucoma: a comparison of patients progressing to blindness from glaucoma with patients maintaining vision.
