The German Self-Help Association for Glaucoma Patients reports that glaucoma ('blue water') is a common eye disease that can lead to blindness if left untreated, as it damages the optic nerve. The association explains that the causes of glaucoma include elevated intraocular pressure, diabetes, high blood pressure, severe nearsightedness, as well as heredity and age (over 40). Symptoms indicating glaucoma include blurred vision, possibly seeing halos around lights, eye pain and redness, as well as general symptoms like severe headache, nausea, and vomiting. These symptoms should prompt an immediate doctor's visit for timely treatment, which includes eye drops and laser therapy.
