According to the World Health Organization, blindness is defined as visual acuity less than 3/60 (20/400) in the better eye and a visual field less than 10 ° from the central fixation point. The objective was to describe the clinical demographic characteristics of patients with a diagnosis of irreversible blindness treated at the General Ophthalmology Service of the "Clínica Belén" - "Coronel Oviedo" (Paraguay). This was an observational, descriptive and retrospective cross-sectional study. A retrospective review of the medical records of patients with a diagnosis of irreversible blindness treated at the General Ophthalmology Service of the "Clínica Belén" between February 1, 2018 and February 28, 2019 was carried out. Age, sex, education, origin, visual acuity, comorbidities and etiology of visual impairment were analyzed. The statistical analysis was through the calculation of absolute and relative frequencies, as well as the average and standard deviation. Seventy eight patients were studied, with a slight predominance of males (56.4%), aged 71 to 95 years (43.6%), incomplete primary school (41%) and from "Coronel Oviedo" (25.6 %) and surroundings. Arterial hypertension (55.6%) was the main comorbidity and glaucoma (43.6%) the most frequent blindness etiology. Glaucoma was more common in male patients than female patients (59% and 32%, respectively) and in patients older than 50 years of age (50%). In this series, patients presented bilateral irreversible blindness, more frequent in men, older than 50 years of age, hypertension as comorbidity and glaucoma as the most frequent etiology.
