Abstract
Objective: to characterize the clinical and socio-demographical characteristics of a population of patients with visual impairment attended at two health institutions in Medellín (Antioquia, Colombia), with an emphasis on the etiology of irreversible vision loss.
Methodology: Observational, descriptive study of unilateral and bilateral visual impairment in 1 742 medical records to identify patients with low vision or blindness. A research form was used to validate patients with visual impairment, and 107 medical records were selected.
Results: 56.6% presented low vision and 43.4% presented blindness. Vision loss was due to ophthalmic causes in 39% of cases, 20% were caused by neuro-ophthalmic alterations and 17% by neurological disorders of the visual cortex. In addition to visual acuity, other visual impairments were found, such as optic atrophy, electrophysiological alteration of the visual pathway, and encephalomalacia in visual cortices. 82% of patients had at least one nonophthalmic comorbidity.
Conclusions: Adequate registration of rehabilitation activity, biological, social, and psychological characteristics of patients with low vision and blindness is essential in order to fully understand both the impairment and its impact.
