ABSTRACT
Background: Retinopathy causes visual deficiency in diabetics, but is not the cause in all. Some diseases cause visual deficiency that can be reverted by therapy, but their prevalence in diabetics is unknown; as a result visual deficiency is generally thought to be secondary to retinopathy purpose: to identify the most common causes of visual deficiency in diabetics, and to compare the prevalence of retinopathy as a cause with that of other diseases.
Method: Visual function, anterior segment and ocular fundus were evaluated in diabetics. The sample was, evaluated according to four cut-points: visual acuity 20/40, visual capacity 20/40, 20/200 and 5/200. Patients were assigned to one of two groups: with visual deficiency, if their vision equalled the
cut-point and without visual deficiency, if it was better. The cause of visual deficiency was identified in each patient. Visual deficiency was compared in patients with and without diabetic retinopathy.
Results: 776 patients were evaluated; 128 (16.4%) had retinopathy. The most common
cause of visual deficiency in every cut point was cataract, followed by ammetropia; both diseases were more frequent than retinopathy as a cause of visual deficiency in the cut points of visual acuity 20/40 and visual capacity 20/40, but not in the points visual capacity 20/200 and visual capacity 5/200.
Discussion: The most frequent cause of visual loss in diabetics is not
retinopathy. The most common problems cause a reversible visual loss. It is suggested that every patient should be referred for ophthalmic evaluation, whether visual loss is present or not.
