Resumen


Introduction: Diabetic retinopathy is a chronic microangiopathic complication characterized by an alteration of the retina vasculature; it represents a risk for visual loss or blindness; this risk can be reduced with stable metabolic control, early detection and adequate treatment. The general objective of the study is to determine the relationship between persistent hyperglycemia and diabetic retinopathy.

Methods: An observational, cross-sectional, prospective and analytical study was conducted in diabetic patients of Veracruz city, in the period between February and May 2018. Laboratory tests (HbA1c and blood glucose), visual acuity examination and fundus identification of the presence of microaneurysms, exudates, hemorrhages and neoformations were performed; subsequently, proliferative and non-proliferative diabetic retinopathy was evaluated in both eyes

Results: In the control and monitoring of glucose, group I presented 202.63 ± 65.75 mg / dl and group II 143.55 ± 50.76 mg / dl. HbAIc in group I was 10.11 ± 2.5% and group 2, 8.07 ± 2.3% (p <0.001). Hemorrhage occurred in 9 of the patients (30%) with diabetic retinopathy in the right eye, as well as Neoformations in 6 patients (20%); in the left eye hemorrhages and exudates predominated in 10 patients (33.3%) as well as neoformations in 5 of them (16.7%). The correlation of the findings of patients with diabetic retinopathy and HbAIc in the right eye was r = .3296 and in the left eye r = .4306.

Conclusions: A moderately positive relationship was found between HbA1c levels and changes suggestive of RD.

Key words: Diabetic retinopathy, hyperglycemia, type 2 diabetes mellitus
