| dc.description | Non-proliferative diabetic retinopathy is the earliest stage where microaneurysms appear, which is when the blood vessels are damaged and allow the flow of blood fluid into the eye. The application of an optometric examination in patients with nonproliferative diabetic retinopathy is essential, currently the Snellen test is used for evaluation. The objective was to analyze the correlation of the Snellen and ETDRS optotype in patients with non-proliferative diabetic retinopathy in an ophthalmological clinic, Teófilo Dávila Hospital, Machala, El Oro, October 2019 - March 2020. This is a quantitative approach methodology, see the method of observation, the study variables were not manipulated, the medical records were observed with real data. The female sex predominates with 60%, the age range was 66 to 70 years, 34% of the patients are housewives, the family pathological history has a higher rate with 52%, the diagnosis time was more Five years, with 54%, 71% have a moderate level of the disease. 70 eyes (35 patients) equivalent to 100%, left eye and right eye with the Snellen and ETDRS optotypes were analyzed, the group with good vision achieved a visual acuity from 20/20 to 20/50 (55%), intermediate vision 15% (20/50 to 20/200) and poor vision (20/400) 30%, differences were found between the Snellen and ETDRS optotypes. He concludes that visual acuity was significantly better in the ETDRS chart than Snellen. | es_ES |

| dc.description.abstract | La retinopatía diabética no proliferativa es la etapa más temprana donde aparecen los microaneurismas, que es cuando los vasos sanguíneos se encuentran deteriorados y permiten la salida de fluido de sangre dentro del ojo. La aplicación de un examen optométrico en pacientes con retinopatía diabética no proliferativa es indispensable, actualmente para su evaluación se utiliza el test de Snellen. El objetivo fue analizar la correlación del optotipo Snellen y ETDRS en pacientes con retinopatía diabética no proliferativa en consulta oftalmológica, Hospital Teófilo Dávila, Machala, El Oro, Octubre 2019 - Marzo 2020. Se utilizó una metodología de enfoque cuantitativo, se utilizó el método de observación, no se manipularon las variables de estudio, se observaron las historias clínicas con datos reales. El sexo femenino predomina con el 60%, el rango de edad fue de 66 a 70 años, el 34% de los pacientes son amas de casas, el antecedente patológico familiar presenta mayor índice con el 52%, el tiempo de diagnóstico fue hace más de cinco año, con el 54%, el 71% presentan un nivel moderado de la enfermedad. Se analizaron 70 ojos (35 pacientes) equivalente al 100%, ojo izquierdo y ojo derecho con los optotipos Snellen y ETDRS, el grupo con buena visión alcanzaron una agudeza visual de 20/20 a 20/50 (55%), visión intermedia el 15% (20/50 a 20/200) y visión deficiente (20/400) el 30%, se encontraron diferencias entre los optotipos Snellen y ETDRS. Concluye que la agudeza visual fue significativamente mejor en el gráfico ETDRS que el Snellen. | es_ES |
