Early Treatment Diabetic Retinopathy Study Research Group: Photocoagulation for diabetic macular edema : ETDRS
report No 4.
demonstrated that photocoagulation reduced the risk of moderate vision loss caused by DME in about 50% of the eyes, in only 3% of eyes this therapy led to improvement of VA, and in the rest VA unfortunately remained poor due to persistence of macular edema (27,28).

Segun lo anterior, la aplicacion de la prueba piloto tuvo como objetivo evaluar el nivel de estandarizacion de las pruebas HOTV, Snellen y ETDRS
para vision lejana, en ninos de 5 a 15 anos, examinados en la Clinica de Optometria de la Universidad de La Salle.
b) Retinopathy was evaluated at visit 3 (n = 9447) and defined as an ETDRS
severity score of [greater than or equal to] 20.
These were in accordance with ETDRS

charts) and near (reduced Snellen letter charts and Jaeger's test types).

The new international grading system used in the study is a more evidence-based approach to the classification of the disease and it incorporates data found in excellent trials such as the ETDRS
and the WESDR.
