%X OBJECTIVE: To investigate if E-learning material improves the basal student knowledge level before attending the presential class of blindness prevention (BP) and if helps to fix this information one-month after the class. METHODS: Fourth-year medical students were randomly assigned to have a presential class of BP (Traditional group = TG) or to have a presential class of BP plus an additional E-learning material (E-learning group = ELG). This material was e-mailed one week before the presential class. The students were submitted to a multiple-choice test (with three options each) with seven questions immediately before the presential class, immediately after the class, and one-month later. The three tests had the same questions; however, the answers options were distributed in different sequences. The primary outcome was immediate pretest score. The secondary outcomes were immediate posttest score and one-month posttest score. RESULTS: Among the 120 fourth-year medical students, a random sample of 34 students was assigned to the TG and 34 students was assigned to the ELG. The two groups showed similar immediate posttest score (TG=6.8 and ELG=6.9; P<.754), but the differences at the immediate pretest score (TG=3.6 and ELG=4.7; P<.001), and at the one-month posttest score, were significant (TG=6.1 and ELG=6.8; P<.001). CONCLUSIONS: The pretest and the one-month posttest results suggested that the E-learning material acts as an effective complementary tool of the presential class of blindness prevention. OBJETIVO: Avaliar se um material disponibilizado atrav谷s de E-learning antes de aulas presenciais de preven  o da cegueira (PC) melhora o n赤vel de conhecimento basal dos estudantes, e ajuda a manter esse conte迆do um m那s ap車s a aula. M谷TODOS: Estudantes do quarto ano do curso m谷dico foram aleatoriamente sorteados para ter aulas presenciais de PC (grupo tradicional = GT) ou ter aulas presenciais precedidas de material adicional por E-learning (grupo E-learning = GEL). Este material foi enviado por correio eletr nico uma semana antes da aula presencial. Os estudantes foram submetidos a testes de m迆ltipla escolha com sete quest es (com tr那s alternativas cada) imediatamente antes da aula presencial, imediatamente ap車s a aula, e um m那s ap車s a aula. Os tr那s testes tiveram as mesmas quest es: entretanto, as respostas foram distribu赤das em sequ那ncias diferentes. O desfecho prim芍rio foi a nota do pr谷-teste. Os desfechos secund芍rios foram as notas dos p車s-teste imediato e do p車s-teste tardio. RESULTADOS: Entre os 120 alunos do quarto ano de medicina, uma amostra ale
