O modelo facilita o aprendizado e contribui para a formação de médicos adequadamente preparados para diagnosticar problemas que podem levarà cegueira, permitindo o rápido encaminhamento dos pacientes para os serviços especializados. Discutimos aqui alguns aspectos básicos daóptica do olho humano e do oftalmoscópio direto, bem como do seu uso. Palavras-chave:óptica, olho humano, oftalmoscópio, oftalmologia. This paper presents a simple construction model of the human eye to be used to teach the technique of direct ophthalmoscopy to medical students. The model facilitates the learning process and contributes to the training of physicians adequately prepared to diagnose problems that can lead to blindness, allowing rapid referral of patients to specialized services. Here we discuss some basic aspects of the human eye optics and direct ophthalmoscope as well as its use.

ObjectiveTo reduce the inappropriate identification of eye drops, through the use of different colors.MethodsA group of 34 healthy volunteers was presented to two groups of four eye drops each. All eye drops were placed in identical, unlabelled vials. In one group, all four eye drops were transparent. In the other group, each had a different color. A number was assigned to each eye drop, and the volunteer was asked to identify it by color. We measured the correct index in the identification of the eye drops of the two groups.ResultsThe volunteers had a level of education from incomplete junior school to complete graduate course, with 16 males (48%) and 18 females (52%), age range of 21 to 87 years. The success rate in the group of colored eye drops was 88% and, in the group of transparent, 24%.ConclusionThe use of colorings in eye drops can help distinguishing the vials and preventing misidentification.
