OBJECTIVE: to create and validate an electronic database in ophthalmology focused on strabismus, to computerize this database in the form of a systematic data collection software named Electronic Protocol, and to incorporate this protocol into the Integrated System of Electronic Protocols (SINPE(c)). METHODS: this is a descriptive study, with the methodology divided into three phases: (1) development of a theoretical ophthalmologic database with emphasis on strabismus; (2) computerization of this theoretical ophthalmologic database using SINPE(c) and (3) interpretation of the information with demonstration of results to validate the protocol...
