A tape/slide course in ophthalmology was used for fifth year medical students at the University of Edinburgh. A statistical comparison between the tape/slide and lecture method of teaching showed no significant difference in examination results: means mark (P greater than 0-50), spread of mark (P greater than 0-05), or in question consistency (P greater than 0-40). The tape/slide method is initially time consuming to produce but has clear advantages in the long term, being of a consistently high standard, easy to present and repeat, useful in revision, for student electives and in lecturers' absence.
