A Comparison between Video Bio and Standard Bio

Background: As an optometrist, one needs to be comfortable and exceptional at
binocular indirect ophthalmoscopy (BIO) to evaluate the internal health of the eye. The
purpose of this study is to compare student' s abilities to perform a dilated fundus
examination (DFE) using their own standard BIO and a provided video BIO. Methods:
Subjects will consist of 15 third year optometry students. Subjects will then be assigned
to time slots where they will perform BIO and be graded on their skills. They will first
use their own equipment with a teaching mirror on, then again with a video BIO. Both
researchers will be grading each individual then scores will be compared. Results:
Statistical analysis was done to compare participants personal BIO scores to their video
BIO scores. The difference between the two graders scores were analyzed. Participants
and graders subjective observations on the entire process were also repo1ied.
Conclusions: Participants scored much higher with the standard BIO versus the video
BIO. Grades were also much more consistent between graders with the standard BIO.
Participants were more confident in their skills and felt more comfortable using the
standard BIO.
