Video Diversion During Fundoscopic Exam in Children (CAFE)

April 28, 2026 updated by: Ash Singhal, University of British Columbia

Video Diversion During Fundoscopic Exam in Children: A Randomized Controlled Trial

Fundoscopy is an important aspect of the neurological examination, but can be challenging in uncooperative children. This study explored whether viewing a video (selected by patient or caregiver) during eye examination improves the success, duration and ease of pediatric fundoscopy.

Hypothesis: Showing a short video clip during a fundoscopic exam will increase the probability of successfully visualizing the optic disk and reduce the amount of time needed to perform a fundoscopic exam in children between 1-8 years old.

Study Overview

Detailed Description

The purpose of this study is to examine whether showing a video clip with sound of the patient's choice can improve the ease of fundoscopic exam as defined by improved success of visualizing the optic disk and the reduction in time needed to perform the exam. The investigators will also examine the physician's and caregiver's perception on whether the video was effective in improving the ease of the exam. The purpose of the video is to capture the visual attention of the patient thereby allowing the physician to swiftly perform the fundoscopic exam. The literature has suggested that young patients are most uncooperative, therefore the investigators will focus our study on younger patients 1-8 years old.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Success rate of visualizing the optic disk within 60 seconds
Time Frame: At the time of fundoscopy exam
To determine whether showing a video clip with sound of the patient's choice can improve the success of fundoscopic exam in children as defined by the ability to visualize the optic disk within 60 seconds.
At the time of fundoscopy exam

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Reduction in the amount of time needed to visualize the optic disk.
Time Frame: At the time of fundoscopy exam
To determine whether showing a video clip with sound of the patient's choice can reduce the amount of time needed to perform a successful fundoscopic exam.
At the time of fundoscopy exam
Improvement in the physician's and caregiver's (parent/legal guardian) perception of the ease of the fundoscopic exam.
Time Frame: At the time of fundoscopy exam
Improvement in the physician's and caregiver's (parent/legal guardian) perception of the ease of the fundoscopic exam as determined by a 10 point likert scale (1 being easiest and 10 being hardest).
At the time of fundoscopy exam
