Video Diversion Improves the Success Rate of Fundoscopic Examination in Children: a Prospective Multi-clinic, Multi-practitioner, Randomized Controlled Trial

Fundoscopy is an important component of the neurological examination as it can detect pathologies such as high intracranial pressure. However, the exam can be challenging in uncooperative children. This study looked at whether playing a video during eye examination, improves the success, duration and ease of pediatric fundoscopy.

Detailed Description

Fundoscopy is an important component of the neurological examination as it can detect pathologies such as high intracranial pressure. However, the exam can be challenging in uncooperative children. This study looked at whether playing a video during eye examination, improves the success, duration and ease of pediatric fundoscopy. The authors plan to recruit from 4 different clinical care settings for a total of 101 subjects. Success rate is defined as visualizing the optic disc within 60 seconds from commencement of fundoscopy. The ease of examination is determined by using a 10 point likert scale.
