Background: Fundoscopy is an important component of the neurological examination as it can detect pathologies such as high intracranial pressure. However, the examination can be challenging in young children. This study evaluated whether playing a video during eye examination improves the success, duration, and ease of pediatric fundoscopy.
Materials and methods: This was a prospective, multipractitioner, multiclinic, randomized controlled trial. Patients aged one to four years were recruited in the emergency department, neurology clinic, spinal cord clinic, and general pediatric clinic. Eye examination was randomized to video or non-video-assisted fundoscopy. Successful examinations were defined as visualizing the fundus within 60 seconds. Time to visualize optic disc was recorded and difficulty of examination was assessed using a 10-point Likert scale.
Results: We recruited 101 subjects with a mean age of 2.8 years. Overall, there was a 20% absolute improvement in the success rate of visualizing the optic disc in the video versus non-video group (P < 0.001, 95%CI: 7.8% to 31%). Time to visualize optic disc was also improved (Δ5.3 seconds, P < 0.01, 95%CI: 1.4 to 9.1 seconds). Practitioners and caregivers noticed a 33% (P < 0.01, 95%CI: 21% to 44%) and 42% (P < 0.01, 95%CI: 30% to 56%) relative improvement in the ease of examination with video, respectively.
Conclusions: The use of videos improved the ease, duration, and, most importantly, the success of fundoscopy in younger children. This simple, inexpensive adjunct has great potential to improve the ease and efficacy of this aspect of the neurological examination and allow fundoscopic examination to be effectively performed earlier in the age-appropriate vision screening protocols.
