Insights
Playing videos during fundoscopy significantly improves success rates and reduces examination time in young children. This simple technique enhances pediatric neurological exams and early vision screening.
Area of Science:
- Pediatric Neurology
- Ophthalmology
- Clinical Trial Methodology
Background:
- Fundoscopy is crucial for detecting neurological conditions like high intracranial pressure.
- Pediatric fundoscopy is often challenging due to patient cooperation.
- This study investigates video-assisted fundoscopy in young children.
Purpose of the Study:
- To evaluate the impact of video playback on the success rate, duration, and ease of pediatric fundoscopy.
- To determine if video assistance improves the diagnostic yield of fundoscopic examinations in children aged 1-4 years.
- To assess the feasibility of integrating video aids into routine pediatric neurological assessments.
Main Methods:
- A prospective, randomized controlled trial involving 101 children aged 1-4 years.
- Comparison of video-assisted versus non-video-assisted fundoscopy.
- Key metrics included success rate (fundus visualization within 60 seconds), time to visualize the optic disc, and perceived difficulty on a 10-point Likert scale.
Main Results:
- A 20% absolute improvement in successful fundus visualization with video assistance (P < 0.001).
- Reduced time to visualize the optic disc by an average of 5.3 seconds (P < 0.01).
- Significant improvements in ease of examination reported by practitioners (33%) and caregivers (42%) with video use (P < 0.01).
Conclusions:
- Video assistance substantially enhances the success, efficiency, and ease of fundoscopy in young children.
- This inexpensive adjunct can improve the efficacy of neurological examinations and facilitate earlier vision screening.
- Video-assisted fundoscopy offers a practical solution for overcoming challenges in pediatric eye assessments.
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.
