Shen C, et al. - Via a vignette-based, cross-sectional study of 42 validated clinical vignettes of ophthalmic symptoms between October 15, 2017, and April 30, 2018, experts discovered the accuracy of the most popular online symptom checker for ophthalmic diagnoses. Eleven out of had a true primary diagnosis generated by the symptom checker. In 16 of 42 cases, the accurate diagnosis was involved in the online symptom checker's top 3 diagnoses. The right diagnosis was not involved in the symptom checker's list in 18 of 42 cases. In 7 of 18 emergent cases and 21 of 24 nonemergent cases, triage urgency based on the top diagnosis was found to be relevant. Interuser variability for the accurate diagnosis being in the top 3 listed was observed to be at least moderate. Hence, the most popular online symptom checker could reach at the correct clinical diagnosis for ophthalmic conditions, however, a substantial proportion of diagnoses may not be seized. Further research is needed, nonetheless, in order to reveal the real-life utilization of internet diagnostic resources.
