In a latest research revealed within the journal Eye, researchers from Canada evaluated the efficiency of two synthetic intelligence (AI) chatbots, Google Gemini and Bard, within the ophthalmology board examination.
They discovered that each the instruments achieved acceptable accuracy within the solutions and carried out nicely within the discipline of ophthalmology, with some variation throughout nations.

Background
AI chatbots reminiscent of ChatGPT (quick for chat-generative pre-trained transformer), Bard, and Gemini are more and more utilized in medical settings. Their efficiency continues to evolve throughout exams and disciplines.
Whereas ChatGPT-3.5’s accuracy was as much as 64% in steps one and two of the AMBOSS and NBME (quick for Nationwide Board Medical Examination) exams, newer variations like ChatGPT-4 confirmed improved efficiency.
Google’s Bard and Gemini supply responses primarily based on numerous cultural and linguistic coaching, probably tailoring info to particular nations. Nevertheless, the responses differ throughout geographies, calling for additional analysis to make sure consistency, significantly in medical functions the place accuracy is essential for affected person security.
Within the current research, researchers aimed to guage the efficiency of Google Gemini and Bard on a set of observe questions designed for the ophthalmology board certification examination.
Concerning the research
The efficiency of Google Gemini and Bard was assessed utilizing 150 text-based multiple-choice questions obtained from “EyeQuiz,” an academic platform for medical professionals specializing in ophthalmology.
The portal gives observe questions for varied exams, together with the Ophthalmic Information Evaluation Program (OKAP), nationwide board exams such because the American Board of Ophthalmology (ABO) examination, in addition to sure postgraduate exams.
The questions had been categorized manually, and information had been collected utilizing the Bard and Gemini variations accessible as of 30th November and 28th December 2023, respectively. The accuracy, provision of explanations, response time, and query size had been assessed for each instruments.
Secondary analyses included evaluating the efficiency in nations aside from the US (US), together with Vietnam, Brazil, and the Netherlands, utilizing digital non-public networks (VPNs).
Statistical exams, together with the chi-square and Mann-Whitney U exams, had been performed to match efficiency throughout nations and chatbot fashions. Multivariable logistic regression was used to discover components influencing right responses.
Outcomes and dialogue
Bard and Gemini responded promptly and persistently to all 150 questions with out experiencing excessive demand. Within the main evaluation utilizing the US variations, Bard took 7.1 ± 2.7 seconds to reply, whereas Gemini responded in 7.1 ± 2.8 seconds, with an extended common response size.
Within the main evaluation utilizing the US type of the chatbots, each Bard and Gemini achieved an accuracy of 71%, appropriately answering 106 out of 150 questions. Bard offered explanations for 86% of its responses, whereas Gemini offered explanations for all responses.
Bard was discovered to carry out finest in orbital & cosmetic surgery, whereas Gemini confirmed superior efficiency basically ophthalmology, orbital & cosmetic surgery, glaucoma, and uveitis. Nevertheless, each the instruments struggled within the cataract & lenses and refractive surgical procedure classes.
Within the secondary evaluation with Bard from Vietnam, the chatbot answered 67% of questions appropriately, much like the US model. Nevertheless, utilizing Bard from Vietnam led to totally different reply decisions in 21% of questions in comparison with the US model.
With Gemini from Vietnam, 74% of questions had been answered appropriately, much like the US model, however there have been variations in reply decisions for 15% of questions in comparison with the US model. In each circumstances, some questions answered incorrectly by the US variations had been answered appropriately by the Vietnam variations, and vice versa.
The Vietnam variations of Bard and Gemini defined 86% and 100% of their responses, respectively. Bard carried out finest in retina & vitreous and orbital & cosmetic surgery (80% accuracy), whereas Gemini carried out higher in cornea & exterior illness, basic ophthalmology, and glaucoma (87% accuracy every).
Bard struggled most in cataracts & lenses (40% accuracy), whereas Gemini confronted challenges in pediatric ophthalmology & strabismus (60% accuracy). Gemini’s efficiency in Brazil and the Netherlands was comparatively inferior to the US and Vietnam variations.
Regardless of the promising findings, the research’s limitations embrace a small query pattern dimension, reliance on an brazenly accessible query financial institution, unexplored results of consumer prompts, web pace, web site site visitors on response occasions, and occasional incorrect explanations offered by the chatbots.
Future research might discover the chatbots’ capability to interpret ophthalmic photographs, which stays comparatively unexplored. Additional analysis is warranted to handle the constraints and discover further functions within the discipline.
Conclusion
In conclusion, though each the US and Vietnam iterations of Bard and Gemini demonstrated passable efficiency on ophthalmology observe questions, the research highlights potential response variability linked to consumer location.
Future evaluations to trace the enhancement of AI chatbots and comparisons between ophthalmology residents and AI chatbots might supply worthwhile insights into their efficacy and reliability.
