Making Chatbots more human: deep reasoning large language models in ophthalmology.

Recent advances in deep-reasoning large language models (LLMs)-including OpenAI's GPT series and open-source DeepSeek models-have expanded their potential applications in ophthalmology. In ophthalmology, image interpretation continues to rely primarily on conventional computer vision and vision language model pipelines, whereas text-based LLMs contribute to language-centric workflows, such as report interpretation, patient education drafting, and electronic health record (EHR) summarization. Multimodal systems that integrate visual inputs with reasoning have been explored in simulated or retrospective settings for tasks such as personalized planning. Although these approaches may enhance workflow efficiency and decision-making, their direct clinical benefits have not yet been established. Nevertheless, practical implementation remains challenging because of computational demands, privacy and bias considerations, and persistent issues with transparency and interpretability. Additionally, system congestion and inconsistent response times further complicate real-world clinical use. Therefore, future research should focus on addressing operational and ethical constraints, tailoring AI systems to ophthalmic workflows, and ensuring that such tools remain an assistive, equitable, and transparent partner in clinical decision-making. Thoughtful integration of deep reasoning models appears promising for ophthalmic practice, but prospective interventional studies are required before making any claims regarding patient outcomes.
