Medical Accuracy of Reddit in Patient Discussions of Prospective Ocular Stem Cell Therapies for Retinal Degenerative Diseases.

To evaluate the medical accuracy in discussions of stem cell therapy for retinal diseases on a social media internet forum (Reddit). A cross-sectional study assessed 11 Reddit forums and 411 unique comments from 2017 to 2022. Evaluated participants were all anonymous Reddit users. Discussions were independently examined for medical accuracy by a board-certified, fellowship-trained retina surgeon in active practice. Reddit users self-identified mainly as prospective patients followed by research students and physicians or healthcare workers. Inquiries mostly regarded stem cell treatment for macular degeneration. Thirty-six percent of the forum's content was found to be inaccurate or misleading. When specifically considering factual comments, the inaccuracy rate increased to 54%. Identified gaps in knowledge mostly regarded the current state of the technology (25%) followed by misinterpretation of trial results (16%) and scam treatments (14%). Most inaccurate or misleading comments favored stem cell advancements (72%). This study highlights the gaps in knowledge and areas of medical misinformation regarding ocular stem cell therapies shared by individuals on Reddit.
