Chat Generative Pre-trained Transformer (ChatGPT) was used to classify deidentified EHR anterior chamber examination text into HE categories (no hyphema, microhyphema, clot, and hyphema). Agreement between classifications by ChatGPT and a glaucoma specialist was evaluated using Cohen’s Kappa and precision-recall (PR) curve. Time to resolution of HEs was assessed using Cox proportional-hazards models. Goniotomy HE resolution was evaluated by degree of angle treatment (90°–179°, 180°–269°, 270°–360°). Logistic regression was used to identify HE risk factors.</p></div><div><h3>Main Outcome Measures</h3><p>Accuracy of ChatGPT HE classification and incidence and resolution of HEs.</p></div><div><h3>Results</h3><p>The study included 434 goniotomy eyes (368 patients) and 528 Schlemm’s canal stent (SCS) eyes (390 patients). Chat Generative Pre-trained Transformer facilitated excellent HE classification (Cohen’s kappa 0.93, area under PR curve 0.968). Using ChatGPT classifications, at postoperative day 1, HEs occurred in 67.8% of goniotomy and 25.2% of SCS eyes (<em>P</em> &lt; 0.001). The 270° to 360° goniotomy group had the highest HE rate (84.0%, <em>P</em> &lt; 0.001). At postoperative week 1, HEs were observed in 43.4% and 11.3% of goniotomy and SCS eyes, respectively (<em>P</em> &lt; 0.001). By postoperative month 1, HE rates were 13.3% and 1.3% among goniotomy and SCS eyes, respectively (<em>P</em> &lt; 0.001). Time to HE resolution differed between the goniotomy angle groups (log-rank <em>P</em> = 0.034); median time to resolution was 10, 10, and 15 days for the 90° to 179°, 180° to 269°, and 270° to 360° groups, respectively. Risk factor analysis demonstrated greater goniotomy angle was the only significant predictor of HEs (odds ratio for 270°–360°: 4.08, <em>P</em> &lt; 0.001).</p></div><div><h3>Conclusions</h3><p>Large language models can be effectively used to classify longitudinal EHR free-text examination data with high accuracy, highlighting a promising direction for future LLM-assisted research and clinical decision support. Hemorrhagic events are relatively common self-resolving complications that occur more often in goniotomy cases and with larger goniotomy treatments.
