Abstract
Purpose: The purpose of this study was to cut down on screening time and costs, this study optimizes field-of-view (FOV) combinations for classifying type-1 retinopathy of prematurity (ROP) through multiple-instance learning (MIL) that models clinical decision making.
Methods: The dataset included 1420 photographs of 284 eyes (204 eyes from Chang Gung Memorial Hospital [CGMH] and 80 eyes from Osaka University), each eye containing five FOVs (temporal, nasal, central, superior, and inferior). We evaluated various FOV combinations and compared two MIL fusion strategies, feature-level and outcome-level, to identify the most effective approach. Feature-level learns a joint representation across views, whereas outcome-level aggregates the predicted probabilities from each view at the decision stage. Model performance was evaluated using five-fold cross-validation, with metrics including accuracy, precision, recall, F1-score, and area under the curve (AUC).
Results: The feature-level MIL significantly outperformed the outcome-level MIL in all combinations and metrics except the superior view (P < 0.05). Among FOV combinations, the temporal, nasal, and central set achieved the highest performance (accuracy = 0.892 ± 0.043, F1-score = 0.831 ± 0.097). Horizontal (temporal and nasal) and central views individually showed stronger diagnostic power, comparable to multi-view settings, whereas vertical (superior and inferior) views performed significantly worse.
Conclusions: The feature-level MIL model effectively simulates clinical decision making for type-1 ROP classification. Temporal, nasal, and central views, as well as their combination, achieved superior performance over vertical views or their combination. Notably, feature-level MIL outperformed outcome-level MIL, underscoring the critical role of information fusion strategy.
Translational relevance: Clinically aligned MIL with optimized FOV selection enables more efficient artificial intelligence (AI)-assisted telemedicine screening for retinopathy of prematurity.
期刊介绍:
Translational Vision Science & Technology (TVST), an official journal of the Association for Research in Vision and Ophthalmology (ARVO), an international organization whose purpose is to advance research worldwide into understanding the visual system and preventing, treating and curing its disorders, is an online, open access, peer-reviewed journal emphasizing multidisciplinary research that bridges the gap between basic research and clinical care. A highly qualified and diverse group of Associate Editors and Editorial Board Members is led by Editor-in-Chief Marco Zarbin, MD, PhD, FARVO.
The journal covers a broad spectrum of work, including but not limited to:
Applications of stem cell technology for regenerative medicine,
Development of new animal models of human diseases,
Tissue bioengineering,
Chemical engineering to improve virus-based gene delivery,
Nanotechnology for drug delivery,
Design and synthesis of artificial extracellular matrices,
Development of a true microsurgical operating environment,
Refining data analysis algorithms to improve in vivo imaging technology,
Results of Phase 1 clinical trials,
Reverse translational ("bedside to bench") research.
TVST seeks manuscripts from scientists and clinicians with diverse backgrounds ranging from basic chemistry to ophthalmic surgery that will advance or change the way we understand and/or treat vision-threatening diseases. TVST encourages the use of color, multimedia, hyperlinks, program code and other digital enhancements.
