    This study introduces the feature interaction Transformer network (FIT-Net) for accurate classification of pathological myopia (PM) using retinal optical coherence tomography (OCT) images. FIT-Net effectively integrates multi-scale features from horizontal and vertical scans, improving diagnostic performance.

    Area of Science:

    • Ophthalmology
    • Medical Imaging
    • Artificial Intelligence

    Background:

    • Accurate classification of pathological myopia (PM) from retinal optical coherence tomography (OCT) images is crucial for clinical diagnosis.
    • Challenges in PM diagnosis include variations in lesion appearance across different OCT scanning directions (horizontal and vertical).

    Purpose of the Study:

    • To develop a novel deep learning model, the feature interaction Transformer network (FIT-Net), for improved automated diagnosis of PM using OCT images.
    • To enhance feature representation by integrating multi-scale image information and cross-directional features.

    Main Methods:

    • Proposed FIT-Net architecture incorporating dual-scale Transformer (DST) blocks and an interactive attention (IA) unit.
    • Developed six dual-view feature fusion methods to combine horizontal and vertical OCT scan data.
