Area of Science:

  • Ophthalmology and Medical Imaging
  • Artificial Intelligence in Healthcare
  • Biomedical Signal Processing

Background:

  • Retinal lesions cause irreversible visual impairment, necessitating early diagnosis and precise identification.
  • Optical coherence tomography (OCT) is crucial for ophthalmology but faces challenges in interpreting complex structures and noise.
  • Accurate AI-assisted diagnosis of retinal conditions is vital for effective disease management.

Purpose of the Study:

  • To develop a novel AI framework, MSLI-Net, for improved analysis of retinal images.
  • To enhance the accuracy and efficiency of diagnosing retinal diseases using OCT.
  • To address challenges of structural complexity and noise in OCT imaging for AI applications.

Main Methods:

  • Proposed MSLI-Net framework utilizes a ResNet50 backbone with a multi-scale dilation fusion (MDF) module for global receptive field enhancement.
  • Integrated multi-segmented lesion localization (LLM) within a modified feature pyramid network (FPN) for feature extraction and noise suppression.
  • Employed a wavelet subband spatial attention (WSSA) module for noise reduction by processing low- and high-frequency wavelet subbands.

Main Results:

  • MSLI-Net achieved 96.72% accuracy in retinopathy classification on the OCT-C8 dataset.
  • Demonstrated strong discriminative performance, highlighting the model's potential for clinical use.
  • The framework effectively handled complex retinal structures and noise interference.

Conclusions:

  • MSLI-Net offers novel research directions for early retinal disease diagnosis.
  • The model contributes to the advancement of high-precision medical imaging-assisted diagnostic systems.
  • This AI approach shows significant promise for improving patient outcomes in ophthalmology.
