Area of Science:

Ophthalmology
Medical Imaging
Artificial Intelligence

Background:

Macular pathologies lead to substantial vision loss.
Optical coherence tomography (OCT) is crucial for diagnosing retinal diseases.
Existing deep learning models struggle with noise in OCT images, hindering accurate classification.

Purpose of the Study:

To develop a robust deep learning model for classifying retinal diseases from OCT images.
To overcome limitations of traditional networks in handling noise.
To improve diagnostic accuracy for macular pathologies.

Main Methods:

Proposed a multi-scale-denoising residual convolutional network (MS-DRCN).
Incorporated a soft-denoising block (SDB) for automatic noise thresholding.
Utilized a multi-scale context block (MCB) and feature fusion block (FFB) for enhanced feature extraction and integration.

Main Results:

Achieved 96.4% and 96.5% accuracy on OCT2017 and OCT-C4 datasets, respectively.
Demonstrated superior robustness against Gaussian and speckle noise compared to other methods.
Showcased accuracy improvements of 0.6% to 2.9% over ResNet under varying noise conditions.

Conclusions:

The MS-DRCN effectively classifies retinal diseases from noisy OCT images.
The proposed network architecture enhances feature extraction and noise reduction capabilities.
This method offers a robust solution for improving OCT-based retinal disease diagnosis.
