Executive Summary

Diabetic retinopathy (DR) is a leading cause of blindness among adults, but early detection and timely treatment can prevent up to 90% of vision loss cases. Recognizing the critical need for accessible and efficient screening, we partnered with a regional healthcare provider serving a large diabetic population.

About the Client

The client is a regional healthcare provider dedicated to offering comprehensive care to a large and growing diabetic population. With a focus on community health, the organization operates multiple facilities, including clinics in rural and underserved areas, where access to specialized care is often limited.

As diabetes prevalence surged, the healthcare provider faced mounting challenges in managing diabetic retinopathy screenings due to resource constraints, a shortage of specialists, and operational inefficiencies. Committed to improving patient outcomes, the client sought an innovative AI-driven solution to enhance early detection, streamline screening processes, and expand accessibility to critical diagnostic services, especially for at-risk populations in remote regions.

Problem Statement

The healthcare provider faced several challenges in managing diabetic retinopathy screening:

Growing Patient Load

  • With the increasing prevalence of diabetes, the provider struggled to screen all at-risk patients effectively, leading to delays in detection and treatment.

Specialist Shortages

  • Limited availability of ophthalmologists, especially in rural and underserved areas, resulted in many patients not receiving timely screenings.

High Operational Costs

  • Manual screening processes required significant time and resources, limiting scalability.

The healthcare provider needed a solution to improve diagnostic accuracy, enhance efficiency, and make DR screening more accessible, particularly in resource-limited settings.

Solution Overview

We developed an AI-driven diabetic retinopathy screening solution leveraging deep learning for retinal image analysis. The system automates the detection of DR, assigns severity scores, and integrates seamlessly into the provider’s existing workflows, ensuring ease of use and immediate impact.

Key Components

#1 Data Preprocessing

  • Databricks: Cleaned, standardized, and augmented retinal image datasets.
  • OpenCV: Enhanced image quality by adjusting brightness, contrast, and reducing noise.

#2 AI Model

  • EfficientNet CNN: Fine-tuned for diabetic retinopathy detection using publicly available datasets like EyePACS.
  • TensorFlow/Keras: Model development, training, and augmentation.

#3 Deployment

  • Hosted on Azure AI for real-time analysis with low latency.

#4 Severity Scoring and Alerts

  • Assigned severity levels (mild, moderate, severe) to each case and flagged critical cases for immediate review.

#5 Reporting and Monitoring

  • Developed a clinician-friendly dashboard using Power BI for monitoring AI predictions and screening outcomes.

Tech Stack & Tools

Databricks

  • Data cleaning, preprocessing, and augmentation workflows.
