Predicting progression to proliferative diabetic retinopathy using automated versus manual quantification of retinal haemorrhages
Revolutionizing Diabetic Retinopathy Progression Prediction with AI-Driven Retinal Analysis
This study demonstrates a significant leap in ophthalmic diagnostics, comparing automated deep-learning algorithms with traditional manual grading for predicting proliferative diabetic retinopathy (PDR). By leveraging ultra-widefield imaging, our AI models provide an efficient and objective approach, correlating highly with manual methods while identifying critical risk factors for disease progression.

Study Design and Automated Analysis Process
This study retrospectively analyzed 63 eyes with non-proliferative diabetic retinopathy (NPDR) from patients in India, focusing on those with UWF pseudocolor imaging at baseline and 1-year follow-up. Eyes with dense cataracts, other media opacities, high myopia, or other ocular diagnoses were excluded to maintain data quality and focus. Manual segmentation of retinal hemorrhages was performed by two experienced graders using custom GRADOR software, with a 20% subset regraded for reproducibility. Automated detection and quantification were performed using EyeRead UWF software (Eyenuk), computing total hemorrhage frequency, area, and average distance from the optic nerve center for both ETDRS 7 standard fields and peripheral extended fields.
Key Findings and Predictive Power
Out of 63 NPDR eyes, 29 (46%) progressed to PDR within one year. Automated measurements of total hemorrhage frequency, area, and distance from the optic nerve were significantly lower than manual grading (p < 0.001) but showed strong correlations (r = 0.5-0.96). Crucially, the distance of hemorrhages from the optic nerve was identified as a significant risk factor for progression to PDR by both manual (OR 0.66, p = 0.04) and automated (OR 0.64, p = 0.045) approaches. This highlights the predictive utility of automated analysis despite quantitative differences from manual methods.
Implications for Enterprise AI Integration
The study concludes that automated detection of retinal hemorrhages can serve as a surrogate for manual grading in predicting PDR progression, offering a more efficient and objective tool for DR management. While automated detection may yield lower lesion counts due to precision differences in border identification, its ability to predict progression remains strong. The importance of peripheral hemorrhages and their distance from the ONH as a robust predictor underscores the value of UWF imaging and comprehensive AI analysis in advanced DR staging. Future research will explore other DR features and diverse cohorts.
