Differential artery-vein analysis in quantitative retinal imaging: a review

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Quantitative retinal imaging is crucial for diagnosing, staging, and monitoring eye diseases.
• Artery and vein systems in the retina exhibit distinct changes based on disease type and severity.
• Current imaging methods can be enhanced by analyzing these differential vascular changes.

Purpose of the Study:

• To summarize the technical principles behind differential artery-vein (AV) analysis.
• To review the clinical applications of differential AV analysis in various retinal imaging modalities.
• To highlight the benefits of AV analysis for improving quantitative retinal imaging performance.

Main Methods:

• Review of technical rationales for differential AV analysis.
• Summary of clinical applications across fundus photography, OCT, and OCTA.
• Analysis of how differential AV analysis improves imaging interpretation.

Main Results:

• Differential AV analysis offers improved performance in quantitative retinal imaging.
• Specific examples of differential AV analysis in fundus photography, OCT, and OCTA are discussed.
• The method provides a more nuanced understanding of vascular changes in eye diseases.

Conclusions:

• Differential AV analysis is a valuable technique for enhancing quantitative retinal imaging.
• Its application across multiple imaging modalities supports broader clinical utility.
• This approach holds significant potential for advancing eye disease diagnostics and management.
