Advancing optical coherence tomography angiography to the clinic

Area of Science:

• Ophthalmology
• Medical Imaging
• Biomedical Engineering

Background:

• Optical coherence tomography angiography (OCTA) is an advanced imaging technique.
• OCTA provides high-resolution visualization of vascular anatomy, including capillaries.
• It enables the detection of pathologies like capillary dropout and neovascularization.

Purpose of the Study:

• To review OCTA measurements for diagnosing and monitoring blinding eye diseases.
• To analyze the clinical utility and potential of OCTA in patient management.
• To examine OCTA's role in diabetic retinopathy, age-related macular degeneration, and glaucoma.

Main Methods:

• Review of current literature on OCTA applications in ophthalmology.
• Analysis of OCTA imaging capabilities for vascular visualization and quantification.
• Examination of specific OCTA metrics relevant to prevalent blinding conditions.

Main Results:

• OCTA offers detailed insights into microvascular changes associated with blinding eye diseases.
• Quantification using OCTA supports diagnostics, staging, and treatment response evaluation.
• Specific OCTA measurements show promise for managing diabetic retinopathy, AMD, and glaucoma.

Conclusions:

• OCTA is a valuable tool for visualizing and quantifying retinal vasculature.
• Its application in prevalent blinding diseases offers significant potential for improved patient care.
• Careful interpretation of OCTA measurements is crucial for effective clinical use.
