Imaging techniques for the detection of choroidal neovascularization

Area of Science:

• Ophthalmology
• Retinal Diseases
• Medical Imaging

Background:

• Choroidal neovascularization (CNV) is linked to chorioretinal disorders, causing vision loss through leakage, bleeding, and scarring.
• Precise CNV detection is vital for effective disease management.
• CNV is classified by anatomical location (Type 1, 2, 3) and exudative features (exudative, non-exudative).

Purpose of the Study:

• To review contemporary and novel imaging modalities for detecting and characterizing choroidal neovascularization.
• To discuss the mechanisms, advantages, disadvantages, and clinical applications of various imaging techniques for CNV.

Main Methods:

• Review of current literature on imaging modalities for CNV detection.
• Focus on established techniques and emerging technologies like photoacoustic microscopy, AI, photothermal OCT, and functional fluorescent angiography.

Main Results:

• Each CNV type presents distinct features across different imaging modalities.
• Contemporary imaging techniques offer varying capabilities in visualizing CNV characteristics.
• Novel techniques show promise for enhanced CNV detection and characterization.

Conclusions:

• A comprehensive understanding of imaging modalities is essential for accurate CNV diagnosis and management.
• Emerging technologies may offer improved precision and insights into CNV pathology.
• Continued research into advanced imaging is critical for advancing patient care in retinal diseases.
