Tabular comparison between the different imaging modalities.

Modality	When to Use	Cost	Pros.	Cons.
Color Fundus Photographs (CFP)	Screening for retinal abnormalities	Low cost	Detailed images of the back of the eye.	Inconsistent pigmentation, inability to resolve fundus depth.
Optical Coherence Tomography (OCT)	Evaluation of retinal disorders	High cost	High-resolution cross-sectional images of the retina.	Limited by medium opacities, operator skill required.
Optical Coherence Tomography Angiography (OCTA)	Detection of microvascular alterations	Moderate cost	Non-invasive, three-dimensional imaging of blood vessels.	Limited normative data, affected by media opacity.
Fluorescein Angiography (FA)	Identifying and categorizing CNV	Moderate cost	Evaluation of retinal and choroidal circulation pathology.	Invasive, requires dye injection, limited to 2D imaging.
Indocyanine Green Angiography (ICG)	Visualization of choroidal circulation	Moderate cost	Deeper penetration into the retina, clearer images of choroidal veins.	Invasive, limited diffusion, requires skilled interpretation.
