Conventional diagnostic methods like fluorescein angiography (FA) are invasive and lack depth-resolved structural information, limiting their effectiveness.

Ultra-widefield optical coherence tomography angiography (UWF-OCTA) offers a non-invasive alternative with enhanced imaging capabilities for peripheral retinal evaluation.

UWF-OCTA effectively identifies key retinal microvascular lesions, including neovascularization, non-perfusion areas, and microaneurysms, with high sensitivity and specificity.

Despite its advantages, UWF-OCTA has limitations such as segmentation errors and a smaller field of view compared to conventional angiography.
