Research progress on wide-field multimodal image of peripheral retinal degeneration

Abstract

Peripheral retinal degeneration is a typical lesion in ophthalmic clinical practice. Each type of degeneration affects distinct retinal layers and may lead to sight-threatening complications. Due to its specific location, where current ophthalmic imaging technologies have difficulties observing, the pathogenesis remains unclear despite previous works. This review outlines the characteristics of peripheral retinal degeneration by different wide-field imaging technologies, including ultra-wide field fundus imaging, wide field spectral domain optical coherence tomography, optical coherence tomography angiography and fundus fluorescein angiography, as well as new perspectives on their pathogenesis or pathological characteristics so as to provide new ideas for clinical diagnosis and management. Due to the small size of sample and the lack of prospective and long-term observation of multimodal imaging, it is still impossible to comprehensively evaluate the progression and risk of different types of degeneration. Therefore, it is expected that wide-field multimodal imaging technology will be more widely applied to study the mechanism of peripheral retinal degeneration and guide the clinical practice options.
