Advancements in the application of adaptive optics-based retinal imaging technology / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

Adaptive optics(AO)is a technique used to optimize the functionality of optical systems through the reduction of wavefront distortion and optical aberrations. AO-based retinal imaging reduces the occurrence of optical aberrations in the refractive system, consequently improving the resolution and overall quality of retinal imaging. As a result, AO-based retinal imaging has potential wide-ranging application in ophthalmology. A combination of AO, fundus camera, scanning laser ophthalmoscope, optical coherence tomography technique and optical coherence tomography angiography, can be applied to observe the distribution, morphology and function of retinal cone cells in the healthy retinal, and to comprehend the shape and perfusion of retinal vessels in the fine vascular layer. With this technique, it can also possible to perform qualitative and quantitative analysis of the number and shape of cells in the ocular fundus, the cribriform plate, and the microscopic structures of the retinal microvascular system and nerve tissue. It can be expected as a novel tool for the early diagnosis, follow-up of therapy effects, and identification of progression of ophthalmic diseases such as diabetic retinopathy, age-related macular degeneration, glaucoma and hereditary retinal diseases.
