Adaptive optics for retinal imaging

Definition

Adaptive optics for retinal imaging is a technology that uses real-time adjustments to correct optical aberrations in order to obtain high-resolution images of the retina. This technique enhances the quality of retinal images by compensating for distortions caused by imperfections in the eye's optical system, allowing for better visualization of cellular structures and diseases.
