Compact Adaptive Optics Scanning Laser Ophthalmoscope with Phase Plates

Abstract

Adaptive optics has emerged as an empowering technology for retinal imaging with cellular resolution. This technology holds potential for non-invasive detection and diagnoses of the most common eye diseases such as glaucoma, diabetic retinopathy and age-related macular degeneration (AMD). However, the cost and complexity of adaptive optics ophthalmoscopes currently impede its clinical use. A scanning laser ophthalmoscope with phase plate has the potential to establish adaptive optics in a clinical application by simplifying its incorporation in the prevailing systems. Phase plates can correct aberrations down to diffraction limit and can be easily incorporated into ophthalmoscopes to improve the retinal image quality.
