    High-resolution imaging of photoreceptors in healthy human eyes using an adaptive optics retinal camera

    Purpose To determine the effects of age on perifoveal cone density in healthy subjects using adaptive optics. Methods Healthy subjects of various ages were imaged using an adaptive optics retinal camera (RTX-1 ® Imagine Eyes, Orsay, France). All patients underwent a comprehensive ophthalmologic examination and retinal imaging using spectral-domain optical coherence tomography (Spectralis ® , Heidelberg Engineering, Heidelberg, Germany). Cone density together with cone spacing and cone mosaic packing were measured in the nasal and temporal area 450 µm from the fovea. A multivariate analysis was performed to determine which of the following parameters were related to a decrease in cone density: age ...
