| Abstract: | The transparency of most retinal cell classes typically precludes imaging them in the living eye; unless invasive methods are used that deploy extrinsic contrast agents. Using an adaptive optics scanning light ophthalmoscope (AOSLO) and capitalizing on the large numerical aperture of the mouse eye, we enhanced the contrast from otherwise transparent cells by subtracting the left from the right half of the light distribution in the detector plane. With this approach, it is possible to image the distal processes of photoreceptors, their more proximal cell bodies and the mosaic of horizontal cells in the living mouse retina.OCIS codes: (170.4460) Ophthalmic optics and devices, (330.4300) Vision system - noninvasive assessment, (110.1080) Active or adaptive optics, (330.7324) Visual optics, comparative animal models |
