Illustration of the OCT ophthalmoscopes for retinal, choroidal and hyaloid imaging. (a) For retinal and choroidal imaging, the ocular lens delivers a collimated beam to the eye, making a focal spot that covers both retinal and choroidal layers. The image on the right is a representative OCT B-scan visualizing the retinal and choroidal layers. (b) The ocular lens is translated further away from the focusing lens to deliver a converging beam and makes a focus in the middle of vitreous space. The image on the right is a representative OCT B-scan visualizing the hyaloid vessels in the vitreous space as well as the posterior surface of the lens, retinal and choroidal layers. Scale bars: 200 μm.
