PURPOSE To elucidate the relation between optical coherence tomography (OCT) scans and retinal histology in normal and retinal degeneration (rd) chickens. METHODS Retinas from adult normal and rd chickens were examined in vivo with OCT at 850 nm and compared quantitatively with stained cryosections of unfixed retinas from the same locations. RESULTS The(More)
Low coherence laser Doppler interferometry (LDI) allows high precision measurements of the axial length of the eye and of the thickness of the individual layers of the ocular fundus. Here, we used LDI to monitor diurnal changes in these dimensions in eyes of newly hatched chicks and one-year-old chickens with normal or altered visual input. In chicks and(More)
Choroidal thickness and axial eye length in the chick undergo day/night fluctuations that can also be modulated by visual experience. In the present study, we tested the effect of parasympathetic and sympathetic denervations on both day/night and image dependent changes in ocular dimensions. We also correlated such changes with fluctuations in intraocular(More)
In this paper, we present an "Asymmetric Passive Optical Network for xDSL and FTTH Access" (PANDA) architecture that is suitable for providing end-users with broadband connections in a cost-effective and non-disruptive fashion. We first describe the need for expanding the current ADSL access to VDSL (and ultimately FTTH), as well as the network upgrades(More)
