Measuring Dynamics of Scattering Centers in the Ocular Fundus

چکیده
The study is focused on the analysis of the diffusing-wave-spectroscopy signal recorded invivo on the ocular fundus of a rabbit eye. The motion of the scattered sites was measured as a function of the pressure exerted by a Goldmann contact lens and during the moderate temperature increase induced by a therapeutic laser diode. Temporal fluctuations of the signal revel motion of molecules and thus changes in tissues temperature and chorioretinal blood velocity. Experimental results show the ability of the system to detect motion of the scattering sites in the ocular fundus layers during variations of the ocular pressure and laser heating.

Binocular open-view system to perform estimations of aberrations and scattering in the human eye.
We present a system that integrates a double-pass (DP) instrument and a Hartmann-Shack (HS) wavefront sensor to provide information not only on aberrations, but also on the scattering that occurs in the human eye. A binocular open-view design permits evaluations to be made under normal viewing conditions. Furthermore, the system is able to compensate for both the spherical and astigmatic refrac...
متن کاملScattering contribution to the double-pass PSF using Monte Carlo simulations.
PURPOSE Scattering in the eye occurs mainly at two sites: the eye's optical media and the deeper retinal layers. Although the two phenomena are often treated collectively, their spatial domain of contribution to the double-pass Point Spread Function (PSF) is different: the fundus effect is limited to the narrow and middle part of the PSF whereas scattering in the eye's optics extends also to wi...
متن کاملResponse for light scattered in the ocular fundus from double-pass and Hartmann-Shack estimations.
Double-pass (DP) and Hartmann-Shack (HS) are complementary techniques based on reflections of light in the ocular fundus that may be used to estimate the optical properties of the human eye. Under conventional data processing, both of these assessment modes provide information on aberrations. In addition, DP data contain the effects of scattering. In the ocular fundus, this phenomenon may arise...

متن کاملInterference fringe scale for absolute ocular fundus measurement.
Measurements of the human ocular fundus in the three spatial dimensions have not been absolute because measuring techniques have used the optical system of the eye as part of the total ophthalmoscopic system. The ophthalmoscopic magnification due to the total dioptric power of an individual eye can vary substantially from that of the average eye. A new method has been developed to form interfer...
