Paper Abstract

In-vivo dynamic light scattering measurements in the vitreous of the human eye are presented. The set-up employs single-mode optical fibers for the delivery of the excitation beam and for the collection of the scattered light. High sensitivity and good spatial resolution are achieved using a novel scattering geometry: the excitation beam is shaped into a hollow cone and the scattered light collected through its central part. The apparatus exhibits excellent safety characteristics: the optical power entering the patient's eye is 36 times less than the maximum laser power at the cornea recommended for intrapupil exposure by the ANSI standard. Following a description of the instrument, examples of in-vivo measurements in the vitreous are discussed in order to demonstrate the possible clinical use of this technique.
