Abstract: A system of visualizing a target site in an eye, using a polarization sensitive optical coherence tomography (PS-OCT) device, includes a controller having at least one processor and at least one non-transitory, tangible memory on which instructions are recorded. The target site is one or more vitreous opacities in the vitreous humor of the eye. The controller is configured to receive PS-OCT data and determine at least one parameter corresponding to birefringence properties of collagen fibrils in the vitreous humor based on the PS-OCT data. The at least one parameter includes respective spacing of the collagen fibrils. The controller is configured to determine a respective location of the one or more vitreous opacities when the at least one parameter is outside a predefined range and generate a control signal adapted for guiding a treatment beam at the respective location of the one or more vitreous opacities.
