Abstract
A system and associated methodology allow for monitoring ocular parameters of a patient. Parameters that may be monitored in this regard include ocular perfusion, retinal oxygen saturation and ocular pressure. In one implementation, a device for monitoring the desired parameters includes a contact lens with fiber optic pathways mounted thereon. Light of multiple wavelengths can be transmitted into the patient'"'"'s eyes via input optical pathways. Output optical pathways are associated with a camera for obtaining images of an area of interest within the patient'"'"'s eyes. The images can be processed to obtain information regarding ocular perfusion and/or oxygen saturation. Changes in this regard can be used to identify a condition of interest.

12. A method for use in monitoring a patient, comprising the steps of:
-
identifying a physiological parameter potentially related to patient eye damage;
monitoring said identified physiological parameter during a medical procedure at a patient site separate from eyes of said patient; and
based on said monitoring, taking potentially corrective action in the event of an indication related to said onset of patient eye damage. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
