Intra-operative ocular parameter sensing

Abstract

A patient is monitored during a medical procedure, such as spinal surgery, to identify a condition indicative of the possible onset of blindness or damage to the patient's eye or eyes. 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.
