Abstract
An epiretinal membrane (ERM) visualization system includes an OCT system operable to generate an OCT image of a region of a patient's eye, the region of the patient's eye including an ERM. The ERM visualization system further includes an image processing unit operable to process the OCT image to identify the ERM by differentiating the ERM from other structures within the region of the patient's eye and generate an ERM map depicting one or more characteristics (including at least a location of a portion of the ERM within the region of the patient's eye) of the identified ERM. The ERM visualization system further includes a display operable to display the ERM map.

An epiretinal membrane visualization system, comprising:
- an OCT system operable to generate an OCT image of a region of a patient's eye, the region of the patient's eye including an epiretinal membrane (ERM);
- an image processing unit operable to:
- process the OCT image to identify the ERM by differentiating the ERM from other structures within the region of the patient's eye;
- and
- generate an ERM map depicting one or more characteristics of the identified ERM, the one or more characteristics including at least a location of a portion of the ERM within the region of the patient's eye;
- an imaging unit operable to generate a live video image of the region of the patient's eye during a surgical procedure;
- and
- a display operable to display the ERM map as an overlay on the image generated by the imaging unit, wherein the ERM map comprises a static ERM map registered and overlaid on the live video image.
A method, comprising:
- generating an OCT image of a region of a patient's eye, the region of the patient's eye including an epiretinal membrane (ERM);
- processing the OCT image to identify the ERM by differentiating the ERM from other structures within the region of the patient's eye;
- generating an ERM map depicting one or more characteristics of the identified ERM, the one or more characteristics including at least a location of a portion of the ERM within the region of the patient's eye;
- and
- generating a live video image of the region of the patient's eye during a surgical procedure;
- and
- displaying the ERM map as an overlay on the image generated by the imaging unit, wherein the ERM map comprises a static ERM map registered and overlaid on the live video image.
