Abstract

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

Description

Technical field [0001] The present disclosure relates generally to improved visualization of ophthalmic surgery, and more specifically to optical coherence tomography guided epiretinal detachment. Background technique [0002] The epiretinal membrane (ERM) is a piece of fibrous tissue that can form on the macula and may act as a film, making it more difficult to see through the film. The film can also shrink like scar tissue, which can pull on the retina. ERM may cause various retinopathy, including retinal wrinkles, retinal distortion, cystoid, macular edema, and small hemorrhages. [0003] Currently, the only way to treat ERM is surgical removal through vitrectomy. In such a procedure, the vitreoretinal surgeon uses very fine forceps to grasp the membrane at high magnification and gently peel it off the retina (commonly referred to as "ERM dissection"). However, due to its thin and translucent nature, visualization of ERM can be difficult, making ERM dissection a challenging p...
