While MRD is simply allowing a measurement of how wide the lid is open and performing readily repeat- able diagnostics, Dr. Sheppard said that this type of heads-up display is "absolutely" worthwhile for a vari- ety of future surgical management informational applications when tasked to augment the surgeon's mastery of the operating environ- ment. These displays might include helpful digital overlays pertaining to vitrectomy and cataract surgery, for example. "If you want to watch the IOP, suction, vacuum or irrigation pa- rameters, [that will likely be possi- ble with Google Glass in the near future]," he said. Medical recording may also be a strong feature of Google Glass. In June 2015, Ehsan Rahimy, MD, retina service, Wills Eye Hospital, Thomas Jefferson University, Phila- delphia, reported in JAMA Ophthal- mology an experience with recording scleral buckling surgery with the device. "Google Glass recorded each of the following steps of the scleral buckling procedure: conjunctival peritomy, rectus muscle isolation, administration of the sub-Tenon bock, external localization of retinal breaks and treatment with cryother- apy, passage of scleral buckle and suture placement, external drainage of subretinal fluid, anterior chamber paracentesis with intravitreal gas tamponade injection, and closure of the conjunctiva followed by subcon- junctival corticosteroid and antibi- otic injection," Dr. Rahimy reported in the study. "The still images and video clips seemed detailed enough for viewers who were not present during the surgery to recognize the salient steps of the procedure. Similarly, the simultaneous audio recording obtained with the video sounded clear to those who listened (retina fellows, attending surgeons, and ophthalmology residents)." A conventional microscope- based recording of such surgery is difficult to obtain "because the surgical maneuvers are performed off the central axis." "Google Glass, with its point-of- view style of recording, has the po- tential to make a novel contribution to the field of medical education," Dr. Rahimy said.
