“…Sato [12] also using TD-OCT to evaluate MH closure, reported a decrease in the subretinal fluid and foveal cysts on POD 1 in one eye with SF6 gas tamponade, but MH closure was not complete until POD 2. Kasuga et al [7] acquired good TD-OCT images through the gas in 4 of 7 eyes (57.1%) with MH using SF6 gas tamponade on POD 1, and the MH in all four eyes was closed. Because the TD-OCT images of these eyes revealed no changes in the anatomic configuration of the macula over the following 3 months, the authors concluded that they were able to confirm the success of the MH surgery within 24 hours after surgery.…”

AIM:To evaluate whether spectral-domain optical coherence tomography (SD-OCT) can be used to determine if macular hole (MH) closure occurred in gas-filled eyes without postoperative face-down positioning. METHODS: This retrospective, consecutive, observational case series included 19 eyes of 19 MH patients who underwent vitrectomy with SF6 gas tamponade without postoperative face-down positioning. The MHs of all patients were evaluated using SD-OCT before and at 3 hours after surgery; daily until confirming the MH status; and at 1 and 3 months postoperatively. RESULTS: Three hours after surgery, no interpretable images were obtained for any of the 19 eyes. On postoperative day 1, sufficiently clear images were obtained by SD-OCT to determine MH closure in 10 eyes (52.6%), 16 eyes (84.2%) on postoperative day 2, and 18 eyes (94.7%) on postoperative day 3. Clear images of the remaining eye were not obtained until postoperative day 5, likely due to pupillary capture of the intraocular lens. All MHs closed after the first surgery. CONCLUSIONS: Hole closure can be precisely determined by postoperative day 5 using SD-OCT. If SD-OCT images through gas reveal that the hole is still open, then face-down positioning should be used so that residual gas in the vitreous cavity can close the hole, or a second vitrectomy should be planned.

“…In 2000, Kasuga et al [7] reported MH closure in 4 of 7 (58%) gasfilled eyes based on time-domain optical coherence tomography (TD-OCT) on postoperative day (POD) 1. Eckardt et al [8] and Masuyama et al [9] used spectral-domain OCT (SD-OCT) to determine MH closure in gas-filled eyes.…”

“…Perioperative OCT has since facilitated the identification of pathologic structures and surgically-induced alterations that are difficult to detect with alternative ophthalmic clinical instruments [53][54][55][56][57][58][59][60][61][62][63][64]. Initial investigations into OCT's potential for surgical diagnostics in other microsurgeries were also conducted for the first time in the late 1990's [65].…”

During microsurgery, en face imaging of the surgical field through the operating microscope limits the surgeon's depth perception and visualization of instruments and subsurface anatomy. Surgical procedures outside microsurgery, such as breast tumor resections, may also benefit from visualization of the sub-surface tissue structures. The widespread clinical adoption of optical coherence tomography (OCT) in ophthalmology and its growing prominence in other fields, such as cancer imaging, has motivated the development of intraoperative OCT for real-time tomographic visualization of surgical interventions. This article reviews key technological developments in intraoperative OCT and their applications in human surgery. We focus on handheld OCT probes, microscope-integrated OCT systems, and OCT-guided laser treatment platforms designed for intraoperative use. Moreover, we discuss intraoperative OCT adjuncts and processing techniques currently under development to optimize the surgical feedback derivable from OCT data. Lastly, we survey salient clinical studies of intraoperative OCT for human surgery.

“…At this time, there is insufficient evidence to allow firm conclusions as to whether prone positioning after macular hole surgery influences closure rates. More recently, the early postoperative state of macular hole can be investigated because imaging of the macular region through gas bubble may now be obtained by advances in optical coherence tomography technology (Eckardt et al, 2008;Kasuga et al, 2000;Masuyama et al, 2009). …”
