“…To date, several studies have tested the utility of iOCT under a variety of circumstances, in addition, timely reviews and expert opinions have also enriched our knowledge on iOCT. [2][3][4][5][6][7][8][9][10][11][12] However, a comprehensive review to summarize the pan ophthalmic utility from a clinicians perspective is still lacking, therefore, this comprehensive review was undertaken to analyze the utility of iOCT. Here, we discuss the anterior segment, posterior segment as well as other utilities in a systematic manner.…”

Intraoperative imaging of ocular tissues for diagnostic and therapeutic applications has gained immense admiration in recent years. The real time cross-sectional imaging, as well as three and four dimensional reconstruction abilities of intraoperative optical coherence tomography (iOCT), has enhanced our knowledge on many fronts in surgical maneuvers. In this review, we discuss the iOCT discovered constructive knowledge in the cornea, cataract, refractive, glaucoma, pediatric ocular, and various retinal conditions. The practical utility with decision modifying aspects along the specified ocular tissues and with respect to specific ocular entities have been narrated. Moreover, limitations and future directions have also been emphasized to make ophthalmic care more comprehensive in the future.

“…However, a valid definition of prognostic factors which individually provides a clear and reliable answer to the question of definitive surgical outcome has not been found yet. Therefore, it seems obvious that most likely not only preoperative, but also intraoperative influences like macular stretching act on the retina and thus impact visual function [11,14] . Aim of this study was to investigate whether stronger dilation of the retina during membrane peeling could be associated with a poorer visual outcome and reduced recovery of the macular morphology, based on the hypothesis that retinal overstretching causes damage to Müller glia cells [15] .…”

AIM: To measure the difference of intraoperative central macular thickness (CMT) before, during, and after membrane peeling and investigate the influence of intraoperative macular stretching on postoperative best corrected visual acuity (BCVA) outcome and postoperative CMT development. METHODS: A total of 59 eyes of 59 patients who underwent vitreoretinal surgery for epiretinal membrane was analyzed. Videos with intraoperative optical coherence tomography (OCT) were recorded. Difference of intraoperative CMT before, during, and after peeling was measured. Pre- and postoperatively obtained BCVA and spectral-domain OCT images were analyzed. RESULTS: Mean age of the patients was 70±8.13y (range 46-86y). Mean baseline BCVA was 0.49±0.27 logMAR (range 0.1-1.3). Three and six months postoperatively the mean BCVA was 0.36±0.25 (P=0.01 vs baseline) and 0.38±0.35 (P=0.08 vs baseline) logMAR respectively. Mean stretch of the macula during surgery was 29% from baseline (range 2%-159%). Intraoperative findings of macular stretching did not correlate with visual acuity outcome within 6mo after surgery (r=-0.06, P=0.72). However, extent of macular stretching during surgery significantly correlated with less reduction of CMT at the fovea centralis (r=-0.43, P<0.01) and 1 mm nasal and temporal from the fovea (r=-0.37, P=0.02 and r=-0.50, P<0.01 respectively) 3mo postoperatively. CONCLUSION: The extent of retinal stretching during membrane peeling may predict the development of postoperative central retinal thickness, though there is no correlation with visual acuity development within the first 6mo postoperatively.

“…Binder et al first used a microscope-mounted unit following surgical manipulations [ 28 ]. The Duke [ 29 – 38 ], Cleveland Clinic/Case Western Reserve [ 36 , 39 – 47 ], Vanderbilt [ 48 ], and international groups [ 28 , 49 – 52 ] developed improvements for the microscope-mounted intraoperative OCT systems with commercial US Food and Drug Administration (FDA)-approved systems available for the operating room [ 53 ].…”

A Review of Robotic and OCT-Aided Systems for Vitreoretinal Surgery

The introduction of the intraocular vitrectomy instrument by Machemer et al. has led to remarkable advancements in vitreoretinal surgery enabling the limitations of human physiologic capabilities to be reached. To overcome the barriers of perception, tremor, and dexterity, robotic technologies have been investigated with current advancements nearing the feasibility for clinical use. There are four categories of robotic systems that have emerged through the research: (1) handheld instruments with intrinsic robotic assistance, (2) hand-on-hand robotic systems, (3) teleoperated robotic systems, and (4) magnetic guidance robots. This review covers the improvements and the remaining needs for safe, cost-effective clinical deployment of robotic systems in vitreoretinal surgery.
