A Comparative Analysis of Use of Google Glass versus. GoPro Intraoperative Video Recording of Scleral Buckle Surgery.

ABSTRACT: Importance The scleral buckle technique is difficult to teach, given a decrease in the frequency of its use and the challenges of its video recording. Background This study compares two different modalities for recording intraoperative videos of scleral buckle surgery. Design Present study is a cross-sectional survey conducted in an academic hospital. Participants A total of 36 medical students, ophthalmologic residents, and vitreoretinal surgery fellows participated in this survey. Methods Five scleral buckle surgeries were filmed simultaneously using Google Glass and GoPro. Single-masked survey of trainees comparing video and audio quality of 38 10-second clips from each device, and listing the steps of scleral buckle surgery. Institutional review board approval and informed consent were obtained. Main Outcome Measures Trainees were asked for grading the video device with respect to audio and video quality as favorable or unfavorable. Results GoPro clips had more favorable ratings of video (73.3%) and audio (75.9%), compared with Google Glass (36.7 and 58.5%, respectively; p < 0.005). A total of 2.8% respondents listed the correct order of surgical steps in pretest, compared with 55.6% in posttest ( p < 0.005). Conclusion and Relevance Wearable recording devices can allow for video recording of scleral buckle surgery which has high utility in teaching trainees. GoPro and Google Glass each have distinct advantages.

Project description:IntroductionScleral buckling (SB) tends to be more challenging and time-consuming for compared to the pars plana vitrectomy for repairing rhegmatogenous retinal detachments (RRDs). This study characterizes a novel and simplified technique for SB.MethodsIn this single-masked randomized interventional study, patients with RRDs who were eligible for SB were randomly assigned to either the standard (S) or modified (M) technique of SB. In the modified approach, neither intraoperative break localization nor cryopexy or subretinal fluid drainage was done. A large tire (276/279) was placed where preoperative retinal breaks had been localized with a 240 encircling band placed for support of the remaining retina. Patients were followed for 12 months and the primary outcomes were differences between the surgical groups in operative time, anatomical success, visual acuity, and complication rate.ResultsThirty-six eyes were included in the study (18 in each arm). There were no differences in baseline patient demographics or characteristics including gender, age, lens and macular status, preoperative vision, and symptom duration. The mean length of surgery was 72.2 ± 13.2 and 56.2 ± 9.5 min in groups S and M, respectively (P = 0.001). Complete retinal reattachment at the end of month 12 after single surgery was 80.6% overall; 77.8% (14/18) in group S and 83.3% (15/18) in group M (P > 0.999). After 12 months, both groups achieved similar final best-corrected visual acuity (BCVA): 0.26 ± 0.23 and 0.23 ± 0.17 logMAR in groups S and M, respectively (P = 0.231). Controlling for preoperative BCVA on ANCOVA testing, there were no significant differences in visual improvement between the two groups [F (1,26) = 0.02, P = 0.966 (95% CI) - 0.128 to 0.123)]. Scleral perforation (2:1), vitreous hemorrhage (3:2), and transient rise of intraocular pressure (3:4) all occurred at a low and similar rate between the two groups (S:M).ConclusionModified SB technique was non-inferior compared to the standard approach for anatomical and visual outcomes. Shortening surgical time while maintaining low complication rates makes this an appropriate approach to SB, especially for vitreoretinal surgery trainees.

Project description:INTRODUCTION:Twin-to-twin transfusion syndrome (TTTS) is a potentially lethal condition that affects pregnancies in which twins share a single placenta. The definitive treatment for TTTS is fetoscopic laser photocoagulation, a procedure in which placental blood vessels are selectively cauterized. Challenges in this procedure include difficulty in quickly identifying placental blood vessels due to the many artifacts in the endoscopic video that the surgeon uses for navigation. We propose using deep-learned segmentations of blood vessels to create masks that can be recombined with the original fetoscopic video frame in such a way that the location of placental blood vessels is discernable at a glance. METHODS:In a process approved by an institutional review board, intraoperative videos were acquired from ten fetoscopic laser photocoagulation surgeries performed at Yale New Haven Hospital. A total of 345 video frames were selected from these videos at regularly spaced time intervals. The video frames were segmented once by an expert human rater (a clinician) and once by a novice, but trained human rater (an undergraduate student). The segmentations were used to train a fully convolutional neural network of 25 layers. RESULTS:The neural network was able to produce segmentations with a high similarity to ground truth segmentations produced by an expert human rater (sensitivity?=?92.15%?±?10.69%) and produced segmentations that were significantly more accurate than those produced by a novice human rater (sensitivity?=?56.87%?±?21.64%; p?<?0.01). CONCLUSION:A convolutional neural network can be trained to segment placental blood vessels with near-human accuracy and can exceed the accuracy of novice human raters. Recombining these segmentations with the original fetoscopic video frames can produced enhanced frames in which blood vessels are easily detectable. This has significant implications for aiding fetoscopic surgeons-especially trainees who are not yet at an expert level.
