dc.description.abstract Purpose. To investigate the in vivo incision architecture using spectral domain optical coherence tomography (SD-OCT) in 23-gauge and 25-gauge transconjunctival sutureless pars plana vitrectomy (TSPPV). Methods. A prospective observational study of 22 eyes of 22 patients that underwent three-port 25-gauge (10 eyes) or 23-gauge (12 eyes) TSPPV was performed. the three sclerotomies sites in each eye were analyzed by Corneal Adapter Model (CAM) RTVue SD-OCT (Optovue Inc., Fremont, CA, USA) with wound cross-section images (longitudinal and transversal) on days 1, 7, and 30 postoperatively. Transversal and longitudinal length, location, angle between the conjunctival surface tangent and the incision plane, and architecture deformations were evaluated. Results. All patients (22 eyes) completed the study and surgeries lasted less than 60 minutes. All wounds were obliquely performed, 23-gauge mean angle was 23 +/- 5 degrees, and 25-gauge angule was 21 +/- 4 degrees. Twenty-three-gauge sclerotomy transversal mean length was 1122 +/- 242 mu m and 25-gauge transversal sclerotomy mean length was 977 +/- 174 mu m; 23-gauge longitudinal mean length was 363 +/- 42 mu m and 25-gauge longitudinal sclerotomy mean length was 234 +/- 19 mu m; 23-gauge open wound thickness mean was 61 +/- 28 mu m and 25-gauge open wound thickness mean was 22 +/- 6 mu m. All results were statistically significant (P < 0.05). No vitreous incarceration or silicone oil residue was observed in incision sites with both gauges. Conclusions. the 23-gauge and 25-gauge architectural wound constructions were well visualized using CAM SD-OCT. Statistical differences between the two gauges were observed throughout the study period. en
