“…However, our observations unexpectedly showed no statistically significant difference in vitreous incarceration between the 2 groups postoperatively, which was in agreement with previous studies. 2,21,22 During vitrectomy, the vitreous around the infusion site is most difficult to remove. Sabti proved that vitreous shaving around sclerotomy sites using depressed vitrectomy significantly reduces vitreous incarceration.…”

“…[8][9][10][11][12][13][14][15] In our study, the presence of vitreous incarceration in the inner face of the sclerotomies was related to the absence of conjunctival blebs over the incisions. In addition, the amount (grade) of vitreous entrapment in the sclerotomies was inversely associated with the amount of subconjuntival leakage.…”

“…Previously, studies that analyzed TSV sclerotomies by ultrasound biomicroscopy (UBM) 14,15 did not find significant association between the presence of a conjunctival bleb and vitreous incarceration. However, they evaluated the sclerotomies one day after the surgery, so factors involved in subconjunctival bleb resolution, such as postoperative pressure patching and subconjunctival fluid expression by blinking were not avoided.…”

“…Recently, some authors have studied sclerotomy occlusion incompetency after vitrectomy. [8][9][10][11][12][13][14][15] These studies have identified the gauge of the cannulas, 11 the angle of the incisions, 14 the preoperative diagnosis, 9 the surgical duration, 9 and the age of the patient 9 as factors involved in the postoperative sclerotomy leakage. However, the influence that the presence of incisional vitreous incarceration may exert on sclerotomy closure competency was not considered previously.…”

Invest Ophthalmol Vis Sci. 2013;54:4366-4371. DOI:10.1167/iovs.13-12008 PURPOSE. To evaluate the influence that vitreous incarceration may exert on the presence of postoperative conjunctival blebs over sclerotomies after transconjunctival sutureless vitrectomy (TSV). Blebs are formed by incisional leakage due to incompetent closure. METHODS.Experimental study in which 23-gauge TSV was performed in 146 cadaveric pig eyes. Once the vitrectomy was finished, triamcinolone was injected inside the vitreous cavity for staining residual vitreous, one of the superior cannulas was extracted over the light probe, and the other cannula was removed with the plug inserted. Postoperative conjunctival blebs in superior sclerotomies were assessed by anterior-segment optical coherence tomography (AS-OCT) in a masked fashion; nondetectable blebs were classified as grade 0 (B0), thin bleb (half scleral thickness) as grade 1 (B1), and thick bleb (>half scleral thickness) as grade 2 (B2). Postoperative incisional vitreous entrapment was evaluated by slit-lamp photographs in a masked way; no incarceration was classified as grade 0 (V0), thin incarceration as grade 1 (V1), and thick incarceration as grade 2 (V2).RESULTS. Conjunctival blebs were found in 13.7% of the sclerotomies (11.3% bleb-B1, 2.4% bleb-B2). Vitreous incarceration was found in 96.5% of the sclerotomies without bleb (B0), 81.8% of the incisions with bleb-B1, and 14.3% of the wounds with bleb-B2. Vitreous incarceration was significantly associated with the absence of conjunctival bleb (P < 0.001).CONCLUSIONS. Vitreous incarceration in sclerotomies is related to less incisional leakage in our experimental model. Maneuvers that reduce vitreous entrapment, such as the interposition of a nonhollow probe during the cannula extraction, could decrease the sclerotomy closure competency.Keywords: vitrectomy, vitreous incarceration, conjunctival bleb, sclerotomy closure, experimental model D uring the last decade, 23-and 25-gauge transconjunctival sutureless vitrectomies (TSV) have gained popularity and acceptance.1,2 In contrast to conventional 20-gauge sclerotomies, 23-and 25-gauge incisions allow minimally invasive vitreoretinal surgery using smaller sutureless incisions, as compared with conventional pars plana vitrectomy 3,4 ; however, they have been related to higher rates of endophthalmitis and hypotony, due to the occasional lack of incisional closure. 5-7Recently, some authors have studied the conjunctival bleb formation over sutureless sclerotomies after vitrectomy, resulting from sclerotomy occlusion incompetency. [8][9][10][11][12][13][14][15] These studies have identified parameters related to the sclerotomy architecture 11,14 and the surgery 9 as factors involved in the postoperative sclerotomy leakage.
