“…In this respect, the characteristics of our populations, valved or nonvalved, at the end of the procedure are very similar, because both valved and nonvalved cannula extraction was performed without pulling the vitreous inside the eye, as the light probe does. 11 Moreover, Benitez-Herreros et al 13 found that the source of the incarcerated vitreous, core or pericannular, was related to different closure competencies at the 23-gauge sclerotomy site in their animal model. This implies that the vitrectomy degree may alter the amount of vitreal incarceration 13 and confirms the previous finding in 20-gauge surgery of Sabti et al, 16 who found that the vitreous shaving of sclerotomy sites with scleral indentation significantly reduced vitreous incarceration.…”

“… 1 – 20 Vitreous incarceration may plug the sclerotomy, impacting wound closure and conjunctival bleb formation, and consequently the risk of postoperative hypotony and endophthalmitis. 6 , 11 , 13 Moreover, postoperative contraction of incarcerated vitreous can lead to postoperative retinal break formation and recurrent vitreous hemorrhage. 11 – 23 Vitreous shaving around the sclerotomy site in humans and the cannula extraction technique and, recently, the vitrectomy degree in different areas of the vitreous cavity in animals have all been found to be related to the amount of vitreous incarceration.…”

Aim: In this study we investigated the changes in anterior segment morphology in pseudophakia patients that underwent ultrasound biomicroscopy (UBM) after pars plana vitrectomy (PPV) operation without use of tamponade. Method: Pseudophakic patients who undergo PPV were enrolled in this prospective study between October 2012 and April 2015. Study included patients in whom intraocular tamponade was not used during PPV operation. UBM measurements were performed both before and 10 days after the operation. Anterior chamber depth (ACD) was measured using axial images of anterior segment. Trabecular meshwork-iris angle (TIA), ciliary body thickness (CBT), sclera thickness (ST), trabecular meshwork-ciliary process distance (T-CPD), iris-ciliary processes distance (I-CPD), and iris thickness (IT) were measured at temporal quadrant based on radial section images of the angle. Values measured before and after the operation were statistically compared with each other. Results: This study included 30 patients (18 females, 12 males) that underwent an operation ultrasound biomicroscopy (UBM) after pars plana vitrectomy (PPV) operation without use of tamponade. Mean age was 69.6 ± 9.1 (55 -85) years. Eighteen operations occurred on the left eye whereas twelve operations occurred on the right eye. CBT1, CBT2, CBT Max, T-CPD, and I-CPD were significantly decreased after operation when compared with the values of baseline (before) (p = 0.018, p = 0.012, p = 0.001, p = 0.033, p = 0.015, respectively). Other evaluated parameters did not show statistically significant changes after the operation (p > 0.05). Discussion: PPV results in significant changes in ciliary body morphology together with changes in anterior segment parameters in pseudophakic cases.

Objectives To study the patterns of vitreous incarceration in sutured vs non-sutured sclerotomies in patients subjected to 25gauge macular surgery. Methods A prospective study of 135 eyes affected by epiretinal membrane or macular hole. Vitreal disposition was evaluated via ultrasound biomicroscopy (UBM) at the sclerotomy sites between 30 and 40 days after surgery, once the tamponade had completely disappeared. Results In total, 349 sclerotomies (86.2%) of 99 patients were non-sutured while 56 sclerotomies (13.8%) of 36 patients were sutured at the end of the surgical procedure. Among the 36 patients with sutured sclerotomies, 15 out of 36 (41.6%) had at least two sclerotomies sutured. All the sclerotomy sites were evaluated (405 sclerotomies). Sclerotomy suture was significantly associated with a less aggressive pattern of vitreal incarceration (OR: 0.16, 95% CI: 0.07-0.35, p < 0.001). Compared to preoperative values, day 1 post operative IOP was not significantly different in patients with sutured sclerotomies, while patients with non-sutured sclerotomies had a significantly lower day 1 post operative IOP. Conclusions In 25-gauge macular surgery, UBM evaluation documented a higher rate of postoperative vitreous incarceration in the non-sutured sclerotomies, confirming the previously postulated role of the residual vitreous, left at the end of the surgery, in closing the sclerotomy site.
