Abstract Background To evaluate changes in anterior segment morphology on anterior segment optical coherence tomography (AS-OCT) following pars plana vitrectomy (PPV) without tamponade. Methods Patients who underwent PPV without tamponade for epiretinal membrane were evaluated. Eligible patients underwent intraocular pressure (IOP) measurement and AS-OCT preoperatively as well as 1 month and 6 months post-operatively. Anterior chamber width (ACW), anterior chamber depth (ACD), trabecular iris angle (TIA), angle opening distance at 500 and 750 µm (AOD), and trabecular iris space area at 500 and 750 µm (TISA) at four quadrants were recorded and analyzed. Additionally, the mean values of TIA (MTIA), AOD (MAOD), and TISA (MTISA) for each eye (mean of four quadrants) were analyzed. Results 23 patients completed the study. The mean age of participants was 56.4 ± 3.6 years of age and 13/23 (56%) were female. Mean IOP of patients was 18.1 ± 1.1, 18.3 ± 1.1, and 18.1 ± 1.2 preoperatively,1 month post-operatively, and 6 months post-operatively, respectively. (p = 0.83). No difference was detected post-operatively in measurements of ACW, ACD, MTIA, MAOD500, MAOD750, MTISA500, and MTISA750. Conclusion Pars plana vitrectomy without tamponade was not associated with changes in anterior chamber morphology.

Introduction: Vitrectorhexis is an alternative for manual continuous curvilinear capsulorhexis originally developed for paediatric cataract surgery. The aim of our study was the evaluation of the technique in adult patients with penetrating ocular injury and traumatic cataracts. Methods: Eight eyes of 8 patients (23–41 years, all males) had penetrating mechanical corneal trauma. Anterior lens capsule was penetrated in all cases and additional posterior capsule defect in five cases. Intraocular foreign body was detected in one case in the crystalline lens and in two cases in the posterior segment. Standard 23G infusion cannula and vitreous cutter were applied to perform anterior capsule opening, removal of lens material, anterior vitrectomy and pars plana vitrectomy if needed. No phacoemulsification or irrigation/aspiration probe was used. Results: Vitrectorhexis could be performed in 7 out of 8 cases with the preservation of peripheral anterior capsule; primary implantation of posterior chamber intraocular lens was possible in all cases (in the bag in three eyes and into the sulcus in five eyes). Anterior chamber was stable in all cases intraoperatively, and no dropped nucleus or lens fragment loss was observed. Surgery was combined with pars plana vitrectomy in three cases, with foreign body removal (when necessary). No postoperative complication occurred. Conclusion: Vitrectorhexis was found to be an effective and safe alternative method in the management of complex anterior segment trauma cases. With its use, traditional cataract surgical devices can be substituted and additional benefits of vitreous cutter can be utilized in selected cases, especially in young adults.

AbstractA 57-year-old otherwise healthy male presented to our department seven days following uneventful pars-plana vitrectomy with gas tamponade for a superior bullous retinal detachment in the left eye. Ophthalmic examination revealed anterior segment inflammation with hypopyon and fibrinous exudate. Intra-ocular pressure was 28 mmHg. Posterior segment evaluation was difficult to assess due to the presence of anterior capsule opacification and gas bubble. A Toxic Anterior Segment Syndrome was suspected, and the patient was treated with topical and oral corticosteroid medication in combination with anti-glaucomatous therapy. On follow-up, anterior segment inflammation and ocular hypertension improved. On day ten post-operatively, ocular ultrasonography demonstrated lens material inferiorly with attached retina. The final diagnosis of posterior lens nucleus dislocation with lens-induced uveitis was retained. The patient underwent an uneventful second vitrectomy with aspiration of the dislocated lens nucleus and sulcus three piece-lens implantation. On last follow-up, visual acuity was 20/50 with no relapsing of ocular inflammation and the retina remained reattached.

Objective. To evaluate the morphological changes of the anterior segment using ultrasonic biomicroscopy (UBM) imaging in pseudophakic patients who underwent pars plana vitrectomy (PPV) with silicone oil or gas (C3F8) internal tamponade agent injection.Method. This prospective study included pseudophakic patients with planned PPV, divided into two groups according to internal tamponade agent: those in which silicone oil was used (n=27, Group 1) and those in which gas (C3F8) was used (n=24, Group 2). UBM measurements were performed in the supine position before and one week after surgery.Results. In patients of Group 1, postoperative trabecular meshwork-ciliary process distance (T-CPD) and iris-ciliary process distance (I-CPD), according to preoperative values, were found to be statistically significantly reduced, and postoperative mean value of scleral thickness (ST) and intraocular pressure (IOP), according to preoperative value, was found to be statistically significantly increased. In patients of Group 2, postoperative mean values of anterior chamber depth (ACD), ciliary body thickness (CBT), T-CPD, I-CPD, and IOP, according to preoperative values, were found to be statistically significantly reduced. Preoperatively, in Group 2 patients, according to Group 1 patients, TIA and IOP were found to be statistically significantly increased. Preoperative and postoperative IOP between the measured parameters with UBM showed no statistically significant correlation.Conclusions. Gases cause more morphological changes in the anterior segment structures. It is thought that complications such as increased intraocular pressure can be seen more frequently for this reason.
