Aims: To analyse the changes in endothelial cell density (ECD) after pars plana vitrectomy (PPV) and to identify the factors implicated. Patients and Methods: This was a prospective, consecutive, and non-randomised, case-control study. All 23-gauge vitrectomies were performed by a single surgeon at a tertiary centre. ECD was measured at baseline before surgery and on postoperative Days 30, 90, and 180. The fellow eye was used as the control eye. The primary outcome was a change in ECD after PPV. Results: Seventeen patients were included in this study. The mean age of the patients was 65 years.

Purpose: This retrospective study recorded intraoperative findings during silicone oil removal and postoperative anatomical outcomes comparing endoscopy-assisted pars plana vitrectomy (E-PPV) vs pars plana vitrectomy (PPV) alone after proliferative vitreoretinopathy (PVR)-related retinal detachment (RD) repair. Methods: This single-center retrospective study included patients who underwent PPV for silicone oil removal after RD with PVR from July 2009 to January 2017. Patients with diabetic tractional RD, history of trauma, uveitis, or endophthalmitis were excluded. After 2013, an endoscopic vi

Introduction: Rhegmatogenous retinal detachment (RRD) is one of the leading causes of vision loss worldwide. Retinal reattachment is the main target of RRD management. Pars plana vitrectomy (PPV) is one of the surgical approaches to reattach the retina by removing the vitreous gel and replacing it with tamponades. Several tamponades used in PPV may cause an alteration of intraocular pressure (IOP).

Pars plana vitrectomy (PPV) stands as a valuable treatment option in these cases, but its application in eyes with such severely impaired chorioretinal architectures remains controversial. Furthermore, the spreading of gene therapy and the increasing use of retinal prostheses will end up in a marked increase in demand for PPV surgery for IRD patients.

Cataract surgery causes changes in intraocular conditions that are a risk factor for retinal detachment. One of the conditions that can occur during cataract surgery is posterior capsule rupture which can increase the risk of pseudophakic retinal detachment (PRD). PRD examination is often obstructed by opacification of the posterior capsule, a reflection of the intraocular lens (IOL), or poor mydriasis. Scleral buckle, pneumatic retinopexy, and primary pars plana vitrectomy, with or without a combination of the scleral buckle, are surgical techniques used in the management of PRD patients. Ana
