BACKGROUND AND OBJECTIVE: Microincisional vitrectomy surgery has improved outcomes for vitrectomies; however, wound closure complications remain an important concern. The authors introduce a technique to improve transconjunctival wound closure in vitrectomy surgery. PATIENTS AND METHODS: The authors evaluated the efficacy of porcine collagen plugs on stopping leakage from sclerotomy test sites in vitro and in vivo and assessed wound site healing with histology samples...

PURPOSE: This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. METHODS: The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. RESULTS: From the preoperative OCT, normal fovea with/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all p < 0...

A 60-year-old female came to our hospital with defective vision due to persistent diabetic macular edema and was treated with intravitreal ozurdex implant in the right eye. Three days later, the patient presented with diminution of vision, ocular pain, congestion, and hypopyon with no fundus view. B-scan ultrasonography showed vitritis, and diagnosis of endophthalmitis was made. Subsequently, 25-gauge pars plana vitrectomy was performed along with intravitreal vancomycin and amikacin and removal of implant...

PURPOSE: To determine whether internal limiting membrane (ILM) peeling during pars plana vitrectomy for rhegmatogenous retinal detachment reduces the incidence of epiretinal membrane (ERM) formation. METHODS: In this retrospective study, preoperative, intraoperative, and postoperative data from all eyes undergoing pars plana vitrectomy for rhegmatogenous retinal detachment between January 2007 and December 2013 was analyzed. All cases with at least 1-year of follow-up were included...

Purpose: The purpose of this study was to study the incidence and factors influencing retinal displacement in eyes treated for rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) and gas or silicone oil. Methods: This was a prospective observational case series. One hundred twenty-five eyes with macula-off RRD from 125 patients underwent 25-gauge PPV at two vitreoretinal institutional practices. Eyes without proliferative vitreoretinopathy (PVR) or PVR grade A were tamponated with sulfur hexafluoride (SF6) gas, whereas eyes with PVR grade B received 1000 centistokes silicone oil (SO)...

Purpose Postoperative endophthalmitis caused by Enterococcus faecalis often results in poor visual outcome due to retinal destruction. We evaluated the virulence factors of Enterococcus faecalis clinical isolates and analyzed their relationship with retinal destruction and poor visual outcomes in postoperative bacterial endophthalmitis (PBE) following cataract surgery. STUDY DESIGN: Retrospective. METHODS: E. faecalis isolates from nine acute-onset PBE cases were examined using pulsed-field gel electrophoresis of genomic DNA, plasmid isolation and pheromone response experiments...

REVIEW
Hiroki Kaneko, Hiroko Terasaki
Even with a high surgical success rate for retinal detachment and proliferative vitreoretinopathy (PVR) supported by the robust improvement in vitrectomy surgery and its related devices, certain questions still remain for the pathogenesis and treatment of PVR. One of the important biological events in PVR is epithelial-mesenchymal transition (EMT) of the retinal pigment epithelial (RPE) cells. MicroRNAs are noncoding, small, single-strand RNAs that posttranscriptionally regulate gene expression and have essential roles in homeostasis and pathogenesis in many diseases...

The purpose of this study was to compare steroid hormone concentration levels in the vitreous and serum of vitreoretinal disease patients to elucidate the possibility of neurosteroid production in the retina. Serum and vitreous samples were collected from vitrectomy patients, and estradiol (E2) and testosterone (T) concentrations were measured using electro-chemiluminescence immunoassay. We measured E2 in epiretinal membrane (ERM, n = 14), macular hole (MH, n = 18), proliferative diabetic retinopathy (PDR, n = 20), and retinal detachment (RD, n = 19) cases, and T in ERM (n = 14), MH (n = 17), PDR (n = 13), and RD (n = 17) cases...

PURPOSE: To assess the impact of sequential and combined surgery [cataract surgery and 23-gauge pars plana vitrectomy (PPV) with peeling] on corneal endothelium cell density (CED) and corneal biomechanical characteristics. METHODS: Phakic eyes with epiretinal membrane (ERM) were prospectively allocated to (i) cataract surgery and subsequent PPV (CAT group), (ii) PPV and subsequent cataract surgery (VIT group) or (iii) phacovitrectomy (COMBI group).

BACKGROUND The aim of this study was to compare the efficacy of air and perfluoropropane (C3F8) combined with vitrectomy to treat myopic foveoschisis (MF). MATERIAL AND METHODS A retrospective comparison of a consecutive series of surgical patients was performed. Ninety-seven eyes of 91 patients with MF were assigned to undergo 23G vitrectomy. After internal limiting membrane (ILM) peeling, the vitreous cavity was filled with air in 48 eyes of 45 patients (Air Group). Fluid-air exchange was performed in 49 eyes of 46 patients (C3F8 Group) followed by an injection of 14% C3F8...

Today, the widespread use of laser instruments in various fields has resulted in many accidental retinal injuries. Here we describe a rare clinical case of full-thickness macular hole (MH) and focal choroidal excavation (FCE) caused by a 1064-nm Q-switched Nd:YAG laser. After pars plana vitrectomy and the following 14 months, consecutive optical coherence tomography imagings showed closure of the MH. Visual acuity improved even in the absence of the outer retina and in the presence of FCE. We speculate that different focusing effects of the unexpected Nd:YAG laser which target different levels of retinal tissue generates diverse prognosis...

PURPOSE: To evaluate the macular choroidal thickness (CT) of eyes subjected to pars plana vitrectomy (PPV) whether or not combined with encircling scleral buckling (ESB) surgery for primary rhegmatogenous retinal detachment repair at 6 months or more after surgery. METHODS: This observational study included: 15 eyes (15 patients) submitted to combined ESB+PPV; 15 eyes submitted to PPV and their respective 30 normal fellow eyes (FE). Two 6mm lineal perpendicular optical coherence tomography B-scans centred on the fovea with enhanced depth imaging were performed on each eye...

Surgical manoeuvres for the treatment of retinal vein occlusion peaked at the turn of the century. The first overwhelming reports could not be confirmed in prospective studies. Furthermore, the functional success was never comparable to intravitreal drug therapy, and the manoeuvres are no longer used in clinical routine. The procedures, the surgical theory and the criticism on vitrectomy, radial optic neurotomy (RON), retinal endovascular fibrinolysis (REVL) and arteriovenous dissection (AVD) will be discussed in this paper...

PURPOSE: To evaluate the change of residual volume of eye drop after instillation in patients with 23-gauge microincision vitrectomy surgery (MIVS). METHODS: Patient who were treated 23-gauge MIVS from November 2014 to July 2015 were included. The residual volume was defined as the amount of remnant eye drop in patient's eyes after instillation, calculated as the difference between instillation volume and spilled volume of eye drop. Calculation of residual volume of eye drop was performed one day before surgery, and daily from postoperative day 1 to day 5...

PURPOSE: To compare vascular displacement in the macula after surgical closure of idiopathic macular hole (MH) after single-layered inverted internal limiting membrane (ILM) flap technique and conventional ILM removal. METHODS: This retrospective study included patients who underwent either vitrectomy and ILM removal only or vitrectomy with single-layered inverted ILM flap for idiopathic MH larger than 400 μm from 2012 to 2015. A customized program compared the positions of the retinal vessels in the macula between preoperative and postoperative photographs...
