AIMS: To review clinical experience, efficacy, and safety of transluminal Nd:YAG laser embolectomy/embolysis (TYE) for retinal artery occlusion. METHODS:  Electronic databases were searched for all published clinical studies and case-reports reporting on TYE in central (CRAO) or branch (BRAO) retinal artery occlusion. Individual patient data was evaluated in a weighted pooled analysis. RESULTS: Sixty-one cases were reported, 47 with BRAO and 14 with CRAO...

Purpose: To evaluate a self-assembling peptide gel as a potential vitreous substitute. Methods: PanaceaGel SPG-178, a self-assembling peptide gel, was diluted with distilled water and a balanced salt solution to achieve a final peptide concentration of 0.1%. The gel's refractive index, visible light transmission rate, and rheologic properties were investigated. The gel's biocompatibility was evaluated by examining the cellular viability (live and dead staining) and proliferation rate (alamarBlue assay)...

PurposeSafe and reproducible delivery of gene therapy vector into the subretinal space is essential for successful targeting of the retinal pigment epithelium (RPE) and photoreceptors. The success of surgery is critical for the clinical efficacy of retinal gene therapy. Iatrogenic detachment of the degenerate (often adherent) retina in patients with hereditary retinal degenerations and small volume (eg, 0.1 ml) subretinal injections pose new surgical challenges.MethodsOur subretinal gene therapy technique involved pre-operative planning with optical coherence tomography (OCT) and autofluorescence (AF) imaging, 23 G pars plana vitrectomy, internal limiting membrane staining with Membrane Blue Dual (DORC BV, Zuidland, Netherlands), a two-step subretinal injection using a 41 G Teflon tipped cannula (DORC) first with normal saline to create a parafoveal bleb followed by slow infusion of viral vector via the same self-sealing retinotomy...

PURPOSE: To evaluate whether retropupillary fixation of the iris-claw intraocular lens (IOL) is a safe and effective treatment option in children with large lens subluxations. METHODS: Fourteen eyes of children between the ages of 8-17 years with lens subluxations more than 7 clock hours underwent pars plana lensectomy-vitrectomy with implantation of the iris-claw IOL in the retropupillary position as a primary procedure. The best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial count (EC) and the lens position using ultrasound biomicroscopy (UBM) were assessed pre- and postoperatively...

PURPOSE: To describe the safety and efficacy of a technique to close large thickness macular holes. METHODS: A consecutive retrospective interventional case series of 16 patients with macular holes greater than 650 microns in "aperture" diameter were included. The technique involves vitrectomy, followed by internal limiting membrane peeling. The macula is detached using subretinal injection of saline. Fluid-air exchange is performed to promote detachment and stretch of the retina...

INTRODUCTION: In 2001 a survey among retinal surgeons regarding the treatment of rhegmatogenous retinal detachment either with scleral buckling methods or primary vitrectomy was performed. Due to the technical progress of vitrectomy and observational systems, it seemed appropriate to renew and update this survey supplemented with current aspects. METHODS: In this study 78 vitreoretinal surgeons from German-speaking countries were surveyed via an anonymous online questionnaire on their treatment decisions for defined retinal detachment constellations...

REVIEW
H Hoerauf, B Kirchhof
Elective surgery of the vitreoretinal interface is currently the most common reason for vitrectomy in Germany. The evaluation and correct interpretation of spectral domain optical coherence tomography (SD-OCT) images is of great importance but the indications for vitrectomy in macular surgery should be based more on patient symptoms and not only the OCT findings. Watchful waiting is highlighted as an alternative therapeutic option in individual patients. This article addresses a number of aspects and discrepancies between findings and patients' level of suffering based on binocular symptoms...

PURPOSE: To evaluate the outcome of 23 G PPV and ILM peeling with 14% C3F8 compared with silicone oil tamponade in cases of TMHs without spontaneous closure. METHODS: A retrospective comparative study included 33 eyes with TMHs; 7 eyes healed spontaneously, and the remaining 26 eyes have been treated with PPV and ILM peeling. Silicone oil was used as a tamponade for children or adults who refused to adopt face-down position (10 cases). In all other cases (16 cases), 14% C3F8 was used...

The aim of the present study was to compare the effectiveness of 25G vitrectomy to standard 20G vitrectomy for treatment of Terson syndrome under Resight non-contact wide-angle lenses. This was a case-control study of 20 patients with Terson syndrome (study group) that underwent 25G vitrectomy under Resight non-contact wide-angle lenses, with those of 20 matched patients that underwent 20G vitrectomy (control group). Medical records were reviewed from between July 2011 and October 2013. Data included results of the Early Treatment Diabetic Retinopathy Study examination, ophthalmology B-scan ultrasonography and fundus photography...

A 78-year-old immunocompetent man presented with a 3-month history of painless decreased vision and panuveitis with a macular lesion presumed to be due to endogenous endophthalmitis. He had been treated with systemic, intravenous, and intravitreal antibiotics and antifungal agents as well as intravitreal steroids. A culture from a prior vitrectomy had grown a single colony of Aspergillus thought to be a contaminant. The macular lesion enlarged and caused a tractional retinal detachment. The patient underwent surgery including resection of what appeared to be an invasive retinal aspergilloma, from which polymerase chain reaction and histopathology confirmed Aspergillus fumigatus...

BACKGROUND AND OBJECTIVE: To describe morphologic characteristics, surgical outcomes, postoperative preferred retinal loci (PRL), and fixation stability of epiretinal membranes (ERMs) in young patients. PATIENTS AND METHODS: This retrospective study analyzed 43 eyes of 41 young patients (age range: 0.8 years to 28 years) with ERMs, which were divided into two groups: secondary ERMs (SERMs; n = 28) and idiopathic ERMs (IERMs; n = 13). All 43 eyes underwent 25-gauge vitrectomy and membrane peeling...

INTRODUCTION: The purpose of this study was to evaluate baseline and postoperative factors affecting outcomes after vitrectomy for diabetic macular edema (DME) using optical coherence tomography (OCT). METHODS: Vitrectomy combined with inner limiting membrane (ILM) peeling and additional laser photocoagulation therapy was performed on 36 eyes of 30 DME patients. Evaluations included the logarithm of the minimal angle of resolution (logMAR), best-corrected visual acuity (BCVA) and OCT parameters at baseline and 1, 3, 6, and 12 months postoperatively...

REVIEW
Deepak Gupta, Jared Ching, Paul E Tornambe
The successful detection of retinal breaks is a critical step in rhegmatogenous retinal detachment (RRD) surgery in order to prevent persistent/recurrent RRDs. Not all retinal breaks causing retinal detachments are obvious. Retinal breaks may be obscured due to opacities that are either anterior-segment related, lens related or posterior-segment related. Rules to identify breaks based on sub-retinal fluid (SRF) configuration are more difficult to apply in pseudophakic, aphakic, encircled eyes, and eyes with repeat detachments and those with proliferative vitreoretinopathy (PVR)...

PurposeSeverely subluxated crystalline lenses pose a difficult situation to anterior segment surgeons and can only be managed surgically by removal of the lens as well as the capsular bag. Several techniques have been described in literature for the management of such cases. We describe a modified technique of endocapsular lens aspiration by the limbal route for lens extraction through small incisions on the cornea.Patients and methodsThirty-two eyes of 16 consecutive patients with severely subluxated crystalline lenses were recruited in the study...
