PURPOSE: To investigate the short-term outcomes after intravitreal injection of ziv-aflibercept in the treatment of choroidal and retinal vascular diseases. METHODS: Thirty-four eyes of 29 patients with age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusion (RVO) received a single dose intravitreal injection of 0.05 ml ziv-aflibercept (1.25 mg). Visual acuity, spectral domain optical coherence tomography (SD-OCT) activity, and possible side effects were assessed before and at 1 week and 1 month after the intervention...

Retinal vein occlusion (RVO) is a common vascular disease of retina; however, the pathomechanism leading to RVO is not yet clear. In general, increasing age, hypertension, arteriosclerosis, diabetes mellitus, dyslipidemia, cardiovascular disorder, and cerebral stroke are systemic risk factors of RVO. However, RVO often occur in the unilateral eye and sometimes develop in young subjects who have no arteriosclerosis. In addition, RVO show different variations on the degrees of severity; some RVO are resolved without any treatment and others develop vision-threatening complications such as macular edema, combined retinal artery occlusion, vitreous hemorrhage, and glaucoma...

A concept integrating sampling and protein digestion is introduced here combining fast and simple fabrication by wax printing on filter paper with trypsin immobilized polymer beads. The paper reactors showed promising results with a high degree of protein digestion within fifty minutes in model protein mixtures as well as in human blood. The model protein mixture was used for the evaluation of performance both with and without a reduction and alkylation step. The paper reactors without reduction and alkylation showed between 46% and 75% protein sequence coverage and between five and 20 high confidence peptides (one and five zero missed cleavage peptides, respectively)...

AIM: The aim of this study was to evaluate overall survival (OS) and prognostic factors in patients ineligible for chemotherapy who were treated with a hyperfractionated accelerated schedule with simultaneous integrated boost. MATERIAL AND METHODS: From May, 2008, to April, 2013, 122 patients with locally advanced nonmetastatic squamous laryngeal (14%), hypopharyngeal (30%), oropharyngeal (30%), and oral cavity (27%) cancer were treated at our institution. The median age, Karnofsky Performance Status (KPS), and gross tumor volume (GTV) of the patients were 63 years (range, 46-87 years), 80% (range, 50-100%), and 46 ml (range, 5-250 ml), resp...

PURPOSE: To evaluate the anatomical and functional outcome of intravitreal dexamethasone implant for macular edema secondary to central (C) or branch (B) retinal vein occlusion (RVO) in patients with persistent macular edema (ME) refractory to intravitreal antivascular endothelial growth factor (VEGF) treatment compared to treatment naïve patients and to dexamethasone-refractory eyes switched to anti-VEGF. METHODS: Retrospective, observational study including 30 eyes previously treated with anti-VEGF (8 CRVO, 22 BRVO, mean age 69 ± 10 yrs), compared to 11 treatment naïve eyes (6 CRVO, 5 BRVO, 73 ± 11 yrs) and compared to dexamethasone nonresponders (2 CRVO, 4 BRVO, 69 ± 12)...

OBJECTIVE: Functional cardiac ultrasound measures are used clinically and in trials for assessing the haemodynamic status of newborn infants. Superior vena cava (SVC) flow and right ventricular output (RVO) are established measures of systemic blood flow on the first postnatal day. The objective was to assess image quality and interobserver agreement of these measures in preterm infants enrolled in a randomised trial of immediate versus delayed cord clamping. DESIGN AND SETTING: Image quality and interobserver agreement for SVC flow, RVO and ductus arteriosus (DA) size were assessed on measurements taken at 3-6, 6-12 and 20-28 hours for the first 10 infants enrolled at each of four sites (total 40)...

To evaluate the risk of retinal vein occlusion (RVO) development after primary open-angle glaucoma (POAG) and the risk of POAG development after RVO, we conducted a nationwide, population-based 11-year longitudinal study. National registry data were collected from the Korean National Health Insurance Research Database, comparing 1 025 340 (~2.2%) subjects who were selected from 46 605 433 Korean residents in 2002. Each sampled patients was tracked until 2013. POAG developed in 0.92% of the RVO group (n = 6 826) and in 0...

AIM: We aimed to evaluate the 1-year efficacy and safety of low-frequency intravitreal bevacizumab in the treatment of macular edema due to retinal vein occlusions (RVOs). METHODS: The study comprised an interventional prospective study of patients with macular edema due to central retinal vein occlusion (CRVO) or branch retinal vein occlusion, followed for 12 months. Treatment-naïve patients with reduced best-corrected visual acuity (BCVA) and central macular thickness (CMT) of at least 250 μm received intravitreal injection of bevacizumab...

BACKGROUND: Patients with retinal vascular occlusion disease have an increased risk for ischemic stroke and share some risk factors with cerebrovascular disease. The purpose of this study was to analyze the prevalence of atrial fibrillation (AF) in subjects with retinal vascular occlusive disease and anterior ischemic optic neuropathy and to compare these data to an ischemic stroke group. METHODS: Prospective, observational single-center trial. Subjects with retinal artery occlusion (RAO), retinal vein occlusion (RVO) and anterior ischemic optic neuropathy (AION) were included...

OCT has revolutionized the practice of ophthalmology over the past 10-20 years. Advances in OCT technology have allowed for the creation of novel OCT-based methods. OCT-Angiography (OCTA) is one such method that has rapidly gained clinical acceptance since it was approved by the FDA in late 2016. OCTA images are based on the variable backscattering of light from the vascular and neurosensory tissue in the retina. Since the intensity and phase of backscattered light from retinal tissue varies based on the intrinsic movement of the tissue (e...

PURPOSE: The purpose of this study was to report a rare case of subretinal lodgement of Ozurdex(®) implant (Allergan Inc., Irvine, CA, USA) and its effect on macular edema in a case of central retinal vein occlusion (RVO). METHODS: A rare complication of subretinal lodgement of Ozurdex(®) implant without retinal perforation was encountered in a case of RVO with intractable macular edema. As associated retinal perforation was not noted, no intervention was done...

IMPORTANCE: In Australia, knowledge of the epidemiology of retinal vein occlusion (RVO) remains scarce due to a paucity of recent population-based data. The National Eye Health Survey (NEHS, 2015-16) provides an up-to-date estimate of the prevalence of RVO in non-Indigenous and Indigenous Australian adults. BACKGROUND: To determine the prevalence and associations of retinal vein occlusion (RVO) in a national sample of Indigenous and non-Indigenous Australian adults...

Retinal artery occlusion (RAO) should be evaluated as an emergency and can be seen as an ocular analogue to the cerebral apoplex. Both have the same arteriosclerotic risk factors, which are also responsible for cardiac, circulatory and cerebrovascular diseases. That is why an intensive interdisciplinary clarification is necessary to recognize possible comorbidities in time and, if necessary, to treat them. The current therapeutic possibilities of an acute RAO are very limited in their efficiency regarding visual improvement...

Purpose: To demonstrate the utility of a novel in vivo molecular imaging probe, HYPOX-4, to detect and image retinal hypoxia in real time, in a mouse model of retinal vein occlusion (RVO). Methods: Retinal vein occlusion was achieved in adult mice by photodynamic retinal vein thrombosis (PRVT). One or two major retinal vein(s) was/were occluded in close proximity to the optic nerve head (ONH). In vivo imaging of retinal hypoxia was performed using, HYPOX-4, an imaging probe developed by our laboratory...
