INTRODUCTION: The objective of this study is to evaluate the influence of repeated intraocular dexamethasone implant (Ozurdex) injections on metabolic control in type 2 diabetic patients. METHODS: Retrospective study of 165 type 2 diabetic patients starting Ozurdex treatment who received no less than three consecutive injections. Glycated hemoglobin (HbA1c), serum creatinine, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides (TGs) were evaluated during 15 months of follow-up after Ozurdex treatment onset...

Neovascular age-related macular degeneration, characterized by abnormal choroidal neovascularization (CNV), is a major cause of blindness worldwide. Anti-vascular endothelial growth factor (VEGF) antibodies have demonstrated significant efficacy in improving visual acuity. TMAB001 is a new recombinant humanized rabbit anti-VEGF monoclonal antibody. It presents high activities in vitro studies. In the binding affinity assay, TMAB001 exhibited a high binding capability to VEGF with an affinity constant of 10(-11)M...

PURPOSE OF REVIEW: Although cataract surgery can effectively restore visual function in many patients with cataract, pseudophakic cystoid macular edema (PCME) remains an important cause of suboptimal visual acuity. The present review provides an overview of the current literature on the prevention and treatment of PCME. RECENT FINDINGS: Optimal prevention of PCME starts preoperatively with a personalized risk assessment. Diabetes mellitus, retinal vein occlusion, epiretinal membrane, macular hole, and uveitis are the most important risk factors for developing cystoid macular edema after cataract surgery...

Probucol is an antihyperlipidemic drug with potent antioxidant properties. Oxidative stress plays an important role in the pathogenesis of diabetic retinopathy. In this study, we aimed to investigate the protective effects of probucol against diabetes-induced retinal vascular dysfunction in a rat model of diabetes. Diabetes was induced by a combination of streptozotocin treatment and D-glucose feeding, and retinal vasodilator responses were assessed by measuring the diameter of retinal arterioles. The vasodilator effect of salbutamol, a β2-adrenoceptor agonist, on retinal arterioles was significantly diminished 2 weeks after the induction of diabetes...

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...

Purpose: Our previous experiments demonstrated that intravitreal injection of platelet-derived growth factor-AA (PDGF-AA) provides retinal ganglion cell (RGC) neuroprotection in a rodent model of glaucoma. Here we used PDGFRα-enhanced green fluorescent protein (EGFP) mice to identify retinal cells that may be essential for RGC protection by PDGF-AA. Methods: PDGFRα-EGFP mice expressing nuclear-targeted EGFP under the control of the PDGFRα promoter were used. Localization of PDGFRα in the neural retina was investigated by confocal imaging of EGFP fluorescence and immunofluorescent labeling with a panel of antibodies recognizing different retinal cell types...

A 77-year-old woman with exudative macular degeneration underwent bilateral intravitreal injections of "stem cells" at a clinic in Georgia. One month and 3 months after injection, she developed retinal detachments in the left and right eyes, respectively. Increased awareness within the medical community of such poor outcomes is critical so that clinics offering untested practices that have been shown to be potentially harmful to patients can be identified and brought under U.S. Food and Drug Administration oversight...

A 70-year-old woman presented with 20/200 visual acuity in the right eye. Multimodal imaging revealed tilted disc syndrome (TDS) with macular serous detachment (MSD) and pigmentary changes at the temporal margin of the optic disc. Subretinal fluid persisted after three monthly intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) injections and threshold focal laser photocoagulation. Subsequently, confluent subthreshold argon laser was applied over the entire area of retinal pigment epithelium (RPE) abnormalities, resulting in the resolution of subretinal fluid without recurrence through 3 years of follow-up...

BACKGROUND AND OBJECTIVE: To report the outcomes of decanted high-dose intravitreal triamcinolone acetonide (HD-IVTA) injection for treatment-resistant persistent macular edema (ME). PATIENTS AND METHODS: Seventy-seven eyes of 70 consecutive patients who failed prior treatments for persistent ME received as-needed HD-IVTA injections. Best-corrected visual acuity and central macular thickness (CMT) were assessed at all follow-up visits. RESULTS: Thirty-three eyes (42...

PURPOSE: To assess short-term functional and anatomical outcomes of refractory diabetic macular edema (DME) following a switch from ranibizumab or dexamethasone to aflibercept. METHODS: We included retrospectively eyes with persistent DME after at least 3 ranibizumab and/or one dexamethasone implant intravitreal injections (IVI). The primary endpoint was the mean change in visual acuity (VA) at month 6 (M6) after switching. RESULTS: Twenty-five eyes were included...

Retinitis pigmentosa (RP) comprises a heterogeneous group of inherited retinal diseases leading to blindness. The present study explored the protective effects of hydrogen rich saline (HRS) against the photoreceptor degeneration in the N-Methyl-N-nitrosourea (MNU) administrated rat, a pharmacologically induced RP model. The therapeutic effects of intraperitoneal (IP) and intravitreous (IV) injections of HRS on regional retina was quantified via topographic measurements. The MNU administrated rats received IV or IP injections of HRS, and then they were subjected to electroretinography, multi electrode array, histological and immunohistochemistry examinations...

PURPOSE: The aim of this study was to evaluate the efficacy of a treat-and-extend (TAE) regimen using intravitreal injection of aflibercept (IVA) for typical age-related macular degeneration (tAMD). METHODS: We retrospectively studied 61 treatment-naïve eyes with tAMD. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), number of injections, and complications during 2 years were evaluated. RESULTS: BCVA significantly improved by on average 0...

The objective of this study is to investigate the levels of vascular endothelial growth factor (VEGF) and other cytokines in aqueous humor of patients with idiopathic choroidal neovascularization (CNV) and their effects together with central retinal thickness (CRT) on the response to intravitreal injection of anti-VEGF antibody ranibizumab. This clinical study recruited 32 eyes from 32 patients with CNV under or besides fovea. VEGF, interleukin (IL)-6, IL-8, and monocyte chemoattractant protein (MCP)-1 levels were detected in aqueous humor (0...

REVIEW
Peter Bracha, Nicholas A Moore, Thomas A Ciulla, Darrell WuDunn, Louis B Cantor
The acute and chronic effects of repeated intravitreal anti-vascular endothelial growth factor (VEGF) injections on intraocular pressure (IOP) have not been fully characterized and the development of sustained ocular hypertension could adversely affect patients who are at risk of glaucomatous optic neuropathy. As expected, volume-driven, acute ocular hypertension immediately follows intravitreal injection, but this pressure elevation is generally transient and well-tolerated. Several medications have been investigated to limit acute ocular hypertension following anti-VEGF therapy, but the benefits of pretreatment are not conclusive...

PURPOSE: To compare two different initial dosing regimens of intravitreal ranibizumab used to treat myopic choroidal neovascularization. METHODS: A total of 61 eyes of 56 patients were treated: 26 eyes received a single injection followed by treatment pro re nata (1+ PRN), while 35 eyes first received 3 consecutive monthly injections (3+ PRN). RESULTS: The mean follow-up was 53 ± 16 months. The visual acuities were 51.9 ± 16.2 letters with 3+ PRN and 53 ± 22...
