BACKGROUND: The aim of this work was to compare the efficacy of intravitreal dexamethasone implant (Ozurdex) and intravitreal ranibizumab (Lucentis) in the treatment of macular edema (ME) caused by retinal vein occlusion (RVO). METHODS: Thirty-two ME cases treated with Ozurdex and 32 ME cases treated with ranibizumab were enrolled, with 26 central (C)RVO and 6 branch (B)RVO subjects in each group. We compared the results of best-corrected visual acuity (BCVA), central retinal thickness, number of injections, and intraocular pressure (IOP) at 1, 2, 3, and 6 months after injection...

BACKGROUND AND OBJECTIVES: To study the effect of early switching to ranibizumab (Lucentis; Genentech, South San Francisco, CA) or aflibercept (Eylea; Regeneron, Tarrytown, NY) in cases of diabetic macular edema (DME) that have shown no response to bevacizumab (Avastin; Genentech, South San Francisco, CA). PATIENTS AND METHODS: A retrospective study involving 59 eyes of 45 patients with DME previously treated with bevacizumab. Patients were switched either to ranibizumab or aflibercept...

A novel and versatile approach to tune photoluminescence and electroluminescence by in situ controlled thermal deprotonation is presented. This methodology, based on a single organic π-conjugated material (pyrene derivative), allows the manufacturing of Organic Light-Emitting Diodes (OLEDs) prototypes by solution methods with controlled tunable emission ranging from the orange (protonated form of the dye) to the blue (pristine or deprotonated form). While several protonation/deprotonation cycles can be performed on thin films, for the devices only one cycle is possible so that their use as anti-fraud labels can be envisaged...

We analyzed the effects of anti-vascular endothelial growth factor (VEGF) drugs combined with photodynamic therapy (PDT) in the treatment of age-related macular degeneration (AMD). Ninety-six cases (192 eyes) of AMD were included in this study and randomly divided into the observation group and control group (n=48 cases per group). The control group was administered the treatment of Lucentis intravitreal injection alone and the observation group was administered Lucentis combined with PDT. The therapeutic effects were compared...

This Industry Update covers the period from 1 October through to 31 October 2016, and is based on information sourced from company press releases, scientific literature, patents and various news websites. The month saw several news items covering drug-delivery devices, including a new sensor to monitor and support the use of inhalers; launch in the UK of a new autoinjector for Cimzia(®), UCB's rheumatoid arthritis drug; and approval of Roche's Lucentis(®) in a prefilled syringe. Research was also published to show the value of continuous blood pressure monitoring in dementia management...

A former 24-week-old premature infant was treated with intravitreal ranibizumab (Lucentis; Genentech, South San Francisco, CA) in one eye and conventional laser in the other eye for aggressive posterior retinopathy of prematurity in both eyes. Fluorescein angiography performed at 149 weeks of age showed persistent avascularity of the temporal peripheral retina in the ranibizumab-treated eye. This case report confirms the need for long-term follow-up of patients treated with ranibizumab monotherapy. [Ophthalmic Surg Lasers Imaging Retina...

The synthesis and characterization of three 5-π-delocalized-donor-1,3-di(2-pyridyl)benzenes is reported along with that of their related cyclometallated platinum(ii) complexes and N,N-dimethylated iodide salts. The second-order nonlinear optical (NLO) properties of all the compounds have been determined by the Electric Field Induced Second Harmonic generation technique, showing how the μβEFISH absolute value of 1,3-di(2-pyridyl)benzenes can be tuned by the nature of the substituent on position 5 of the central benzene ring, and greatly increased by cyclometallation to Pt or by N-methylation...

BACKGROUND AND OBJECTIVE: To evaluate the surgical outcome of type 1 retinopathy of prematurity (ROP) after intravitreal ranibizumab (IVR) (Lucentis; Genentech, South San Francisco, CA) treatment. PATIENTS AND METHODS: This was a prospective case series. Premature infants with treatment-requiring ROP who received IVR injections from 2013 to 2015 were included. RESULTS: Twenty-two eyes of 12 children were included in the study. Complete resolution of ROP after a single IVR was noted in 73% of eyes...

BACKGROUND: We present an interesting case of bilateral retinitis pigmentosa (RP)-associated cystoid macular oedema that responded on two separate occasions to intravitreal injections of aflibercept, despite previously demonstrating only minimal response to intravitreal ranibizumab. This unique case would support a trial of intravitreal aflibercept for the treatment of RP-associated cystoid macular oedema. CASE PRESENTATION: A 38-year-old man from Dubai, United Arab Emirates, presented to the UK with a 3-year history of bilateral RP-associated cystoid macular oedema...

BACKGROUND: Vision-related quality of life (vrQoL) is advancing more and more into the focus of interest in ophthalmological clinical research. However, to date only little information is available about vrQoL from large non-interventional studies in terms of "real-world evidence". The purpose of this investigation was to describe baseline VFQ-25 visual function scores, to evaluate whether they differ from previous phase III clinical trials, to determine which contributing factors (e...

The anti-vascular endothelial growth factor (VEGF) agents such as ranibizumab (Lucentis®) and aflibercept (EyLea®) are currently used as monthly or bimonthly intravitreal injections to treat potentially retinal diseases such as wet age-related macular degeneration (AMD) or diabetic macular edema (DME). Because of the complications associated with repeated intra-vitreal injections, there is considerable interest in developing a sustained delivery system. The purpose of this study was to examine the stability of both therapeutic proteins under physiological conditions as well as when incorporated into drug delivery systems (DDS)...

OBJECTIVE: To evaluate the utility of dexamethasone intravitreal implant (DXI; Ozurdex; Allergan, Irvine, Calif.) in combination with ranibizumab (Lucentis; Novartis Pharma AG, Basel, Switzerland) versus ranibizumab monotherapy on visual acuity (VA) and anatomical outcomes in a neovascular age-related macular degeneration (nAMD) cohort. DESIGN: Multicentred, single-blinded, pilot randomized control trial. PARTICIPANTS: Ten patients 50 years or older with subfoveal choroidal neovascularization secondary to AMD were randomized to receive DXI in combination with ranibizumab (group 1) or ranibizumab alone (group 2) after a 3-month ranibizumab loading period...

Ocular neovascularization (NV) is the primary cause of blindness in many ocular diseases. Large molecular weight anti- vascular endothelial growth factor (VEGF) protein drugs, such as Avastin and Lucentis, have saved the vision of millions. However, approximately 20-30% of patients respond poorly to anti-VEGF treatment. We found that artesunate (ART), a small molecular derivative of artemisinin, had a significant inhibitory effect on ocular NV by downregulating the expression of VEGFR2, PKCα, and PDGFR. ART significantly inhibited retinal NV in rabbits and macular edema in monkeys with greater anterior chamber penetrability and more durable efficacy than Avastin...

PURPOSE: The purpose of this study was to assess whether specific characteristics of spectral domain optical coherence tomography (SD-OCT) affect structural and functional outcomes and number of injections needed in ranibizumab (0.05 mL of 10 mg/mL Lucentis solution)-treated wet age-related macular degeneration (AMD) patients. PATIENTS AND METHODS: This retrospective case series included 62 newly diagnosed wet AMD patients treated with three monthly intravitreal ranibizumab injections followed by monthly follow-up and pro re nata retreatment...

Diabetic retinopathy (DR) is the leading cause of blindness among working-age adults. DR often leads to diabetic macular edema (DME), which often goes unnoticed until a patient presents with vision loss. However, treatment options and data for DME are continually improving. We know that vascular endothelial growth factor (VEGF) plays a key role in DME progression; therapies that act by inhibiting VEGF production seem to improve visual acuity in patients with DME. Of the anti-VEGF therapies available, two have been approved by the U...
