We present the case of a 38-year-old Asian patient who reported vision loss of her left eye since 4 weeks. The funduscopy showed a choroidal tumor in the papillomacular bundle, which could be identified as a choroidal osteoma with secondary choroidal neovascularization (CNV). OCT angiography (OCT-A) detected abnormal flow in the choriocapillaris; the osteoma showed no flow in the OCT angiogram of the choroid level. Therefore, OCT-A can be a helpful adjuvant for diagnosis of CNV secondary to choroidal osteoma...

A potent anti-vascular endothelial growth factor (VEGF) biologic and a compatible delivery system were co-evaluated for protection against wet age-related macular degeneration (AMD) over a 6month period following a single intravitreal (IVT) injection. The anti-VEGF molecule is dimeric, containing two different anti-VEGF domain antibodies (dAb) attached to a human IgG1 Fc region: a dual dAb. The delivery system is based on microparticles of PolyActive™ hydrogel co-polymer. The molecule was evaluated both in vitro for potency against VEGF and in ocular VEGF-driven efficacy models in vivo...

We report a case of enucleation for painful blind eye secondary to recurrent bleeding from choroidal neovascularisation in an eye that was irradiated following presumed metastatic breast carcinoma to the choroid. A 58-year-old woman with a history of treated breast malignancy presented with haemophthalmus and intractable glaucoma in the right eye. One year previously she had presented with right vitreous haemorrhage with subretinal mass that had been irradiated given her history of breast carcinoma. Following irradiation, vitrectomy was performed to clear the blood...

BACKGROUND/AIMS: To compare the short-term efficacy of intravitreal aflibercept treatment according to the subtypes of polypoidal choroidal vasculopathy (PCV) based on indocyanine green angiography (ICGA). METHODS: Twenty-nine patients (29 eyes) with treatment-naïve subfoveal PCV were consecutively enrolled in this institutional study. The subjects were classified into two subtypes (type 1, polypoidal choroidal neovascularisation (CNV), 16 eyes; and type 2, idiopathic PCV, 13 eyes) based on the presence or absence of both feeder and draining vessels on ICGA...

Dynamic control of endothelial cell junctions is essential for vascular homeostasis and angiogenesis. We recently provided genetic evidence that ANGPTL4 is a key regulator of vascular integrity both during developmental and in hypoxia-induced pathological conditions. The purpose of the present study was to decipher the molecular mechanisms through which ANGPTL4 regulates vascular integrity. Using surface plasmon resonance and proximity ligation assays, we show that ANGPTL4 binds integrin αvβ3. In vitro and in vivo functional assays with Angptl4-deficient mice demonstrate that ANGPTL4-αvβ3 interaction is necessary to mediate ANGPTL4 vasoprotective effects...

PURPOSE: To describe optical coherence tomography angiography (OCTA) image artefacts in eyes with and without ocular pathologies. METHODS: The OCTA images of healthy subjects and patients with age-related macular degeneration, diabetic retinopathy and retinal vascular occlusions were retrospectively reviewed. All OCTA images were obtained using a swept-source OCTA instrument (Triton, Topcon). The frequency of various image artefacts including segmentation, banding, motion, projection, masking, unmasking, doubling of the retinal vessels, blink, stretching, out-of-window and crisscross artefacts was assessed...

Choroidal neovascularisation (CNV) is a major cause of visual loss and treatment options aim to halt progression and stabilise vision. We describe a 29-year-old woman who presented with blurred vision and distortion in her left eye while 26 weeks pregnant. She was diagnosed with idiopathic CNV and multiple treatment options were discussed. The patient did not want to undertake any risks from having an anti vascular endothelial growth factor agent during pregnancy. Therefore on discussion with the obstetric team, she elected to have early delivery at 32 weeks followed by a course of intravitreal bevacizumab...

INTRODUCTION: We present a case of enhanced S-cone syndrome (ESCS)-associated choroidal neovascularisation (CNV) treated successfully with intravitreal bevacizumab therapy. METHODS/CASE REPORT: A 14-year-old with a known retinal dystrophy presented with acute visual deterioration. Fluorescein angiography demonstrated CNV, and treatment was initiated with an anti-vascular endothelial growth factor (anti-VEGF) agent, with significant improvement in vision. Subsequent electroretinogram examination of the patient and her younger sister showed severely reduced rod responses with accentuated fast cone (S-cone only) response, confirming the diagnosis of ESCS as the underlying dystrophy...

BACKGROUND: Anti vascular endothelial growth factor (VEGF) therapy is an established treatment for various retinal diseases. Long-term data on injection frequencies and visual acuity (VA), however, are still rare. METHODS: Five-year analysis of real-life VA developments and injection patterns from 2072 patients (2577 eyes; 33 187 injections) with chronically active disease undergoing pro-re-nata treatment for age-related macular degeneration (AMD), diabetic macular oedema (DME), retinal vein occlusion (RVO) and myopic choroidal neovascularisation (CNV)...

BACKGROUND: Endothelial cells (EC) grown on collagen particles inhibit intimal hyperplasia in animal models when applied perivascularly, and this effect appears to be, at least in part, the result of EC-derived soluble factors that suppress local vascular inflammation. To elucidate the molecular basis of the therapeutic effects of EC grown on collagen particles, the anti-inflammatory activity of conditioned medium from these cells was characterized. METHODS: Human aortic EC (HAEC) and, for chromatin immunoprecipitation assays, human umbilical vein EC (HUVEC) were treated with tumor necrosis factor alpha (TNFα) in the presence of conditioned medium generated by HAEC grown on collagen particles (ECPCM), and the anti-inflammatory effects were evaluated by analysing the expression of the inflammation-related adhesion molecules E-selectin and vascular cell adhesion molecule-1 (VCAM-1)...

Ocular neovascularisation underlies blinding eye diseases such as retinopathy of prematurity, proliferative diabetic retinopathy, and wet age-related macular degeneration. These diseases cause irreversible vision loss, and provide a significant health and economic burden. Biologics targeting vascular endothelial growth factor (VEGF) are the major approach for treatment. However, up to 30% of patients are non-responsive to these drugs and they are associated with ocular and systemic side effects. Therefore, there is a need for small molecule ocular angiogenesis inhibitors to complement existing therapies...

PURPOSE: To describe screening failures in the EVEREST study by examining the imaging characteristics that enabled differentiation of polypoidal choroidal vasculopathy (PCV) from cases that were subsequently diagnosed not to be PCV. METHODS: Post-hoc analysis of 34 patients with PCV reported as screening failures from EVEREST study. Standardised confocal scanning laser indocyanine green angiography (ICGA) images were graded by the Central Reading Centre to confirm PCV diagnosis based on the presence of early focal sub-retinal hyperfluorescence on ICGA and at least one of the following six diagnostic criteria: (1) nodular appearance of polyp(s) on stereoscopic examination, (2) hypofluorescent halo around nodule(s), (3) presence of a branching vascular network, (4) pulsation of polyp(s) on dynamic ICGA, (5) orange sub-retinal nodules on colour fundus photography, or (6) massive sub-macular haemorrhage (≥4 disc areas in size)...

Technetium 99 conjugated with methylene diphosphonate, which is an anti-inflammatory drug, can inhibit macrophage infiltration and downregulate a number of proinflammatory cytokines, such as tumor necrosis factor-α and interleukin-1β. Recently, numerous studies have indicated that it could improve rheumatoid arthritis (RA) activity by upregulating the frequency of peripheral γδ T cells and cluster of differentiation CD4(+)CD25(+)Foxp3(+) Tregs, affecting the serum cytokine environment, inhibiting osteoclast formation and reducing the concentrations of rheumatoid factor-immunoglobulin M (IgM)/IgG/IgA...
