BACKGROUND/AIM: Immune cells, e.g. microglial cells of the retina, appear to be involved in pathological processes in neovascular age-related macular degeneration. Therefore, the purpose of this study was to immunohistochemically check the expression of various factors and cytokines by CD11b-positive (CD11b+) immune cells in an animal model of choroidal neovascularisation (CNV). METHODS: We used the animal model of laser-induced CNV in mice. Eyes were isolated at 1, 4, 7, and 14 days after laser treatment...

BACKGROUND: Choroidal neovascularisation (CNV) is a common complication of pathological myopia. Once developed, most eyes with myopic CNV (mCNV) experience a progression to macular atrophy, which leads to irreversible vision loss. Anti-vascular endothelial growth factor (anti-VEGF) therapy is used to treat diseases characterised by neovascularisation and is increasingly used to treat mCNV. OBJECTIVES: To assess the effects of anti-vascular endothelial growth factor (anti-VEGF) therapy for choroidal neovascularisation (CNV), compared with other treatments, sham treatment or no treatment, in people with pathological myopia...

PURPOSE: To compare the findings of optical coherence tomography angiography (OCTA) with indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV) that was divided into two types: polypoidal choroidal neovascularisation (CNV) and typical PCV (type 2 PCV). METHODS: We studied a retrospective case series of 32 patients with treatment-naïve PCV (24 men, eight women; mean age 65.4 years). PCV was categorised into polypoidal CNV (type 1 PCV) and type 2 PCV based on ICGA findings...

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...

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...

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...
