Choroidal neovascularisation (CNV) is a common vision-threatening complication of myopia and pathological myopia. Despite significant advances in understanding the epidemiology, pathogenesis and natural history of myopic CNV, there is no standard definition of myopic CNV and its relationship to axial length and other myopic degenerative changes. Several treatments are available to ophthalmologi...

Choroidal neovascularization (CNV) is the defining characteristic feature of the wet subtype of age-related macular degeneration (AMD) and may result in irreversible blindness. Based on anti-vascular endothelial growth factor (anti-VEGF), the current therapeutic approaches to CNV are fraught with difficulties, and mammalian target of rapamycin (mTOR) has recently been proposed as a possible the...

Aim: To evaluate the long-term outcome of photodynamic therapy (PDT) for idiopathic choroidal neovascularization (CNV). Methods: Retrospective review of 30 eyes (27 patients) treated with PDT for naïve idiopathic CNV, and completed at least five-year follow-up. Best-corrected visual acuity (BCVA, logMAR; logarithm of minimum angle resolution) at baseline and each follow-up visit were investigat...

Anti-glomerular basement membrane antibody disease (anti-GBM disease) is a rare disorder characteristic of universally poor outcome. Fcgamma receptors (FcgammaRs) play important roles in anti-GBM disease based on evidence from animal models. Copy number variation (CNV) influences disease susceptibility. The FcgammaRs genes show CNV, and CNV of the FCGR3B gene is associated with glomerulonephrit...

PURPOSE We investigated the effects of semaphorin 3E (Sema3E)/PlexinD1 signaling in the development of choroidal neovascularization (CNV) and explored the therapeutic potential of the pathway. METHODS We used a laser-induced CNV model in the mouse. The expression of Sema3E and PlexinD1 was evaluated with immunohistochemistry, real-time RT-PCR, and Western blotting. After the intravitreal inje...

MicroRNAs (miRNAs) are a widespread class of regulatory noncoding RNAs with key roles in physiology and development, conferring robustness to noise in regulatory networks. Consistent with this buffering function, it was recently suggested that human miRNAs coevolve with genes in copy number regions (copy number variation [CNV] genes) to reduce dosage imbalance. Here, I compare miRNA regulation ...

Age-related macular degeneration (AMD) is the most common cause of legal blindness among the elderly in developed countries. The prevalence of advanced forms of AMD is increasing; it is expected to rise by 50% by the year 2020 in the United States. Early identification of AMD susceptibility and implementation of preventive measures are important management strategies. Antibodies against vascula...

Purpose Age-related macular degeneration (AMD) is the leading cause of central visual loss among patients over the age of 55 years worldwide. Neovascular-type AMD (nAMD) accounts for approximately 10% of patients with AMD and is characterized by choroidal neovascularization (CNV). The proliferation of choroidal endothelial cells (CECs) is one important step in the formation of new vessels. Tran...

Purpose To compare the efficacy of microneedle-delivered suprachoroidal (SC) pazopanib to intravitreal (Ivit) delivery of pazopanib, bevacizumab, or a fusion protein hI-con1 versus vehicle controls on choroidal neovascularization (CNV) growth in a pig model. Methods Forty-one pigs were injected on the day of CNV induction (hI-con1 on postinduction day 14) with either 2.5 mg Ivit bevacizumab (...

Choroidal neovascularization (CNV) is the common pathological basis of irreversible visual impairment encountered in a variety of chorioretinal diseases; the pathogenesis of its development is complicated and still imperfectly understood. Recent studies indicated that delta-like ligand 4 (Dll4), one of the Notch family ligands might participate in the HIF-1α-VEGF pathway to regulate CNV angioge...
