Background: The exact pathogenesis of idiopathic choroidal neovascularization (ICNV) remains unclear. Cytokine-mediated inflammation has been thought to be involved in the pathophysiology of ICNV. The purpose of this study was to investigate serum cytokine profiles in patients with ICNV and to explore the relationship between serum cytokine levels and ICNV severity.
Methods: This case-control study was conducted in 32 ICNV patients and 30 healthy volunteers. Clinical and demographic information was obtained from the medical data platform and the serum was analysed with a multiplex assay to determine the levels of seven cytokines: interleukin (IL)-2, IL-10, IL-15, IL-17, basic fibroblast growth factor (basic FGF), granulocyte-macrophage colony-stimulating factor (GM-CSF), and vascular endothelial growth factor (VEGF).
Results: Serum levels of IL-2, IL-10, IL-17, basic FGF, and VEGF were elevated in ICNV patients compared to controls. Serum GM-CSF levels were positively related to central retinal thickness, and serum IL-17 levels were positively related to CNV lesion area.
Conclusion: Serum inflammatory cytokines were significantly elevated in ICNV patients compared to controls. This suggests that systemic inflammation may play a critical role in the physiopathology of ICNV.

Epithelial cancers are typically heterogeneous with primary prostate cancer being a typical example of histological and genomic variation. Prior studies of primary prostate cancer tumour genetics revealed extensive inter and intra-patient genomic tumour heterogeneity. Recent advances in machine learning have enabled the inference of ground-truth genomic single-nucleotide and copy number variant status from transcript data.

Purpose: The purpose of this study was to identify biomarkers that predict the response of treatment-naive idiopathic choroidal neovascularization (iCNV) to anti-VEGF treatment.
Methods: Fourteen eyes diagnosed with iCNV underwent a dilated fundus examination, Swept Source Optical Coherence Tomography (SS-OCT) and Optical Coherence Tomography - Angiography (OCT-A), and were given an anti-VEGF injection. The same examinations were repeated at every follow-up visit.
Relationship between Contingent Negative Variation and afterimage duration in migraine patients.

Background: Abnormalities in electrocortical parameters and persistence of afterimage after visual stimulation are known to occur in migraine patients. The results of studies on Contingent Negative Variation (CNV) and afterimage persistence in migraine patients suggest a link between these two phenomena and a connection to the pathomechanism of migraine.
Objectives: To date, no studies have investigated both afterimage duration and CNV parameters in the same subjects.

Electronic address:
Purpose: To evaluate the influence of immunomodulatory therapy (IMT) on visual and treatment outcomes of inflammatory choroidal neovascularization (iCNV) in patients affected by multifocal choroiditis (MFC), and to compare them to patients treated with steroids as needed.
Design: Multicenter retrospective matched cohort study.
Methods: Patients affected by MFC with iCNV were divided into a IMT group and a "steroids as needed" group and matched according to the time between diagnosis and beginning of systemic treatment.
