Purpose. To report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case...

PURPOSE OF REVIEW: To provide an historical review of the Early Treatment Diabetic Retinopathy Study (ETDRS) in the management of diabetic macular edema (DME), and to discuss its relevance to the management of DME. RECENT FINDINGS: The ETDRS reported that argon laser treatment is beneficial in the management of 'clinically significant' DME. The study provided guidelines for the treatment with focal and/or grid laser based on fluorescein angiographic patterns. In today's world, with the advent of optical coherence tomography, 'clinically significant' DME is now classified into center-involved DME (CI DME) and noncenter-involved DME (non-CI DME)...

INTRODUCTION: Neovascular age-related macular degeneration (nAMD) is the leading cause of vision loss among persons aged 65 years and older. Anti-vascular endothelial growth factor (anti-VEGF) treatment is the recommended standard of care. The current study compares the effectiveness of ranibizumab in routine clinical practice in two countries that generally apply two different treatment regimens, treat-and-extend (T&E) in Australia or pro re nata (PRN) in the UK. METHODS: This retrospective, comparative, non-randomised cohort study is based on patients' data from electronic medical record (EMR) databases in Australia and the UK...

Serine/arginine-protein kinase 1 (SRPK1) regulates alternative splicing of VEGF-A to pro-angiogenic isoforms and SRPK1 inhibition can restore the balance of pro/anti-angiogenic isoforms to normal physiological levels. The lack of potency and selectivity of available compounds has limited development of SRPK1 inhibitors, with the control of alternative splicing by splicing factor-specific kinases yet to be translated. We present here compounds that occupy a binding pocket created by the unique helical insert of SRPK1, and trigger a backbone flip in the hinge region, that results in potent (<10 nM) and selective inhibition of SRPK1 kinase activity...

Purpose: The role of β-adrenergic receptor (AR) signaling in neovascular ocular diseases has recently emerged. We have previously reported that intraperitoneal propranolol inhibits choroidal neovascularization (CNV) in vivo and β2-AR blockade reduces vascular endothelial growth factor (VEGF) expression in mouse retinal pigment epithelium and choroidal endothelial cells in culture. Here we tested the hypothesis that the β2-AR regulates CNV through modulation of VEGF and inflammatory cytokine expression...
