This study aimed to explore predictors of long-term stabilization of polypoidal choroidal vasculopathy (PCV) lesions and vision in response to injection of intravitreal ranibizumab (IVR). The treated eyes had a baseline best corrected visual acuity (BCVA) of at least 0.6 (logarithm of the minimal angle of resolution (logMAR) 0.22).We treated 45 eyes showing BCVA between 0.6 (logMAR 0.22) and 1.0 (logMAR 0), with IVR for 3 consecutive months. All eyes were confirmed to have subfoveal PCV prior to starting this treatment regimen...

The aim of this study was to evaluate the regional variations of peripapillary choroidal thickness (PCT) in normal-tension glaucoma (NTG) patients with a retinal nerve fiber layer (RNFL) defect localized to a single superior or inferior hemifield. This is a retrospective, cross-sectional study.Ninety-five NTG patients and 53 normal subjects were divided into 3 groups: 34 eyes with a superior RNFL defect (group A), 61 eyes with an inferior RNFL defect (group B), and 53 normal eyes (group C). The average, quadrant, and clock-hour RNFL thickness (RNFLT) and PCT were measured using spectral-domain optical coherence tomography...

BACKGROUND/AIMS: To evaluate the 5-year visual and anatomical outcomes after anti-vascular endothelial growth factor (VEGF) therapy alone or in combination with photodynamic therapy (PDT), followed by pro re nata (PRN) anti-VEGF therapy with or without PDT, for polypoidal choroidal vasculopathy (PCV). METHODS: This retrospective, observational study included 61 consecutive patients with treatment-naïve symptomatic PCV who were followed for 5 years. Twenty eyes (20 patients) initially received PDT and intravitreal injection of ranibizumab (IVR), followed by a PRN regimen of anti-VEGF therapy with or without PDT (combination group), while 41 eyes (41 patients) initially received only IVR every 3 months, followed by a PRN regimen of anti-VEGF monotherapy (IVR group)...

Bevacizumab is an anti-vascular endothelial growth factor drug that can be used to treat choroidal neovascularization (CNV). Bevacizumab-loaded multivesicular liposomes (Bev-MVLs) have been designed and developed to increase the intravitreal retention time of bevacizumab and reduce the number of injection times. In this study, Bev-MVLs with high encapsulation efficiency were prepared by double emulsification technique, and antibody activity was determined. The results revealed that 10% of human serum albumin (HSA) could preserve the activity of bevacizumab...

AIM: To investigate the roles of integrins in choroidal neovascularization (CNV) and their associations with the stromal cell-derived factor-1 (SDF-1)/CXCR4 axis. METHODS: CNV lesions were induced in mice using laser photocoagulation. After CNV induction, all animals were randomly assigned to: control, SDF-1, SDF-1+age-related macular degeneration (AMD) 3100 (CXCR4 inhibitor), and SDF-1+ATN161 (integrin α5β1 inhibitor) groups; their effects on CNV progression were observed using hematoxylin eosin (HE) staining, fundus fluorescein angiography (FFA) grading and optical coherence tomography (OCT), and their effects on CXCR4/integrin α5 expression were evaluated using Western blot and double immunofluorescence staining...

PURPOSE: To evaluate the clinical characteristics of β-PPA in myopic eyes and determine whether the microstructure of β-PPA is associated with parapapillary microvasculature by using optical coherence tomography (OCT) angiography. DESIGN: Cross-sectional study METHODS: This study included 80 subjects with myopia with β-PPA. Spherical equivalent (SE) refractive error, axial length, horizontal tilt angle, and the width of β-PPA were evaluated. The microstructure of β-PPA and subfoveal choroidal thickness were evaluated using enhanced-depth imaging OCT and eyes were classified into 3 groups based on the presence of Bruch's membrane (BM), a PPA+BM only group, a PPA+BM and PPA-BM group, and a PPA-BM only group...
