Disease staging involves the assessment of disease severity or progression and is used for treatment selection. In diabetic retinopathy, using a wide area more desirable than that limited area. We investigated if deep learning artificial intelligence (AI) could be to grade retinopathy determine prognosis.The retrospective study analyzed 9,939 posterior pole photographs 2,740 patients with diabetes. Nonmydriatic 45° field color fundus were taken four fields in each eye annually at Jichi...

Background. The expression of Fas ligand (FasL) in the eye has been proposed to be an important component ocular immune privilege. Since unusually favorable outcome corneal transplantation is thought result from privilege eye, examination function FasL on allografts would a test that hypothesis. Methods. To investigate role Fas-FasL interaction allografts, orthotopic was performed using C57BL/6(B6, FasL+) and B6-gld (FasL-) mice as cornea donors BALB/c recipients. rejection rate grafts...

The aim of this study was to investigate the safety and efficacy a single injection intravitreal faricimab (IVF) in patients with neovascular age-related macular degeneration (nAMD) who had prior treatment history.A retrospective analysis conducted on consecutive cohort 80 eyes 75 nAMD history an anti-vascular endothelial growth factor. Best-corrected visual acuity (BCVA), central subfield thickness (CST), choroidal (CCT) were compared before initial IVF after interval matching previous...

Purpose: To identify factors associated with intraocular inflammation (IOI) in patients neovascular age-related macular degeneration (nAMD) treated brolucizumab. Methods: In this prospective observational study, we collected aqueous humor samples from 96 eyes of receiving treatment brolucizumab; IOI subsequently developed 19 patients. cytokines upregulated subsequent development IOI, compared the cytokine levels between and non-IOI groups. We also plasma 20 who age- sex-matched controls to...

Although intraocular pressure (IOP) is the most definitive cause of glaucoma, a subtype open angle glaucoma (OAG) termed normal tension (NTG), which occurs in spite IOP, accounts for large part cases, especially Japan. To find common genetic variants contributing to NTG Japanese patients, we conducted genome-wide association study (GWAS). We performed first screening 531,009 autosomal SNPs with discovery cohort 286 cases and 557 controls, then second top 30 suggestive loci an independent 183...

The distribution of uveitis varies with genetic, ethnic, geographic, environmental, and lifestyle factors. Epidemiological information about the patterns is useful when an ophthalmologist considers diagnosis uveitis. Therefore, it important to identify causes over years in different regions. purposes this study were characterize patients who first arrived at University Tokyo Hospital 2013–2015, analyze changes from 2004 2012 2013–2015. We retrospectively identified 750 newly visited Uveitis...

To determine changes in multiple cytokine concentrations the anterior chamber during induction phase of ranibizumab treatment patients with neovascular age-related macular degeneration (AMD).This prospective study included 48 treatment-naïve AMD eyes who received three consecutive monthly injections at Japan Community Health Care Organization Tokyo Shinjuku Medical Center between November 2010 and August 2012. We collected ~0.2 mL aqueous humour before first third (2 months later)...

Purpose: Commercially available enzyme-linked immunosorbent assay (ELISA) kits are often used to monitor vascular endothelial growth factor (VEGF) levels in exudative age-related macular degeneration. To test their accuracy, this study performed measurements using the ELISA presence of anti-VEGF drugs. Methods: The concentrations bevacizumab, pegaptanib, or ranibizumab at 28 days and aflibercept 56 after an injection were estimated based on previous pharmacokinetic studies. Vascular measured...

Abstract Treatment of uveitis is complicated because its multiple aetiologies and elevation various inflammatory mediators. To determine the mediators that are elevated in vitreous humor according to aetiology uveitis, we examined concentrations 21 cytokines, 7 chemokines, 5 colony-stimulating/growth factors samples from 57 eyes with associated intraocular lymphoma (IOL, n = 13), sarcoidosis (n 15), acute retinal necrosis (ARN, or bacterial endophthalmitis (BE, 16). Samples idiopathic...

Abstract This single-center retrospective cohort study analyzed the 1-year real-world treatment outcomes of 63 consecutive eyes (of 60 patients) with neovascular age-related macular degeneration (nAMD) that were switched from intravitreal brolucizumab (IVBr) to faricimab (IVF) and managed on a treat-and-extend regimen discontinuation criteria. After switch, patients opted continue IVF, switch back IVBr, or receive photodynamic therapy (PDT). Thirty-eight continued 16 2 received PDT, 4 paused...
