Among patients with angle-closure glaucoma, it is common to have a short-axial eye, which also makes difficult select an appropriate intraocular lens. Previous studies focused on the ocular biometry of long-axial whereas only few reports eye. This study aimed clarify characteristics eye among elderly Japanese. retrospective cross-sectional included 142 who consulted at our hospital. The axial length (AL), central corneal thickness (CCT), average anterior radius curvature (CR), white-to-white...
Keratoconus (KC) is a progressive corneal disorder resulting in severe visual impairment. We aimed to determine the prevalence and tomographic characteristics of KC keratoconus suspect (KCS) population-based study, construct discrimination models with or without tomography. A total 1,544 eyes (822 participants aged ≥35 years) were evaluated using data from Yamagata Study (2015–2017). Systemic ophthalmological examinations including tomography swept-source anterior segment optical coherence...
Purpose: To examine the association between glucose metabolism and central corneal thickness (CCT) in Japanese adults.Methods: A sub-sample of 322 adults participating Funagata Study was included this analysis. CCT measured using a specular microscope. Glucose examined 75-g oral tolerance test. Mean differences (μm) 95% confidence intervals were estimated with univariate, age–sex-adjusted multivariate models multiple linear regression.Results: The mean (± standard deviation) age study sample...
Background/Aim To determine the preoperative ocular factors and surgical methods that led to best-corrected visual acuity (BCVA) after pars plana vitrectomy (PPV) or scleral buckling (SB) for rhegmatogenous retinal detachment (RRD). Methods This was a prospective, nationwide, multicentre, observational study. Data from Japanese Retina Vitreous Society registry 2016 2017 were used association between clinical factors, procedures postoperative BCVA at 6 months. individuals >40 years of age...
Proliferative diabetic retinopathy (PDR) is the most severe case of that can cause visual impairment. This study aimed to reveal factors correlated with better postoperative acuity after a long follow-up in patients who underwent vitrectomy for PDR. We retrospectively analyzed data set including systemic findings, ocular and surgical from registered could be completely followed up 2 or 4 years vitrectomy. ultimately enrolled 128 eyes 100 PDR between January 2008 September 2012 were >2...
Purpose: Ocular parameters are not only useful for diagnosing diseases but also guiding treatment approaches. A lot of previous studies have reported ocular and its relations before cataract surgery. However, despite ethnic differences in biometry, few reports dealt with Japanese. Hence, this retrospective cross-sectional study aimed to measure preoperative patients examines the correlations between each parameter Japanese elderly people. Patients Methods: The 210 subjects had their axial...
Despite numerous investigations into ocular or corneal astigmatism, the dynamic nature of astigmatism remains poorly understood. To reveal potential associations between age and 264 Japanese participants who underwent systemic ophthalmological examinations in Funagata Town (Yamagata Prefecture, Japan) were evaluated over a 10-year period. Astigmatism was with regard to cylinder power, axis, vector analyses. Whereas refractive cylinders showed age-related increases patients their 40s 60s, did...
To compare clinical outcomes between pars plana vitrectomy (PPV), scleral buckling (SB), and PPV+SB for rhegmatogenous retinal detachment in the Japan-RD Registry.This is a nation-wide, multicenter, observational study based on registry data 2016 2017. The failure levels were defined as Level 1 (a of repair), 2 (remaining silicone oil), 3 (multiple surgeries to achieve reattachment). We compared cases treated by SB or PPV subgroup simple using multivariate Cox proportional hazard models.A...
Abstract Rhegmatogenous retinal detachment (RRD) causes a permanent decrease in visual acuity and field. During pars plana vitrectomy (PPV) for RRD, long acting gas have been selected tamponade because stays the eye time. Recently, several studies showed efficacy of air RRD treatment. Few prospective analyzed tamponade. We registered 194 eyes from 190 patients who consented to study PPV with by single surgeon June 2019 November 2022. These were all treated without silicone oil followed >...
This study aimed to investigate the roles played by vitreous-derived cells in pathogenesis of vitreoretinal vascular diseases.The vitreous was removed from porcine eyes and small pieces were cultured which isolated. Polymerase chain reaction ELISA performed determine expression endothelial growth factor (VEGF) interleukin 6 (IL-6) at mRNA protein levels, respectively. The viability human retinal (HRECs) exposed assessed MTT assay.Expression VEGF IL-6 increased exposing (PVDCs)...
Baricitinib is a Janus kinase (JAK) inhibitor used to treat refractory rheumatoid arthritis and blocks the subtypes JAK1 JAK2. A 35-year-old man with seronegative complicated by bilateral severe non-granulomatous panuveitis was resistant steroid treatment, multiple conventional disease-modifying antirheumatic drugs (methotrexate salazosulfapyridine), TNF-α inhibitors (adalimumab infliximab). Therefore, were switched baricitinib decrease activity of systemic arthritis. Along amelioration...
Purpose: To compare air tamponade and sulfur hexafluoride (SF6) gas during vitrectomy for the treatment of rhegmatogenous retinal detachment (RRD). Methods: We reviewed 294 eyes with RRD treated 25-gauge by a single surgeon between June 2011 April 2018 retrospectively. The exclusion criteria proposed selection were more than 2 weeks since onset, giant tears, history complications following cataract surgery, high myopia, proliferative vitreoretinopathy classified as grade C or higher....

To investigate how aging affects corneal geometry in Japanese adults, and the association between astigmatism.We included 421 participants who had undergone systemic ophthalmological examinations 2015 Funagata town, Yamagata, Japan. Corneal topographic data were obtained using anterior-segment optical coherence tomography (CASIA SS-1000). Astigmatism was evaluated power vector analyses where J0 represents of orthogonal astigmatism. Positive values indicate with-the-rule astigmatism, while...
To investigate how age and other factors affect astigmatism in Japanese adults over a period of 5 years.We included 512 participants who had undergone systemic ophthalmological examinations both 2005-2007 2010-2012 Funagata town, Yamagata, Japan. Astigmatism was evaluated using power vector analyses, where J0 represents the orthogonal astigmatism. Positive values indicate with-the-rule astigmatism, whereas negative against-the-rule (ATR).In this cross-sectional investigation, represented...
This study aimed to evaluate the 3-year long-term outcomes of primary Baerveldt glaucoma implant (BGI) surgery for neovascular (NVG). We retrospectively evaluated 27 consecutive patients with NVG between November 2013 and 2017. All were treated panretinal photocoagulation pars plana vitrectomy before BGI without anti-vascular endothelial growth factor treatment. The surgical success was defined as an IOP <22 mmHg <5 or antiglaucoma medication. assessed on basis intraocular pressure...
Abstract The purpose of this study was to investigate the effects surgeon-related factors on surgical outcome pars plana vitrectomy (PPV) and scleral buckling (SB) surgery eyes with a rhegmatogenous retinal detachment (RRD). This nationwide, multicenter, observational data in Japan-RD Registry. Registered cases that had undergone for RRD by 128 accredited surgeons 26 institutions were studied. significantly affected success visual outcomes simple treated PPV or SB at 6 months postoperatively...
