Filter by:Proton beam therapy is a safe irradiation modality for choroidal melanoma. But often after irradiation the exudation increases resulting in an exudative retinal detachment requiring vitreoretinal surgery. It is known that intravitreally injected triamcinolone and TTT is capable to decrease the exudation. If there is any advantage in a combined treatment this study will investigate.
The purpose of this study is to evaluate whether postoperative postures influence persistent sub-foveal fluid after scleral buckle surgery
Acute retinal necrosis (ARN) is a rare infectious retinitis which can potentially lead to devastating visual outcomes. ARN is diagnosed on the basis of the clinical appearance and disease course according to the diagnostic criteria proposed by the American Uveitis Society: (1) one or more foci of retinal necrosis with discrete borders in the peripheral retina; (2) rapid progression in the absence of antiviral therapy; (3) circumferential spread; (4) occlusive vasculopathy with arteriolar involvement; and (5) a prominent inflammatory reaction in the vitreous and anterior chambers. Herpesvirus infection, especially varicella-zoster virus (VZV) and herpes simplex virus (HSV), was presumed to be the pathogenic agent in the pathogenesis of ARN. Medical treatment with systemic antiviral agent had been the base of the therapy of ARN for decades and such treatment usually result in regression of retinitis. However, the visual outcome of ARN remains poor. The major causes of poor visual prognosis in ARN are retinal detachment and optic nerve or macular involvement by ischemic vasculopathy. Less frequent causes include macular hole formation, macular pucker, or hypotony. Rhegmatogenous retinal detachment may occur in 75 % of the untreated eyes. It may occur weeks to months after the onset of inflammation due to delayed formation of retinal breaks, which result from the combination of necrotic retina and vitreoretinal traction. Therefore, application of argon laser retinopexy prophylactically posterior to necrotic retina or prophylactic vitrectomy to reduce inflammatory factors and the vitreoretinal traction had been used to protect the healthy area from detachment. However, the results were varied and there is no consensus on the efficacy and indications of those prophylactic procedures. We had applied the prophylactic procedure in our treatment for ARN. We aim to access the efficacy of the treatment strategy of ARN and the correlated factors to the outcomes.
Comparison between intravitreous glucose rate and macular thinning measured by Ocular Coherence Tomography (OCT) at 3 months post vitrectomy for retinal detachment or epimacular membrane. Hypothesis : Association between post-operative macular thickness and intravitreous glucose rate
Retinal re-detachment in silicone oil filled eye, especially in the traumatic eye, is a complex retinal detachment with poor prognosis. In this study, the investigators try to apply a modified surgery as Multi-electrocoagulation retinectomy to reattach the retina. Here the investigators aimed to explore the safety and efficacy of this new surgical approach
The investigators hypothesize that bevacizumab instilled into the vitreous after primary retinal detachment surgery will reduce the formation of proliferative vitreoretinopathy and subsequent retinal re-detachment.
There are multiple ways to treat retinal detachment, the aim of this study is to compare the amount of corneal endothelial cell loss after pneumatic retinopexy in comparison to vitrectomy.
We investigated the hemostatic differences according to the main anesthetic agents by analyzing rotational thromboelastometry (ROTEM) under the hypothesis that propofol-based anesthesia would impair postoperative coagulability more than the sevoflurane-based anesthesia.
Primary Objectives: To assess the efficacy of intravitreal administered Eylea in preventing visual loss in subjects with a retinal pigment epithelial detachment (PED) subtype of neovascular age-related macular degeneration (AMD) measured by mean change in BCVA at Month 12 compared to Baseline. Secondary Objectives: 1. To assess the safety and tolerability of repeated intravitreal administration of Eylea in subjects with the PED subtype of neovascular AMD for a period of 1 year 2. To assess the effect of repeated intravitreal administration of Eylea on Central Subfield Thickness (CSFT), Central Subfield Volume (CSFV), and PED height and volume. 3. To assess the effect of repeated intravitreal administration of Eylea on vision related quality of life in subjects with PED study type of neovascular AMD assessed using the NEI/VFQ-25 questionnaire
The fibrin sealants are prepared from fibrinogen, thrombin, and sometimes factor XIII that have been purified from human plasma. Tissucol Duo Quick (Baxter, Vienna, Austria) is a kind of fibrin sealants with popular use. It is a 2-component tissue adhesive that resembles natural fibrin formation. This glue has 2 components: fibrinogen (mixed with factor XIII and aprotinin) and thrombin-CaCl2 solution. When equal amounts of the 2 components are mixed, the monomers aggregate by cross-linking, resulting in a fibrin clot. It forms a elastic, whitish substance and provides strong adhesion to the tissue. Therefore, it is a good agent to seal small wounds or to replace the use of suture.
