AIM We conducted this study to evaluate and compare corneal endothelial cell loss between phacoemulsification with continuous anterior chamber infusion using anterior chamber maintainer (ACM) and phacoemulsification using ophthalmic viscosurgical device (OVD). MATERIALS AND METHODS This was a prospective, randomized controlled trial. Fifty eyes of 47 patients of senile cataract undergoing pha...
PURPOSE To report 1-year results of laser in situ keratomileusis (LASIK) in 7 eyes with corneal endothelial guttata and a family history of Fuchs' endothelial dystrophy. SETTING John Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. METHODS A retrospective chart review was performed of 4 patients (7 eyes) who had trace to 1+endothelial guttata and a family history of Fuchs dy...
Background: Angiogenesis disorders are known mechanisms of diabetes. With the aim of reducing angiogenesis disorders, resistance training and its combination with endothelial progenitor cell injection are new strategies. Therefore, the present study was performed to determine the effect of resistance training with endothelial progenitor cell injection on the expression of angiogenic factors in ...
IMPORTANCE Surgeons starting to perform Descemet membrane endothelial keratoplasty (DMEK) should be informed about the learning curve and experience of others. OBJECTIVE To document the clinical outcome of standardized "no-touch" DMEK and its complications during the learning curves of experienced surgeons. DESIGN, SETTING, AND PARTICIPANTS Retrospective multicenter study. A total of 431 ey...
background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...
purpose: to compare corneal endothelial cell features after cataract surgery performed using fixed torsional or conventional (pulse) ultrasound mode. methods: in this randomized comparative study, 60 eyes were randomly and equally divided into two groups of torsional or longitudinal mode phacoemulsification. all surgeries were performed by an experienced surgeon, and the outcomes were evaluated...
to evaluate corneal endothelial cell changes after intravitreal and subconjunctival injection of avastin (bevacizumab) based on specular microscopic findings. this prospective interventional study was performed on 82 eyes of 82 patients. forty-two cases with ptrygia received a subconjunctival injection of bevacizumab (2.5mg/0.2ml) and 40 diabetic subjects with retinal neovascularization or mac...
background: angiogenesis, the formation of new blood vessels from preexisting ones, is one of the most important physiological and pathological processes occur in the body. in the pathological conditions such as tumor growth, psoriasis, corneal neovascularization and rheumatoid arthritis, angiogenesis is crucially required for the devolopment of the disease. zataria multiflora as a member of la...
PURPOSE When comparing follow-up endothelial cell (EC) density measurements it is only possible to demonstrate cell loss in large cohorts or in pronounced cases due to the standard deviation of measurements. However, especially in clinical studies or refractive surgery patients, EC stability is an important factor. Thus we developed a computer program to achieve cell-by-cell alignment of conven...
Objective(s): To investigate the effect of miR-103 on the angiogenesis of ischemic stroke rats via targeting vascular endothelial growth factor (VEGF) at the molecular level. Materials and Methods: Rat models had received the middle cerebral artery occlusion (MCAO) or sham operation before grouping, and cell models of oxygen-glucose deprivation (OGD) were performed. FITC-dextran, matrigel, and ...
