To evaluate the accuracy of intraocular pressure (IOP) measurements obtained with newly available iCare HOME (RTHOME) rebound tonometer compared ONE (RTONE) and Goldmann applanation tonometry (GAT), possible correlation central corneal thickness (CCT).IOP were from 154 patients by an ophthalmologist (doc) using each above-mentioned tonometers. In addition, (pat) measured their own IOP RTHOME RTONE. The means SD results different tonometers compared. Agreement between was calculated...

PURPOSE: To determine long-term changes in corneal transparency after riboflavin-ultraviolet A-induced collagen cross-linking (CXL). METHODS: Charts and anterior segment data of patients CXL for progressive keratoconus were retrospectively reviewed. Patients examined using the Scheimpflug-based Pentacam densitometry module (Oculus Optikgeräte, Wetzlar, Germany) before at five postoperative follow-up visits: 1 to 3, 3 6, 6 12, 12 24, 24 36 months. RESULTS: Forty-two eyes 28 (mean age: 27.9 ±...

Abstract Coronin‐3 (coronin‐1C), a homotrimeric F‐actin binding protein, has been shown to be important for cell migration and brain morphogenesis. Here, we present the first time detailed analysis of expression pattern coronin‐3 in human tumours demonstrate that correlates with malignant phenotype diffuse gliomas. In general, varies different tumour entities. However, gliomas, number expressing cells degree malignancy. High‐grade such as anaplastic astrocytomas, oligodendrogliomas,...

<h3>Background</h3> Aqueous flare as determined by laser photometry in the anterior chamber is a strong preoperative predictor for proliferative vitreoretinopathy (PVR) patients with primary retinal detachment (RD). We analysed various cytokines aqueous humour samples relation to and postoperative PVR incidence RD. <h3>Methods</h3> Preoperatively, of RD was measured quantitatively metre were collected interferon γ, tumour necrosis factor α, monocyte chemoattractant protein (MCP)-1,...

To compare the practicability of using an Icare rebound tonometer (RT) versus a Goldmann applanation (GAT) or Pascal dynamic contour (DCT) for measuring intraocular pressure (IOP) in patients with corneal abnormalities and, furthermore, to study influence central thickness, diameter, radius, and axial length.One hundred seventy-one pathologic eyes 26 nonpathologic control 99 were included. Pathologic corneas divided into subgroups: previous keratoplasty, keratoconus, scars, dystrophies,...
