Quantitative corneal anatomy: evaluation of the effect of diabetes duration on the endothelial cell density and corneal thickness.

2014

Purpose To evaluate the differences in endothelial cell density (ECD) and central corneal thickness (CCT) between type II diabetic patients and age-matched healthy controls, and determine the impact of time from diagnosis. Methods This is a comparative study of 77 eyes of type II diabetic patients (33 males, 44 females) and 80 eyes of healthy subjects (42 males, and 38 females) whose ages ranged from 38 to 56 years. CCT, ECD, HbA1c levels, and Goldmann tonometry were measured. Results The CCT was significantly higher and the ECD significantly lower in long-term diabetic patients (10 years + since diagnosis) when compared with short-term diabetic patients (<1 year since diagnosis) and contro…

Tonographic Effect of Ocular Response Analyzer in Comparison to Goldmann Applanation Tonometry.

2016

AIMS The tonographic effect is a phenomenon of intraocular pressure (IOP) reduction following repeated tonometry. This study examines whether the tonographic effect occurs following IOP measurement performed with Ocular Response Analyzer (ORA). METHODS Both eyes of 31 glaucoma patients and 35 healthy controls underwent nine IOP-measurements performed with GAT and ORA. The number of GAT and ORA measurements performed on each eye differed depending on the randomly allocated investigation scheme. Central corneal thickness (CCT), anterior chamber volume (ACV) and anterior chamber depth (ACD) were assessed with Pentacam before and after the repeated GAT/ORA measurements. RESULTS There was no sta…

Safety and performance of a suprachoroidal sensor for telemetric measurement of intraocular pressure in the EYEMATE-SC trial

2023

AimTo investigate the safety and performance of a telemetric suprachoroidal intraocular pressure (IOP) sensor (EYEMATE-SC) and the accuracy of its IOP measurements in open angle glaucoma (OAG) patients undergoing simultaneous non-penetrating glaucoma surgery (NPGS).MethodsProspective, multicentre, open-label, single-arm, interventional clinical trial. Twenty-four eyes of 24 patients with OAG regularly scheduled for NPGS (canaloplasty or deep sclerectomy) were simultaneously implanted with an EYEMATE-SC sensor. Six-month follow-up on the sensor’s safety and performance as well as on the level of agreement between the EYEMATE-SC measurements and IOP measurements with Goldmann applanation tono…

Conoscenza e percezione: epistemologie cognitiviste e naturalizzazione del relativismo

2010

Uso del tonometro e rischio infettivo ; valutazione dell'efficacia di differenziali tipi di disinfettanti.

2006

Obiettivo: valutare e confrontare l’efficacia dei più comuni tipi di disinfettanti per la disinfezione dei coni tonometrici e trarre alcune indicazioni sulla applicabilità alla realtà clinico-diagnostica in campo oftalmologico. Materiali e metodi: coni tonometrici monouso sterili, previamente contaminati con ceppi standard di Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa e Candida albicans sono stati testati, dopo semplice detersione o disinfezione con acqua ossigenata al 3%, benzalconio cloruro allo 0.5%, Minuten wipes (Alpro® ), Pantasept® allo 0.5% secondo le linee guida del CDC di Atlanta. Risultati: la semplice detersione è stata inefficace contro tutte le specie tes…

Dating of Archaeological Gold by Means of Solid State Electrochemistry

2018

[EN] In archaeology and history of art, age determination is a fundamental analytical problem. While several techniques for age determination of various materials, like radiocarbon dating, are established, these methods cannot be applied for metals, for which new techniques have to be developed. For the first time a dating method for archaeological gold objects is described which is based on a corrosion clock and electrochemical measurements, using the voltammetry of immobilized particles. Samples are prepared by one touch' with a graphite pencil, only transferring a few nanograms of the archaeological gold. The method has been calibrated with the help of a series of well-documented gold sp…
