Filter by:Corneal infection or infectious keratitis (IK) is the most common cause of corneal blindness worldwide, particu-larly in the developing countries1. The incidence was estimated at 2.5-799 per 100,000 population/year. It is a painful and potentially blinding ocular emergency that often requires hospital admission for intensive medical and/or surgical treatment. Depending on the geographical and temporal variations and population-based risk factors (e.g. agricultural practice, trauma, use of contact lens and others), bacteria and fungi have been shown to be the main causative microorganisms for IK, followed by viruses, parasites and polymicrobial infection. Amniotic membrane (AM) is the innermost layer of the placenta, which consists of a single layer of meta-bolically active epithelium, a thick basement membrane, and an avascular stromal matrix (15). It has been shown to exhibit a wide array of biological properties, including wound healing, anti-inflammatory, antimicrobial, and anti-angiogenic properties, amongst others. To date, a number of studies have evaluated the benefit of AMT for treating active IK, though the majority of them were of small case series or case reports. In clinical practice, AMT is usually reserved as a second-line therapy in IK, mainly to promote cornea healing in non-healing ulcer after the sterilization phase.
This study will be used to support assessment of AIR OPTIX® NIGHT & DAY® AQUA (AONDA) Soft Contact Lenses' safety and performance in accordance with updated European Union Medical Device Regulation (EU MDR) requirements.
This study is an observational prospective cohort study which aims to generate an antibiogram and to assess the clinical responses and outcomes of microbial keratitis patients, treated with empiric topical antimicrobial therapies, with the main objective being to recommend the most effective empiric therapy. Microbial keratitis patients are attending the Cornea Outpatient Clinic at Alexandria Main University Hospital, Alexandria, Egypt.
Detecting the cause of keratitis fast is the premise of providing targeted therapy for reducing vision loss and preventing severe complications. Due to overlapping inflammatory features, even expert cornea specialists have relatively poor performance in the identification of causative pathogen of infectious keraitis. In this project, the investigators aim to develop an automated and accurate deep learning system to discriminate among bacterial, fungal, viral, amebic and noninfectious keratitis based on slit-lamp images and evaluated this system using the datasets obtained from mutiple independent clinical centers across China.
The aim of the study was to identify the incidence of infective keratitis presenting to the ophthalmology emergency department at Cairo University hospital, the risk factors and the bacterial/fungal spectrum causing the ulcers and to determine the best possible empirical therapy followed by specific therapy after obtaining culture results.
The purpose of this open, non-comparative, multicenter trial is to assess the impact of eye drops made of Wharton's jelly extract in the treatment of chronic keratitis that failed available therapies.
To evaluate the role of anterior segment optical coherence tomography in follow up of infectious keratitis and assessment of response to treatment.
The purpose of the study is to determine the microbiological aetiology, epidemiological factors, and clinical profile and treatment outcomes of infective keratitis in Ophthalmology department, Minia University. Egypt
Purpose: To evaluate the clinical outcome of patients with refractory Neurotrophic Keratopathy (NK) in stages 2 and 3 treated with topical insulin. Methods: A retrospective, observational analysis of eyes with NK in stages 2 and 3 refractory to standard medical and/or surgical treatment which were treated with topical insulin. Topical insulin (1 unit per mL) was applied 4 times a day; treatment was continued until persistent epithelial defect (PED) or ulcer resolved and then tapered accordingly. The primary outcome of the study was the complete resolution of the PED or ulcer. Best-corrected visual acuity (BCVA), days until complete resolution as well as anterior segment photographs were obtained.
The purpose of this study is to evaluate the safety, tolerability and efficacy of a single escalating doses of BD111 CRISPR/Cas9 mRNA Instantaneous Gene Editing Therapy administered via corneal injection in participants with refractory herpetic viral keratitis.
