Filter by:The goal of this observational study is to identify prognostic and/or diagnostic signatures (biomarkers) related to microbial keratitis outcomes. We will compare tear and ocular swab samples from participants currently suffering from microbial keratitis to healthy control participants. The primary study objective is to undertake analysis (proteomics and metabolomics) of microbial keratitis patient (and healthy control) ocular samples collected throughout the patient treatment course to better understand the ocular microenvironment and to identify candidate biomarkers for future targeted screening and validation studies. The secondary study objective is to define the microorganisms in patients with microbial keratitis through a better understanding of the ocular surface micro/mycobiome (the resident bacteria and fungi) in health and disease Participants will have their tears collected via capillary tube during their treatment course, and swabs of their conjunctiva collected at their first and final appointments.
The primary aim of this study is to investigate the efficiency of PACK_ CXL in treatment of infectious keratitis and analyze postoperative outcomes.
The purpose of this study is to assess the efficacy of sural nerve transfer and cadaveric nerve graft to re-establish corneal sensation in patients with neurotrophic keratopathy.
This study is designed to learn more about the impact different types of stimuli, such as heat, cold and vibration, can have on ocular pain response. This is called quantitative sensory testing (QST). Most procedures being performed in this study, except the QST, are standard of care which means they are performed during the participant's routine eye examination.
Objective: To compare the additive effect of topical cyclosporine A 0.05% eye drops to prednisolone eye drops, with topical prednisolone acetate 1% eye drops alone in treatment of herpetic stromal keratitis. Methods: Patients diagnosed with herpetic stromal keratitis are randomly divided into 2 groups; Group A: receive cyclosporine eye drops together with prednisolone eye drops. Group B: receive topical prednisolone with placebo eye drops (tear replacement). The 2 groups receive systemic acyclovir therapeutic dose 400 mg five times daily, which then tapered to twice daily prophylactic dose after one month of treatment. Follow up for patients is scheduled as a weekly visit for a duration of 2 months.
To compare the therapeutic effect of ozone-based eye drops as an adjuvant therapy to that of the conventional topical antimicrobial agents in patients with microbial keratitis . The therapeutic response will be evaluated with clinical examination follow up .
This is an open-label and prospective clinical trial, in which a maximum of 5 eyes of 5 patients will receive a CLP-PEG-MPC synthetic cornea during deep anterior lamellar keratoplasty (DALK) surgery and will be followed up over 24 months.
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.
As conventional corneal scraping with bacterial culturing has several disadvantages such as long duration until diagnosis, invasiveness and lacks alternatives, there is demand for a novel non-invasive, rapid test in keratitis management. First aim of this study will be to evaluate the influence of TNF-alpha on Gram+ and Gram- bacteria causing keratitis. Second aim of this study will be to develop an algorithm, that should help to distinguish between different pathogens causing keratitis.
Evaluate the association between level of decreased corneal sensitivity and diabetic retinopathy severity scale
