Filter by:The objective of this study is to compare the safety and efficacy of BRM424 OS compared to vehicle in patients with neurotrophic keratitis.
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.
Microbial keratitis is a severe and often blindness-inducing pathology which represents today the first reason for long-term hospitalization (more than 5 days) in ophthalmology. Its diagnosis is clinical and leads to an immediate hospitalization in the presence of serious criteria (Mackie classification). The entire process of microbiological diagnosis requires several days before etiological confirmation and therefore delays the initiation of targeted therapy. Recently, new PCR systems allowing the detection of 18 to 27 pathogens in 75 minutes have been developed. Their use could thus be transposed to ophthalmology by adapting the microbiological diagnostic technique to samples currently taken by swabbing the cornea. The investigators will compare their diagnosis performance versus conventional methods on patients who suffered for a microbial keratitis with severity criteria.
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.
