Filter by:The DX-216 trial is a randomized, double-masked, placebo (vehicle)-controlled study evaluating the efficacy and safety of two doses of OCS-01 compared to vehicle in the treatment of inflammation and pain following cataract surgery. The primary objective is to evaluate the efficacy and safety of OCS-01 compared to placebo and the secondary objective is to evaluate the optimal dosing frequency (once a day [QD] or twice a day [BID]).
Steroids and Cross-linking for Ulcer Treatment (SCUT II) is an international, randomized, double-masked, clinical trial. The purpose of this study is to determine differences in 6-month visual acuity between medical antimicrobial treatments alone versus antimicrobial treatment plus collagen cross-linking (CXL), as well as to further evaluate findings from subgroup analyses of SCUT. Patients presenting to the Aravind Eye Care System (India), Kaiser Permanente Northern California (USA), or the University of California, San Francisco (USA) with smear-positive and/or culture-positive typical (i.e. non-Nocardia or Mycobacteria) bacterial corneal ulcers and moderate to severe vision loss, defined as Snellen visual acuity of 20/40 or worse, will be eligible for inclusion. Those who agree to participate will be randomized to one of three treatment groups: Group 1: Standard therapy, topical 0.5% moxifloxacin plus topical placebo plus sham CXL Group 2: Early steroids, topical 0.5% moxifloxacin plus topical difluprednate 0.05% plus sham CXL Group 3: CXL plus early steroids, topical 0.5% moxifloxacin plus topical difluprednate 0.05% plus CXL
The aim of this study is to see if multiplex strip PCR will detect the pathogen that causing eye infection from the corneal scraping samples with higher sensitivity and specificity than the current gold standard.
Design: Prospective observational diagnostic study and methods-comparison. Aims: The overall aim of the project is to better define the pathogenic microorganisms in patients with microbial keratitis (MK) through a better understanding of the corneal and ocular surface microbiome in health and disease. This will be achieved through the following objectives: 1. Using NGS, analyse the corneal microbiome of the affected and unaffected eye of patients with and without MK and compare with simultaneous results from CDC and MTPCR. 2. Determine the microbiological spectrum of the cornea, ocular surface and contiguous structures, in patients with MK, healthy controls, contact lens wearers and eye drop users. Outcome measures: 1. A comparison of isolation rates and identified bacteria obtained from CDC, MTPCR and NGS processing of MK corneal samples will be made. 2. Microorganisms identified in the eyes with MK will be compared to the fellow eye and other control groups and subtractive bioinformatics methodology applied to identify the most likely pathogenic organisms compared to those seen in the healthy corneal and ocular surface microbiome. 3. Comparisons of the relative abundance of microorganisms obtained from MK corneal samples over the participant's follow-up visits will be used to evaluate longitudinal changes in the corneal and ocular surface microbiome during treatment and resolution of MK. 4. A direct comparison between the relative abundance of microorganisms isolated from participants cornea, conjunctiva, eyelids and nose (contiguous structures) will be made to identify any possible endogenous sources of infection for MK. Population Eligibility: - All patients aged 18 years and over presenting with unilateral clinically suspected MK to St. Paul's Eye Unit, The Royal Liverpool University Hospital. - Patients with keratoconus undergoing cross-linking, subjects with no history of MK, subjects with no history of MK who are contact lens wearers and subjects with no history of MK but who are on eye drop treatment for glaucoma. Duration: Three years.
The purpose of this study is to determine if there are microbiologic alterations of the ocular surface after hot tub exposure. The study will evaluate the number of microbes before and after hot tub use in order to find out whether hot tub exposure has any change on the organisms present on the ocular surface. Participants will be randomized to dunk or not to dunk their head during their time in the hot tub.
To determine whether the Peschke PXL-330 system is safe and effective in the treatment of corneal thinning conditions.
This study is a prospective, randomized, open-label, two arms, clinical study aim to evaluate the efficacy and safety of treatment with Hyper-CL™ lens + Antibiotics compared with treatment with Antibiotics only, in subjects with Bacterial keratitis. The design of the Hyper-CL™ lens increases contact time of the antibiotics on the cornea enabling increased bioavailability of the active drug.
Microbial keratitis is an infection of the cornea that is associated with risk of permanent visual impairment. It can be caused by bacteria, virus, fungus, protozoa and parasites. The common risk factors for infectious keratitis include ocular trauma, contact lens wear, recent ocular surgery, preexisting ocular surface disease, dry eyes, lid deformity, corneal sensation impairment, chronic use of topical steroids and systemic immunosuppression .
Cross-over comparison of lipid layer thickness and dry eye symptoms with two artificial tear formulations.
The DRy eye Outcome and Prescription Study (DROPS) is a large observational multicentre study exploring the 'real world' effectiveness of artificial tears in dry eye disease and determinants of efficacy. The aim is to include at least 635 symptomatic dry eye patients who are prescribed artificial tears. All trainees and fellows in London are invited to become collaborators: collaborators are asked to consent patients, assess signs at baseline, and give patients questionnaires at baseline and 4 weeks (for home completion). In tandem, we are conducting a qualitative review of ophthalmologists' prescribing behaviours for dry eye disease.
