Filter by:The purpose of this study is to evaluate the usability of the iTEAR100 generation 2 device in combination with its newly developed iLIDS100 disposable cover.
To compare the efficacy of XDEMVY ophthalmic drop to its vehicle control for the treatment of Demodex blepharitis and its impact on the soft contact lens wearing experience.
This is a multi-center, multidisciplinary, open-label, randomized controlled prospective clinical study.
One hundred blepharitis patients will be recruited. Each patient will treat one eye once daily with 1% PVI for 30 days by scrubbing the eyelid margin with the solution. The fellow eye will serve as the control and be given the standard treatment (commercial eye wipes). Before treatment initiation, various ocular surface variables will be assessed, such as dry eye grading, subjective discomfort scales, ocular surface questionnaire, and other clinical signs. After 30 days, an identical evaluation will be performed.
Dry eye is often reported as the most common complication after a laser refractive surgery. Any refractive procedure can lead an impact on the corneal surface and the tear film. The main cause of this dry eye is the corneal denervation caused by the destruction of the anterior stromal nerves during the ablative procedure. This loss of corneal sensitivity leads to a decrease in the blink reflex, a decrease in the secretion rate of the meibomian glands and finally an evaporated dry eye. There is also a chronic inflammation at the corneal surface that produces an increase of inflammatory cytokines and a dysfunction of the meibomian glands. Yu et al have described incidences of dry eye closed to 60% after the first month of LASIK. Hovanesian et al have observed dry eye symptoms in 50% of patients 6 months after surgery. Donnenfeld et al describe 15% of moderate dry eye in the following 3 months and 5% of severe dry eye in the first 6 months. A small number of patients will present with chronic dry eye symptoms for more than 1 year. Bower et al analyzed its incidence in 0.8% Alterations in the tear film also decrease the quality of the retinal image and produce greater number of high-order due to the irregular. Pulsed light therapy (IPL) applied preoperatively in patients who undergo a laser refractive surgery may prevent the post-surgical dry eye and improve the refractive results. The aim of our study is to evaluate the usefulness of the applied therapy for the prevention of dry eye in patients that undergo a corneal refractive procedure.
Lid cleansing is the standard regime that is recommended for the management of blepharitis in the UK and beyond. Whilst many successful commercial preparations exist, and some with clinical evidence, professional guidelines (UK Royal College of Ophthalmologists, UK College of Optometrists, AAO, etc.) continue to advocate the use of a diluted solution of baby shampoo, despite no clinical evidence of its safety, tolerance or long term effectiveness, and despite a statement form the manufacturers that it should not be used for this purpose. Where licensed, registered products exist it seems bizarre that we have this situation, but a Cochrane review from 2012 indicated that only a longitudinal, randomized controlled trial against baby shampoo would alter their conclusions. Whilst that sort of clinical study is possible, it is proposed here to start with a short-term study to look at the immediate changes induced in the tear film and ocular surface when comparing baby shampoo with Blephasol solution, in a blind, randomized controlled trial.
The alteration of the intestinal microbiota through the use of specific probiotics can improve the clinical course of blepharitis by restoring intestinal and immune homeostasis. The purpose of this study is to define the possible positive impact of probiotics on patients with blepharitis.
Dry Eye Disease (DED) is a multifactorial disease that affects ~15-30 million people in the USA alone. It creates an enormous societal and economic burden, decreases productivity in the workplace, and affects the quality of lives of the people affected by this disease. DED is primarily caused by blepharitis, a chronic inflammation of the eyelid margins. If left untreated, blepharitis results in the obstruction and loss of the glands responsible for tear film production. The standard of care is the use of self-administered at home commercially available products, e.g., eyelid foams, gels, and pads. Although these products are helpful, they have limitations. Patients often require expensive in office procedures, e.g., lid debridement with exfoliation devices or more expensive procedures. The scope of this project is to evaluate the effectiveness of a new self-administered disposable ocular brush used in conjunction with the most common eyelid cleanser. The investigators are looking to see if combining the microexfoliation provided by the brush with the eyelid cleanser is more effective at removing the eyelid debris than the cleanser alone.
To understand the association between facial demodicosis and ocular demodicosis, we plan to enroll patients with facial demodicosis, ocular demodicosis, or both, in order to analyze their clinical presentations, the density of Demodex infestation over facial skin and eyelashes, and possible risk factors of the two diagnoses.
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.
