Active clinical trials for "Blepharitis"

The purpose of this study is to compare the safety and efficacy of TP-03, 0.25%, an eyedrop, BID vs TID dosing regimens for the treatment of meibomian gland dysfunction in patients with Demodex lid infestation.

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.

This is a multi-center, multidisciplinary, open-label, randomized controlled prospective clinical study.

The purpose of this study is to evaluate and compare the effect of two dosing regimens, BID versus TID dosing, of an Exploratory Vehicle (EV) on meibomian gland dysfunction (MGD) in patients with Demodex lid infestation.

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 Phase III main study is a randomized, controlled, multicenter, double blind, trial to evaluate the efficacy and safety of TP-03 (lotilaner ophthalmic solution, 0.25%), for the treatment of Demodex blepharitis in Chinese patients. The PK sub-study is a single-arm, open-label trial to evaluate systemic TP-03 in whole blood following topical ocular administration

In vivo confocal microscopy (IVCM) used in tertiary care ophthalmology centers is performed with two reflectance microscopes attached on a mounting with limited movement along the XYZ axes. Consequently, ocular diseases in the central area have been described (mostly cornea and adjacent conjunctiva). Two dermatology IVCM (an handheld small IVCM and a multifluorescent one) present significant innovations that the investigators want to assess in ophthalmology for the diagnosis of conjunctiva, cornea, eyelid and lachrymal tract diseases. The handheld IVCM have unlimited degrees of freedom and a small diameter objective. It could dramatically increase the area accessible to IVCM (whole conjunctiva, eyelids, proximal lachrymal tract) (part 1 of the present study). The fluorescent IVCM allows the use of a wide range of fluorescent markers liable to increase the specificity of the diagnosis by revealing staining patterns corresponding to a specific disease and not to others (part 2 of the study)

The purpose of this study is to compare the safety and efficacy of azithromycin ophthalmic solution, 1% versus vehicle over a four-week treatment period in treating the signs and symptoms of subjects with blepharitis and to evaluate the clinical course of the condition under study.

Objective: To investigate the efficacy of microblepharoexfoliation by BlephEx™ as an adjunct to eyelid cleansing in the treatment of anterior blepharitis and to validate the grading score of lid contamination to describe the severity of anterior blepharitis. Design: A prospective, randomized, paired-eye trial. Methods: One of patients' eyes will be randomized into the microblepharoexfoliation group which will use the BlephExTM device during the in-house lid cleansing procedure. The other eye will be in the control group which will receive conventional lid cleansing. The parameters indicating the efficacy of the microblepharoexfoliation procedure including the symptom scoring system; the Standard Patient Evaluation of Eye Dryness Questionnaire (SPEED), lashes contamination, lid margin redness, number of preservative free artificial tears used per day, meibomian gland quality and expressibility will be recorded at the screening visit and 3-week follow-up visit. The patient will be instructed to do warm compression and lid cleansing at home once a day with Optase eyelid scrubs for 3 weeks on both eyes before follow-up.
