Filter by:This study will evaluate the safety, efficacy, tolerability, and systemic pharmacokinetics of 3 different doses of topical ophthalmic AGN-223575 suspension compared to AGN-223575 vehicle in patients with dry eye disease.
The purpose of this study is to investigate the ability of an imaging device, developed by AdOM Advanced Optical Technologies Ltd. ("AdOM"). The device allows a three-dimensional imaging of the ocular tissues, specifically the tear film layers and the retinal layers. The device is based on the use of white light. In this initial study, the device will be used to assess the tear film which coats the corneal surface in healthy subjects as well as in moderate-to-severe Keratoconjunctivitis Sicca (KCS) or Dry Eye Syndrome (DES). The ability of the device to assess the retinal layers will be evaluated in the second phase of the study.
Dry eye is a chronic irritating eye condition that affects many people, caused by poor tear quality and insufficient quantity. Treatments are traditionally in the form of artificial tears applied to the ocular surface. However, there is little evidence in the scientific literature that demonstrates their efficacy relative compared to each other, nor how to decide which one might be most effective for an individual patient. Therefore the investigators aim to examine the efficacy of different classes of artificial tears (those designed to increase viscosity, reduce evaporation or to mimic the component balance of the natural tears). In addition, the investigators also aim to determine how the treatment preferred by an individual could potentially have been predicted from their baseline condition.
This study will examine the safety, tolerability, and systemic pharmacokinetics of up to 3 different concentrations of AGN-232411 topical ophthalmic solution in healthy participants and participants with dry eye.
Millions of people suffer from dry eye disease, causing symptoms such as redness, burning, feeling of sand or grit in the eye and light sensitivity. Dry eye disease occurs when your eyes do not produce enough tears or produce poor quality tears. This can happen for a number of reasons, including aging, hormonal changes in women and side effects of diseases or medications. It is now possible to objectively measure the degree of dry eye disease by collecting a tiny sample of tears from the corner of the eye and then measuring the amount of salt in the tears (termed osmolarity). We aim to establish the overall levels of raised and normal tear osmolarity in people presenting to the eye clinic with complaints of dry eye, and relate this to other factors such as symptoms, topical and nutritional medication and dry eye treatment.
This is a randomized, double masked study designed to evaluate the safety of EBI-005 5 mg/mL topical ophthalmic solution given three times daily (TID) compared to vehicle-control over a one year period in subjects with dry eye disease (DED). Approximately 188 subjects will be enrolled to either EBI-005 or vehicle at up to 15 centers in the United States (US) and Canada.
This is a prospective, comparative, contralateral eye study. Patients older than 18 years who have had treatment with topical lubricants for at least 1 month and persist with symptoms of dry eye and corneal staining with fluorescein were included. Patients with dry eye attributable to abnormalities of the eyelids, nasolacrimal obstruction and active corneal infection, as well as patients with severe dry eye were excluded from the study. One eye randomly received a subcutaneous injection of botulinum toxin in the medial part of the lower eyelid, and the other eye received a similar procedure with placebo. The subjective evaluation was achieved with a questionnaire assessing symptoms of dry eye and conjunctivitis, quality of vision and ocular comfort level each eye separately. The objective evaluation included the measurement of the tear film break up time, Schirmer's test and with a modification of the Oxford grading scheme for corneal and conjunctival staining.
The objectives of this study are: - To compare the change in levels of tear proteins and inflammatory mediators pre and post administration between the intranasal and extranasal applications - To compare the goblet cell count following application between the intranasal and extranasal applications - To compare fluorescein tear clearance with the application of the device intranasally and extranasally applications
The purpose of this study is to evaluate the efficacy and safety of Systane® Gel Drops in dry eye subjects following 90 days of QID (4 times/day) dosing.
The investigators aim to assess the effect of blepharoplasty with or without muller muscle resection on the symptoms of dry eye syndrome. this will be an observational study in which patients undergoing the aforementioned surgeries will be followed up and monitored for dry eye symptoms.
