Active clinical trials for "Dry Eye Syndromes"

The use of povidone iodine solution for prophylaxis of endophthalmitis is well established for intraocular procedures like cataract surgery and for injections of anti-VEGF agents for retinal diseases such as age-related macular degeneration. Unfortunately iodine is unfriendly to the ocular surface, and when repeated often enough (some patients require up to monthly injections of anti-VEGF agents for the entire year), corneal epitheliopathy and secondary dry eye results. Unfortunately, there is no good alternative to cleaning patient's eyelid at the moment. Ocudox is a relatively new antibacterial product (spraying on eyelid wipe) which contains Neutrox (pure hypochlorous acid) that kills many microbes, but remain very friendly and non-toxic for the ocular surface.

Discomfort with contact lens wear is the biggest reason why people stop wearing contact lenses. The investigators believe that inflammation is one of the causes of discomfort, and by blocking the inflammation using lifitegrast, the investigators may be able to relieve some of that discomfort. This study will enroll 50 subjects with contact lens discomfort and will receive lifitegrast to use over a period of approximately 3 months.

This study aims to evaluate the short and long-term effects of skin-only and skin+muscle excision blepharoplasty on corneal nerves, dry eye parameters, meibomian glands, and eyebrow position.

Importance: Lipid layer thickness (LLT) reflects the lipid components of tear film, but is affected by the mucocutaneous components. This study investigated the therapeutic effect of the treatments for aqueous-deficient dry eye (ADDE) on LLT. Objective: To investigate the effect of ADDE and its treatments on LLT measurements by tear interferometry. Design, Setting, and Participants: This prospective comparative interventional study included 152 eyes from 152 patients with ADDE. Interventions: Participants were classified into four groups: control group (Group 1), 3% diquafosol group (Group 2), punctal plug insertion group (Group 3), and combined treatment group (Group 4). Main Outcomes and Measures: Average LLT (LLTave) was measured using a LipiView® II tear interferometer at baseline and one month after treatments.

After topical installation of one drop of 0.3% commercially available ofloxacin (Oxatrex®) four times at intervals of 15min in catarract patients with Dry Eye Disease, aqueous humour samples will be collected intraoperatively, one hour after the last installation. Concentration of ofloxacin in aqueous humour will be measured by HPLC-MS/MS.

Dry Eye Syndrome (DES) is a common condition that affects approximately 20% of adults aged 45 and older. Although several clinical tests for the diagnosis and monitoring of DES are available, currently no gold standard for the assessment of DES exists. It has, however, been hypothesized that the assessment of tear film osmolarity may be a new and promising approach of an objective and non-invasive method for diagnosis and monitoring of treatment success. Recently, a new commercially available instrument (TearLab®, OcuSens Inc, San Diego, USA) for the assessment of tear film osmolarity has been introduced. This instrument allows for the easy and non-invasive determination of tear film osmolarity. Unfortunately, no data about reproducibility are yet available. Consequently, the current study sets out to investigate the short time reproducibility of tear film osmolarity measurements using the TearLab® instrument.

Our primary aim is to determine whether pulsed light therapy (PLT) is effective in reducing symptoms and improving clinical stigmata of dry eye syndrome (DES) associated with meibomian gland dysfunction (MGD) in patients with facial rosacea (which includes ocular rosacea). The uses of PLT are for treatment of rosacea, hair removal, pigmented lesions, and skin telangiectasias. The risks include the potential for transient sunburn-like sensations (i.e. redness, burning sensation) and particularly if not used properly, the potential to cause burns, blistering, scarring, and pigmentary changes.

The purpose of this research is to: Evaluate the safety and efficacy of a steroid eye drop (Lotemax) in patients who have been diagnosed with graft-versus-host disease (GVHD), which is a complication that may occur after bone marrow transplant where the newly transplanted material attacks the patient's body and may cause eye dryness. Assess the safety and efficacy of Lotemax in decreasing the eye's reaction to the process in GVHD before the patient undergoes bone marrow transplant. Compare how well Lotemax works in decreasing the process in GVHD with an immunosuppressive eye drop (Restasis), which has been commonly used in the treatment of this condition.

To evaluate the effect of cyclosporine eye drop before cataract surgery for the prevention of post cataract surgery dry eye syndrome.

This is a clinical trial where 44 subjects dry eyes were instilled with Virgin Coconut Oil (VCO CL) using contact lenses as its vehicle. All subjects are healthy subjects with no other ocular diseases except for having some dry eye symptoms (included with McMonnies questionnaires). Parameters measured at baseline and after 15 minutes of insertion and were compared. The control eyes were inserted with contact lenses soaked in saline (CCL). The eye that wears the VCO CL or the CCL were chosen randomly by masked operator. At the end of this study, the parameters measured will indicate if the VCO CL was able to retain tears in the eye and remove the dry eyes symptoms.
