Filter by:This study is being conducted to evaluate the short-term (1 month) safety and effectiveness of a single TearCare procedure to treat adult patients with dry eye disease. NOTE: All sites have been selected for this study.
Rationale: Serum eye drops (SEDs) are used to treat patients with severe signs and symptoms of dry eyes and other corneal defects. Serum is used in severe ophthalmic cases where conventional treatment and/or eye drops (artificial tears) have insufficient effect. The use of SEDs in dry eye patients usually has a rapid effect. Most patients claim the effect to be instantaneous, and most symptoms improve within 48-72 hours. There is evidence suggesting that substances in serum may help in the healing of epithelial defects, such as epidermal growth factor, fibroblast growth factor, fibronectin, and/or vitamin A. However, the precise serum factor responsible for alleviating the patient's complaints is currently not known. SEDs are considered as a blood product under EU blood legislation (Directive 2002/98/EC), as well as in New Zealand and Australia. Commonly, autologous SEDs are used, but they are replaced more and more by allogeneic SEDs prepared from donor serum. Allogeneic SEDs are derived from healthy voluntary, non-remunerated male donors with blood group AB, and have the benefit of blood bank controlled quality. They can be delivered from stock and are therefore quickly available for each patient. For application of eye drops, generally administration systems with a drop size of 40 to 50 µl are used, further on referred to as conventional sized eye drops. From previous studies done with medicinal eye drops, it has been shown that smaller eye drops, so called micro drops, can be just as effective and sometimes even superior to conventional drops for treatment of eye disease. If micro drops are just as effective or maybe even superior to conventional sized eye drops is currently unknown for the use of SEDs. This study will compare the feasibility and effectiveness of allogeneic serum micro eye drops using the mu-Drop applicator to the conventional sized allogeneic eye drops using the Meise applicator. Both systems have a closed manufacturing system. Objective: The main objective is to determine whether the administration of allogeneic serum micro eye drops is non-inferior in terms of effectiveness and safety as compared to the conventional sized drops. Main study parameters/endpoints: The primary endpoint is the improvement in OSDI score by using SEDs (OSDI score after treatment minus OSDI score before treatment), independent of the drop size, showing non-inferiority for the use of micro drops as compared to conventional sized drops.
Photophobia is a common and disabling symptom in patient with dry eye syndrome. The aim of this study is tried to better understand this complain analyzing brain activation during a luminous stimulation to highlight modification of cortical activation.
Dry eye disease (DED) is a common ocular disease, especially in the elderly population. Despite many treatment approaches, instillation of topical lubricants remains the mainstay of therapy. However, most of the topical lubricants available are not very well characterised and data about efficacy is sparse. The aim of the present pilot study is to investigate the effect of topically administered lipid based eye drops on tear film lipid layer thickness in subjects with dry eye disease, Meibomian gland dysfunction, blepharospasm and healthy subjects. Tear film lipid layer and tear film thickness will be assessed using the Lipiview II interferometer and OCT. Measurements will be performed before instillation of the eye drops and every 10 minutes after instillation for one hour. One eye will receive lipid based eye drops, the other eye will receive no eye drops and will be used as control. The study eye will be chosen randomly. In addition, Dynamic Meibomian gland imaging, Schirmer I test, corneal fluorescein staining and determination of tear break up time (BUT) will be performed
Modifications of cell surface markers (including EMMPRIN) were observed in conjunctival epithelial cells during dry eye syndrome ; this study aims to describe the modifications of the repartition of these cell surface markers before and after initiation of a treatment.
Subjects with dry eye are enrolled at two ophthalmic centers and randomly assigned to a laser acupuncture group and control group under conventional treatment with artificial tears. The effects of laser acupuncture therapy for patients with dry eye are investigated.
Meibomian gland dysfunction (MGD) is among the leading causes for dry eye syndrome (DES), affecting millions of people worldwide. We have shown in a previous study that tear film thickness (TFT) is reduced in patients with DES and that this reduction correlates with tear break up time (BUT) as well as with the severity of subjective symptoms. Even though systemic tetracyclines as well as topical azithromycin can be used for the treatment of MGD, it seems that topical azithromycin is more effective than tetracyclines and also has the advantage of better tolerability. The hypothesis of the present study is that topical treatment with azithromycin leads to a more pronounced increase in TFT compared to oral doxycycline in patients with DES caused by MGD. The objective of this study is to compare the effect of treatment with topical azithromycin or oral doxycycline on tear film thickness in patients with DES caused by MGD.
This is a first-in-human phase I/II randomized, double-blind, placebo (vehicle)-controlled, multicenter study to assess the Safety and Efficacy of AVX-012 Ophthalmic Solution in subjects with Mild-to-Moderate Dry Eye Syndrome. The study consists of two parts (part A and part B):
The purpose of this study is to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls. There are two phases in this study. The first phase is an observational phase which studies the eye in various conditions. The second phase is an interventional phase which studies the changes in the eyes after taking an over-the-counter medical food (Ocufolin) for 6 months.
This trial is designed to evaluate the efficacy of walnut shell glasses moxibustion for dry eye syndrome compared with sodium hyaluronate eye drops.
