Filter by:The main aim of this investigation is to evaluate the effect of the preservative-free ophthalmic solution IRIDIUM® A gel on the ocular surface of patients with glaucoma or OHT and concomitant DES under multiple long-term topical hypotensive therapy for at least 6 months. The underlying assumption is that ophthalmic solutions as adjuvants for the management of IOP- or glaucoma-associated dry eye may induce a protection of the eye surface with consequent improvement of the symptoms and of the overall quality of life.
This study is to verify the efficacy and safety in the treatment of dry eye syndrome in patients prescribed with Diquasol eye drops as a monotherapy, or in combination with Hyaluron eye drops, or in combination with Hyaluronmax eye drops.
The purpose of this clinical study is to prove that the test drug (TJO-087) is not clinically inferior to the control drug after 32 weeks of administration to patients with suppressed tear production due to moderate or severe dry eye syndrome.
This study wants to use a randomized, single-blind, controlled trial to evaluate the efficacy of receiving acupuncture GB20 or GB20 plus BL2 on alleviating the ocular dryness symptom from dry eye syndrome and Sjögren's syndrome. One hundred dry eye syndrome subjects are composed of 50 dry eye syndrome subjects and 50 Sjögren's syndrome' dry eye subjects, and all are randomized into 40 Group GB20 and 40 Group GB20 plus BL2 (GBL), and 20 Group Waiting list; while we also include 20 healthy controls. Fifty dry eye syndrome subjects are randomized into 20 Group GB20, 20 Group GBL and 10 Group Waiting list in first year; while both Group GB20 or GBL received acupuncture twice a week 8 weeks for efficacy evaluation, and 10 Group Waiting list receive no any acupuncture treatment. And we could use the Whole-genome genotyping, oral microbiota, Schirmer's test, Tear breakup time, Cytokines, OSDI, TCM pattern, Traditional Chinese Medicine (TCM) tongue diagnosis, TCM pulse diagnosis, and TCM heart rate variability for this purpose. In second year, another 50 dry eye syndrome subjects are also enrolled and randomized into randomized into 20 Group GB20, 20 Group GBL and 10 Group Waiting list; while both Group GB20 or GBL received acupuncture twice a week 8 weeks for efficacy evaluation with above outcome measurements, and 10 Group Waiting list receive no any acupuncture treatment. Meanwhile, we also include 20 healthy controls, and we want to find the difference with the comparison between the dry eye syndrome, Sjögren's syndrome and healthy control in second year. Through the analysis for dry eye syndrome and Sjögren's syndrome, we could find the biomarker to differentiate dry eye syndrome, Sjögren's syndrome and healthy control. In the future, this work could be applied for screening and diagnosis of pre-dry eye syndrome and Sjögren's syndrome, and this integrated TCM with Western Medicine plan could be applied for the goal of holistic health care.
To explore the association with TCM pattern and TCM tongue diagnosis for Autoimmune disease and Dry eye syndrome.
This study aims to obtain the lacrimal fingerprint for frequent pathologies of the ocular surface and establish a normative base for each of them.
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.
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.
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):
