Filter by:Primary Objective - To assess the proportion of patients with Sjögren's dry eye who demonstrate impaired corneal sensitivity. Secondary Objectives - To assess corneal sensitivity via Cochet-Bonnet esthesiometer. - To assess tear secretion via Schirmer I test. - To assess OPAS questionnaire results.
Dry eye disease, or keratoconjunctivitis sicca, is one of the most common diseases encountered at ophthalmologic clinics. Patient with dry eye disease commonly presented foreign body sensation, red eye, blurred vision, etc. Numerous treatments for dry eye disease are proposed due to its multifactorial etiology. Sjögren syndrome, which is one of the main etiologies of dry eye disease, is an autoimmune disease characterized by dysfunction of lacrimal and salivary glands. Although dry eye status can be easily examined by ocular surface staining, the methods quantifying salivary flow rate are hard to performed clinically, such as salivary gland scintigraphy and sialometry. Furthermore, disease activity could only rely on serum markers or salivary gland ultrasound. Recently, a portable device measuring salivary conductivity is believed to assess fluid status and renal function. Interestingly, the composition of salivary electrolytes in patients with Sjögren syndrome is different from those with other causes of hyposalivation. Thus, this study aims to evaluate whether salivary conductivity in combination with ocular surface staining can be a non-invasive diagnostic test for primary Sjögren syndrome among people with dry eye disease.
The objectives of this study are to compare the efficacy and safety of tanfanercept ophthalmic solution 0.25% and 1.0% to vehicle for the treatment of DED.
In this study, two treatments typically used for dry eye disease will be tried for contact lens users to see if their symptoms when they use their contact lenses get better. Cyclosporine is a drop that is used for long-term management of the inflammation and Intense pulsed light (IPL) is a treatment done in a clinic to improve the health of the eyelid glands. The main question in this study is: Does the combined treatment of cyclosporine and IPL improve the symptoms and the dry eye signs of contact lens wearers? All the participants will receive the cyclosporine drops for 4 months twice a day. The research team will split the group of participants in two, half receiving the real IPL treatment and half receiving a sham IPL treatment during the last two months of the study. This will allow to compare the two groups to see how IPL helped. The dry eye tests will be done at the start of the study, after two months and after 4 months. The tests will include a dry eye symptoms questionnaire, measures on the tears, the structures of the front of the eye and the eyelids.
A Randomized, Double-Masked, Vehicle-Controlled Parallel Group Clinical Trial to Assess Efficacy and Safety of 0.25% Reproxalap Ophthalmic Solution Compared to Vehicle in Subjects with Dry Eye Disease
Phase 2 study to assess the efficacy of topically administered eyedrops of INV-102 during 4-week repeat dosing in subjects with moderate to severe dry eye disease.
Application of tear ferning test for clinical dry eye diagnosis
The goal of this clinical trial is to evaluate the efficacy and safety of C.STIM, an intense pulsed light device to treat signs and symptoms of dry eye disease. The main question it aims to answer is: • Difference of the evolution of Tear Break-Up time (TBUT) between the 2 arms of the study (placebo and treated). Researchers will compare treated group and placebo to respond to the main question. Participants will assess to an inclusion visit (disease evaluation purpose) and then four IPL treatment visit to finish with the last visit (disease evaluation purpose).
The objective of this trial is to evaluate the effect of cyclosporine ophthalmic solution, 0.1% on corneal endothelial cell health in comparison to a hypotonic saline solution in subjects with Dry Eye Disease (DED)
The goal of this interventional, monocentric, prospective, single-masked, case-control study is to evaluate the efficacy of Thealoz Duo (artificial tear containing trehalose 3 g and hyaluronic acid 0.15 g) in comparison to a saline solution (Hydrabak containing Sodium Chloride 0,9 g, Sodium Dihydrogen Phosphate Dihydrate, Disodium Hydrogen Phosphate Dodecahydrate), to reduce the signs of ocular discomfort and ocular side effects in patients who have received Intravitreal injections. The main questions it aims to answer are: - can ocular instillation of Thealoz Duo solution, 1 week before intravitreal injection, in a fixed dose regimen, prevent ocular surface changes and dry-eye signs? - can ocular instillation of Thealoz Duo solution, up 3 months after intravitreal injections, in a fixed dose regimen, reduce ocular surface changes, and dry-eye signs with improvement of quality of life and quality of vision? Each participant will be randomized into each of two arms: 1. TREATMENT ARM: patients who will receive the instillation of Thealoz Duo, 10 ml, 1 drop, 4 times/day; 2. CONTROL ARM: patients who will receive the instillation of saline solution (Hydrabak), 10 ml, 1 drop, 4 times /day; The decision of inclusion of a control group should minimize the risk of breaking the blinding condition by affecting the consistency and reliability of the outcome's achievement. In any case, the instillation of saline solution should not alter the ocular surface.
