Active clinical trials for "Keratoconjunctivitis Sicca"

Primary Sjögren's syndrome is a chronic autoimmune disease that primarily involves exocrine glands, most commonly manifested in dry eye, dry mouth, and in other systems of the body.

The objective is to compare the USL and placebo in terms of efficacy and safety, and to determine the appropriate dosage.

To explore the association with TCM pattern and TCM tongue diagnosis for Autoimmune disease and Dry eye syndrome.

Dry eye disease (DED) is the most prevalent ocular surface disease worldwide. Standard treatments like artificial tears show limited effect. Regarding the ultrasonic atomization, the ultrasonic nebulizer produces consistent steam from the solution with a treatment effect delivered to the ocular surface. We aim to evaluate the effectiveness and safety of traditional Chinese medicine (TCM) ultrasonic atomization as an adjuvant treatment for DED. This is a randomized double-masked, active- and placebo-controlled trial. 200 subjects will be equally assigned to the herbal compound decoction(CD) group, dendrobium caulis (DC) group, houttuynia cordata (HC) group, placebo atomization(PA) group, and artificial tear (AT) group by stratified permuted block randomization. Subjects of CD, DC, HC, and PA groups will receive TCM ultrasonic atomization treatment (6 times/week). All patients will receive hypromellose 0.3% w/v lubricant eye drops for a 1-week wash-out and a 4-month follow-up period. Outcomes included non-invasive tear break-up times, corneal and conjunctival fluorescein staining, and other dry eye-related parameter examined by LipiView II Ocular Surface Interferometer, OCULUS® Keratograph 5M, and slit lamp biomicroscope evaluated by masked clinical assessors at baseline, week 1, 2, 3, 4 and month 2, 3, 4. The other subjective questionnaires like the Ocular Surface Disease Index (OSDI) questionnaire are also selected.

To demonstrate that DMSt + RF improves eye blink quality in subjects with dry eye disease

To investigate prevalence of dry eye disease in Norwegian patients with age-related macular degeneration receiving intravitreal injections, as well as to reveal possible risk factors of DED in this population.

A Multi-Centre, Randomised, Controlled, Masked Phase 2 Study of the Safety and Efficacy of KIO-101 Ophthalmic Solution, versus Vehicle Control in the treatment of Dry Eye Disease in Patients with Autoimmune Disease

This is a single center double-masked study with up to four visits. Subjects who have been diagnosed with dry-eye syndrome at Flaum Eye Institute will be enrolled. The purpose of the study is to determine if using platelet rich plasma drops can improve clinically significant dry eye in patients and determine if there is a difference with using two different uses of the plasma tear drops: platelet rich plasma tears and plasma tears without platelets.

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.
