Active clinical trials for "Keratoconjunctivitis Sicca"

The objective of this study is to evaluate the efficacy of Rohto Dry-Aid® in comparison to Systane® Ultra on visual function and tear film stability in patients diagnosed with Dry Eye.

The purpose of this study is to determine whether SYL1001 ophthalmic solution is safe and effective in the treatment of signs and symptoms of Dry Eye Disease.

Background: Dry eye disease (DED) is a common condition causing burden on visual function and reducing quality of life. Corticosteroids and/or cyclosporine eye drops are able to improve DED symptoms, however, side effects of immune suppression and cost lead patients often to suspend treatment. Consequently, is important to identify therapies alleviating DED symptoms. A randomized, controlled, single masked study, was performed in 40 patients affected by mild to moderate DED, to evaluate efficacy and safety of a collyrium based on cross-linked hyaluronic acid (XLHA) added with Coenzyme Q10 (CoQ10) in comparison to an eye drop considered a gold standard for tear substitutes, based on hyaluronic acid (HA) 0.15%. Methods: eye drops were administered four times a day for 90 days to enrolled subjects divided in two groups: group A treated with XLHA+CoQ10, group B treated with HA. Ocular Surface Disease Index (OSDI) questionnaire, visual acuity, intraocular pressure (IOP), fundus exam, tear break-up time (TBUT), corneal and conjunctival fluorescein staining, corneal esthesiometry, corneal confocal microscopy, were performed at different visits until the 90th day.

The objective of this study is to assess safety and efficacy of DE-089 ophthalmic solution in patients with dry eye disease in Taiwan.

The primary objective of this study is to evaluate the efficacy of REMOGEN® OMEGA in reducing Dry Eye Syndrome (DES) symptoms.

The purpose of this Phase 1/2 study is to compare the safety and tolerability of four times a day (QID) dosing of a non-preserved topical ocular drop formulation of 10 vol/vol % and 30 vol/vol % of FD hPL to vehicle control eye drops in patients with Dry Eye Disease (DED) secondary to Graft vs. Host Disease (GvHD).

A Multi-Center, Phase 2b, Randomized, Double Masked, Parallel-Group, Vehicle-Controlled, Clinical Study to Assess the Safety and Efficacy of Reproxalap Ophthalmic Solution (0.25% and 0.1%) Compared to Vehicle in Subjects with Dry Eye Disease

The objective of the Phase 2 study is to compare the safety and efficacy of cis-UCA Ophthalmic Solutions to placebo for the treatment of the signs and symptoms of dry eye.

Eyes with abnormal tear film function have been found to show larger optical aberrations than normal eyes which may be attributed to the unstable and irregular tear film, uneven ocular surface, and increased scatter due to the exposure of the rough surface of corneal epithelium after tear break-up. These hypotheses have been supported by the findings that instillation of artificial tears (sodium hyaluronate preparation) in dry eye patients reduces both corneal and ocular aberrations, improving the optical quality of the retinal image. However, the previous studies only evaluated the short-term effects of a single administration of an artificial tear but did not determine the duration of action or inflection point at which the ocular aberrations increase back to baseline. Also, there has clearly been no such clinical trial that has been a well randomized controlled study to date. This report is the first randomized controlled trial that investigated the long-term effects of a single dose of sodium hyaluronate-based artificial tears on wavefront aberrations in patients with dry eye.

Purpose To try to establish whether lid-parallel conjunctival folds (LIPCOF) can be influenced by increased lubrication with rewetting and lubricating eyedrops containing hydroxypropyl-guar, which has proven lubricating effect. Methods During summer and fall of 2009, 16 ophthalmologists from various regions of Croatia investigated the effect of topical therapy with lubricating eyedrops on the signs and symptoms of dry eye, with the special emphasis on lid-parallel conjunctival folds (LIPCOF). 229 patients were enrolled in the study. Results After 14 days of therapy with lubricating eyedrops containing hydroxypropyl-guar, statistically significant reduction of LIPCOF grade was observed, as well as the reduction of symptoms and other signs of dysfunctional tear syndrome (TBUT, Schirmer test, conjunctival hyperemia). Conclusion Results of this study have shown positive influence of lubricating eyedrops containing hydroxypropyl-guar on signs and symptoms of dysfunctional tear syndrome even after only 14 days of treatment. It is of particular interest that LIPCOF grade was statistically significantly decreased, pointing at increased friction and decreased ocular surface lubrication as possible causes of its appearance. Having this in mind, every clinician involved in dysfunctional tear syndrome treatment must also think about lubrication as integral part of treating this condition.
