Active clinical trials for "Dry Eye Syndromes"

This is a prospective, single site, randomized, double masked, comparator-controlled study designed to evaluate the efficacy of lifitegrast ophthalmic solution 5% in treating the symptoms of dry eye in soft contact lens wearers as compared to control. We hypothesize that there will be a significant improvement in dry eye symptoms in contact lens wearers using lifitegrast as compared to those being treated with control (lifitegrast vehicle).

Dry eye disease is multifactorial, ocular inflammatory condition causing irritation, stinging sensation, uneasiness and blurring. Non-Sjogren syndrome occurs due to absent or dysfunction of lacrimal gland. Fat soluble vitamin D act as an agent against inflammation and its deficiency may result in various inflammatory diseases including dry eye. Purpose of this study is evaluation of vitamin D3 supplementation role in treating non-Sjogren dry eye along with conventional treatment by using artificial tears in patients with hypovitaminosis D. A prospective study was conducted in Rural health center(RHC) Buchal Kalan on 108 patients presenting with non-Sjogren dry eyes and low serum vitamin D levels. Patients were subjected to the following examination; best corrected visual acuity (BCVA), slit-lamp examination, applanation tonometry, fundoscopy, tear breakup time (TBUT) after fluorescein staining, Schirmer tear test, numerical pain rating scale (NPRS) and ocular surface disease index (OSDI) score on day 0, 15, 30, 60 and 90. Vitamin D levels was assessed by electrochemiluminescence immunoassay (ECLIA) based analyzer. The sample was randomly divided into two groups by non-probability purposive sampling. Group 1 received only artificial tears 4times/day while group 2 were given oral vitamin D3 supplementation of 6000 international unit (IU) daily along with artificial tears. Impact of oral vitamin D3 supplementation on non-Sjogren dry eyes was assessed by comparing means of ocular parameters of both groups over different period of time by using Mann-Whitney Test and Friedman Test.

The objective of this study is to evaluate the safety and effectiveness of OC-01 Nasal Spray as compared to placebo on signs and symptoms of dry eye disease.

The purpose of this study is to assess the safety and effectiveness of SI-614 solution compared with placebo solution in treating patients with dry eye.

The purpose of this study is to evaluate the efficacy of LME636 compared to vehicle in the reduction of ocular symptoms and to evaluate the safety and tolerability of LME636, when administered topically for up to 42 days, in subjects with severe dry eye disease.

This study will evaluate the safety and efficacy of a new eye drop formulation in patients with dry eye disease.

The "dry eye syndrome" DES is a highly prevalent ocular disease, in particular in the elderly population. One mainstay of therapy for patients suffering from DES is the use of topically administered lubricants. However, despite many efforts, no "ideal" formulation has yet been found. Recently, Croma Pharma has introduced chitosan-N-acetylcysteine eye drops, designed for treatment of symptoms related to DES. Chemically, chitosan is a polycationic biopolymer with favourable biological properties such as high biocompatibility and low toxicity. Additionally, the new formulation comprises N-acetylcysteine, which has been used in ophthalmology because of its mucolytic properties for several years. Based on theoretical considerations, one can hypothesize that the new chitosan derivative may show an increased adhesion to mucins of the ocular surface and may therefore be particularly beneficial in reducing the symptoms associated with DES. We have recently shown in a phase I trial that single instillation of chitosan-N-acetylcysteine eye drops is well tolerated in young healthy subjects. However, no data is yet available about safety and tolerability of chitosan-N-acetylcysteine in subjects wearing contact lenses. This is of special interest because the tear film is critical to successful contact lens wear. Disturbances of the quantity or quality of the tear film results in intolerance of contact lens wear and possible damage to the ocular surface. This trial seeks to investigate the local tolerability and possible ocular discomfort of chitosan-N-acetylcysteine eye drops after repeated instillation .

The purpose of the study is to evaluate the safety and efficacy of lifitegrast ophthalmic solution compared to placebo in the treatment of dry eye.

The aim of this pilot study is to compare the analgesic effect of SYL1001 versus placebo in patients with ocular pain associated with Dry Eye Syndrome. General and local tolerability are also evaluated.

The purpose of this study is to determine efficacy and safety of Haporine-S eye drop for the patients with moderate to severe dry eye disease in a multicenter phase III clinical trial.
