Filter by:The use of photobiomodulation or low-level light therapy (LLLT) in the ophthalmic field stemmed from dermatology which has shown impact on skin blood flow and regeneration. There has been a rise in clinical interest with emerging evidence in the benefits of photobiomodulation in managing chronic inflammatory conditions such as dry eye disease including improvements in ocular discomfort symptoms, tear film stability and tear volume. Despite the observed clinical benefits, limited research has been done to compare photobiomodulation utilising different wavelengths, as most research on dry eye disease has focused on red wavelengths. It has been purported that blue wavelengths may disrupt microbial growth while red wavelengths stimulate energy production and hence increase heat in the affected tissues, although research into these differential impacts at the ocular surface and external eye has been limited. Hence, the aim of this exploratory clinical trial is to compare the impact of using LLLT incorporating red versus blue wavelengths on eyelid haemodynamics and microbiome, as well as conventional ocular surface measures of patients with dry eye disease and blepharitis (inflammation of the eyelids). Participants with dry eye disease, oil gland disruption and blepharitis will receive 3 treatments with these LLLT, each separted by 1 week apart, and followed up to 1 month after the final treatment session. Participants will be randomised to either of 3 groups: Red light only group, Red + Blue light group, or a sham treatment group.
This is a phase I study evaluating safety and tolerability of PRO-229 ophthalmic solution through he incidence of unexpected adverse events, changes in Best Corrected Visual Acuity (BCVA), incidence of chemosis, and changes in ocular surface staining using the Sjögren's International Collaborative Clinical Alliance (SICCA) Ocular Staining Score (OSS) scale compared to Lagricel® Ofteno PF in clinically healthy subjects.
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
In this study the investigators plan to enroll three groups of patients: non-Sjogren's dry eye, Sjogren's dry eye and controls. The study has the following primary goals: 1. To determine whether dry eye is associated with reduced corneal sensation 2. To determine whether reduced corneal sensation is due to the severity of the dry eye, the type of dry eye (primarily aqueous deficient versus primarily evaporative) or entirely related to the presence of Sjogren's 3. To determine whether corneal sensation is associated with ocular or systemic pain symptoms Additionally, the study aims to compare the novel corneal esthesiometer measurements to confocal biomicroscopy findings in determining neurotrophic keratitis (NK) and assess correlations between corneal sensation.
This is a Phase 3, randomized, double-Masked, vehicle-controlled, multi-center study designed to evaluate the safety and efficacy of 5% VVN001 Ophthalmic Solution versus vehicle in Chinese subjects with dry eye disease.
The research project titled "The Impact of Immersive Virtual Reality Training on Adult: Motion Sickness, and Ocular Surface: A Pilot Study" aimed to evaluate the initial safety impact of head-mounted virtual reality (HMVR) devices with virtual reality amblyopia training games on postural stability, motion sickness, and ocular surface in healthy adult participants. 38 adults (76 eyes) with normal corrected vision and stereo vision were recruited. All subjects used HMVR device for two consecutive training sessions (30 minutes each, 10 minutes intervals). Before training, after the first training and the second training, recorded the results including best corrected visual acuity (BCVA), ocular position, stereo vision, postural stability, non-invasive tear breakup time (NITBUT), tear meniscus height (TMH), red eye analysis, lipid layer classification (TFLL), eye blink frequency, eye surface temperature, simulator sickness questionnaire (SSQ) score, ocular surface disease index (OSDI) dry eye questionnaire score, visual quality questionnaire score and visual fatigue questionnaire score.
This research assesses the tear performance of five distinct types of soft contact lenses commonly found in the market. The study involves contact lens participants, all of whom are students enrolled at UKM. Before the study, participants were instructed to discontinue wearing their usual contact lenses for two weeks. The lenses utilized in this clinical trial all possess current refractive power. Participants are required to wear the lenses for an entire day only. Upon completion of the study, participants will be requested to complete a brief questionnaire.
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).
