Filter by:The aim of this study is establish the reliability and clinical utility of microneuromas as identified via in vivo confocal microscopy as the diagnostic biomarker for NCP.
Eyeliner is one of the most common eye cosmetics. The main ingredients are titanium oxide, pigment, grease and preservative. The user will apply the eyeliner to the eyelid and eyelash. With the blinking again and again, the components of the eyeliner may enter the tear film and continue to act on the eye surface. Therefore, the investigators suspect that the use of eyeliner may be an important factor leading to dry eye disease. In order to explore the relationship between the use of eyeliner and dry eye disease, the investigators plan to collect eye surface characteristic data of the two groups of people who use eyeliner and who do not use it.Then use Raman analysis to explore whether the use of eyeliner will lead to changes in tear composition.The investigators intend to analyze the difference of tear composition between the two groups to understand the relationship between the change of tear composition and tear film stability.So that the investigators can identify the risk factors of dry eye disease, and provide basis for prevention and early treatment.
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
The purpose of this interventional study is to assess safety, patient tolerability, plug retention rate, and preliminary efficacy in improving the symptoms of Dry Eye Disease (DED) of EXP-TC tacrolimus releasing punctal plug. The main questions it aims to answer are: 1. The safety of using EXP-TC plug following all study adverse events 2. The number of patients with Adverse Events related to the us of EXP-LP plug 3. The number of patients discontinuing the study due to plug discomfort 4. The total patients with plugs remained during the 3-months study duration from plug insertion 5. Exploratory: change from baseline in the study eye to follow-up visits in various Dryness clinical measurements. The change of measurements from baseline will also be compared between the study and fellow control eye (receiving artificial tears only, 0.15% sodium hyaluronate).
To evaluate the efficacy and safety of Jing Fang Wu Mei Wan Jiawei Fang in the treatment of idiopathic blepharospasm using a clinical randomized controlled trial method.
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 study aimed to evaluate 1) if levels of the glycocalyx membrane mucins, including MUC1, MUC4, MUC16 and MUC20, are altered in conjunctival cells of visual display users With and Without Dry Eye Disease, and 2) if mucin levels correlate with dry eye clinical diagnostic data.
to analyze the clinical and tear molecular profile up to 6 months after FS-LASIK surgery
In recent years, many scholars have studied the ocular surface damage of patients with dry eye disease（DED）after FS-LASIK, but there has been a lack of comprehensive observation and research on the relationship and difference between dry eye （DE）patients with and without LASIK. Therefore, the purpose of this study was to investigate the characteristics of ocular surface and cytokines after FS-LASIK, and further explain the pathogenesis of chronic dry eyes after FS-LASIK. In addition, we will also compare clinical characteristics and tear neuropeptide concentrations in patients with dry eye disease (DED) with and without chronic ocular pain following FS-LASIK, and to investigate correlations between ocular pain, clinical characteristics, and tear neuropeptide levels.
