NCT ID: NCT04711642 Not yet recruiting - Cataract Clinical Trials

Comprehensive Study on Dry Eye and Ocular Surface Disease Prior and After Cataract Surgery

Start date: January 15, 2021
Phase: Phase 3
Study type: Interventional

Ocular surface disease (OSD), particularly dry eye, is one of the most common conditions seen by ophthalmologists. Dry eye (DE) is a multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear instability. DE significantly reduces quality of life and affects 5-30% of the population. As the proportion of individuals over age 60 increases because of greater life expectancies, we can anticipate the number of people with dry eye will also increase, which represents a major challenging for aging societies, like the Chilean one. In the last few years clinical research on OSD is being intensely focused on diagnostic criteria, treatment strategies, methods used in diagnosis and better correlations between symptoms and clinical test results. All these lines of interest aim to improve the understanding of alterations and consequences occurring in the ocular surface disorders. Diagnostic testing is greatly valuable both for the detection of early changes due to DE and also to grade the severity of surface disease. The most commonly performed tests include the Schirmer test, tear break up time (TBUT), and ocular surface staining. However, newer point-of-care diagnostics tests such as tear osmolarity and matrix metalloprotease-9 (MMP-9) have been shown to have a high sensitivity and specificity in diagnosing ocular surface dysfunction. Given that ocular surface dysfunction has been shown to have an adverse impact on visual function and can worsen after surgery, it is critical to identify and address any tear film and ocular surface abnormalities before cataract surgery. In the setting of preoperative cataract surgery planning, DE disease and meibomian gland dysfunction can impair critical refractive measures such as keratometry values worsening surgical outcomes. To the best of our knowledge there are no ongoing or published studies that have evaluated DE and OSD as evidenced by either an abnormal tear-film parameter (elevated MMP-9 or abnormal osmolarity), or corneal surface and meibography evaluation findings (using novel non-invasive technology) in patients previous and after cataract surgery.

Phase 2 Clinical Trial to Evaluate the Efficacy and Safety of GLH8NDE in Patients With Dry Eye Disease

Start date: April 1, 2021
Phase: Phase 2
Study type: Interventional

This study is a randomized, double-blind, placebo-controlled phase 2 clinical trial to evaluate the efficacy and safety of GLH8NDE in patients with Dry Eye Disease.

NCT ID: NCT04608084 Not yet recruiting - Dry Eye Syndromes Clinical Trials

Platelet Rich Plasma Eye Drops for Treatment of Ocular Surface Disease

Start date: January 2021
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate prospectively the efficacy of topical administration of autologous platelet rich plasma as monotherapy for the treatment of symptoms and clinical signs in cases affected by moderate to severe forms of ocular surface disease

NCT ID: NCT04530864 Not yet recruiting - Dry Eye Disease Clinical Trials

Pre-Surgical Ocular Surface Treatment With Intracanalicular Dexamethasone Insert And Effect On Intraocular Lens Measurement Accuracy

Start date: January 2021
Phase: Phase 4
Study type: Interventional

This prospective study will use a self controlled design for 35 eyes. Patients scheduled to undergo routine cataract surgery in at least one of their eyes will have their pre-surgical measurements performed, IOL calculated and surgery planned. Then they will receive insertion of an intracanalicular dexamethasone insert into the inferior punctum. At 2 weeks (+/- 2 days) post-insertion, patients will return for an identical set of measurements. The IOL will be calculated and the surgery planned based on post-insert data. The insert will be removed if present (manually or via saline irrigation). This self controlled design allows for greater control of potential confounders tied to participants' systemic and ocular health.

NCT ID: NCT04411615 Not yet recruiting - Dry Eye Clinical Trials

Heidelberg In Vivo Confocal Microscopy to Evaluate the Ocular Surface Disorders of Healthy and Diseased Individuals

Start date: July 31, 2019
Phase:
Study type: Observational

In vivo confocal microscopy (IVCM) has been used in clinical settings for more than 25 years, and is noninvasive, rapid and easily repeatable technique to investigate ocular surface disorders. It enables morphological and quantitative analysis of ocular surface microstructure. [1-3] As the technology advances, new IVCM machine, Heidelberg Retinal Tomograph with Rostock Corneal Module (HRT-RCM), was developed. Hardware and software modifications and acquisition techniques continue to expand the applications of the HRT-RCM for quantitative in vivo corneal imaging at the cellular level. The new software can access the corneal nerve more accurate. Here the investigators proposed this Institutional Review Board (IRB) to collect healthy persons and cases of different systematic diseases as well as etiologies of ocular surface diseases.

NCT ID: NCT04000789 Not yet recruiting - Dry Eye Syndromes Clinical Trials

The Effect of Combination of Vitamin A, Vitamin E, Sodium Hyaluronate 0.15% Eye Drop Compared With Sodium Hyaluronate 0.1% Eye Drop to Tear Film Stability and Conjunctival Goblet Cells Density in Patient With Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR)

Start date: July 2019
Phase: N/A
Study type: Interventional

Commonly know that one of the complications caused by Diabetes Mellitus (DM) is microangiopathy. Microangiopathy in the long term may lead to neuropathy of the corneal nerves. Neuropathy of the cornea will lead to dry eyes in DM patient. One of the artificial tears used in treating dry eyes is sodium hyaluronate. But until recently no research had been done in examining the effect of giving combination of sodium hyaluronate, vitamin A and vitamin E in dry eyes. The antioxidant, and capability of vitamin A and E in promoting cell proliferation may alleviate the symptoms of dry eyes. In this paper we used Ocular Surface Disease Index (OSDI), Tear Break Up time, Schirmer I test and impression cytology to assess baseline and 28 days post therapy in patient with Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR)
