Active clinical trials for "Eye Diseases"

A clinical trial using Senofilcon A daily lenses in the treatment of moderate to severe dry eye. This a comparison between signs and symptoms prior to and during treatment.

The purpose of this multicenter randomized clinical trial is to evaluate the adjunctive effect of repeated low-level red-light therapy (RLRL) and orthokeratology (ortho-k) on myopia control in ortho-k non-responders who have undergone ortho-k treatment but were still experiencing fast myopia progression.

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.

The study is conducted to evaluate the efficacy of digital blue light blocking filter in improvement of clinical indices of dry eye and ocular symptoms related to dry eye. Introduction: Dry eye disease is a multifactorial disease of the ocular surface caused by loss of tear film homeostasis resulting damage to the ocular surface and neurosensory abnormalities.

To compare the efficacy of local injections of two different types of steroid (betamethasone suspension versus triamcinolone acetate) in management of patients with thyroid-related upper lid retraction either isolated or associated with proptosis.

To evaluate the safety and efficacy of 1% Pro-ocular topical gel administered twice daily for 12 weeks in treatment of Dry Eye Disease

The purpose of this pilot study is to determine the feasibility of at home thermal therapy with a wireless, portable device, as an effective management of Meibomian Gland Dysfunction. This will be done by assessing patients for improvement in symptoms and ocular oil gland function after 4 weeks of a daily thermal therapy application.

This study is being conducted to evaluate the short-term (1 month) safety and effectiveness of a single TearCare procedure to treat adult patients with dry eye disease. NOTE: All sites have been selected for this study.

Introduction: Graves disease (GD) is characterized by thyrotoxicosis and goiter, arising through circulating autoantibodies that bind to and stimulate the thyroid hormone receptor (TSHR). Graves' ophthalmopathy (GO) is characterized by inflammation, expansion of the extraocular muscles and an increase in retroorbital fat. There are currently three forms of therapies offered: anti-thyroid drugs (ATD) (thionamides), radioactive iodine (RAI) and total thyroidectomy (Tx). There is currently no consensus on the treatment of Grave's disease and GO. Objective: To examine the difference in the outcome of GO in patients with moderate-to-severe GO, who receive Tx versus further ATD after suffering their first relapse of GO or in which GO stays the same following the initial decrease in ATD therapy after 6 months. Methods: This prospective randomized clinical trial with observer blinded analysis will analyze 60 patients with moderate-to-severe GO who receive Tx versus ATD without surgery. Main outcome variables include: muscle index measurements via ultrasound and thyroid antibody levels. Additional outcome variables include: CAScore/NOSPECS score, superonasal index measurements via ultrasound and quality of life score.

The proposed 3-month study is a prospective, open-label, multicentre, phase IV, proof of concept study. The study is designed to assess the effect on the quality of vision of IKERVIS® (1mg/mL ciclosporin) eye drops administered once daily in dry eye disease (DED) patients with severe keratitis, as well as its safety and efficacy.
