Active clinical trials for "Eye Diseases"

Orthokeratology(OK) is currently one of the effective methods for treating myopia, reshaping the corneal epithelium to change refractive power. Due to its contact with the ocular surface, long-term wearing could lead to symptoms and signs of dry eye disease(DED) , as well as changes in tear film stability. This prospective study randomly divided 300 children and adolescents with myopia into OK group and spectacles group, with a follow-up of 12 months. At baseline, 1, 3, 6, and 12 months, non-invasive tear breakup time (NIBUT), ocular surface disease index (OSDI) and visual analogue score (VAS) score, tear meniscus height (TMH), conjunctival hyperemia (RS score) and meibomian gland (MG) scores, tear MMP-9 concentration, and point-of-care Lymphotoxin alpha (LTA) test.

The goal of this interventional investigation is to compare BUFY01 with SVS20 in the treatment of patients with dry eye disease. The main questions it aims to answer are: Is BUFY01 non-inferior to SVS20 in terms of signs of DED? Is BUFY01 non-inferior to SVS20 in terms of symptoms of DED? Participants will be asked to: Visit the trial site at 4 different timepoints Use the allocated study treatment everyday until the end of the study (during 3 months) Be examined by the investigator Complete several questionnaires Return unused study treatment. Researchers will compare BUFY01 to SVS20 to see if both study treatments provide similar effects on signs and symptoms of the disease, together with comparable safety.

Ocular surface photography is significantly limited in standardization and reproducibility. This reduces its applicability for clinical monitoring of acute or chronic disease. The innovative lens and illumination design of the CDL system aims to yield standardized high resolution photographs of the cornea and conjunctiva as required for clinical documentation, posing a significant clinical benefit of health care providers in the field of ophthalmology. Primary objectives: The primary objective of this study is to test the safety and feasibility of the CDL imaging system in a clinical routine setting. This will include the comparison of subjective contrast sensitivity testing post imaging, and the measurement of examination duration per imaging session, and the comparison of image lightness in mesopic versus photopic imaging. Secondary objectives: The secondary objective of this study is to compare the image quality of the device and repeatability of lateral resolution, dynamic range, hue, saturation, lightness, and image position between colour photographs from a state-of the art slit lamp camera and the CDL system. This is a monocentric, prospective, observational study. Patients with ocular surface disease of variable aetiology routinely assigned to ocular surface photography, following informed consent, will be imaged using state-of-the-art colour photography and the CDL imaging system. Pictures of each patient will be taken under several standardized conditions with both methods, subsequently analysed and compared by a Medical Image Processing Specialist.

Graves' orbitopathy (GO) is an disfiguring and disabling autoimmune condition. Sight-threatening GO is an most severe form and occurs in about 5% of patients with Graves' disease. It can cause blurred vision, color vision and vision function damage, and affects the quality of life. The goal of this retrospective cohort study is to propose a customized orbital decompression algorithm for patients with sight-threatening Graves'ophthalmopathy and to explore the therapeutic effect of customized orbital decompression in sight-threatening patients.

This is a 2-cohort (observational and treatment cohort) extension study for participants completing feeder studies (IMVT-1401-3201 or IMVT-1401-3202). The observational cohort will assess the durability of proptosis response of feeder studies off treatment. The treatment cohort will evaluate the efficacy of batoclimab as assessed by proptosis responder rate.

The purpose of this study is to characterize the natural history through temporal systemic evaluation of subjects identified with PRPF31 mutation-associated retinal dystrophy, also called retinitis pigmentosa type 11, or RP11. Assessments will be completed to measure and evaluate structural and functional visual changes including those impacting patient quality of life associated with this inherited retinal condition and observing how these changes evolve over time.

Safety and Efficacy of Medications for Migraine in Patients with Dry Eye Disease or Asthenopia

The goal of this interventional investigation is to compare BUFY02 with TRB02 in the treatment of patients with dry eye disease. The main questions it aims to answer are: Is BUFY02 non-inferior to TRB02 in terms of signs of DED? Is BUFY02 non-inferior to TRB02 in terms of symptoms of DED? Participants will be asked to: Visit the trial site at 4 different timepoints Use the allocated study treatment everyday until the end of the study (during 3 months) Be examined by the investigator Complete several questionnaires Return unused study treatment. Researchers will compare BUFY02 to TRB02 to see if both study treatments provide similar effects on signs and symptoms of the disease, together with comparable safety.

Gestational diabetes mellitus is associated with abnormal blood sugar levels throughout pregnancy in women without prior diabetes. Many studies have been conducted on the relationship between diabetes and oxidative stress. In this study, it was aimed to investigate the presence of fundus findings in patients with gestational diabetes and/or impaired blood sugar based on the results of previous studies and to simultaneously investigate the thiol-disulfide homeostasis in the tears of the patients.There was no previous study in the literature on thiol disulfide homeostasis in tears in gestational diabetic patients.
