Active clinical trials for "Eye Diseases"

A randomized, controlled, double-masked, investigator-initiated trial to evaluate tear film quality and stability in subjects with dry eye disease using OC-01 (varenicline solution) nasal spray 0.03 mg as compared to vehicle control nasal spray.

The centre of the retina (macula) at the back of the eye contains cells that give us our central vision that we use for reading and recognising faces. These cells can be damaged by a disease called wet age-related macular degeneration (AMD), where new abnormal blood vessels grow through the macula and leak fluid. This can affect vision. In some cases, wet AMD can also cause a bleed under the macula, known as a submacular haemorrhage (SMH), which can lead to marked and persistent loss of vision in the eye. The current standard treatment for wet AMD is to give injections containing 'anti-VEGF' drugs into the eye. Anti-VEGF drugs reduce the leakage of fluid so that the macula can become dry again and sight can improve. Anti-VEGFs are also the current standard of care for SMH, mainly because there is no licensed treatment for the SMH itself (patients with SMH were excluded from most wet AMD studies). The purpose of this study therefore is to compare two treatments: Standard treatment for wet AMD (anti-VEGF injections). Standard treatment above plus surgery. This study will find out if having surgery alongside anti-VEGF injections can improve vision further over the current standard treatment of anti-VEGF injections alone.

Testing whether Bimatoprost, a topical eye drop used for glaucoma, can be used to induce periorbital fat atrophy in patients with Graves' disease

The aim of this study is to investigate the cost-effectiveness of a nurse-assisted online eye-screening in home healthcare in reducing eye complaints.

Platelet-rich plasma (PRP) is an autologous blood product rich in proteins and growth factors. Its application has been the subject of many studies in the field of ophthalmology to stimulate tissue healing and regeneration. Due to its anatomical features (lack of blood vessels), the cornea is among the most susceptible to damage structures of the eye. Therefore, the study of the impact of various regenerative therapies (autologous blood products, serums, ) on corneal lesions is important not only scientifically, but also practically for ophthalmologist. Numerous reports described the healing effect of PRP on corneal lesions.

Cystoid macular edema (CME) is a major cause of suboptimal postoperative visual acuity after cataract surgery. Topical steroidal and nonsteroidal anti-inflammatory drugs (NSAIDs) are used to prevent CME. However, noncompliance with eye drops may compromise the effectiveness of treatment. Dropless periocular drug delivery during cataract surgery may improve the outcomes and cost-effectiveness of cataract surgery, and may alleviate the burden on homecare organizations.

The Boston keratoprosthesis (KPro) is a special plastic device that is used to replace a sick cornea (transparent part of the eye, in front of the iris) in order to restore vision in patients who have failed traditional corneal transplants or have a very poor prognosis of success. Glaucoma is a chronic disease which causes optic nerve damage secondary to high pressure inside the eye and could lead to vision loss in the long term. Glaucoma is highly prevalent in patients who require a KPro and even more after their procedure. In order to decrease the intra-ocular pressure, surgeons can use multiple eyedrops. Unfortunately, following the KPro surgery, eyedrops lose their efficiency because they are less absorbed by the eye. The transscleral cyclophotocoagulation (TS-CPC) is a laser treatment used in advanced refractory glaucoma. This laser helps decrease the intra-ocular pressure and have a better control of the disease. There are different methods of laser transmission, including the continuous transmission (G-Probe) and the micro-pulsation method (Micopulse). Given the high prevalence of glaucoma in patients receiving a KPro, the investigators are studying the effect of giving the TS-CPC treatment prophylactically to patients before their Boston keratoprosthesis. Our hypothesis is that prophylactic TS-CPC will decrease glaucoma progression as well as the risks of developing glaucoma following the Boston keratoprosthesis . METHOD The investigators aim to recruit twenty (20) patients who are scheduled to receive Boston KPro. Participants will be randomized into two groups: 1) Groupe 1 will receive a prophylactic treatment of transscleral cyclophotocoagulation a G-Probe. 2) Groupe 2 will receive a prophylactic treatment of transscleral cyclophotocoagulation with a micropulse transmission (MicroPulse). The patients will receive their laser treatment by a glaucoma specialist 4 to 8 weeks before their KPro surgery. One week following their laser treatment, the participants will be examined by their glaucoma specialist. Following their KPro surgery, patients will have a follow-up at day-1, weeks 1 and 2, months 1 and 3, then every 4 to 6 months for 5 years. Additional non-invasive glaucoma tests will be performed twice during the first 3 months following the surgery and will be repeated every 4-6 months. Visual acuity results, the visual field tests and rates of post-operative complications will be compared between the different groups.

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss as people age. Studies have shown that lutein and zeaxanthin, nutrients found in green leafy vegetables and egg yolks, can help protect against AMD in older adults. These nutrients form a pigment in the retina (macular pigment) that can help protect the retina from light damage. Pistachios are rich sources of both lutein and zeaxanthin; thus, dietary intake of pistachios could serve as a beneficial food source for eye health.

This study aims to evaluate the efficacy of doxycycline treating Thyroid Associated Ophthalmopathy by multi-modal image.

This study is designed to learn more about the impact different types of stimuli, such as heat, cold and vibration, can have on ocular pain response. This is called quantitative sensory testing (QST). Most procedures being performed in this study, except the QST, are standard of care which means they are performed during the participant's routine eye examination.
