Pro-permeability and Pro-fibrosis Factors in the Aqueous of Patients With Retinal Diseases

The primary purpose of this study is to determine the correlation of pro-permeability and pro-fibrosis factor levels and downstream receptor/signaling molecule activation with disease activity in patients with macular edema or fibrosis secondary to any underlying disease. 120 patients will be enrolled from both the clinic and OR, with the ...

Phase N/A

Effect of Vitrectomy on the Evolution of Refractory Diabetic Macular Edema

In case both eyes present refractory diabetic macular edema (DME) and are eligible, the eye with the worst DME will be included and randomized.

Phase N/A

Screening for Hereditary Transthyretin Related Amyloidosis - an Internationales Multicentre Epidemiological Protocol (TRAM)

Hereditary TransThyRetin Amyloidosis (hATTR) is a slowly progressive condition, that is transmitted as an autosomal dominant trait and is characterized by abnormal extracellular deposits of fibrillar, misfolded proteins (amyloid fibrils) in the body. Amyloid fibrils can be deposited in different body compartments, such as the nerves, heart, gastrointestinal tract, kidneys ...

Phase N/A

Determining Whether Multiple Anesthesia Exposures Affect Cognitive Function for Retinoblastoma Patients

The purpose of this study is to see if there is a difference between the development of the brain (neurodevelopment) in children who have been treated for retinoblastoma with multiple anesthetic exposures, compared with brain development in children who have never had anesthesia.

Phase N/A

Adaptive Optics for Ophthalmic Technologies

Adaptive optics (AO) is an optical technique that corrects the natural aberrations (optical imperfections) of the eye. Since it was first described in 1997, it has been used successfully to enhance the visualization of retinal tissue, in particular, the human photoreceptor mosaic. Previous studies using AO in the human eye ...

Phase N/A

National Eye Institute Biorepository for Retinal Diseases

This study establishes a clinical database and biospecimen repository for the identification of novel factors relevant to the pathogenesis, progression, and response to treatment of a variety of retinal conditions, particularly age-related macular degeneration and diabetic retinopathy, and their associated systemic correlates of disease. Objectives: This study provides for standardized ...

Phase N/A

Improving Vision in Adults With Macular Degeneration

This study will be carried out in Ontario, Canada (University of Waterloo) and Hong Kong (The Hong Kong Polytechnic University). There are two conditions: Active brain stimulation and sham/placebo brain stimulation. This study uses a within-subjects design, such that all participants will take part in both conditions on separate sessions. ...

Phase N/A

Soluble Cluster of Differentiation 160 (sCD160) in Sera and Intra-ocular Fluids: Association With Ischaemic Retinopathies

120 patients enrolled for ophthalmic surgery (cataract or posterior segment surgery (epiretinal membrane, macular hole, vitrectomy)) will be recruited in the Department of Ophthalmology, Robert Debr Hospital, Reims, France. Each patient will benefit a complete ophthalmologic examination, and either an aqueous sampling (cataract) or a vitreous sampling (posterior segment) along ...

Phase N/A

Medico-economic Comparison Between Treatment With Panretinal Photocoagulation by Laser in 1 Session Versus 4 Sessions in Diabetic Retinopathy

Despite the fact that the efficacy of a single session of multispot laser has been demonstrated in the treatment of patients with diabetic retinopathy as compared with four sessions of single-spot laser, the management of panretinal photocoagulation in the different healthcare establishments in France has remained unchanged notably because there ...

Phase N/A

Comparison of Complement Factors and Genetic Polymorphisms of AMD Between Patients With Systemic Lupus Erythematosus (SLE) With and Without Retinal "Pseudo-drusen-like" Deposits: Case-control Study (PL-AMD)

The rationale of this research is to determine if patients with lupus and presenting retinal "pseudo-drusen-like" deposits have genetic and complement-related similarities with AMD patients. Based on the results obtained, this study could lead to future research that could better target the treatment of patients with lupus or patients with ...
