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

Advancing Understanding of Transportation Options

The investigators will use a multi-site, two-armed randomized controlled trial of older drivers (n=300; 70 years) from clinical settings, and one family member each (n=up to 300), with longitudinal follow-up. Study goals are to test how much the DDA improves outcomes and identify who benefits most from the DDA. Evaluation ...

Phase N/A

Global Atrophie Biomarker Evaluation Study (GABiE)

To investigate the use of microperimetry and SS-OCT in assessing the natural changes of retinal sensitivity and anatomy in the perilesional zone of geographic atrophy areas in patients with dry age-related macular degeneration.

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

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. ...

Retinal Imaging Using NOTAL-OCT V3.0

4.5.1 SCREENING VISIT: For patients eligible to participate in the study, the following procedure will be done in the screening visit: Patient will sign the IC (Informed Consent) form Test the eligible eye(s) of the patient will be tested The following demographic and clinical data will be collected for each ...

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

Vitamin A Palmitate Supplementation in Patients With Reticular Pseudodrusen (RPD) and Delayed Dark Adaptation

Objective: The objective of this study is to investigate the potential efficacy of vitamin A palmitate in improving dark adaptation in participants with reticular pseudodrusen (RPD) and abnormal dark adaptation. Study Population: Ten participants will be initially accrued, however, up to twenty participants with RPD who meet the eligibility criteria ...
