Fourier Transformed Infrared Spectroscopy in Macular Surgery

Purpose of the present study is to analyse components of ERM and ILM, giving hints for the origin of cells producing ERM. In contrast to electron microscopy, FTIR spectroscopy does not need any chemical fixation of the membranes and therefore structure of components of ERM and ILM are not changed ...

Phase N/A

Prevention of Macular Edema In Patients With Diabetic Retinopathy Undergoing Cataract Surgery

Diabetic retinopathy patients who are at risk of developing macular edema (defined as 30 % increase from pre-operative baseline in central subfield macular thickness) within 90 days following cataract surgery. Diabetic patients are defined as those who have either Type 1 or Type 2 diabetes. The patients must have either ...

Phase

Treatment of Diabetic Macular Edema With Aflibercept in Subjects Previously Treated With Ranibizumab or Bevacizumab

This study is an investigator initiated interventional study for subjects with diabetic macular edema that have been previously treated with bevacizumab or ranibizumab. Intravitreal aflibercept 2mg will be given until OCT (ocular coherence tomography) demonstrates an absence of fluid. Continued intravitreal aflibercept 2mg will then take place every 2 months ...

Phase

Perifoveal Vascular Network Assessed by OCT-Angiography in Type I Diabetes Mellitus

Diabetic retinopathy (DR) is the leading cause of blindness in type 1 Diabetes Mellitus (DM) patients, as a consequence of impaired blood flow in the retina. Optical coherence tomography angiography (OCT-A) is a newly developed, non-invasive, retinal imaging technique that allows detection of perfused and non perfused areas of the ...

Phase N/A

IAI Versus Sham as Prophylaxis Against Conversion to Neovascular AMD

128 subjects will be enrolled in the trial and randomized in a 1:1 ratio to receive either IAI every three months for 24 months or sham injections. Enrollment will be stratified in order to ensure a balance between the two treatment groups for subjects who were diagnosed with exudative AMD ...

Phase

Retina Microvascular Remodeling and Cognitive Function In Hypertension

Our project stands on physiopathological and cognitive angles, and is mainly based on the major role of large and small arteries elasticity on cognitive aging. It will benefit from the recent innovative accurate and non invasive techniques such as MRI for central large arteries and adaptative optics for retina arterioles ...

Phase N/A

Thermal Screening for Early Diabetic Peripheral Neuropathy (DPN)

This study focuses on further development and testing of a microvascular functional imaging system, a computer-based system for screening thermal video images, designed to detect biomarkers of diabetic peripheral neuropathy (DPN). Additionally, severity levels of diabetic retinopathy (DR) will be compared with those of DPN. All participants in this study ...

Phase N/A

SPT Screening in Irradiated Hereditary Retinoblastoma Survivors

Rationale: Hereditary retinoblastoma survivors have an increased risk to develop second primary tumors (SPT) at a later age (with the highest risk in their teens), especially when they have been irradiated for retinoblastoma. The investigators hypothesize that regular screening with magnetic resonance imaging (MRI) could lead to early detection of ...

Phase N/A

Comparison of Diabetes Retinopathy Among Type 2 Diabetic Patients Treated With Different Regimens

Diabetic retinopathy (DR) is an important cause of blindness, and its development of an irreversible process. DR is not only the overall progress and the level of blood sugar, and blood glucose fluctuations more closely, is the key to a smooth hypoglycemic delay DR progression.Diabetes control and complication trail(DCCT) study ...

Phase N/A

Ocular Imaging Study Using Advanced OCT

The purpose of this study is to evaluate this AngioScan angiography software on patients with various retinal vascular disorders. The advanced OCT instrument is an FDA approved clinically used camera, but the AngioScan angiography software is not FDA approved. Investigators would like to know if this imaging device and software ...
