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 ...

Phase N/A

The Effect of A2A Adrenoceptor Stimulation on the Diameter of Retinal Arterioles During Hypoxia in Vivo

Background Occlusion of the retinal vessels leading to retinal ischaemia and hypoxia is an important element in the pathophysiology of the major vision threatening diseases in the Western World. The hypoxic areas release vasodilating factors that induce vasodilatation in adjacent retinal areas in order to increase blood flow and retinal ...

Phase

Adjuvant Chemotherapy for High-risk Retinoblastoma After Enucleation

This study will be a phase open label interventional case series. Patients with Stage I enucleated retinoblastoma will be randomized to receive chemotherapy(CEV) of 3 cycles or 6 cycles on a monthly basis. Patients will be followed for 24 months.

Phase

Identification of New Genes Implicated in Rare Neurosensory Diseases by Whole Exome Sequencing

Next Generation Sequencing (NGS) strategy is a powerful tool to identify genes implicated in very rare diseases for which the previous genetic explorations remain negative to date. The aim of this project is based on groups of patients with original clinical phenotypes including neurosensory impairment without genetic cause identified to ...

Phase N/A

Characteristic Analysis of Retinopathy Associated With High Doses of Interferon -2b Therapy

Patients with melanomas of the skin whose tumors have been resected completely were collected. The detailed ocular examinations including intraocular pressure, slit lamp microscope, indirect ophthalmoscope and color fundus photography were done before the induction therapy, 2 weeks after the induction therapy, after the whole course of induction therapy and ...

Phase N/A

Evaluate the Quality of Life of Patients With AMD

Age-related macular degeneration (AMD) is a major cause of deep visual acuity loss. Because of progressive deterioration of the macula, patients with AMD complain about progressive visual problems that can impair their quality of life in the physical, mental and social domains. The principal objective principal of this study is ...

Phase N/A

Microalbuminuria as a Cardiovascular Risk Factor (PRECISED Substudy)

A hypothesis free approach by using proteomic/metabolomic analyses in the urine samples of selected populations seems an appropriate approach by which to explore this issue. In addition, a driven hypothesis in the same groups of patients based on a sensitive marker of kidney injury also seems appropriate. Urinary levels of ...

Phase N/A

Association of Previously Verified Gene Polymorphisms With AMD in Turkish Population

Age-related macular degeneration (AMD) remains as the most important cause of severe visual impairment of elderly people in developed countries. It is one of the best-characterized complex trait diseases. Multiple genetic and environmental factors play a role in the pathogenesis. A number of different biological pathways and related gene polymorphisms ...

Phase N/A

Antiacne Medications Pseudotumor Cerebri

Measurement of retinal nerve fibre layer using optical coherence tomography over a period of 6 to 9 months depending on exact antiacne medication.

Phase

An Open Label-study to Compare the Efficacy of Aflibercept Monotherapy for Polypoidal Choroidal Vasculopathy Using a Modified Intensive Treat and Extend Regime to a Fixed Dosing Regimen

Age related macular degeneration (AMD) is one of the leading causes of blindness worldwide. In its exudative or wet form, choroidal neovascularization (CNV) causes an exudative maculopathy resulting in sudden loss of vision with severe effects on patients' quality of life.1,2 Intra vitreal injections of anti-vascular endothelial growth factor agents ...
