Measurement of Optic Nerve Sheath Diameter in Children Without the Increased Intracranial Pressure

The purpose of this study is to measurement of optic nerve sheath diameter in children without intracranial pressure increase and determine the average optic nerve sheath diameters for healthy children. For that, between 4 and 18 years old children will be selected. After taking of measurements, following parameters will be ...

Phase N/A

Ultra-wide Fluorescein Angiography in Patients With Central Retinal Vein Occlusion Treated by Afilbercept

The pathophysiology of Central Retinal Vein Occlusion (CRVO) is incompletely understood, but a significant slow-down in blood flow, caused by various predisposing factors, results in the release of VEGF, leading to the breakdown of the blood-retinal-barrier and finally to macular edema. The level of VEGF has been also correlated with ...

Phase N/A

DETECT and Retinal Outcomes in Hypertension

Four groups will be evaluated for possible impact of blood pressure on cognitive performance and retinal damage.

Phase N/A

Metformin for the Minimization of Geographic Atrophy Progression in Patients With AMD

This is a phase II, single-blind, randomized, evaluation of the safety and efficacy of metformin use to decrease geographic atrophy (GA) progression in non-diabetic patients with dry Age-related Macular Degeneration (AMD). Approximately 100 study subjects throughout four separate study sites will be randomized in a 1:1 ratio to the treatment ...

Telescope Exchange Study

VisionCare's Implantable Miniature Telescope (IMT, intraocular telescope or telescope) is indicated for monocular implantation to improve vision in eyes of patients at least 65 years of age with severe to profound vision impairment caused by bilateral central scotomas associated with end-stage age-related macular degeneration (AMD). Patients with end-stage AMD who ...

Phase N/A

The Effects of Regular Eye-training With a Mobile Device on Adult Patients With AMD

In the presented study a training-therapy in patients with dry AMD war evaluated. The main focus was on remote visibility and thus better handling of daily activities. Therapy with high-contrast administration is used for amblyopia in childhood. Furthermore, simulation therapy is used in hemianopsia in the adult age, in which ...
