Filter by:The objective is to find if there is a relationship between the Fractal Dimension, the gap, vascular density (VD), the surface, the span ratio and the status of the choroidal neovessels to adjust the interval between 2 intravitreal injections nor on the qualitative aspect of Optical Coherence Structural Tomography but also on quantified quantitative and objective values.
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.
This was a multicenter, open label study that is designed to evaluate the safety of brolucizumab 6 mg in a prefilled syringe in subjects with neovascular age related macular degeneration and to support collection of observations of the prefilled syringe use for intravitreal injection.
Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.
It has been shown that reactions of human retinal photoreceptors to a light stimulus can be measured with custom-made, research prototype optical coherence tomography (OCT) systems. This can be used as a biomarker for the function of the photoreceptors. Due to the high technical demands on the system, however, the technique is currently not available for clinical purposes. In this pilot study a protocol to measure changes in retinal photoreceptor layer thickness before and after light stimulation shall be developed based on a commercial OCT system and newly developed algorithms. Other variables, such as circadian processes shall be investigated as well. After measurements in healthy volunteers, the protocol is planned to be applied in patients with primary open angle glaucoma (POAG) and age-related macular degeneration (AMD) to test for feasibility of the method in these patient groups.
In patients with AMD a deterioration of the antioxidant mechanisms of the retina is observed and therefore an increase in the production of free radicals responsible for tissue damage. The Age-Related Eye Disease Study (AREDS) found that the intake of antioxidants reduces the risk of progression of the disease to an advanced stage (choroidal neovascularization or geographic atrophy ) and reduces the loss of visual acuity. In this study the investigators want to analyze the functional retinal changes (mfERG) of the macular region, in patients with dry age-related macular degeneration, after the use for 6 months of an oral supplementation based on Ganoderma lucidum (Reishi), Calendula Officinalis, Lutepure-Marigold ( 5% Lutein and 1% Zeaxanthin) Blueberry, Rutin, Alpha-lipoic acid, Bromelain, NAC, Vtiamine C, B9, B12, D3, Selenium, Zinc and Copper.
A prospective randomized trial, to evaluate post-injection comfort measures comparing topical NSAID (nepafenac 0.3% suspension) and patching.
The purpose of this study is to be able to describe optical coherence angiography (OCTA) patterns of disease activity and quiescence in eyes that have received treatment. The target population group is patients that have neovascular age-related macular degeneration and have had treatment with aflibercept for this condition. This is a single-site study and does not involve any masking or treatment allocation.
An observational study to evaluate the natural progression of dry AMD in genetically defined subjects
This is a prospective, randomised, multi-site clinical trial testing the non-inferiority of community optometry follow-up of participants with QnAMD over 12 months
