Filter by:The purpose of this study is to evaluate the safety and tolerability of QR-421a administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.
Although evidence have clearly proved that intravitreal injection of vascular endothelial growth factor antagonists prevents vision loss and may even improve visual acuity in patients with neovascular AMD, a significant percentage of patients continue to lose visual acuity. Moreover, monthly intravitreal injections represent a burden for society as well as the caregiver. Combination therapy with either topical 0.1% pranoprofen or nutraceutical support with AREDS2 formula plus omega-3 might act synergistically with intravitreal injection, offering valuable therapeutic support to aflibercept injections in patients requiring long-term treatment.
This study is a prospective comparative study to gather pilot agreement and precision data in normal subjects, subjects with glaucoma, and subjects with retinal disease.
A prospective natural history study with systematic assessments and uniform follow-up to provide a high-quality dataset for assisting in the design of future clinical treatment trials involving patients with CEP290-related retinal degeneration caused by the common intron 26 mutation.
The Retinopathy of Prematurity (ROP) is one of the leading causes of blindness on the pediatric age worldwide. This pathology is characterized for arrest of the normal vascular and neuronal retina that because of pathological compensatory mechanisms results in proliferation of vascular tissue that grow in the limit between the vascular retina and the avascular retina. The ET-ROP group classified the ROP by those who need treatment immediately or those who doesn't need treatment, The classification is the following Type 1 ROP-->ROP zone I any stage with plus, zone I stage 3 without plus, zone II stage 2 y 3 with plus Type 2 ROP --> Zone 1, Stage 2 or 3 without plus, and Zone II, stage 3 without plus. The treatment is begun on patient with type 1 ROP and type 2 ROP is maintained in observation.
This study is a longer-term follow-up study for patients who have been administered AAV2/5-OPTIRPE65 in the Phase I/II, open label, non-randomised, two-centre, dose escalation trial in adults and children with retinal dystrophy associated with defects in RPE65.
The objectives of this study include using the new technology of SS-OCT (swept source optical coherence tomography) to evaluate morphological abnormalities of the vitreous, retina and choroid and to assess the repeatability of retinal and choroidal thickness measurements in retinal disease using SS-OCT. A secondary objective is to use the new imaging modality of adaptive optics to directly visualize photoreceptor mosaics and microvasculature in eyes with retinal and choroidal disease.
Ophthalmology is among the most technology driven of all medical specialties, with advanced medical imaging devices - and specialised computer software - increasingly adopted for routine clinical use. While many such devices are capable of completing specific tasks, lack of "usability" prevents their widespread adoption (i.e., such devices are not easy to learn and remember, or are not efficient or subjectively pleasing to use). Moreover, devices that are difficult to use expose patients to clinical risk as a result of human error during usage. With the introduction of a new medical technology, it is essential, therefore, to have a deep understanding of patients, what they need, what they value, their abilities, and also their limitations. Human factor and usability testing, also known as "human factor engineering", deals with the formal study of people's interaction with their environment (in this case, the binocular optical coherence tomography (OCT) device). Structured, patient-centred, usability testing is essential to the design, clinical validation, regulatory approval, and widespread implementation, of all new medical devices. This is particularly the case for a putative binocular OCT system - a device intended for automated use in visually impaired, often elderly, populations. Although the binocular OCT is already at an advanced stage of hardware development, the EASE study will facilitate an iterative process of operating software and workflow modifications to optimize the device for use in these populations.
Comparison of OCTA to conventional imaging modalities for the diagnosis of eye diseases
The purpose of this study in to compare the efficacy of treatment of diabetic macular edema (DME) using Ranibizumab (Lucenti®), Aflibercept (Eylea®) and Aflibercept (Eylea®) plus Ranibizumab (Lucentis®). It is a randomized clinical trial that will evaluate the efficacy of the combination of two substances currently used in the treatment of DME. Will be allocated in different four groups randomly pacients who receive treatment with intravitreal injections of ranibizumab, aflibercept or a combination of aflibercept and ranibizumab.
