Filter by:High myopic schisis (HMF) has the clinical feature of separation between retinal layers. It is sometimes accompanied with foveal retinal detachment, macular lamellar hole, epiretinal membrane and vitreous retraction. HMF may develop to macular hole, macular detachment and will damage the visual function. Pars plana vitrectomy (PPV) is a commonly used surgery in the treatment of HMF. PPV together with internal limiting membrane (ILM) peeling and long-term gas tamponade was reported to be safe and effective. But nowadays there was no available long-term gas in our country. Also, whether ILM peeling is necessary remains controversial, Indole cyanine green (ICG)was proved to have potential toxicity to the retina and the ILM peeling has the risk of causing secondary macular hole. We propose to make a prospective nonrandomized controlled study to evaluate the safety and efficiency of using PPV alone in the treatment of HMF.
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.
This study is directed to evaluate the role of Optical Coherence Tomography Angiography (OCT-A) in the evaluation of the perifoveal vascular network in type 1 diabetic patients, and to investigate the relationship between OCT-A-derived parameters and demographic and clinical factors, as metabolic control and duration of the 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.
To validate new screening instruments for eye disease, increase eye care access in underserved communities, and provide a scientifically implemented method to set up programs for eye disease screening.
This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.
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.
This study is designed to evaluate and compare in-tissue performance of OCT scans on the new Optos P200TE, versus the predicate Optos Spectral OCT/SLO device.
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.
