Filter by:This study is to characterize mitochondrial DNA (mtDNA) populations in adults with eye injuries and eye diseases. The eye exam is often hindered by the clouding of tissues involved in injury or disease. This protocol examines the use of mtDNA populations as indicators of developing inflammation and resolution of injury. This may be used to provide proactive treatment or define appropriate treatment needs beyond the indications of an ophthalmological exam.
The purpose of this study is to assess the Safety and Efficacy of IONIS-FB-Lrx for up to 120 patients with Geographic Atrophy secondary to Age Related Macular Degeneration
120 Patients with visual acuity <6/12 will be randomized to receive either usual care or participate in a 6-week, 2 hour 'Living with Vision Loss' program led by trained leaders. We hypothesize that a structured self-management low-vision rehabilitation program provides a greater improvement in participation in daily activities, and improves quality of life in vision-impaired people compared to the provision of the usual low vision rehabilitation services. We also plan to document barriers that prevent patients with low vision (visual acuity <6/12) from participating in self-management course.
From 3 large patient databases, patients diagnosed with AMD who have never taken levodopa(L-DOPA) containing medications have a mean age of diagnosis at 71 years. Patients who have been treated with L-DOPA containing medications have a mean age of diagnosis of AMD at 79 years. L-DOPA binds to GPR143 in the retinal pigment epithelium, and releases PEDF, which protects the retina and downregulates VEGF, which is the cause of neovascularization. The Investigators will evaluate the safety and tolerability of carbidopa-levodopa in patients with AMD, and measure the effects on surrogate functional biomarkers of AMD.
To evaluate the safety of 3 regimens of short-term, low-dose systemic IMT as rejection prophylaxis prior to and/or following transplant of MA09-hRPE cells.
The purpose of this study is to evaluate anatomical and functional effect of combination therapy of Squalamine Lactate Ophthalmic Solution, 0.2% administered twice daily with monthly ranibizumab intravitreal injections in patients with choroidal neovascularization due to AMD.
Age-related macular degeneration (AMD) is the leading cause of blindness in the Western World. The etiology and pathogenesis of this disease remain largely unknown. In Europe about two million people suffer from AMD. According to the Age-Related Eye Disease Study (AREDS) the disease can be classified into early, intermediate and late. Early age-related macular degeneration is characterized by the presence of small or medium-sized drusen and/or retinal pigmentary abnormalities. Intermediate age-related macular degeneration is characterized by large drusen or numerous medium-size drusen and/or geographic atrophy not extending to the center of the macula. Late age-related macular degeneration can be either atrophic with extension to the macula or neovascular. The late form of the disease is associated with a pronounced loss of visual acuity. In the recent years several studies focused on risk factors for late AMD and a recent systematic review and meta-analysis reported risk factors for AMD based on 16 studies in almost 114000 subjects. Strong and consistent associations with late AMD for found for increasing age, current cigarette smoking, previous cataract surgery, and a family history of AMD. Consistent associations between late AMD and higher body mass index, history of cardiovascular disease, hypertension and higher plasma fibrinogen were also found, but the association was weak. Inconsistent associations were found for gender, ethnicity, diabetes, iris color, history of cerebrovascular disease, serum total and HDL cholesterol and triglyceride levels. Evidence has also accumulated that other factors influence the risk for AMD. Several genetic risk factors have been identified in the last years including genes in the alternative complement pathway and the RMS2/HTRA1 region. In addition, post-hoc analysis of data from the AREDS study has indicated that reduced intake of the omega-3 free fatty acids eicosapentaenoic acid and docsahexaenoic acid are associated with the risk of late AMD thereby supporting previous population based studies. The AREDS study also revealed that reduced intake of the macular pigment lutein and zeaxanthin may be associated with late AMD, again supporting previous population-based studies. Finally, 2 small studies indicate that reduced choroidal blood flow is associated with an increased risk of developing late AMD. Less data are available for the progression of early or intermediate AMD and the associated risk factors. This is at least partially related to the problems in quantifying progression of drusen size and volume. In the recent years, however, significant efforts have been achieved in optical coherence tomography (OCT)-based methods for quantifying drusen progression and drusen volume. Polarization-sensitive OCT is the most promising of these approaches and will be used to quantify drusen area and volume in the present study.
This is a pilot study to evaluate the safety of the Model WA-NG telescope prosthesis in patients with bilateral moderate to profound central vision impairment due to end-stage age-related macular degeneration.

The objective of this study is to confirm the safety and to establish the effectiveness of low voltage external beam radiosurgery using the IRay System for the treatment of subjects with recurrent leakage secondary to neovascular Age-related Macular Degeneration (AMD) as determined by decreasing the number of Lucentis injections required during the first 12 months of the study.
