Filter by:This open-label, Phase IV prospective, observational study will evaluate patients, who have been diagnosed with Neovascular Age-Related Macular Degeneration and have previously received either a standard intravitreal injection of ranibizumab or aflibercept, in order to get and compare information regarding post-injection inflammatory (irritation in the eye)2-3 days post-injection. Additionally, patients will be evaluated for visual acuity and pain 2-3 days post-injection. THIS IS AN OBSERVATION STUDY AND NOT AN INTERVENTIONAL STUDY AS TO ENTER THIS STUDY SUBJECTS WILL HAVE HAD TO RECEIVED EITHER RANIBIZUMAB 0.5 MG OR AFIBERCEPT 2MG PRIOR TO ENTERING THE STUDY AND SIGNING CONSENT. THIS STUDY IS TO OBSERVE THE SUBJECT POST-INJECTION RECEIVED BEFORE ENTERING THIS STUDY.
The need for low vision services (LVS) will increase exponentially over the coming years due to the anticipated and exponential growth in the ageing population in Singapore and a rise in chronic non-communicable eye diseases. Finding the best evidenced-based management for chronic eye diseases contributing to low vision (LV) is therefore crucial. Improving patient responsibility is the key to managing LV effectively.1 This means achieving optimum self management (SM).2 However, there are currently no LV SM programs in Singapore and none has been evaluated using a randomized controlled trial (RCT) design, the gold standard methods to evaluate health interventions. The aims of this study are to assess the effectiveness of the 'Living Successfully with Low Vision (LSLV)' program in improving quality of life (QoL) in 160 elderly people with LV attending the Singapore National Eye Centre (SNEC) LV clinic. Of these, 80 will be randomly allocated to receive the LSLV 4-week SM program while the remaining 80 will receive the usual care. Comparisons will be made to determine the efficacy of the LSLV program. QoL, self-efficacy, emotional well being, and vision-specific distress will be assessed 2 weeks after training, and at six months and 12 months post intervention. This study will be the first evidenced-based RCT investigating the effectiveness of a novel vision-specific self-management strategy to improve QoL. It will also adopt a longitudinal design where the effectiveness of these interventions will be evaluated at 12 months-the first follow-up assessment of that duration at both national and international levels. Furthermore this will be the first study to characterize and profile the patients where the effect of the program did not demonstrate an improvement in both primary and secondary outcomes six months after its completion. The future clinical implications of this study include the potential to implement a successful model of LV rehabilitation in other tertiary centres around the country.
Studying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective of this study is to obtain and analyze high-resolution images of the retina, in particular by imaging the cone photoreceptor mosaic, the retinal vasculature and other retinal layers. The study design will involve case-control studies, where cases are followed over time. Subjects age 7 and older may be invited to participate. The main research procedure involves retinal imaging with the AOSLO. The primary endpoint is the observation of differences in retinal images between subjects with and without retinal diseases. These changes will be quantified by examining the cell density, size, spacing and regularity of the cone photoreceptor mosaic, as well as examining the differences between other retinal layers.
Phase 1 trial of retinal pigment epithelium replacement in subjects with wet age-related macular degeneration in whom there is rapidly progressing vision loss
Genetic factors of an individual patient may have an impact on Ranibizumab (Lucentis) treatment outcome in patients with Wet Age-Related Macular Degeneration (AMD).
The main purpose of this study is to investigate the association between VEGF gene polymorphism and the response to intravitreal drugs in neovascular age-related macular degeneration. This is a retrospective review of patients treated between 2008 and 2012 at the Institute of Vision, in Belo Horizonte, Brazil.
Patients who will be scheduled for intravitreal injection of Ranibizumab or Bevacizumab will be recruited in this prospective self-controlled trial. Fundus photography will carried out at baseline immediately before injection and at 3, 7 days and 30 days after the first injection. Using image analysis software, measurements summarized as the central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE). Null Hypothesis: There is no significant difference between arteriolar/venular diameter before and after injection of intravitreal ranibizumab/bevacizumab in the treated and untreated eye
Treatment naive patients with subfoveal nAMD initially treated monthly with intravitreal anti-VEGF and subsequently PRN, will be included in this study. Patients will be investigated for the first 2 years monthly and subsequently according to disease activity but at least every two months. Patients will be examined with 4m BCVA ETDRS distance visual acuity, reading acuity measured by Radner-Reading-Charts, contrast sensitivity by Pelli-Robson score, microperimetry and HD-OCT.
The investigators think that there is a connection between the use of plaquenil and the prevention of Age related macular degeneration (AMD). The investigators believe that the use of plaquenil makes bruch's membrane thicker, thereby preventing Chroidal Neovascularization (CNV) growth.
The purpose of this study is to confirm the clinical and economic benefits of IRay treatment with respect to the number of anti-VEGF injections and frequency of visits during the first year after treatment for patients with wet Age-related Macular Degeneration (AMD).
