Filter by:Long-term observational study to assess the safety, efficacy and quality of life of patients with neovascular age-related macular degeneration (AMD) under Macugen treatment.
Background: Biofeedback techniques have demonstrated their uselfulness in the treatment of maculopathies. We wanted to evaluate the efficacy of visual rehabilitation by means of two different types of biofeedback techniques in patients with age related macular degeneration (AMD). Methods: 30 patients bilaterally affected by AMD were enrolled with a mean age of 76,38±8,77 yrs. Patients were randomly divided in two groups: Group A was treated with an acoustic biofeedback, Group B with luminous biofeedback of a black and white checkerboard flickering during the examination. All patients underwent a complete ophthalmological examination. Rehabilitation consisted in 12 training sessions of 10 minutes for each eye performed once a week for both groups. Statistical analysis was performed using t- test. P values less than 0.05 were considered statistically significant. Results: Group A: visual acuity at the end of rehabilitation had improved, but this result was not statistically significant (p=0.054), reading speed showed a significant statistical improvement (p=0.031), as well as the fixation stability (p=0.0023) and single point mean retinal sensitivity value (p=0.044). Group B: visual acuity improvement at the end of rehabilitation was statistically significant (p=0.048), reading speed showed a statistically significant improvement (p=0.024), as well as fixation stability (p=0.0012) and mean single point retinal sensitivity value (p=0.027). Final results for both groups were compared and patients in group B showed results which were statistically more significant. Conclusion: A contrast rich flickering biofeedback stimulus showed a statistically significant improvement in training the patients to modify their preferred retinal locus (PRL) in comparison to acoustic biofeedback. It is possible that increased involvement of the various retinal cell populations with visual stimuli create more efficient ganglion cell response that better utilize the residual retinal function.
This study is to investigate whether there is an association of the LOC387715/HTRA1 and vascular endothelial growth factor polymorphism with response to treatment with intravitreal ranibizumab injections for patients with polypoidal choroidal vasculopathy.
This study is to investigate whether there is an association of the LOC387715/HTRA1 variants with response to treatment with combined photodynamic therapy and intravitreal bevacizumab for patients with polypoidal choroidal vasculopathy.
The main purpose of this study to evaluate the safety and tolerability of CNTO 2476 administered subretinally (beneath the retina) using the iTrack Model 275 micro catheter in patients with visual acuity (acuteness or clearness of vision) impairment associated with the geographic atrophy (GA: partial or complete wasting away of retinal layer below the retina) manifestation of age-related macular degeneration (AMD: medical condition which usually affects older adults and results in a loss of vision in the center of the visual field [the macula] because of damage to the retina).
The purpose of this study is to evaluate the safety and clinical feasibility of the IRay System for the treatment of wet age-related macular degeneration (AMD).
This study will evaluate the preliminary safety and efficacy of PDS 1.0 in patients with neovascular AMD.
This study will evaluate the safety and preliminary effectiveness of PDS 1.0 in patients with neovascular AMD.
The primary purpose of this study is to assess the safety & tolerability of an investigational drug 20089 TA (6.9 mg or 13.8 mg) when used adjunctively with Lucentis 0.5 mg in subjects with sub-foveal neovascular AMD.
The purpose of this study is to determine a possible implication of CD21, CD35 and CD55 in the pathogenesis of age-related macular degeneration. The aim is to asses a difference in expression rates of these factors on AMD-patients and a healthy control group.
