详细描述
Assessment in early changes in the parameters of optical coherence tomography (OCT spectral domain) in patients with subfoveal neovascularization secondary to age-related degeneration after treatment with a single intravitreal injection of Lucentis.
Age-related macular degeneration (AMD) leading cause of blindness over 50 years in developed Western countries. Its prevalence increases with age affecting about 8.5 to 27.9% of the population over 75 years. Its incidence has increased 30-40% in recent decades, in spite of eye diseases such as cataracts and glaucoma, which reach the same population group, have shown apparently reduced their records.
Although approximately 80% of patients with AMD have the neovascular form does not, the neovascular form is responsible for almost 90% of severe visual loss resulting from AMD. It creates great socioeconomic impact, becoming a public health problem.
Quantitative analysis of OCT has shown increasing clinical importance with the development of anti-VEGF therapy to evaluate the outcome of the treatment of neovascular AMD.
Relatively few studies in AMD has been proposed to examine the correlation between the morphological parameters of the OCT and BCVA in a systematic way.

研究组 & 干预措施
ranibizumab
Interventional study, prospective will be conducted in a single eye of twenty consecutive patients who will receive intravitreal ranibizumab for neovascular membrane active subfoveal choroidal active due to AMD and visual acuity of 20/40 and 20/320.
To establish the presence of active neovascularization evaluated the presence of leakage seen on fluorescein angiography and fluid, as seen in optical coherence tomography (OCT), located both intra and subretinal, or below the retinal pigment epithelium.
Treatment with ranibizumab will be offered after extensive Discussing the pathogenesis of AMD, the treatment alternatives, as well as the possible risks of treatment with ranibizumab. Term of consent shall be obtained prior to treatment.
干预措施: ranibizumab (Biological)
