Detailed Description

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.

It is important to assess the impact that different OCT parameters have on visual acuity as early as 7 days after intravitreal injection of ranibizumab in patients with AMD to define which of these parameters correlate better with the AV and prognosis. It is also unknown which patients' perception of the effectiveness of treatment in early stage. For this evaluation, we apply the visual function questionnaire (VFQ - 25) 1 and 7 days after treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Experimental: 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.
