Reduced amplitude and delayed latency in foveal response of multifocal electroretinogram in early age related macular degeneration.
AIM To explore the use of multifocal electroretinograms (MERG) in detecting early changes in age related macular degeneration (AMD). METHOD 15 pre-AMD or early AMD eyes showing retinal drusen or irregular fundus pigmentation with window defects by fluorescein angiography (FA) and mildly decreased visual acuity were examined and compared with their asymptomatic fellow eyes. 20 age matched norm...
متن کاملEarly multifocal electroretinogram findings during intravitreal ranibizumab treatment for neovascular age-related macular degeneration.
PURPOSE To evaluate changes in the multifocal electroretinogram (mfERG) in patients with neovascular age-related macular degeneration (nAMD) undergoing ranibizumab treatment. METHODS This was an observational, longitudinal, prospective study. Treatment-naive patients with nAMD who met the inclusion and exclusion criteria underwent a course of monthly injections of ranibizumab over 3 months. A...
متن کاملMultifocal Electroretinogram Findings after Intravitreal Bevacizumab Injection in Choroidal Neovascularization of Age-Related Macular Degeneration
PURPOSE To evaluate the changes in multifocal electroretinogram (mfERG) and optical coherence tomography (OCT) after intravitreal bevacizumab injection in the treatment of age-related macular degeneration (AMD). METHODS Twenty-one eyes with choroidal neovascularization secondary to AMD were studied before and after intravitreal bevacizumab injection for best corrected visual acuity (BCVA), OC...
متن کاملCone-mediated multifocal electroretinogram in age-related macular degeneration: progression over a long-term follow-up.
OBJECTIVE To evaluate the progression of change in the cone-driven multifocal electroretinogram (mfERG) responses in patients previously identified as having high-risk, soft drusen 63 mum or greater. METHODS Seventeen eyes of 14 patients were reevaluated after 28 to 41 months. Fundus changes were graded depending on drusen size and extent. Each of the 103 mfERG responses was analyzed and comp...
متن کاملCentral retinal function as measured by the multifocal electroretinogram and flicker perimetry in early age-related macular degeneration.
PURPOSE To determine the retinal function in early age-related macular degeneration (AMD) assessed by the multifocal electroretinogram (mfERG) and flicker perimetry and to seek a relationship between local objective mfERG parameters and subjective flicker perimetry thresholds. METHODS mfERG and flicker perimetry were performed in 15 patients (15 eyes) with early AMD and 14 controls (14 eyes) ...
