Assessment of macular function by focal electroretinogram and pattern electroretinogram before and after epimacular membrane surgery.
PURPOSE To evaluate macular function before and after surgical peeling of idiopathic epimacular membrane (EMM). METHODS Logarithm of the minimal angle of resolution visual acuity and results of focal (central 9 x 9 degrees) electroretinogram (fERG), pattern electroretinogram (pERG), and optical coherence tomography (OCT) assessment of macular volume were evaluated for 22 eyes of 22 patients (...
متن کاملAssessment of macular function by multifocal electroretinogram before and after macular hole surgery.
AIM To evaluate macular function before and after successful surgical closure of idiopathic macular holes using multifocal electroretinogram (ERG). METHODS 40 patients (40 eyes) with idiopathic macular holes were examined using multifocal ERG both before and after vitreous surgery. The postoperative period was from 1 to 12 months. RESULTS Preoperatively, the electrical retinal response dens...
متن کاملRod-driven focal macular electroretinogram.
PURPOSE To determine the stimulus conditions required to elicit rod-driven, focal macular electroretinograms (rod FMERGs). METHODS A blue (lambda(max)=470 nm) stimulus, 5 degrees in size, was imaged at a luminance of 1.5 cd/m(2) on different regions of the human retina. Electroretinograms (ERGs) elicited by this stimulus were recorded from the light- and dark-adapted retina of four subjects w...
متن کاملAssessment of macular function by multifocal electroretinogram in age-related macular degeneration before and after photodynamic therapy.
PURPOSE To evaluate macular function, before and after photodynamic therapy (PDT) using multifocal electroretinogram (MF-ERG), in eyes suffering from classic subfoveal choroidal neovascularization (CNV) resulting from age-related macular degeneration (ARMD). METHODS Twenty eyes of 20 patients (10 male, 10 female) with classic subfoveal CNV resulting from ARMD were studied. All received PDT wi...
متن کاملTransient macular dysfunction determined by focal macular electroretinogram.
Case report A 75-year-old man complained of a sudden and painless decrease of vision in his left eye. He had undergone surgery for an unruptured intracranial aneurysm 20 years earlier and was taking 7 mg/day of systemic prednisolone for rheumatoid arthritis. He had also had diabetic mellitus without retinopathy for 5 years. He was being followed for a left hemianopsia and normal tension glaucom...
