Transient 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...
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 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 کاملFocal macular electroretinogram in macular edema secondary to central retinal vein occlusion.
PURPOSE To evaluate the usefulness of focal macular electroretinography (fmERG) for evaluation of macular function in eyes with central retinal vein occlusion (CRVO). METHODS fmERG recordings were made prospectively in 24 patients with unilateral CRVO. The amplitudes and latencies of the a-wave, b-wave, and photopic negative response (PhNR) were compared with other biological parameters, incl...
متن کاملFocal macular electroretinogram in X-linked congenital retinoschisis.
PURPOSE To study macular function of X-linked congenital retinoschisis (CRS) by focal macular electroretinogram (MERG). METHODS MERGs were recorded with 5 degrees, 10 degrees, and 15 degrees spots in 20 patients with CRS. Seventeen patients showed foveal schisis with little or no change in foveal fluorescein angiography (Group 1), and three patients showed advanced macular changes with nonspe...
