Chlorogenic Acid Supplementation Improves Multifocal Electroretinography in Patients with Retinitis Pigmentosa
To evaluate the effect of chlorogenic acid supplementation in patients with retinitis pigmentosa, we evaluated objective change in visual function with multifocal electroretinography, along with visual acuity, visual field, standard electroretinography, and contrast sensitivity. Eighteen patients diagnosed with retinitis pigmentosa were enrolled in this prospective, non-comparative, single-arm ...
متن کاملFull-Field versus Multifocal Electroretinography
Full field electroretinography (ffERG) or conventional electroretinography represents the summed electrical response of the entire retina evoked by a flash light from an arc bowl (Ganzfeld stimulus bow) scattered in the eye through a dilated pupil. Clinical applications of ffERG were initiated in the 1940s, therefore clinical and basic studies on ERG date back to several decades. In 1989, the I...
متن کاملMultifocal electroretinography in patients with Stargardt's macular dystrophy.
AIMS To describe the topography of multifocal electroretinograms (ERGs) and to explore its diagnostic value in patients with Stargardt's macular dystrophy (SMD). METHODS 51 patients with SMD were examined by means of the m-sequence technique to characterise the topography of electroretinographic responses in the central visual field. The results were compared with data from 30 normal voluntee...
متن کاملAnalysis with support vector machine shows HIV-positive subjects without infectious retinitis have mfERG deficiencies compared to normal eyes.
PURPOSE To test the following hypotheses: (1) eyes from individuals with human immunodeficiency virus (HIV) have electrophysiologic abnormalities that manifest as multifocal electroretinogram (mfERG) abnormalities; (2) the retinal effects of HIV in immune-competent HIV individuals differ from the effects in immune-incompetent HIV individuals; (3) strong machine learning classifiers (MLCs), like...
متن کاملBilateral Progressive Vision Loss in Noninfectious HIV Retinopathy without Infectious Retinitis
Vision loss is rarely associated with noninfectious human immunodeficiency virus (HIV) retinopathy in HIV positive patients with normal CD4 counts. 1 Ophthalmologists should be aware that HIV retinopathy may be the cause of visual loss in a subset of HIV patients without infectious neuroretinitis who are otherwise stable. Electrophysiological testing has high diagnostic value in these patients....
