MULTIFOCAL ELECTRORETINOGRAPHY IN THE ASSESSMENT OF EYES WITH CENTRAL RETINAL VEIN OCCLUSION [PDF]

Acta Medica Iranica, 2007
"nData suggest that the multifocal electroretinography (mfERG) may have a role in the assessment of patients with central retinal vein occlusion (CRVO). To explore the mfERG responses in patients with CRVO.

Case report: Autosomal recessive bestrophinopathy with macular cysts and MNV over 13-year follow-up

Frontiers in Genetics, 2022
Purpose: To describe the phenotype and genotype of a patient with autosomal recessive bestrophinopathy (ARB) over a 13-year follow-up period.Methods: The phenotype of the subject was described after a complete ophthalmological examination, which included

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Stray Light–Induced Multifocal Electroretinograms

Investigative Opthalmology & Visual Science, 2003
To evaluate the characteristics of stray light-induced response in multifocal ERG (mfERG) elicited by the stimulus falling on the disc.A patient with an enlarged optic disc (4 x 4 disc diameters of disc of normal fellow eye) and four normal volunteers served as subjects. The mfERGs elicited by different stimulus intensities (0.67-4.67 cd-sec/m(2)) were

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

Acta Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Slow flash multifocal electroretinogram in myopia

Vision Research, 2006
The purpose of this study was to investigate the characteristics of retinal function in myopes using a modified multifocal electroretinogram (mfERG) protocol, the slow flash (sf-mfERG) paradigm, which is thought to primarily reflect responses of ON- and OFF-bipolar cells and emphasize the late response components.Twenty-eight subjects (10 emmetropes ...

The positive correlation between the progressive photoreceptor damage and the increased macular leakage indicating the severity of diabetic retinopathy

Journal of Diabetes Investigation, EarlyView.
The dark area of photoreceptor cells, as measured by adaptive optics laser scanning ophthalmoscopy, shows significant enlargement with the progression of diabetic retinopathy (DR). A similar trend is observed for macular vascular leakage assessed by fundus fluorescein angiography. A positive correlation exists between these two parameters, suggesting a

Multifocal Electroretinography

Delhi Journal of Ophthalmology, 2010
Visual electrophysiological tests provide information about the functional integrity of the pigment epithelium (Electrooculogram or EOG), the photoreceptors and inner layers of the retina (electroretinogram or ERG), and the optic nerve and occipital ...

An n‐of‐1 gene‐directed drug repurposing trial for an ultrarare genetic condition

Epilepsia, Volume 67, Issue 7, Page 3644-3656, July 2026.
Abstract Objective Gain‐of‐function (GoF) variants in the KCNC1 potassium channel subunit gene (Kv3.1) cause motor/cognitive delays and hypotonia and have been associated with seizures. Fluoxetine has inhibitory effects on Kv3.1. However, open‐label nonrandomized administration is insufficient to guide clinical decision‐making in ultrarare conditions ...

Exploring the role of low‐dose atropine in myopia management in children with inherited retinal diseases

Optometry and Vision Science, Volume 103, Issue 4, April 2026.
ABSTRACT Purpose This study aimed to evaluate the effectiveness of low‐dose atropine in slowing myopic progression in children with inherited retinal diseases (IRDs) and myopia. Methods Retrospective study of children with IRDs, comparing myopia progression between those who received atropine drops and those who did not was conducted.
