Asymmetric maculopathy with mutations in adenosine triphosphate-binding cassette, sub-family A, member 4 and jagged canonical notch ligand 1 after 30 years of monocular aphakia

open access: yesIndian Journal of Ophthalmology. Case Reports, 2021
We report an unusual case of asymmetric maculopathy in a patient with a 30-year history of monocular aphakia. An 82-year old man presented with unexplained visual loss in his right eye.

New insights into amiodarone induced retinal and optic nerve toxicity: functional and structural changes

open access: yesTherapeutic Advances in Ophthalmology, 2023
Background: Amiodarone is widely used for heart arrhytmia. Previous studies have suggested the possibility of optic neuropathy with the chronic use of this drug.

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

open access: yesEpilepsia, EarlyView.
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 ...

The oscillatory response of the electroretinogram and neuronal adaptation

open access: yesActa 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.

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

open access: yesJournal 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

open access: yesDelhi 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 ...
