Liposome-Mediated Delivery Improves the Efficacy of Lisosan G against Retinopathy in Diabetic Mice

Cells, 2023
Nutraceuticals are natural substances whose anti-oxidant and anti-inflammatory properties may be used to treat retinal pathologies. Their efficacy is limited by poor bioavailability, which could be improved using nanocarriers. Lisosan G (LG), a fermented

The Role of Sphingosine-1-Phosphate Receptor 2 in Mouse Retina Light Responses

Biomolecules, 2023
The bioactive sphingolipid sphingosine-1-phosphate (S1P) acts as a ligand for a family of G protein-coupled S1P receptors (S1PR1-5) to participate in a variety of signaling pathways. However, their specific roles in the neural retina remain unclear.

Enhancing Electroretinogram Classification with Multi-Wavelet Analysis and Visual Transformer

Sensors, 2023
The electroretinogram (ERG) is a clinical test that records the retina’s electrical response to light. Analysis of the ERG signal offers a promising way to study different retinal diseases and disorders.

Abnormal photoreceptor outer segment development and early retinal degeneration in kif3a mutant zebrafish [PDF]

, 2016
Photoreceptors are highly specialized sensory neurons that possess a modified primary cilium called the outer segment. Photoreceptor outer segment formation and maintenance require highly active protein transport via a process known as intraflagellar ...

Preoperative electrophysiological characterization of patients with primary macula-involving rhegmatogenous retinal detachment [PDF]

, 2018
Purpose: To determine 1) which components of retinal function are impaired after rhegmatogenous retinal detachment, 2) which outer retinal pathways (rod- or cone-driven) are more severely affected, and 3) whether there is concomitant inner retinal ...

Localized retinal degeneration secondary to Waldenström's macroglobulinemia

Oman Journal of Ophthalmology, 2017
A 52-year-old man, treated for Waldenström's macroglobulinemia (WM), continued to experience decreased vision even after 24 months. He was evaluated using multimodal imaging and electroretinography.

Diagnostic applications of the "pattern" electroretinography and visual evoked potentials in the evaluation of disorders of visual pathway function in Parkinson’s disease [PDF]

Vojnosanitetski Pregled, 2022
Background/Aim. In spite of continuous research efforts, specific laboratory, neuropsychological or neurophysiological tests for diagnosing Parkinson’s disease (PD) have not been established. The aim of the study was to determine the nature and extent of

Dark-adapted red flash ERGs in healthy adults [PDF]

, 2018
Purpose: The x-wave of the dark-adapted (DA) ERG to a red flash reflects DA cone function. This exploratory study of healthy adults aimed to investigate changes in the DA red ERG with flash strength and during dark adaptation to optimise visualisation ...
