Multifocal Electroretinography

Seminars in 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 ...

Evaluation of the Ophthalmotoxic Effect of Quantum Dots and Bioconjugates Based on Them in Terms of the Prospects for the Treatment of Resistant Endophthalmitis. Experimental Research (Stage 1)

Oftalʹmologiâ, 2021
Endophthalmitis remains one of the most formidable complications of surgery in ophthalmology, leading to significant functional and anatomical changes. The “gold” standard of treatment for this pathology is the installation of intravenous injections of ...

OculusGraphy: Signal Analysis of the Electroretinogram in a Rabbit Model of Endophthalmitis Using Discrete and Continuous Wavelet Transforms

Bioengineering, 2023
Background: The electroretinogram is a clinical test used to assess the function of the photoreceptors and retinal circuits of various cells in the eye, with the recorded waveform being the result of the summated response of neural generators across the ...

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.
