Mutifocal techniques, in particular the multifocal ERG, are used in the diagnosis of ophthalmological diseases. The multifocal technique was developed in the early 1990s in the laboratory of Erich Sutter at the Smith-Kettlewell Eye Research Institute [ 1 ] [ 2 ] [ 3 ]
The multifocal ERG is used to record separate responses for different retinal locations. The international body concerned with the clinical use and standardization of the ERG, EOG, and VEP is the International Society for the Clinical Electrophysiology of Vision (ISCEV).
In diffusion weighted imaging (DWI), the intensity of each image element reflects the best estimate of the rate of water diffusion at that location.Because the mobility of water is driven by thermal agitation and highly dependent on its cellular environment, the hypothesis behind DWI is that findings may indicate (early) pathologic change.
In order to see a clear image, the eye must focus rays of light on to the light-sensing part of the eye – the retina, which is located in the back of the eye.This focusing – called refraction – is performed mainly by the cornea and the lens, which are located at the front of the eye, the anterior segment.
People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes (rings around lights), than with monofocal lenses.
Since 2021, ERG leaders and co-leads have received an annual bonus of $10,000 for their duties. They are nominated and interviewed for the role, and must be in good standing with their manager to ...
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception.
