Electroretinography

Electroretinography (ERG) is a diagnostic test that measures the electrical activity of retinal cells in response to light stimuli. It is used to detect signals that reflect activity in retinal cells and can be used to determine retinal function in various models, including the light-damage model. ERG is distinct from electro-oculography (EOG), which monitors changes in the amplitude and orientation of the dipole of the eye.From: Handbook of Physics in Medicine and Biology [2019], Nano-Enabled Medical Applications [2020]

Leber congenital amaurosis (LCA) is a rare ocular disorder. It develops due to the inheritance of autosomal recessive genetic conditions causing severe loss of vision in infants. Vision loss is the result of retinal degeneration causing dysfunction of photoreceptors that precipitate an inability to capture images. Electroretinography (ERG) measures electrical retinal activity in response to impingement by light. The ERG tracings show diminished activity. Additional symptoms include cataracts, strabismus, photophobia, keratoconus, and/or nystagmus (4–5).

Although the abovementioned research provides valuable insights into the athletes’ visuomotor function and adaptability, the amount of studies performed with elite athletes is still limited. Future studies should focus on athletes from different sports to validate the current findings using both cross-sectional and longitudinal designs. Further, combined structural and functional investigations have to establish the causal link between adaptations in neural structure and function which could be achieved by combined EEG and (f)MRI/DTI research. Additional techniques such as optical coherence tomography or electroretinography could further provide information on early visual signal transmission in the retina.
