Summary

Rapid decompression significantly impairs rat retinal function, causing reduced mfERG amplitudes and delayed responses. These changes are most pronounced in the superior retina and juxtapapillary regions, indicating early-stage decompression sickness effects.

Area of Science:

  • Ophthalmology
  • Physiology
  • Baromedical research

Context:

  • Decompression sickness poses risks to divers and aviators.
  • Understanding early retinal dysfunction is crucial for risk mitigation.

Purpose:

  • To investigate the impact of rapid decompression on rat multifocal electroretinogram (mfERG).
  • To characterize early-stage retinal function impairment caused by decompression sickness.

Summary:

  • Rapid decompression led to increased noise, delayed latency, and reduced amplitude in rat mfERG.
  • mfERG analysis revealed significant reductions in P1 and N1 wave amplitudes, particularly in the superior retina and juxtapapillary regions.
  • These findings highlight characteristic mfERG changes indicative of early decompression sickness.

Impact:

  • This study provides objective electrophysiological evidence of retinal damage following rapid decompression.
  • The results can inform the development of diagnostic tools and protective strategies against decompression-induced visual impairment.
