Welding arc maculopathy is not a justifiable occupational hazard. Standard safety measures sufficiently prevent risks, with no significant differences found between welders and controls.

Area of Science:

  • Ophthalmology
  • Occupational Medicine
  • Visual Science

Background:

  • Investigating 'Welder's maculopathy' as a defined occupational disease.
  • Assessing the necessity of including welding-related eye conditions in occupational disease lists.

Observation:

  • 89 welders underwent ophthalmologic exams and multifocal electroretinography (MERG).
  • A control group of 81 non-welders was matched for comparison.
  • Pre-examination by an occupational medicine specialist was conducted for all participants.

Findings:

  • No significant morphological or functional differences in eyes between welders and controls.
  • Welders exhibited slightly better average visual acuity, potentially due to the healthy worker effect.
  • MERG and ophthalmological tests did not support 'Welding arc maculopathy' as a distinct occupational hazard.

Implications:

  • Current safety protocols in welding appear adequate to prevent maculopathy.
  • Welding arc maculopathy is more likely linked to accidents and safety breaches than inherent occupational risk.
  • Reclassifying the condition away from a standard occupational disease is suggested.
