Purpose:
|
Here we report high definition OCT features of early and late bilateral welding maculopathy.
|
|
Methods:
|
case report
|
|
Results:
|
Radiation in the visible and near infrared range penetrates deep into the eye which could result in thermal or photochemical retinal damaging. The most frequent welding induced damage is actinic keratitis which affects the ocular surface, rarely retinal structures may also be involved.
High resolution OCT in our case revealed an interruption in the inner segment/outer segment (IS/OS) layer which correlates closely with decreased visual acuity in our patient. These OCT findings have high similarity to our previous report of OCT findings in solar retinopathy.
|
|
Conclusion:
|
visual and infrared spectrum of emitted light from welding instrument could result in thermal and photochemical macular damage. This damage clearly revealed in high resolution OCT as IS/OS interruption which resulted in visual blurring.
We recommend standard protective devices for occupations exposing to high intensity lights such as welding even for brief period.
