The effects of arc welding flash on the retina?

Hello Doctor: I have high myopia (left eye -775, right eye -650) and experience floaters.
I work in a factory and occasionally come into contact with welding-related tasks.
This afternoon, while working, I accidentally looked directly at the intense flash produced by welding from a distance of less than two meters (I was assisting and did not wear protective gear).
At that moment, a dark shadow appeared in the center of my vision, which gradually disappeared after about five minutes.
Currently (about three hours later), my vision is normal and there are no shadows.
I have a few questions for you: 1.
What kind of long-term effects can welding flashes have on the retina? 2.
Was the dark shadow I experienced (which has now disappeared) a visual afterimage or could it have caused damage to the retina? Thank you, Doctor.

Hello, Ashu:
1.
The ultraviolet rays generated during welding can more easily cause damage to the cornea, but there should be no significant harm to the retina in a short period of exposure.
2.
The black shadow experienced at that moment is due to the metabolism of rhodopsin in the retina not being able to keep up, resulting in the appearance of a dark spot, which will recover after resting.
There should be no harm to the retina.

More Info

Exposure to welding flash can pose significant risks to retinal health, especially for individuals with pre-existing conditions such as high myopia and floaters. The intense light produced during welding can lead to a phenomenon known as "arc eye" or photokeratitis, which is essentially a sunburn of the cornea. However, in your case, the concern extends beyond the cornea to the retina, particularly given your history of high myopia.

1. Impact of Welding Flash on the Retina: The intense light from welding can potentially cause damage to the retinal cells. This damage can manifest as temporary visual disturbances, such as the black shadow you experienced. In some cases, if the exposure is severe or prolonged, it could lead to more serious conditions like retinal burns or even retinal detachment. Given your high myopia, your retina may already be more susceptible to such injuries. High myopia is associated with a thinner retina and an increased risk of retinal tears and detachments, making it crucial to monitor any changes in your vision closely.

2. Understanding the Black Shadow: The black shadow you observed immediately after the exposure could be attributed to a few factors. It might have been a visual afterimage, which is a common response to sudden bright light exposure. However, it could also indicate that there was some temporary disruption in the retinal function due to the intense light. Since the shadow disappeared within a few minutes and your vision returned to normal, it suggests that the exposure may not have caused permanent damage. Nonetheless, it is essential to remain vigilant, as any sudden changes in vision should prompt a visit to an eye care professional.

Recommendations for Recovery and Monitoring:
- Immediate Care: If you experience any further symptoms such as persistent floaters, flashes of light, or changes in your vision, seek immediate medical attention. An eye examination, including a dilated fundus exam, can help assess the health of your retina and rule out any potential damage.

- Protective Measures: In the future, ensure that you wear appropriate eye protection when working near welding operations. Safety goggles or face shields designed to filter out harmful UV and intense visible light can significantly reduce the risk of retinal damage.

- Regular Eye Exams: Given your history of high myopia and floaters, regular eye examinations are crucial. These exams can help monitor the health of your retina and detect any changes early on.

- Awareness of Symptoms: Be aware of symptoms that may indicate retinal problems, such as sudden increases in floaters, flashes of light, or any significant changes in your visual field. If you notice any of these symptoms, do not hesitate to contact an eye care professional.

Conclusion:
While the immediate effects of welding flash may not have caused lasting damage, your history of high myopia necessitates a cautious approach. Regular monitoring and protective measures are essential to safeguard your retinal health. If you have any lingering concerns or experience new symptoms, consulting with an ophthalmologist is the best course of action to ensure your eyes remain healthy.
