Can electrooptic ophthalmia have sequelae?

summary

Electro optic ophthalmia is an inflammation caused by the damage of ultraviolet rays to cornea and conjunctival epithelium. Also known as snow blindness. It is characterized by redness and swelling of eyelids, congestion and edema of conjunctiva, severe foreign body sensation and pain, fear of light, tears and inability to open eyes, and blurred vision during the onset. Can electrooptic ophthalmia have sequelae? Next, I'd like to share my views with you.

Can electrooptic ophthalmia have sequelae?

Electro optic ophthalmia will not have sequelae, because the cornea is divided into five layers, the outermost upper cell layer, followed by the outer elastic layer, the middle stromal layer, then the inner elastic layer, and the innermost endothelial cell layer. And the outermost epithelial cell layer has strong regeneration ability, and it can be repaired quickly after damage without leaving any trace. Therefore, if UV damage only damages the epithelial cell layer, there is no big problem. It will be better soon, but if it involves the basement membrane of the epithelial cell layer, it will recover more slowly.

In the environment of strong light, you should wear sunglasses or color changing glasses to reduce the irritation of ultraviolet rays to the eyes. This is the best way to prevent electro-optic ophthalmia. Welding operators and personnel assisting in supporting weldments shall wear protective masks.

If the protective mask cannot be found at the moment, the face should be turned to the back of the side before the arc light is generated, and the eyes should be closed tightly to avoid the arc light directly irradiating the eyeballs. People around the welder or pedestrians passing by the machine should turn their face to the back when arc light appears.

matters needing attention

Improve the working environment: for example, when several welding machines work at the same time in the room, it is better to set an isolation barrier in the middle to avoid mutual influence, and paint zinc white, chrome yellow and other substances on the wall to absorb ultraviolet light. Try not to carry out welding operation outdoors, so as not to affect others.
