How do you treat an alkali burning eye?

Alkalis are especially dangerous to the eyes. In many cases, prompt and thorough rinsing of the eye (with saline or fresh water) dramatically reduces the risk of injury and long-term damage. It’s often better to go straight to the nearest tap than to wait for saline from the first aid kit.

Can alkali cause blindness?

Alkali burns may cause significant corneal scarring and blindness even if promptly treated.

Why is an alkali injury to the eye very destructive?

Alkali agents are lipophilic and therefore penetrate tissues more rapidly than acids. They saponify the fatty acids of cell cell membranes, penetrate the corneal stroma and destroy proteoglycan ground substance and collagen bundles. The damaged tissues then secrete proteolytic enzymes, which lead to further damage.

What is an alkali burn?

Alkali burns are caused by lye (e.g., Drano, Liquid Plummer), lime, or ammonia, in addition to other agents; they are characterized by liquefaction necrosis. They are worse than acid burns because the damage is ongoing.

What happens if you get alkaline in your eye?

Alkalis-chemicals that have a high pH-penetrate the surface of the eye and can cause severe injury to both the external structures like the cornea and the internal structures like the lens. In general, more damage occurs with higher pH chemicals.

How long does an eye chemical burn take to heal?

Early reparative phase (8-20 days) This is the transition period of ocular healing, in which the immediate regeneration of ocular surface epithelium and acute inflammatory events give way to chronic inflammation, stromal repair and scarring.

How long does it take for a chemical eye burn to heal?

Why are alkali burns worse than acidic?

Overall, alkaline agents are more toxic than acidic agents, due to the irreversible changes in protein and tissue damage.

Why do alkalis burn?

This involves the denaturing of proteins as well as saponification of adipose tissue, which does not limit tissue penetration. Alkalis cause deeper burns as they continue to penetrate the skin following initial contact. The mainstay of initial management of all chemical burns remains the same.

Can strong alkaline bases burn the eyes?

Alkali burns are the most dangerous. Alkalis-chemicals that have a high pH-penetrate the surface of the eye and can cause severe injury to both the external structures like the cornea and the internal structures like the lens.

How do doctors treat chemical burns?

Medical treatment Decontamination will begin (likely water irrigation). You will be given any antidote to counteract the chemical, if appropriate. Antibiotics often are not needed for minor chemical burns. Wounds will be cleaned and bandaged with medicated creams and sterile wraps as needed.

Can burned corneas heal?

The cornea repairs itself rapidly and usually heals without leaving any scars. In most cases, healing takes place in 1-2 days if you follow all instructions and protect your eyes from further damage.
