Immediate symptoms:
• Intense pain and burning sensation: Alkaline solutions can cause immediate and severe pain. The pain may be excruciating and can continue for hours or even days.
• Tearing and watering of the eye: The eye will reflexively produce tears to flush out the harmful substance. Excessive tearing is a natural defense mechanism to try to dilute and remove the alkali.
• Blurred vision: The corneal surface, which is responsible for focusing light onto the retina, can be damaged by the alkaline solution. This can lead to blurred or distorted vision.
• Redness and inflammation: The tissues of the eye become inflamed and red as a reaction to the chemical injury.
Long-term consequences:
• Corneal damage: Alkaline solutions can cause significant damage to the cornea, including abrasions, scarring, and clouding. Corneal scarring can permanently impair vision.
• Conjunctival damage: The conjunctiva, the thin membrane covering the white part of the eye, can also be affected by alkaline substances, leading to inflammation and scarring.
• Uveitis: In severe cases, the inflammation can extend to the deeper structures of the eye, including the iris, ciliary body, and choroid. This condition is known as uveitis and can lead to serious complications.
• Blindness: Untreated or severe cases of alkaline eye injuries can result in permanent vision loss or even blindness.
It's essential to seek medical attention immediately if an alkaline solution gets into your eye. Prompt flushing with water and proper medical treatment can help minimize the damage and improve the chances of preserving vision. Never attempt to neutralize the alkaline solution with acidic substances, as this can cause further damage. Only trained medical professionals should handle alkaline eye injuries.
