Corneal burn symptoms? Let's talk about it.
Corneal burn symptoms?
Cornea is very important for us to see things in front of us in our life, because if we need to form a clear image on the retina, we must require the cornea to have transparency and appropriate refraction. Therefore, if there is a problem with the cornea, we will not be able to see it clearly.
There are many kinds of corneal burn, including chemical burn and thermal burn. Chemical burn of cornea simply means that acidic or alkaline substances enter the eye and burn the cornea, while thermal burn of cornea means that boiling oil and hot metal directly contact the cornea and damage the cornea.
Corneal burns first show a large area of epithelial exfoliation, followed by corneal edema and thickening, showing gray turbidity, and some severe symptoms may even lead to severe visual loss.
matters needing attention
Because the symptoms after corneal burn are more serious, some may even affect the vision of patients, some may cause vision loss, some may cause blindness, so we must protect our eyes in life.
