Corneal foreign body (eye foreign body)
Eyes | Ophthalmology | Corneal foreign body (eye foreign body) (Disease)
If a patient has an object in their eye that shouldn’t be there it is called a foreign body, such as a speck of dust, wood chip, metal shaving, insect or piece of glass. The common places to find a foreign body are under the eyelid or on the surface of your eye.
The cornea is soft and many times the foreign object can become lodged in the cornea. If the foreign object is metal a rust ring can develop around the injury as well. If the foreign body and the rust ring is not removed a corneal scar can occur resulting in permanent vision loss.
Other symptoms of a foreign body in the eye include:
(1) Sharp pain in your eye followed by burning and irritation
(2) Watery and red eye
(3) Blurred vision or loss of vision in the affected eye
(4) Scratchy feeling when blinking
(5) Feeling that there is something in your eye
(6) Sensitivity to bright lights
(7) Bleeding into the white of the eye (subconjunctival haemorrhage).
