What symptom is commonly associated with a corneal abrasion?

A corneal abrasion is a superficial injury to the cornea, often resulting from trauma, foreign bodies, or contact lens use. The primary symptom associated with this condition is extreme pain, which occurs due to the cornea being rich in nerve endings. Patients experiencing a corneal abrasion may report sharp, stabbing pain, which can worsen with blinking or exposure to light.

Tearing often accompanies the pain as the eye attempts to flush out irritants or foreign bodies, and redness is a common finding due to inflammation and irritation of the affected area. These symptoms combine to make option B the most accurate representation of what a patient with a corneal abrasion would experience, as it reflects the intensity of discomfort and accompanying physical signs.

Other symptoms mentioned in the choices do not align with the common presentation of a corneal abrasion. For example, sudden vision loss suggests a more serious condition, such as retinal detachment or other intraocular problems, rather than a superficial corneal injury. Similarly, floaters and flashes often indicate retinal or vitreous issues, while persistent itching is more commonly associated with allergic reactions or conditions like conjunctivitis. Thus, option B stands out as the best description of the symptoms linked to a corneal abrasion.
