Final answer:
Symptoms of an intraocular foreign body commonly include eye redness, blurred vision, sensitivity to light, and purulent discharge, which can lead to corneal scarring and blindness. Infections and inflammation often accompany these symptoms, and immediate medical evaluation is essential.
Step-by-step explanation:
The symptoms that usually indicate an intraocular foreign body is present include redness and irritation of the eye, blurred vision, and sensitivity to light. Additionally, there might be progressive corneal scarring, which, if left untreated, can lead to blindness. In the presence of a foreign body, inflammation of the conjunctiva can occur, manifesting as purulent discharge and potentially resulting in scarring, or even perforation, of the cornea. If an intraocular foreign body is suspected, immediate medical evaluation is critical to prevent permanent damage, such as blindness.
Infections such as conjunctivitis, blepharitis, and keratoconjunctivitis can be indicative of a foreign body presence or secondary complications from it. These infections are caused by bacteria or viruses, and symptoms can include fever and watery discharge that is commonly associated with viral infections. Inflammation of the conjunctiva with the presence of nodules might also suggest a foreign body or subsequent infection.
It is crucial for individuals, especially those over 40 years of age, who are at greatest risk for ocular conditions like glaucoma, to have their intraocular pressure tested routinely to detect excessive pressures that could suggest other eye conditions or damage.
