Final answer:
Infectious scleritis is an inflammation of the sclera caused by an infection. Bacterial keratitis, which can also cause infectious scleritis, is an infection of the cornea commonly caused by bacteria. Contact lens wearers are at greater risk for developing bacterial keratitis due to improper lens care and bacterial adherence.
Step-by-step explanation:
Infectious scleritis is an inflammation of the sclera, which is the white outer layer of the eye, that is caused by an infection. There are various types of infections that can lead to infectious scleritis, including bacterial, viral, and fungal infections. The most common cause of infectious scleritis is bacterial infection, with certain bacteria such as Staphylococcus epidermidis and Pseudomonas aeruginosa being frequently involved.
Bacterial keratitis is an infection of the cornea, the clear front surface of the eye. It is often caused by bacteria such as Staphylococcus epidermidis and Pseudomonas aeruginosa, which can also cause infectious scleritis. Contact lens wearers are at greater risk for developing bacterial keratitis because contact lenses provide a surface for bacteria to adhere to and can cause corneal damage if not properly cared for.
