Patients with keratitis sicca are more prone to which of the following?

Patients with keratitis sicca, also known as dry eye syndrome, experience a reduction in the quantity or quality of tears, leading to an insufficient tear film. This inadequate tear production not only results in discomfort and visual disturbances but also compromises the ocular surface defenses. The eyes rely on a stable tear film to wash away debris and provide antimicrobial properties, which are essential for maintaining eye health.

As a result, individuals with keratitis sicca are more susceptible to secondary infections. A compromised tear film can lead to corneal epithelial damage or microtraumas, making the ocular surface more vulnerable to pathogens. Since these patients have fewer natural defenses against infections like bacterial conjunctivitis or keratitis, they face an increased risk of secondary infections that could exacerbate their condition and potentially lead to more severe complications.

Understanding this connection highlights the importance of managing dry eye symptoms actively to protect the ocular surface and prevent secondary infections. While the other options listed may have associations with dry eyes, the direct link to increased vulnerability to infections is the most significant concern in the context of keratitis sicca.
