Which complication should be avoided when treating corneal ulcers with corticosteroids?

When treating corneal ulcers, the use of corticosteroids can lead to complications that may exacerbate the condition instead of promoting healing. Corticosteroids work by reducing inflammation and suppressing the immune response. However, in the case of corneal ulcers, using corticosteroids can suppress the local immune response, which is crucial for fighting infections. This immunosuppression can allow bacterial infections to worsen, potentially leading to more severe complications, such as perforation of the cornea.

In the context of corneal ulcers, avoiding immunosuppression is critical because an active immune response is needed to facilitate proper healing and to combat any existing or secondary infections. As such, the risk of failing to adequately manage infections due to suppressed immunity makes it crucial to consider corticosteroids with caution in these cases.
