Which of the following statements is false regarding corneal ulcers?

The statement that corneal ulcers always lead to permanent vision loss is false because not all corneal ulcers result in lasting damage to vision. In many cases, corneal ulcers can be effectively treated if diagnosed early, leading to complete healing without long-term visual impairment. Treatment options can include antibiotics, antifungal medications, or antiseptic drops, which help to resolve the infection and reduce inflammation. Therefore, while some severe or untreated corneal ulcers may indeed lead to vision loss, it is not accurate to state that all cases will inevitably result in this outcome.

On the other hand, corneal ulcers can be of little concern in specific situations, especially if they are small and superficial, and do not compromise vision significantly. They may cause discomfort and redness due to the inflammation and presence of pathogens, which is a common symptom. Infections, whether bacterial, viral, or fungal, are well-documented causes of corneal ulcers, highlighting their multifactorial nature.
