Final answer:
Dendritic ulcer of the cornea is treated with topical antiseptics such as polyhexamethylene biguanide and chlorhexidine, and sometimes azoles. Advanced cases might require a corneal transplant. Use of corticosteroids is controversial due to potential worsening of the infection.
Step-by-step explanation:
The effective treatment of dendritic ulcer of the cornea typically involves topical antiseptics such as polyhexamethylene biguanide, chlorhexidine, or a combination of both, which are effective against conditions like Acanthamoeba keratitis. The treatment is intensive, often necessitating three to four weeks to resolve the infection. Additionally, azoles may be prescribed, and in more advanced cases of keratitis, a corneal transplant may be required to restore vision and prevent blindness. It is important to note that while corticosteroids can sometimes be used to reduce inflammation and pain, they are considered controversial due to immunosuppression which can exacerbate an infection.
