An inflammation of the cornea, keratitis is a condition caused by viruses, fungi, bacteria and parasites. It can also occur from wearing contact lenses for too long or an injury from an object that scratches the surface of the cornea. Its treatment depends on the cause. For a noninfectious keratitis, the patient may require topical eye medications. For infectious keratitis, the patient needs antibacterial, antiviral or antifungal eyedrops, as detailed by Mayo Clinic.

Conjunctivitis is an infection that inflames the transparent membrane that covers the white part of the eye. Its causes include bacteria, viruses and allergens such as pollen. Treatment for bacterial conjunctivitis involves the use of ointment, particularly in children. In the case of allergic conjunctivitis treatment, doctors may prescribe antihistamines such as Benadryl or Claritin to stop the inflammation. However, viral conjunctivitis has no cure, as Healthline explains.

Trachoma is a bacterial infection and is contagious, and it can spread through contact with the eyelids, eyes or nose secretions. It may cause eyelid swelling, irritation and itching of the eye. Treatment of this infection involves the use of antibiotics such as oral azithromycin and certain ointments. In severe cases, such as eyelid deformities, trachoma may require surgical treatment, according to Mayo Clinic.
