The term conjunctivitis covers all inflammatory processes affecting the conjunctiva. Bacterial and viral infections are the most frequent causes. Infectious conjunctivitis is rarely severe in industrialized countries, but trachomatous kerato-conjunctivitis is still the main cause of blindness all over the world. Most cases of bacterial conjunctivitis are treated with topical antibiotics. Viral conjunctivitis is frequent and, with the exception of herpetic conjunctivitis, has no specific treatment. Canaliculitis and dacryocystitis are rare but require specialized examination, treatment and follow-up.
Acute and general medical care facilities are often faced with the challenge of diagnosing and managing problems related to the external eye. Making the correct diagnosis, possessing knowledge of the natural course of the disease, and understanding the potential benefits and risks of topical ocular therapy are necessary for the proper management of an acute or chronic red eye.
Although they were once believed to be distinct diseases, many observers currently consider erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis to represent a mild-to-severe continuum of the same process. Each shares certain clinical, histologic, and etiologic characteristics; among the latter two are frequent ocular involvement. Because long-term ophthalmic sequelae may be catastrophic, early recognition and therapy of this acute oculocutaneous disease spectrum are critically important.
