RESUMO
Infectious conjunctivitis is a very common presentation to medical professional and ophthalmologist all over the world. Although its typically self-limiting and treatable in almost all of the cases, but we need to be aware of the rare and potentially life threatening if the cause is not promptly identified and treated accordingly. In our case report, we highlighted the rare case of Neisseria meningitidis as a primary cause of keratoconjunctivitis. Neisseria meningitidis is a rare etiology of keratoconjunctivitis and its ocular presentations are quite similar with other bacterial or viral infection. The infection may potentially fatal if systemic invasion occurred, however with immediate and proper treatment the outcome is satisfactory. Early diagnosis and proper antibiotic treatment are critical to prevent systemic spread of the infection. Public health intervention is needed to prevent outbreak of the disease.
