Pertussis is an infection of the respiratory tract caused by Bordetella pertussis commonly affecting the infants and the young children. Diphtheria-pertussis-tetanus vaccine is available for the prevention of the disease. However, pertussis has been reported in vaccinated individuals. It is characterized by paroxysms of cough, leading to various ocular manifestations such as subconjunctival hemorrhage, lid ecchymosis, and retinal hemorrhage. We report a case of a vaccinated boy who presented with ocular complaints and later diagnosed to be suffering from pertussis and treated successfully for the same.
