RESUMO
Human infection with the sheep nasal botfly Oestrus ovis occurs sporadically. In most cases, there is a history of a strike in the eye by the adult fly. Human O. ovis has been reported rarely from the Americas. We report the first case of O. ovis infection in the Caribbean region, which occurred in an urban area of Barbados. The patient responded to removal of the larvae from the conjunctiva and symptomatic treatment.

The intraocular expansion of perfluoromethane (CF4), perfluoroethane (C2F6), and perfluoropropane (C3F8) was determined by a direct method for measuring intravitreal gas. A bubble of CF4 was found to expand 1.9 times the volume initially injected; C2F6 expanded 3.3 times; C3F8 expanded four times. The expansion characteristics of the experimental gases were compared with those of sulfur hexafluoride (SF6) and octofluorocyclobutane (C4F8), two gases already in clinical use.
