Retinal atheromatous plaques: their recognition by elevating the intraocular pressure.

Recognition and further study of existing retinal atheromatous plaques in the central retinal artery may be enhanced by pressure on the globe. This simple maneuver should be used when patients with transient ischemic attacks (cerebral or ocular) are examined with or without atheromatous disease of the carotid artery. Previously unseen or suspected plaques may be brought into view. Plaques already visible may appear larger or vary greatly in both color and texture giving indication of their composition. The recognition of these atheromatous plaques is important in the diagnosis of atheromatous disease.
