ABSTRACT:
An eye proptosing speculum that applies pressure to urge the eyeball outwardly is disclosed. The speculum includes a pair of blades and a pair of pressors. The pair of blades are opposingly situated and extend generally posteriorly. Each blade is shaped to engage the patient between one of the eyelids and the eyeball. The pair of pressors are also opposingly situated and extend generally posteriorly. One pressor extends from each blade and each pressor is shaped to engage and to exert pressure on the peripheral orbital contents. The pressure is transferred to the posterior orbital contents and then to a posterior region of the eyeball to proptose the eyeball outwardly. Each blade and each pressor, in combination, generally extend to follow the exterior surface of the eyeball, and each blade and each pressor is shaped to minimize extrinsic pressure directly on the eyeball. The eye proptosing speculum has a pair of arms attached to and cooperating with each other, with one blade being attached to each of the arms. Preferably, the speculum has an adjustment device for adjustably fixing the distance between the free ends of the arms.
