In one aspect, a speculum is provided herein which includes a first arm having a first channel formed thereon adapted to the shape of an eyelid a second arm having a second channel formed thereon adapted to the shape of an eyelid a hinge unitarily formed with the first and second arms, the hinge permitting the first and second arms to selectively rotate about an axis rotation, the selective rotation causing the first and second channels to selectively move closer and farther apart and, a position retaining arrangement. The position retaining arrangement includes a first element formed unitarily with the first arm, and a second element formed unitarily with the second arm. The first and second elements are configured to cooperatively retain the first and second arms in a selected rotational position. Advantageously, with the subject invention, a unitary speculum may be formed which includes an adjustable position retaining arrangement.
