Abstract
Speculums and spacers are used to position a retinal camera to obtain images of a fundus of an eye. In some instances, the speculums and spacers are designed to contact the eye to prevent rotation of the eye during imaging. In other instances, no contact is made with the eye. A light source may include visible light or limited to infrared light.
Claims4
A kit for use in imaging a fundus of an eye, comprising:
- A. a speculum comprising a first arm having a first blade and a second arm having a second blade, the first arm and the second arm coupled at a vertex, the first blade and the second blade configured to retract an upper and lower eye lid of the eye, respectively;
- B. a fundus camera comprising imaging optics and a housing and characterized by an optical axis, the housing containing the imaging optics and having an outer surface;
- and
- C. a camera spacer, comprising (I) a spacer body having an aperture extending therethrough, the aperture substantially centered about a longitudinal axis of the spacer, (II) a contact ring connected to a distal end of the spacer body and having a contact surface at a distal end and (III) a receptacle formed by a sidewall extending from a proximal end of the spacer body, for receiving a portion of the camera,
- whereby, when (i) the speculum is operatively positioned relative to the eye, (ii) the camera is disposed in the receptacle and (iii) the contact surface contacts the (a) the first arm and the second arm or (b) the first blade and the second blade, the optical axis and the longitudinal axis extend in a same direction such that the fundus camera is operatively positioned to image a fundus of the eye.
