Abstract
An eye model 10 includes a partially-spherical transparent disk 12 for representing a cornea, and a housing 14 attached to the disk 12 including a volume for holding a fluid representing aqueous within an eye. An annular ring 18 is attached to the housing 14 for representing an iris and a lens 20 is attached to the annular ring 18 for representing a lens of the eye. An end-cap 22 on an end opposite the disk 12 represents a retina.
Claims10
An eye model for use with diagnostic measurement systems comprising:
- a partially-spherical transparent disk for representing a cornea:
- a housing attached to the disk including a volume for holding a fluid representing aqueous within an eye;
- an annular ring attached to the housing for representing an iris;
- a lens attached to the annular ring for representing a lens of the eye;
- an end-cap on an end opposite the disk for representing a retina;
- and
- wherein the annular ring provides spacing between the ring and the housing for allowing air to escape from a space between the disk and the ring during filling of the housing with fluid.
An eye model for use with diagnostic measurement systems comprising:
- a partially-spherical transparent disk for representing a cornea;
- a housing attached to the disk including a volume for holding a fluid representing aqueous within an eye;
- an annular ring attached to the housing for representing an iris;
- a lens attached to the annular ring for representing a lens of the eye;
- an end-can on an end opposite the disk for representing a retina;
- and
- wherein the housing includes a flange adjacent the end-cap for preventing air bubbles from forming in a space between the disk and the ring when the model is placed on a side.
An eye model for use with diagnostic measurement systems comprising:
- a partially-spherical transparent disk for representing a cornea;
- a housing attached to the disk including a volume for holding a fluid representing aqueous within an eye and wherein at least a front portion of the housing is white for representing a sclera portion of the eye;
- an annular ring attached to the housing having a front rough-textured surface for representing an iris;
- a lens attached to the annular ring for representing a lens of the eye;
- an end-cap on an end opposite the disk for representing a retina having an orange surface facing the disk;
- and
- a flange adjacent the end-cap for preventing air bubbles from forming in a space between the disk and the ring when the model is placed on a side.
