摘要: A device for causing concentric circles of illuminated light to be reflected from the human cornea. The device includes a cylindrical surface which is open at both ends. At one end the eye looks into the cylinder of the device and at the other end a camera or observer can view the illuminated rings on the cornea. The cylinder is advantageously made of transparent plastic or glass having an opaque coating. A lamp box is affixed to an uncoated portion of the device. The coating of the cylindrical surface through is interrupted to define clear rings on the cylindrical surface which light from the lamp box is conducted to be reflected from the cornea.

摘要: A retinal imaging system includes a light source and optics which receive light from the light source and which transmit the light to produce a beam that is substantially convergent. The beam penetrates a lens of an eye and diverges following penetration of the lens to illuminate an area of a retina of the eye. An imaging device receives a reflection of light from the retina.
