Eye viewing device comprising video capture optics
View Patent ↗There is described in one embodiment an eye viewing device for viewing a structure of an eye such as a retina. The eye viewing device can include an image sensor. In one embodiment an eye viewing device can be adapted to facilitate both visual viewing of an eye structure and electronic image capture.
1. A retinal device for viewing a retina, said retinal viewing device comprising:
a portable housing having an observer end and a patient end;
an illumination system at least partially disposed in said housing;
an imaging system at least partially disposed in said housing;
an eyepiece lens for facilitating direct view of an eye structure by an observer at said observer end;
an electronic image sensor for generating image signals and providing indirect viewing of said eye observer;
a display supported by said portable housing; and
a moveable mirror movable between a first position, wherein said mirror is positioned so that a focal plane of said imaging system is defined substantially at an active surface of said electronic image sensor, and a second position wherein said mirror is positioned so that a focal plane of said imaging system is defined forward of said eyepiece lens, said moveable mirror enabling alternative viewing via said electronic image sensor and said eyepiece lens.
2. The retinal viewing device of claim 1 , wherein said device includes a communication link component for facilitating communication of image information externally from said portable housing, said image information corresponding to image signals generated by said electronic image sensor.
3. The retinal viewing device of claim 1 , wherein said device includes a communication link component for facilitating communication of image information externally from said portable housing, wherein said housing includes a holder for holding a replaceable module, and wherein said device includes a module replaceably held in said holder, said module including at least said electronic image sensor.
4. A retinal viewing device for viewing a retina, said retinal viewing device comprising:
a portable housing having an observer end and a patient end;
an illumination system at least partially disposed in said housing;
an imaging system at least partially disposed in said housing;
an eyepiece lens for facilitating direct view of an eye structure;
an image sensor for generating image signals;
a display supported by said portable housing;
a moveable mirror movable between a first position, wherein said mirror is positioned so that a focal plane is defined substantially at an active surface of said image sensor, and a second position wherein said mirror is positioned so that a focal plane of said imaging system is defined forward of said eyepiece lens; and
a communication link component for facilitating communication of image information externally from said portable housing, wherein said portable housing includes a holder for holding a replaceable module, wherein said device includes a module replaceably held in said holder, said module including at least said image sensor, and wherein said module and said holder include complementary mating connectors adapted to mate when said module is held in said holder.
5. The retinal viewing device of claim 1 , wherein said housing is a hand-held housing.
6. The retinal viewing device of claim 1 , wherein said device includes a wireless communication link component for facilitating wireless communication of image information externally from said housing, said image information corresponding to image signals generated by said electronic image sensor.
7. The retinal viewing device of claim 1 , wherein said portable housing includes a holder for holding a replaceable module, and wherein said display is disposed at said replaceable module.
8. The retinal viewing device of claim 7 , wherein said display is mounted at an interior of said replaceable module.
9. The retinal viewing device of claim 1 , wherein said display is mounted to said portable housing.
10. The retinal viewing device of claim 1 , wherein said display is one of detachably or pivotally mounted to said portable housing.
