Abstract
Abstract Ophthalmologic apparatus includes a light source for obliquely directing light beams into an eye to be examined to illuminate a region of interest therein, a lens system for viewing the region of interest, an optical magnifier assembly for magnifying the viewed region of interest, and an image intensifier for intensifying the image of the viewed region of interest. The light source directs light into the eye from opposite sides thereof to intersect in the plane of the region of interest in the eye.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
104 words
Ophthalmologic apparatus, comprising: illuminating means for directing light into an eye to be examined to illuminate a region of interest therein; a lens system for viewing said region of interest of the eye to be examined; an optical magnifier assembly for magnifying the viewed region of interest; and an image intensifier for intensifying the image of the viewed region of interest; wherein said illuminating means comprises: an annular light source; and an annular reflector coaxial with said annular light source for reflecting the light into the eye from all sides thereof to intersect in the plane of the region of interest in the eye.
Claim 2
Dependent Claim
104 words
Ophthalmologic apparatus, comprising: illuminating means for directing light into an eye to be examined to illuminate a region of interest therein; a lens system for viewing said region of interest of the eye to be examined; an optical magnifier assembly for magnifying the viewed region of interest; and an image intensifier for intensifying the image of the viewed region of interest; wherein said illuminating means comprises: an annular light source; and an annular reflector coaxial with said annular light source for reflecting the light into the eye from all sides thereof to intersect in the plane of the region of interest in the eye.
Claim 3
Dependent Claim
35 words
The apparatus according to claim 1, wherein said illuminating means comprises means for changing the axial distance between the annular light source and the annular reflector to change the plane of intersection of the light.
Claim 4
Dependent Claim
47 words
The apparatus according to claim 1, wherein said annular light source comprises an annular array of point light emitters, and means for changing the angle of said light emitters with respect to the axis of said annular array to change the plane of intersection of the light.
Claim 5
Dependent Claim
18 words
The apparatus according to claim 1, wherein said lens system includes a contact lens engageable with the eye.
Claim 6
Dependent Claim
53 words
The apparatus according to claim 1, wherein said lens system, optical magnifiyer assembly and image intensifier are included within a housing, and wherein said housing further includes an attachment for attaching a laser thereto, and directing means for directing a laser beam emitted from said laser to said viewed region of the eye.
Claim 7
Dependent Claim
47 words
The apparatus according to claim 1, wherein said lens system, optical magnifiyer assembly and image intensifier are included within a housing, and wherein said housing further includes an eyepiece for eye viewing the region of interest, and a video camera for camera viewing the region of interest.
Claim 8
Dependent Claim
74 words
Ophthalmologic apparatus, comprising: illuminating means for directing light into an eye to be examined to illuminate a region of interest therein; a lens system for viewing said region of interest of the eye to be examined; an optical magnifier assembly for magnifying the viewed region of interest; an image intensifier for intensifying the image of the viewed region of interest; and an endoscope adapted to penetrate the eye for viewing a selected region thereof.
Claim 9
Dependent Claim
74 words
Ophthalmologic apparatus, comprising: illuminating means for directing light into an eye to be examined to illuminate a region of interest therein; a lens system for viewing said region of interest of the eye to be examined; an optical magnifier assembly for magnifying the viewed region of interest; an image intensifier for intensifying the image of the viewed region of interest; and an endoscope adapted to penetrate the eye for viewing a selected region thereof.
Claim 10
Dependent Claim
73 words
Ophthalmologic apparatus, comprising: an annular light source; an annular reflector coaxial with said annular light source for reflecting the light into an eye from all sides thereof to intersect in the plane of a region of interest in the eye; a housing including a lens system for viewing said region of interest of the eye to be examined; and an optical magnifier assembly within said housing for magnifying the viewed region of interest.
Claim 11
Dependent Claim
73 words
Ophthalmologic apparatus, comprising: an annular light source; an annular reflector coaxial with said annular light source for reflecting the light into an eye from all sides thereof to intersect in the plane of a region of interest in the eye; a housing including a lens system for viewing said region of interest of the eye to be examined; and an optical magnifier assembly within said housing for magnifying the viewed region of interest.
Claim 12
Dependent Claim
35 words
The apparatus according to claim 8, Wherein said illuminating means comprises means for changing the axial distance between the annular light source and the annular reflector to change the plane of intersection of the light.
Claim 13
Dependent Claim
47 words
The apparatus according to claim 9, wherein said annular light source comprises an annular array of point light emitters, and means for changing the angle of said light emitters with respect to the axis of said annular array to change the plane of intersection of the light.
Claim 14
Dependent Claim
18 words
The apparatus according to claim 8, wherein said lens system includes a contact lens engageable with the eye.
Claim 15
Dependent Claim
23 words
The apparatus according to claim 8, wherein the apparatus includes an endoscope adapted to penetrate the eye for viewing a selected region thereof.
Claim 16
Dependent Claim
37 words
The apparatus according to claim 8, wherein said housing further includes an attachment for attaching a laser thereto, and directing means for directing a laser beam emitted from said laser to said viewed region of the eye.
