Abstract

Abstract An apparatus for detecting ophthalmic diseases such as an inflammation in the camera oculi (11a) of a patient's eye which includes means for focussing a laser beam (1) at a selected spot in the camera oculi of an eye (11), and according to which the light scattered from the eye is photoelectrically detected and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection in the camera oculi of the patient's eye.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 125 words
An apparatus for detecting ophthalmic diseases in the camera oculi of a patient's eye comprising a laser source (1) for producing a laser beam, means for focussing said laser beam at a selected spot in the camera oculi (11a) of said patient's eye, and photoelectric converting means (27) for receiving light scattered from said camera oculi and converting it into an electric signal, characterized in that a counter (40) is provided for counting the intensity of said scattered light in terms of the number of photons in response to an electrical signal received from said photoelectric converting means, and that the output signal of said counter is evaluated to derive therefrom the protein concentration due to the inflammation in the camera oculi of said eye.
Claim 2
Independent Claim 125 words
An apparatus for detecting ophthalmic diseases in the camera oculi of a patient's eye comprising a laser source (1) for producing a laser beam, means for focussing said laser beam at a selected spot in the camera oculi (11a) of said patient's eye, and photoelectric converting means (27) for receiving light scattered from said camera oculi and converting it into an electric signal, characterized in that a counter (40) is provided for counting the intensity of said scattered light in terms of the number of photons in response to an electrical signal received from said photoelectric converting means, and that the output signal of said counter is evaluated to derive therefrom the protein concentration due to the inflammation in the camera oculi of said eye.
Claim 3
Dependent Claim 24 words
An apparatus according to claim 1, wherein said laser beam is scanned to displace said selected spot at which said laser beam is focussed.
Claim 4
Dependent Claim 15 words
An apparatus according to claim 1, wherein said photoelectric converting means is a photomultiplier (27).
