Abstract
Abstract A reading or symbol-recognition test capable of being administered to a large examination group of children which produces blurred vision only in those of the group who are possibly dysmetric dyslexic. The test which induces an eye oscillation of a selected extent which is normally below the level which produces blurred vision in those not affected with dysmetric dyslexia requires no more effort on the part of the participants than that required in watching a movie, and thus serves as an effective diagnostic screening procedure, even for pre-school children with cerebellar-vestibular dysfunctions who have not as yet even exhibited poor or refractory response to reading instruction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
A group diagnostic screening procedure for identifying those in said group possibly having the condition of dysmetric dyslexia, which is based on the discoveries of a cerebellarvestibular dysfunction and resulting sub-clinical eye oscillation indicative of said condition, said procedure comprising the steps of inducing an eye oscillation of a selected extent which is normally below the threshold level producing blurred vision, but which, when in additive relation to said sub-clinical eye oscillation, is above said Threshold level, and automatically identifying those experiencing blurred vision as possibly being dysmetric dyslexic.
Claim 2
Dependent Claim
89 words
A group diagnostic screening procedure for identifying those in said group possibly having the condition of dysmetric dyslexia, which is based on the discoveries of a cerebellarvestibular dysfunction and resulting sub-clinical eye oscillation indicative of said condition, said procedure comprising the steps of inducing an eye oscillation of a selected extent which is normally below the threshold level producing blurred vision, but which, when in additive relation to said sub-clinical eye oscillation, is above said Threshold level, and automatically identifying those experiencing blurred vision as possibly being dysmetric dyslexic.
Claim 3
Dependent Claim
44 words
The dysmetric dyslexia diagnostic screening procedure as defined in claim 1 wherein said eye oscillation which is induced in said examination group is that resulting from a visual display moving across the line of vision of said group at a selected rate of speed.
Claim 4
Dependent Claim
32 words
The dysmetric dyslexia diagnostic screening procedure as defined in claim 2 wherein for children in an age group under nine years, said rate of speed is 5 feet per second or below.
Claim 5
Dependent Claim
116 words
A group diagnostic screening procedure for identifying those in said group possibly having the condition of dysmetric dyslexia which is based on the discoveries of a cerebellar-vestibular dysfunction and resulting sub-clinical nystagmus indicative of said condition, said procedure comprising the steps of requiring the visual fixations of said examination group upon a point on the foreground of a visual display having a movable background, and then moving said background to induce a mild nystagmus interfering with said visual fixation which is normally below the threshold level producing blurred vision but which, when in additive relation to said sub-clinical nystagmus, is above said threshold level, and automatically identifying, those experiencing blurred vision as possibly being dysmetric dyslexic.
Claim 6
Dependent Claim
116 words
A group diagnostic screening procedure for identifying those in said group possibly having the condition of dysmetric dyslexia which is based on the discoveries of a cerebellar-vestibular dysfunction and resulting sub-clinical nystagmus indicative of said condition, said procedure comprising the steps of requiring the visual fixations of said examination group upon a point on the foreground of a visual display having a movable background, and then moving said background to induce a mild nystagmus interfering with said visual fixation which is normally below the threshold level producing blurred vision but which, when in additive relation to said sub-clinical nystagmus, is above said threshold level, and automatically identifying, those experiencing blurred vision as possibly being dysmetric dyslexic.
Claim 7
Dependent Claim
45 words
The dysmetric dyslexia diagnostic screening procedure as defined in claim 4 wherein said foreground material consists of words and said background material consists of pictorial representations, and said background material is moved at a rate of speed of approximately 4 feet per second or below.
Claim 8
Dependent Claim
94 words
A diagnostic screening procedure for identifying the condition of dysmetric dyslexia, which is based on the discoveries of a cerebellar-vestibular dysfunction and a resulting sub-clinical eye oscillation indicative of said dysfunction, said procedure comprising the steps of inducing an eye oscillation in a patient being examined of a selected extent which is normally below the threshold level producing blurred vision, but which, when in additive relation to said sub-clinical eye oscillation, is above said threshold level, and noting that the experiencing by said patient of blurred vision indicates the possible existence of dysmetric dyslexia.
Claim 9
Dependent Claim
94 words
A diagnostic screening procedure for identifying the condition of dysmetric dyslexia, which is based on the discoveries of a cerebellar-vestibular dysfunction and a resulting sub-clinical eye oscillation indicative of said dysfunction, said procedure comprising the steps of inducing an eye oscillation in a patient being examined of a selected extent which is normally below the threshold level producing blurred vision, but which, when in additive relation to said sub-clinical eye oscillation, is above said threshold level, and noting that the experiencing by said patient of blurred vision indicates the possible existence of dysmetric dyslexia.
Claim 10
Dependent Claim
56 words
The dysmetric dyslexia diagnostic screening procedure as defined in claim 6 wherein said eye oscillation which is induced in said patient is that resulting from a visual display moving across his line of vision at a selected rate of speed said display consisting of foreground and background material operatively arranged for movement independently of each other.
Claim 11
Dependent Claim
31 words
The dysmetric dyslexia diagnostic screening procedure as defined in claim 7 wherein for a patient under nine years of age said rate of speed is five feet per second or below.
