ANIMAL EYE HEALTH

CROSS REFERENCE TO RELATED APPLICATIONS

[00011 This application claims priority to U.S. Provisional Application No. 61/671292 filed July 13, 2012, the disclosure of which is incorporated herein by this reference.

BACKGROUND OF THE INVENTION

Fi eld of the Invention

[0002] The. invention relates generally to devices and methods for measuring parameters associated with animal eye health and particularly devices aid methods for securing an animal's eye in position, while obtaining objective measurements associated with eye health.

Description of Related Art

[0003] Byes are a critical sensory organ for both humans and animals. Therefore, although eye diseases are typically not fetal, an eye disease or disorder that weakens vision or eventually results in loss of vision can significantly impair everyday life of a human or an animal.

[00041 Various types of devices diagnose eye health by projecting li ht into the eye of the patient. Such eye health measurement devices obtain light measurements regarding distortion, reflection, refraction, wavefrant changes and/or the like caused by components of the eye. These light measurements are used to determine the presence or absence of eye aberrations and the location of any eye aberrations. The effectiveness and accuracy of such devices are dependent upon proper positioning of the .measurement device relative to the eye, and sometimes more specifically the cornea and/or the pupil, and misalignment of the measurement device results in inaccurate measurements and potentially a misdiagnosis.

[0005} Thus, the eye being examined must have a specific position relative to the measurement device, such as a specific distance from the device, a specific height relative to the device, and specific angles relative to the device in both the vertical and horizontal planes. In addition, the eye must maintain, this position continuously as the device obtains the eye health measurements.

[0006] These requirements render eye health measurement devices unusable for most animals because animals typically will not "stay still," i.e. , maintain the same position for a time sufficient to measure the animaFs eye. For example, even if an animal .maintains its general body position for an amount of time, the animal will typically adjust the position of the head and thereby change the position of the eyes as the head moves,

[0007} Furthermore, for repeated examinations of an animal to produce measurements that can be compared, a consistent position of the animal's head and eyes in each examination is needed. Consistently positioning an animal relative to the measurement device is challenging, especially in view of the above-noted tendency of animals to frequently change their body position or at least their head position.

(0008} Moreover, the differences in facial structure between humans and animals also cause such eye health measurement devices to be difficult to use on animals. For example, many dogs have a nose that extends significantly farther than a human nose. As a result positioning the eye of the dog at the proper distance and angles relative to the measurement device can be problematic.

| ^' 0009| Therefore, there is a need for devices and methods for positionin ^' one or more eyes of an animal by securing the animal's head and eyes in position while obtaining objective measurements associated with eye health.

SUMMARY OF THE INVENTION

[0010) h is, therefore, an object of the invention to provide devices suitable for seeming the head and eyes of an animal in position while obtaining objective measurements associated with eye health.

[0011) it is another object of the invention to provide methods for securing an animal ^' s head and eyes in position while obtaining objective measurements associated with eye health.

[0012] it is yet another object of the invention to provide methods, for promoting the health or wellness of an animal by obtaining objective measurements associated with eye health.

[0013} It is still another object, of the invention to provide kits having devices and instructions for securing the head and eyes of an animal in position while obtaining objective measurements associated with eye health.

[0014] It is another object of the invention to provide packages and indicia describing the contents of the package including the device for securing the head and therefore the eyes of an animal in position.

[0015] One or more of these or other objects are achieved by providing a positioning device including a rest for receiving a portion of an animal's head and therefore securing the animal's head and eyes in position while obtaining objective measurements associated with eye health. The positioning device includes a pole configured ^' to enable the rest to pivot about a first axis of rotation and rotate about a second axis of rotation perpendicular to the first axis of rotation.- The positioning device can include a till adjusimeni member for pivoting the test about the first axis of rotation and a clocking adjustmen member for rotating the rest about the second axis of rotation. The positioning device can include a height adjustment member for moving the rest up and down the second axis of rotation,

[0016] Other and further objects, features, arid advantages of the present invention will be readily apparent to those skilled in the art,

The Invent on

[0030 j in one aspect, as shown in FIGS, 1 -3, the invention provides a positioning device 1 including a rest 16 having side flanges 26 extending at least partially upward therefrom. The rest 1 can have a substantially planar portion 28 located between the side flanges 26 and can also have a neck flange 27 extending outward and/or downward .from the substantially planar portion 28. The rest 1.6 receives a portion of an animal's head. For example, one of the side flanges 26 can contact at least a portion of a side of the animal's head, the other side flange 26 can contact at least a portion of the other side of the animal's head, the neck flange 27 can contact at least a portion of the animal's neck, and the substantially planar portion. 28 can contact at least a portion of the underside of the animal's head.

j ^' 0031] The device secures the eyes of an animal in position such that ob jective measurements associated with eye health can be obtained. The animal's eye is secured in position by securing the animal ^' s head in a manner that prevents any substantial movement of the animal's eye (eye socket) in relation to the device,

[0032 [ In an embodiment, the positioning device 1 includes a strap 29 that can. extend from at least one side of the rest 16 and can be configured to reversibly connect to at least one other side of the rest 1 . The length of the strap 29 can be adjustable. For example, the length of the strap 29 can be adjusted to accommodate the animal's head received by the rest 16 and secure the animal's head and/or eye in position relative to the rest .16, Depending on the facial structure of the animal, the strap 29 can secure the animal's head and/or the animal's eye in position relative to the rest 16 by at. least, partially encircling the nose of the animal, in an embodiment, the strap 29. the substantially planar portion 28, the neck flange 27 and/or the interior surfaces of the side flanges 26 are padded to reduce or prevent discomfort for the animal |O033j As shown in FIG. 2 _> the positioning device 1 includes a pole 5 configured to enable the rest 16 to pivot about a first axis of rotation 101 and rotate about a second axis of rotation 102 perpendicular to the first axis of rotation 101. The pole 5 can be co-linear with the second axis of rotation 102 such that the pole 5 is positioned on the second axis of rotation 102. Rotation of the pole 5 and/or the rest 16 about the second axis of rotation 102 can rotate the first axis of rotation 101 in the horizontal plane. As used herein, the term "horizontal plane" is the horizontal plane perpendicular to the second axis of rotation 102 and passing through the first axis of rotation 101, and the term "clocking" means the angle in the horizontal plane.

[0034] Referring again to FIG, I and FIG. 2, the positioning device 1 can include a device base 10 that can have a fixed position such that pivoting the rest 16 about the first axis of rotation 101. changes the angle of the rest 16 relative .to the device base 10 in the vertical plane. For example, pivoting the rest 16 about the first axis of rotation 101 decreases the distance from one end of the rest 16 to the device base 10 and increases the distance from the opposite end of the rest 16 to the device base 10, As used herein, the term 'Vertical plane" is the vertical plane perpendicular to the first axis of rotation 101 and passing through the second axis of rotation J 02, and the term "tilt" means the angle in the vertical plane,

|003S| Pivoting the rest 16 about the first axis of rotation 101 changes the tilt of the rest 1.6, and changing the tilt of the rest. 16 can position the animal's head and/or the animal's eye at a desired angle in the vertical plane. Rotating the rest 16 about the second axis of rotation 102 changes the clocking of the rest 16, and changing the clocking of the rest 16 can position the animal's head and/or the animal's eye at a desired angle in the horizontal plane.

(0036] In an embodiment, the positioning device 1 includes an attachment member 6 to which the rest 16 can be reversibly connected and disconnected. The positioning device 1 can include a tilt adjustment member 8 that can enable the rest 16 and/or the attachment member 6 to move to a desired tilt. For example, the tilt adjustment member 8 can be a first knob that can be rotatable in. one direction to enable the rest 16 to be pivoted and can be rotatable in an opposite direction to prevent the rest 16 from being pivoted.

{0037} In an embodiment, the positioning device 1 includes a retaining screw 20 that connects the rest 1 and/or the attachment member 6 to the pole 5, For example, the retaining screw 20 can extend through, the attachment member 6 and the pole 5 to the opposite side of the pole 5 to insert into the tilt adjustment member 8. [0038) The tilt adjustment member 8 can be rotatable in one direction to enable the rest. 16. to be pivoted and can be roiatabie in an opposite direction to prevent the rest 16 frorn being pivoted. For example, the tilt; adjustment member 8 can be rotated in one direction to loosen the connection between the tilt adjustment member 8 and the retaining screw 20. and the loosened connection can enable the rest 16 to pivot to a desired tilt. Then rotation of the tilt, adjustment member 8 in an opposite direction can tighten the connection between the tilt adjustment member 8 and the retaining screw 20.„ and the tightened connection can maintain the rest 16 at the desired tilt.

[0039 j When at least a portion of an animal's head is received by the rest 1 , the tilt adjustment member 8 can be rotated in the first direction to enable the rest 16 to pivot the animal's head, and/or the animal's eye to a desired tilt. Then the tilt ad ustment member 8 can be rotated in the second direction to prevent ^" the rest 1 iron) being pivoted such that the rest 16 maintains the animal's head and/or the animal's eye at the desired tilt.

jO!MOj The positioning device 1 can include a height, adjustment member 30 for moving the rest 16 up and down the second axis of rotation 102. The. pole 5 can connect to the height adjustment member 30. In an embodiment, the height adjustment member 30 includes a second knob 4 to which the pole 5 connects. The second knob 4 can be co-linear with the second axis of rotation 102 and/or the pole 5 such that the second knob 4 is positioned on the second axis of rotation 102.

[0941| In an embodiment, the height adjustment member 30 includes a stem 3 positioned on the second axis of rotation 102. The stem 3 can connect to the second knob 4 and/or the pole 5 such that rotation of the stem 3 rotates the pole 5 and/or the rest 16 relative to the second axis of .rotation. In an embodiment, the pole 5 and/or the second knob 4 include threads complementary to threads on the stem 3, and the complementary threads enable the second knob 4 to move along the second axis of rotation 102 if the second knob 4 is rotated. For example, rotation of the second knob 4 in one direction can move the second knob 4 up the second axis of rotation 102, and rotation of the second knob 4 in an opposite direction can move the second knob 4 down the second axis of rotation 102.

[0042f Moving the second knob 4 up the second axis of rotation 102 moves the pole 5 and/or the rest .16 up the second axis of rotation 102 to increase the distance between the rest 16 and the device base 10. Moving the second knob 4 down the second axis of rotation 102 moves the pole 5 and/or the rest 16 down the second axis of to decrease the distance between the rest 16 and the device base 10. As a result the height adjustment member 30. the second knob 4 and/or the stem 3 can adjust a height of the rest 16, and adjusting the height of the rest 16 can adjust the height of the animal's head received by the rest 16. For example, the second knob 4 can be rotated to move the animal's head and/or the animal's eye to a desired height.

|0043] The positioning device 1 can include a. release pin 12 that can insert at least partially through the pole 5, the second knob 4 and/or the stem 3 to prevent the pole 5 from moving up the second axis of rotation 102. For example, the release pin 12 can be inserted to prevent the pole 5 and the rest 16 from being pulled up and off of the second knob 4 if there is any upward force on these components either from the animal or human operator.

(0Θ44| hi an embodiment, the positioning device 1 includes a clocking adjustment member 13 to which the stem 3 connects. For example, the positioning device 1 can include one or more screws 35 inserted throug the stem 3 into the clocking adjustment member 13 to connect the stem 3 to the clocking adjustment member 13. The clocking adjustment member 13 can be rotatab!y connected to the device base 10. For example, the positioning device 1 can include a shoulder screw 14 and/or a shoulder washer 15 that connect the clocking adjustment member 13 to the device base i O, The shoulder screw 14 and the shoulder washer 15 can be co-linear with the second axis of rotation 102 to enable the clocking adjustment member 13 and/or the stem 3 to rotate on the second axis of rotation 102. In an embodiment, the clocking adjustment member 13, the stem 3, die pole 5 and die rest 16 are arranged to rotate together such that rotation of one of these components rotates the remainder of these components. For example, subjecting the clocking adjustment member 13 to a specific amount of rotation subjects the stem 3, the pole 5 and the rest 16 to the same amount of rotation.

[0045] The positioning device 1 can include an angle indicator 2 extending from the clocking adjustment member 13. For example, the angle indicator 2 can be connected to the clocking adjustment member 13 by screws 1 1 . Alternatively or additionally, the angle indicator 2 can. be integral with the clocking adjustment member 13. The device base 10 can have indicia 40 printed and/or formed thereon, and the angle indicator 2 can align with one of the indicia 40 on the device, base 10 to identity the clocking of the rest 16.

|0046j The positioning device 1 can include a spring lock pin ?, and the device base 10 can include holes 41 having a shape corresponding to the spring lock pin 7, The clocking adjustment member 13 can.. have .an aperture 43 through which the spring lock pin 7 can at least partially insert. For example, the spring lock pin 7 can at least partially insert throug the aperture 43 in the clocking adjustment member 13 into one of the holes 41 to prevent the clocking adjustment member 13, the stem 3, the pole 5 and/or the rest 16 from rotating on the second axis of rotation 102. To rotate the rest 16, the spring lock pin 7 can be removed from the hole 41 in which the spring lock pin 7 was inserted, and then the clocking adjustment member 13, the stem 3, the pole 5 and/or the rest 16 can be rotated on the second axis of rotation 102 to a desired clocking. Then the spring lock pin 7 can at least partially insert into another one of the holes 41 to prevent the clocking adjustment member 13, the stem 3, the pole 5 and/or the res 16 from rotating. Insertion of the spring Sock pin 7 can maintain the position of the rest 16, the animal's head and/or the animal ^' s eye at the desired clocking.

|004T| In. an embodiment the holes 41 are positioned at ten degree increments of rotation about the second axis of rotation 102. In an embodiment, the holes 41 are arranged such that the rest 16 can rotate one-hundred twenty degrees. However, other embodiments can. have any number of holes 41 and can have any maximum amount of rotation, and the positioning device i is not limited to a specific number of the holes 41 or a specific maximum amount of rotation.

[0048] The positioning device I can be made from any suitable material such as a polymer, a plastic and/or another synthetic material. For example, the positioning device 1 can be made from a polyethylene material such as linear low density polyethylene, polypropylene, polyethylene terephthalaie, and/or the like. Alternatively or additionally, the positioning device I can be manufactured from non-plastic materials including, but not limited to, glass; ceramic; cardboard; metal, such as aluminum or stainless steel; styroiham; and or the like.

10049) in an aspect shown in FIG, 3, the device base 10 can attach to an eye health measurement device 105. In an embodiment, the positioning device 10 can replace a human chin rest assembly. For example, a human chin rest assembly connected to the eye health measurement device 105 by connecting bolts (not shown) can be removed b loosening the connecting bolts, and then the positioning device I can be connected to the eye health measurement device 105 by inserting the connecting bolts through the device base 10.

fOOSOj in an embodiment, the eye health measurement device 105 is an aberrometer, a topographer or a combination thereof. For example, the eye health measurement device 105 can perform ray tracing by transmitting parallel light beams through the animal's pupil and determining where the light beams land on the animal's, retina. The landing locations can be used io measure the overall eye health and can be used to create a graphical display that can be analyzed to determine visual function. However, the eye health measurement device 105 can be any device that obtains objective measurements associated with eye health, and the eye health measurement device 105 is not limited to a specific embodiment,

{00511 The rest 16 receives at least a portion of an animal's head, positions the animal's head and secures the animal's eye m position relative to the eye health .measurement device 105. For example, the side flanges 26 can contact at least a portion of the sides of the animal's head, and the neck flange 27 can contact at least a portion of the animal's neck to -position the animal's head and secure the animal's eye in position relative to the eye health measurement device 105. The positioning device 1 can secure the animal's head and/or the animal' s eye in position at a desired position relative to the eye health measurement device 105. For example, the positioning device 1 can secure the animal's head and/or the animal's eye in position at a desired clocking, a desired tilt and/or a desired height.

0052| In an embodiment, in which eye health measurements of a dog are obtained, the rest 16 recei ves at least a portion of a dog's head, positions the dog's head and secures the dog's eye in -position relative to the eye health measurement device 105, For example, the side flanges 26 can contact at least a portion of the sides of the dog's head, and the neck flange 27 can contact at least a portion of the dog's neck to position the dog's head and secure the dog's eye in position relative to an eye heal h measurement device 105. The positioning device 1 can secure the dog's head and/or the dog's eye in position at a desired tilt, a desired clocking and/or a desired height relative to the eye health measurement device I OS. if the dog has a nose that extends a distance outward relative to the dog ^' s eye, the positioning device 1 can position the dog's head such that the dog's nose does not block positioning of the eye health measurement device 105 or transmission of light from the eye health measurement device 105 to the dog's eye,

[0053J In an aspect shown in FIG. 4, the rest 16 can be one of a plurality of rests 200 that have different sizes relative to each other. For example, the plurality of rests 200 can include a first rest 201 having a shorter neck flange relative to another one of the plurality of rests 200. The first rest 201 can. be suitable for an animal with a shorter neck than the animal for which the other rest is used. As another example, the plurality of rests 200 can include a second rest 202 having a longer neck flange relative to another one of the plurality of rests 200. The second rest 202 can be suitable for an animal with a longer neck than the animal, for which the other rest is used. As yet another example, the plurality of .rests 200 ^' can include a third, rest 203 having side flanges with a larger height relative to another one of the plurality of rests 200. The third rest

203 can be suitable for an animal with a larger head relative to the animal for which the other rest is used. Moreover, a fourth rest 204 can have side flanges that extend outward in addition to upward and can. have a longer neck flange relative to another one of the plurality of rests 200. The fourth rest 204 can be suitable for an animal with a larger head relative to the animal for which the other rest is used.

0054] The first rest 2 1. the second rest 202, the third rest 203 and the fourth rest 204 are merely examples, and the plurality of rests 200 can include any combination of rests. Each of the plurality of rests 200 can have different dimensions with respect to the substantially planar surface, the side flanges,, the neck flange and/or other components of the rest,

f0055| The plurality of rests 200 can be used with the positioning device 1 to secure the eye of an animal in position while obtaining objective measurements associated with eye health. One of the plurality of rests 200 can be selected based on the features of the animal and then attached to the pole 5. For example, a first, rest can be selected from the plurality of rests 200 and can reversibly connect to from the attachment member 6. The first rest can receive a portion of the animal's head, and the pole 5 can be configured to enable the first rest to rotate about at least one axis of rotation. The attachment member 6 can be configured to pivot relative to the pole 5 and mount the first rest on the pole 5,

(0056] in an embodiment, each of the plurality of rests 200 has a different size relative to each other. The side flanges of one of the plurality of rests 200 can have a different height relative to the side flange of at least one other one of the plurality of rests 200. The neck flange of one of the plurality of rests 200 can have a different length relative to the neck flange of at least one other one of the plurality of rests 200,

(0057) The first rest can be replaced by a second rest of the plurality of rests 200. For example, the second rest can be selected for use with an animal having different features relative to the animal with which the first rest was used, the first rest can be disconnected from the attachment member, and then the second rest can be connected to the attachment member. The second rest cars have at least one differently sized component relative to the first rest. (0058] In. yet another aspect, the invention provides a method for securing an animal's eye in position while obtaining objective measurements associated with eye health. The method includes positioning at least a portion of the animal's head in a device comprising a rest, and adjusting an angle of the animal's head in at least one of a vertical plane or a horizontal plane relative to a measurement device by rotating the rest to obtain the objective measurements. Adjusting the angle of the animal's head in the vertical plane relative to the measurement device can position the animal ^' s eye at a desired tilt, and adjusting the angle of the animal's head in the horizontal plane relative to the measurement, device can position the animal's eye at a desi ed clocking,

(0059] The method can include adjusting a height of the animal's head relative to the measurement device by moving the rest. In. an embodiment, positioning at least a portion of the animal's head includes positioning at least a portion of the animal's neck. ^' The method can .include securing the animal's head to the rest with a strap. In an embodiment, the measurement device can be one of an aberrometer, a topographer or a combination thereof For example, the measurement device can perform ray tracing by transmitting parallel light beams through the animal's pupil and determining where the light beams land on the animal's retina. The landing locations can be used to measure the overall eye health and can be used to create a graphical display that can be analyzed to determine visual function. However, the measurement device can be any device that obtains objective measurements associated with eye health.

(0O60| In an alternative aspect, the invention provides a method, for obtaining objective measurements associated with eye health. The method includes placing an animal's head on a positioning device comprising a rest that pivots about a first axis of rotation and rotates about a. second axis of rotation perpendicular to the first axis of rotation; and measuring one o more parameters associated with an eye of the animal.

(0061] In another alternative aspect, the invention provides a method for promoting the health or wellness of an animal. The method includes placing an animal's head on a positioning device; adjusting at least, one of an angle of the animal's head in the vertical plane, an angle of the animal's head in the horizontal plane, or a height of the animal's head using the positioning device; and obtaining objective measurements associated with eye health of the animal. The method can include providing a health protocol for the animal to follow based on the objective measurements. ( ^" 0062] In yet another alternative aspect, the invention provides a means for communicating information about or instructions for one or more of ( ^{ } a positioning device comprising a rest configured to pivot about a first axis of rotation and rotate about a second axis of rotation perpendicular to the first axis of rotation (2) using the positioning device to obtain objective eye health measurements; (3) cleaning the positioning device; (4) an eye health measurement device to be used with the positioning device; (5) instructions for securing an animal's eye for obtaining objective measurements associated with eye health; (6) instructions for obtaining objective measurements associated with eye health using the positioning device; or (?) instructions f or promoting the health or wellness of an animal using the positioning device.
