Systems and methods for treating eye diseases
A method may include accessing a terminal branch of an ophthalmic artery through a face of a subject. Additionally, the method may include positioning a device within the ophthalmic artery of the subject and treating at least one of a blockage, a stenosis, a lesion, plaque or other physiology in at least one of the ophthalmic artery or a junction between an internal carotid artery and the ophthalmic artery.
1. A method, comprising:
accessing a terminal branch of an ophthalmic artery through a skin of a head of a subject via a first device;
positioning the first device or a second device within the ophthalmic artery of the subject;
measuring a blood flow rate in the ophthalmic artery; and
treating a blockage, a stenosis, a lesion, plaque, or other physiology in the ophthalmic artery or a junction between an internal carotid artery and the ophthalmic artery, wherein the treating includes increasing a size of a lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery.
2. The method of claim 1 , wherein the accessing the terminal branch of the ophthalmic artery through the skin of the head of the subject includes accessing a supraorbital or supratrochlear artery of the subject via the first device.
3. The method of claim 1 , wherein the increasing the size of the lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery includes removing material.
4. The method of claim 1 , wherein the increasing the size of the lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery includes using a balloon in a balloon dilation procedure.
5. The method of claim 1 , wherein the measuring the blood flow rate in the ophthalmic artery includes measuring a linear blood flow rate.
6. The method of claim 1 , wherein the measuring the blood flow rate in the ophthalmic artery includes measuring a volumetric blood flow rate.
7. The method of claim 1 , further including stopping antegrade blood flow in the ophthalmic artery.
8. A method, comprising:
positioning a first device in a terminal branch of an ophthalmic artery through a skin of a head of a subject, wherein positioning the first device in the terminal branch of the ophthalmic artery through the skin includes positioning the first device in at least one of a supraorbital artery or a supratrochlear artery; and
treating a blockage, a stenosis, a lesion, plaque, or other physiology in the ophthalmic artery or a junction between an internal carotid artery and the ophthalmic artery, wherein the treating includes increasing a blood flow rate in the ophthalmic artery.
9. The method of claim 8 , wherein the treating further includes increasing a size of a lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery.
10. The method of claim 9 , wherein the increasing the size of the lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery includes removing material.
11. The method of claim 10 , wherein the increasing the size of the lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery includes using a balloon in a balloon dilatation procedure.
12. The method of claim 10 , wherein the increasing the size of the lumen in the ophthalmic artery or the junction between the internal carotid artery and the ophthalmic artery includes using an atherectomy device in an atherectomy procedure.
13. The method of claim 8 , further including inducing retrograde blood flow in the ophthalmic artery.
14. The method of claim 8 , further including measuring a blood flow rate in the ophthalmic artery.
15. The method of claim 14 , wherein the measuring the blood flow rate in the ophthalmic artery includes measuring a linear blood flow rate.
16. The method of claim 14 , wherein the measuring the blood flow rate in the ophthalmic artery includes measuring a volumetric blood flow rate.
17. A method, comprising:
locating a site in an arterial blood supply to an eye that compromises blood flow and contributes to an eye disorder;
accessing a terminal branch of an ophthalmic artery through a skin of a head of a subject via a first device;
delivering the first device or a second device intravascularly to the site; and
treating the site with the first device or the second device, wherein the site is located in the ophthalmic artery or a junction between an internal carotid artery and the ophthalmic artery.
18. The method of claim 17 , further including stopping antegrade blood flow in the ophthalmic artery or inducing retrograde blood flow in the ophthalmic artery.
19. The method of claim 18 , further including measuring the blood flow rate in the ophthalmic artery, including measuring at least one of a linear blood flow rate or a volumetric blood flow rate.
20. The method of claim 17 , wherein treating the site includes using a balloon in a balloon dilation procedure and/or using an atherectomy device in an atherectomy procedure.
