Methods and compositions for treatment of presbyopia, mydriasis, and other ocular disorders
The invention provides methods, compositions, and kits containing an alpha-adrenergic antagonist, such as phentolamine, for use in monotherapy or as part of a combination therapy to treat patients suffering from presbyopia, mydriasis, and/or other ocular disorders.
1. A method of treating presbyopia in a patient according to a monotherapy treatment regimen, comprising administering to an eye of a patient in need thereof a dosage of a single therapeutic agent, wherein the single therapeutic agent is phentolamine mesylate, the dosage is administered as an eye drop, the dosage of the single therapeutic agent is one eye drop of a 1% (w/w) phentolamine mesylate solution, and the method results in an improvement in near-vision visual acuity characterized by at least a two-line improvement in the patient's vision measured using a vision chart.
2. The method of claim 1 , wherein the method provides a therapeutic effect against presbyopia for a duration of at least 6 hours.
3. The method of claim 1 , wherein the method provides a therapeutic effect against presbyopia for a duration of at least 12 hours.
4. The method of claim 1 , wherein the method provides a therapeutic effect against presbyopia for a duration of at least 18 hours.
5. The method of claim 1 , wherein the method results in an improvement in near-vision visual acuity characterized by at least a three-line improvement in the patient's vision measured using a vision chart.
6. The method of claim 2 , wherein the method results in an improvement in near-vision visual acuity characterized by at least a three-line improvement in the patient's vision measured using a vision chart.
7. The method of claim 1 , wherein the patient experiences an increase in eye redness of no more than one grade measured using the CCLRU Redness Grading Scale compared to the patient's level of eye redness without receiving said dosage of single therapeutic agent.
8. The method of claim 2 , wherein the patient experiences an increase in eye redness of no more than one grade measured using the CCLRU Redness Grading Scale compared to the patient's level of eye redness without receiving said dosage of single therapeutic agent.
9. The method of claim 1 , wherein as a result of the administering, the patient experiences the effect of having a pupil diameter of less than 3.0 mm in the eye that received said dosage when measured under photopic conditions.
10. The method of claim 2 , wherein as a result of the administering, the patient experiences the effect of having a pupil diameter of less than 3.0 mm in the eye that received said dosage when measured under photopic conditions.
11. The method of claim 1 , wherein a therapeutic benefit occurs within 1 hour after administering the single therapeutic agent.
12. The method of claim 2 , wherein a therapeutic benefit occurs within 1 hour after administering the single therapeutic agent.
13. The method of claim 3 , wherein a therapeutic benefit occurs within 1 hour after administering the single therapeutic agent.
14. The method of claim 4 , wherein a therapeutic benefit occurs within 1 hour after administering the single therapeutic agent.
