5. Visual field defects consistent with glaucomatous optic nerve damage with at least one of the following two findings:

   1. On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
   2. Glaucoma hemi-field test "outside normal limits."

6. Presence of any ocular pathology except for cataract

7. Narrow angle

4. Visual field defects consistent with glaucomatous optic nerve damage based on with at least one of the following two findings:

   1. On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
   2. Glaucoma hemi-field test "outside normal limits."

5. Glaucomatous optic nerve damage as evidenced by any of the following optic disc or retinal nerve fiber layer structural abnormalities:

   1. Diffuse thinning, focal narrowing, or notching of the optic disc rim, especially at the inferior or superior poles with or without disc hemorrhage;
   2. Localized abnormalities of the peripapillary retinal nerve fiber layer, especially at the inferior or superior poles; or
