Definition of glaucomatous visual field defects for level 1 evidence of glaucoma
| FDT test defects | Visual fields | ||||
|---|---|---|---|---|---|
| Normal | Definitely glaucoma | Probably glaucoma | Possibly glaucoma | Unlikely glaucomaa | |
| P <5 % | 2 or less non-adjacent | 4 | 3 | 2 adjacent | |
| P <2 % | 1 | 3 | 2 | 1 | |
| P <1 % | 0 | 2 | 1 non-edge | ||
| P <0.5 % | 0 | 1 | 1 non-edge | ||
| Comments | At any location in any hemi-field | At one hemi-field | At one hemi-field | If TDP plot is better than PDP plot | |
| Participants with glaucoma | Total | ||||
| Number of participantsb | 268 (100 %) | 252 (94 %) | 6 (2.2 %) | 9 (3.4 %) | 1 (0.4 %) |
| Number of eyes | 310 (100 %) | 283 (91.3 %) | 9 (2.9 %) | 13 (4.2 %) | 5 (1.6 %) |
