Total |
|---|---|---|---|---|
| Macular ring scotoma | 24b | 0 | 4 | 28 (43%) |
| Horseshoe surrounding fixation | 8 | 1 | 4 | 13 (20%) |
| Scotoma to one side of the fixation | 16 | 3 | 5 | 24 (37%) |
| Total | 48 (74%) | 4 (6%) | 13 (20%) |
a
Correct face field findings for a macular ring scotoma included seeing a ring scotoma (10 eyes), a partial ring scotoma (7 eyes), or diffuse blurriness of the face (7 eyes) on face fields. Correct face field findings for a horseshoe scotoma included seeing a ring scotoma (1 eye), a scotoma to the closed side of the horseshoe (5 eyes), or diffuse blurriness of the face (2 eyes).
b
One eye with a macular ring scotoma on both the SLO and the face field analysis also had a second eccentric, PRL with the scotoma superior in both evaluations. This was the only patient with two fixation loci observed in this study.
