| Ocular ischemic lesion | No. of Eyes (unmeasured or LP or NLPa) | Mean LogMAR±SD | Snellen Equivalent |
|---|---|---|---|
| None | 32 (2) | 0.24±0.31 | 20/35 |
| Anterior ischemic optic neuropathy (AION) | 26 (2) | 1.14±0.84 | 20/276 |
| Central retinal artery occlusion (CRAO) | 4 (1) | 2.10±0.85 | 20/2518 |
| Posterior ischemic optic neuropathy (PION) | 2 (1) | 2.00 | 20/2000 |
a
VA of 2 eyes without ocular ischemic lesions was not measured, 2 eyes with AION and 1 eye with CRAO had NLP vision and 1 eye with PION had LP vision.
