| Case | Sex | Age, yrs | VA | Ophthalmologic Symptoms | Ophthalmologic Diagnosis | |
|---|---|---|---|---|---|---|
| OD | OS | |||||
| 1 | f | 65 | 1.2 | 1.2 | Vertical temporary diplopia of 2 weeks’ duration followed by hypotropia and ptosis, OD, and then esodeviation and abduction deficiency, OD | Partial oculomotor deficit, OD Abduction deficit, OD |
| 2 | f | 72 | 0.9 | 0.9 | Temporary diplopia (3 episodes within 8 days) | Not known |
| 3 | m | 76 | 0.8 | 0.9 | Temporary diplopia (1 episode, 1-day duration), followed by right inferior visual field loss, OD | Decompensated exophoria AION, OD |
