However, on hospital day three, pupillometer readings suggested that the patient's pupils were "sluggish" bilaterally (right NPi 0.7, left NPi 0.8) (Figure 1). Pupillary reactivity recovered within four days of symptom onset (by hospital day seven); however, it took several weeks for external ophthalmoplegia to resolve (Figure 1).
