The clinical characteristics of DLB include cognitive decline, parkinsonian signs, fluctuations in cognition and attention, and visual hallucinations (3).
We sought to prospectively compare postoperative symptoms of dry eye, visual fluctuations, and foreign body sensation in patients undergoing LASIK and photorefractive keratectomy (PRK).
In a prospective clinical study conducted by our group, we have also reported that subjective symptoms of visual fluctuations and episodes of blurring of vision were greater after SMILE than LASIK in the early postoperative period [ 13].
In contrast, a previous study has reported a different set of symptoms (day-to-day visual fluctuations, intermittent diplopia, photopsia, high glare and visual hallucinations) [42].
Similar spontaneous fluctuations of eye position during resting-state and visual fixation were observed in all participants, as shown in Fig. S2.
DLB is characterized by dementia (a progressive cognitive decline with deficits in attention, executive functions, and visuospatial ability associated with fluctuations), visual hallucinations, and parkinsonism.
They showed a direct link between fluctuations in alpha (8 14 Hz) activity over posterior recording sites and visual cortex excitability, measured by the EEG while stimulating the visual cortex by means of TMS.
Visual observations, pressure fluctuations and steady gas tracer experiments showed that louver baffles can break bubbles, as indicted by the lower amplitudes and higher mean frequencies of differential pressure fluctuations, but they were only effective for superficial gas velocities <∼0.7 m/s for the FCC particles considered in this study.
DLB and PDD patients have dementia with visual hallucinations, attentional fluctuations, and parkinsonism.
Most of these studies [ 9, 20] have successfully used attributes of oscillations (i.e., levels of synchrony, fluctuation in amplitude) to link verbal processes with the left hemisphere and visual processes with the right hemisphere.
