“…Journal of Ophthalmology are obtained when calculating by how many standard deviations the performance of an examinee deviate from the mean of the normative database provided by IBS software. Adding the standard scores for stability, Fourier intensities of ∼0.3 and ∼1.00 Hz, and synchronizations, a fall index is graded as minimum falling risk (0-36), moderate level (37-58), high level (58-100), according to which precautions and supportive treatment can be planned [8,17].…”

Purpose. To compare perioperative visual field (VF), balance functions (BF), and changes in the other ocular parameters in patients undergoing upper eyelid dermatochalasis (DC) surgery. Methods. One hundred and fifty-eight eyes of 79 patients who underwent DC surgery were included in the study. The VF, BF, intraocular pressure (IOP), pachymetry (PM), macular, and optic nerve measurements were recorded. Measurements were repeated at postoperative month 1. The preoperative and postoperative ocular measurements and the balance data were compared. Results. Nineteen of 79 (24.05%) patients were male and 60 of 79 (75.95%) were female, while the mean age of the patients was 58.65 ± 7.38 years. There were statistically significant differences in terms of VF and macular thickness between the preoperative and postoperative values. The improvements in mean defect, standard loss variance, and mean sensitivity values of global VF parameters in both eyes were statistically significant after surgery. Central macular thickness, mean macular thickness, and macular volume decreased significantly in all eyes after surgery (p<0.05). Conclusions. Although a marked improvement was observed in VF and peripheral vision after surgery, no significant change was found in BF parameters including primarily falling risk. The significant change in the macular parameters was only remarkable, and we think that the decrease was due to subtle vasospasm. There is a need for further comprehensive studies including especially patients older than 65 with a view to understanding the effect of DC surgery on BF.

“…Maintaining balance in the upright position is a complex and continuous task in the daily life, and reciprocal effects between sleep and vestibular function have been objects of research 1–4 . Several animal and human studies have demonstrated that the vestibular system, in addition to postural control, plays a role in the regulation of heart rate, respiration, and blood pressure, as well as making some contribution to the sleep cycle 5–10 .…”

“…Dysfunctions in these organs could lead to disruption in the sleep–wake cycle 12 . Thus, it is possible that signals coming from the vestibular system are related to sleep regulation, as noted in actions such as walking, driving a car, and other movements that stimulate the vestibular system, and also help to induce sleep 3 . Furthermore, since changes in the autonomic functions, which include pupillary responses, heart rate, and blood pressure peaks, are characteristics of rapid eye movement (REM) sleep, oscillations in these functions are abolished in cases of vestibular nuclei lesions 13 .…”

Objective: To evaluate sleep behavior and its relation to otoneurological parameters in a group of patients with chronic unilateral vestibular hypofunction (UVH) without self-reported sleep disturbances when compared with healthy subjects serving as a control group (CG).Methods: Fifty-one patients affected by UVH underwent a retrospective clinical and instrumental otoneurological examination, a 1-week actigraphy sleep analysis, and a series of self-report and performance measures (SRM/PM). A CG of 60 genderand age-matched healthy subjects was also enrolled. A between-group analysis of variance was performed for each variable, while correlation analysis was performed in UVH patients between otoneurological, SRM/PM, and actigraphy measure scores.Results: When compared with CG subjects, UVH patients were found to be spending less time sleeping and taking more time to go from being fully awake to asleep, based on actigraphy-based sleep analysis. Also, SRM/PM depicted UVH patients to have poor sleep quality and to be more prone to an evening-type behavior. Correlations were found between vestibular-related functionality indexes and subjective sleep quality, as well as between longer disease duration and reduced sleep time.Conclusion: For the first time, a multiparametric sleep analysis was performed on a large population-based sample of chronic UVH patients. While a different pattern in sleep behavior was found, the cause is still unclear. Further research is needed to expand the extent of knowledge about sleep disruption in vestibular disorders.

“…5,6 It is known that the neurons that take part in the sleep stages are located in the pontine reticular formation and raphe nuclei, which are regions that also receive information for the otolithic organs. 7,8 Dysfunctions in these organs could lead to interruptions in the sleep-wake cycle. 8,9 Thus, it is possible that signals coming from the vestibular system are related with sleep regulation, as noted in actions such as walking, and riding a car as well as other movements that stimulate the vestibular system and help induce sleep.…”

Introduction Some studies have shown associations between sleep quality and dizziness. However, this association has not been investigated in teachers. Objective To verify a possible association between dizziness complaint and sleep quality in teachers. Methods Cross-sectional study developed with 96 school teachers (mean age of 47.8 ± 9.8 years). To assess dizziness, an audiological assessment was performed, which was the same one used in routine audiological care (Miller protocol). The dizziness handicap inventory (DHI) was applied to those individuals who reported dizziness. To evaluated sleep quality, the Pittsburgh sleep quality index was used. Results The prevalence of dizziness was 22.9% (n = 22). Of these, 77.3% (n = 17) were women, 63.6% (n = 14) demonstrated poor sleep quality, and 54.5% (n = 12) were young adults (27–48 years). In the comparison between the dizziness and the control groups, no statistically significant differences were found (p> 0.05). The analysis adjusted for the confounding variables showed a difference for men in the sleep efficiency variable (p = 0.043); young adults showed a statistically significant difference in the total score (p = 0.021) and total sleep time (p = 0.029). There was a moderate correlation between DHI and total time in bed (p = 0.036, r = 0.497) and DHI and sleep efficiency (p = 0.014; r = -0.582). Conclusion Dizziness influences the quality of sleep in teachers, especially that of the youngest and male patients. There was a moderate correlation between total time in bed, sleep efficiency, and DHI, demonstrating that sleep quality should be considered an important factor in the assessment and rehabilitation process of dizziness.
