“…Information obtained in the present study can therefore only be transferred to the period of time between 7 am and midnight, the time when many patients usually go to bed. The dependence of IOP on body position (sitting versus supine) also limits the comparability of the results of our study with findings reported by other investigations which measured IOP in supine position during sleep 10,15,18. Thirdly, our results may be valid only for eyes without previous filtering surgery.…”

Treated secondary open-angle glaucoma eyes did not exhibit the normal day-and-night pressure profile which was usually shown in normal eyes and eyes treated for other types of chronic open-angle glaucoma. The day-and-night IOP amplitude in absolute terms is highest in secondary open-angle glaucoma. In relative terms, the IOP amplitude did not vary significantly between the various types of chronic open-angle glaucoma. Inter-eye IOP differences were significantly (P < 0.001) smaller than the IOP profile amplitude.

“…There are reports that found greater fluctuation and range in intraocular pressure in individuals with glaucoma compared to healthy control individuals [39, 40]. Studies by Liu and colleagues [38] found that the larger the diurnal variation and fluctuation of intraocular pressure, the greater the risk for structural damage due to glaucoma.…”

Imaging through the visual system in Alzheimer's disease, with the technology currently in widespread use for the diagnosis and management of eye disease such as glaucoma and macular degeneration, is proving to be promising. In vivo cross-section imaging during an annual comprehensive eye exam has been available for a decade for glaucoma and macular degeneration, and this same imaging, using Optical Coherence Tomography, has been demonstrated to show deficits specific to AD and mild cognitive impairment. These deficits are in the form of nerve fiber layer tissue drop out in the retina and optic nerve. The retrograde loss of nerve fiber layer tissue in the retina and optic nerve may be an early biomarker of AD, and these deficits in the nerve fiber layer of the retina and optic nerve may be the earliest sign of AD, even prior to damage to the hippocampal region that impacts memory.

“…While nocturnal IOP elevation may play a significant role in glaucoma pathogenesis [1–3, 30, 31], it is frequently undetected in clinical practice because routine IOP examinations are conducted during the daytime. Furthermore, glaucomatous VF progression has been associated with nocturnal events such as diminished nocturnal ocular perfusion pressure owing to low systemic blood pressure (BP) and/or nocturnal IOP elevation in the presence of normal daytime IOP [32–35].…”

ObjectiveTo characterize the 24-h habitual-position intraocular pressure (IOP) patterns of optic disc phenotypes (ODPs) in untreated normal-tension glaucoma (NTG) and the relationships between nocturnal IOP elevation and various clinical factors.DesignProspective, cross-sectional, observational study.MethodsEighty-two NTG patients with focal ischemic (FI) ODP and 82 age- and disease severity-matched NTG patients with myopic glaucomatous (MG) ODP were recruited prospectively over 3 years. The IOP was recorded 11 times over a 24-hour (h) period by a single ophthalmologist using a hand-held tonometer (TonoPen®XL). A cosinor model was used to describe the 24-h IOP rhythm. Associations between nocturnal IOP elevation and both ocular and demographic variables were evaluated using the generalized estimating equation (GEE).ResultsMean habitual-position IOP was significantly higher during nighttime than daytime in the FI group (16.44 vs. 14.23 mmHg, P < 0.001), but not in the MG group (15.91 vs. 15.70 mmHg, P = 0.82). The FI group also exhibited a significantly higher peak IOP during sleeping hours (P = 0.01) and lower trough IOP during the 24-h period than the MG group (P < 0.01). The MG group showed a significantly higher peak IOP during waking hours than the FI group (P < 0.01). Therefore, 24-h IOP fluctuation range was significantly higher in the FI group than the MG group (P = 0.013). In the FI group, peak habitual-position IOP and the highest frequency of IOP peaks occurred during sleeping hours (12 AM–6 AM). By contrast, IOP peaks in the MG group occurred during morning hours (8 AM–12 PM). The FI group showed an overall nocturnal acrophase in habitual-position IOP, with 45 patients (54.9%) having a nocturnal acrophase; 10 (12.2%), a diurnal acrophase; and 27 (32.9%), no evident acrophase. By contrast, the MG group showed no evident peak in habitual-position IOP, with 9 patients (10.9%) having a nocturnal acrophase; 43 (52.4%), a diurnal acrophase; and 30 (36.6%), no evident acrophase. In multivariate modeling using the GEE, ODP (P < 0.001) and spherical equivalent (SE, P = 0.001) were independently associated with nocturnal IOP elevation.ConclusionsBased on 24-h habitual-position IOP data, FI is associated with significant nocturnal IOP elevation, while no such nocturnal IOP elevation is observed in MG ODP. In untreated NTG, there are also significant differences in the 24-h IOP pattern between FI and MG ODPs.
