[Thésaurus HELB]:Optique:pression intraoculaireRésumé : SIGNIFICANCE Precise measurement of intraocular pressure (IOP) is essential when diagnosing and managing glaucoma. We compared the IOP readings of three different tonometers and analyzed agreement among tonometers in eyes with high IOPs.
PURPOSE The purpose of this study was to compare the IOP readings obtained using a Goldmann applanation tonometer (GAT), a rebound tonometer (RT), and a Tono-Pen (TP) in angle-closure eyes with elevated IOP before and after medical IOP-lowering therapy.
METHODS Twenty-five eyes of 25 patients with angle closure and IOPs of greater than 30 mmHg were enrolled. Intraocular pressure was measured using RT (iCare Pro), TP (Tono-Pen XL), and GAT before and after medical treatment. The mean IOP readings of the tonometers were compared before and after treatment. The agreement among the tonometers was assessed via Bland-Altman analysis.
RESULTS The measurements from 22 eyes of 22 patients were suitable for statistical analyses. Before medical treatment, the mean TP-IOP was significantly lower than the mean GAT-IOP (44.0 ± 10.3 vs. 50.4 ± 8.9 mmHg, respectively; P < .001), but no significant difference was evident between the RT-IOP and the GAT-IOP (50.8 ± 10.9 vs. 50.4 ± 8.9 mmHg, respectively; P = .79). After IOP-lowering treatment, the mean GAT-IOP (14.9 ± 4.7 mmHg) did not differ from either the mean RT-IOP (15.6 ± 4.4 mmHg) or the mean TP-IOP (15.4 ± 5.0 mmHg; P = .05 and P = .18, respectively). The random measurement error among tonometers was greater for high IOP readings.
CONCLUSIONS Compared with RT or GAT, TP underestimated IOP in angle-closure eyes with a GAT-IOP of greater than 30 mmHg. Intraocular pressure reading agreement among the three tonometers was lower in eyes with high IOP.

[Thésaurus HELB]:Optique:pression intraoculaireRésumé : SIGNIFICANCE Eyes with primary angle-closure disease showed higher intraocular pressure (IOP) in the recumbent postures including supine and lateral decubitus (LD) positions compared with the sitting position.
PURPOSE The purpose of this study was to investigate the effects of different body postures on the IOP in eyes with primary angle-closure suspect (PACS), primary angle closure (PAC), or primary angle-closure glaucoma (PACG).
METHODS This is a comparative case series of 31 patients with bilateral PAC disease, such as PACS, PAC, and PACG. The IOP was measured using Tonopen AVIA in sitting, supine, and right or left LD positions. Patients were instructed to rest their heads on the pillows in supine and LD positions. The eye on the lower side in the LD position was called dependent eye. The main outcome was the difference in IOP among different body postures.
RESULTS Among the 62 eyes (31 patients), PACG, PAC, and PACS were noted in 44, 12, and 6 eyes, respectively. The IOP was not significantly different between the two eyes in sitting and supine positions, whereas the IOP was significantly higher in the dependent eye than in the nondependent eye in LD positions. Compared with that measured in the supine position, IOP differences of the dependent eye were higher than those of the nondependent eye when measured in LD position (right LD vs. supine, P = .02; left LD vs. supine, P = .01). In addition, when the study patients were divided into three groups according to their diagnosis, no significant differences were observed in the IOPs and IOP differences among the three groups.
CONCLUSIONS Posture-induced IOP changes were comparable among eyes with PACS, PAC, and PACG.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]SommeilRésumé : SIGNIFICANCE In side-sleeping open-angle glaucoma (OAG) patients, eyes that showed progression exhibited a greater intraocular pressure (IOP) elevation when subjects were rested in the lateral decubitus (LD) posture on the ipsilateral side compared with those eyes that did not progress.
PURPOSE The purposes of this study were to investigate whether lying in the LD position for an extended period affects IOP in side-sleeping patients with OAG when rested on their own pillow and to compare posture-induced IOP variations between eyes with recent glaucomatous progression and those without.
METHODS Twenty-eight bilateral OAG patients who reported a preference for side sleeping were included. We measured IOP in both eyes, with the patient in the sitting and supine positions, 5 and 30 minutes after they had been in the right or left LD position (depending on their sleeping habits) and 5 minutes after they had returned to the supine position. While in the recumbent postures, the patients rested on their own pillows from home. The patients were divided into the correspondence and noncorrespondence subgroups, based on whether the laterality of the progressed eye corresponded with their habitual sleeping side.
RESULTS The IOP of the lower-sided eye increased further (+1.6 ± 1.8 mmHg; P < .001) when the LD posture was maintained for an additional 25 minutes. Such time-dependent IOP elevation in the dependent eye was greater in patients whose LD posture corresponded with glaucoma progression (+2.5 ± 1.7 mmHg) than in those who showed no correspondence or no glaucoma progression (+1.0 ± 1.6 mmHg; P = .03).
CONCLUSIONS Compared with nonprogressed eyes, progressed eyes exhibited a greater IOP elevation when the side-sleeping patients with OAG were rested in the LD posture on the ipsilateral side.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
