“…Such posture-induced IOP rise has been associated with progression of glaucomatous damage. 21,22,25 Some researchers studied the effect of sleeping in a head-up position using a wedge pillow in glaucoma patients 26,27 and healthy subjects, 27 and they demonstrated reduction of mean IOP by 1.5-3.2 mm Hg in the head-up position compared with the flat position. However, keeping the head up can be achieved by other methods such as using multiple pillows (MP) or raising the head of the bed.…”

Purpose To evaluate the effects of different methods of head elevation on intraocular pressure (IOP) in healthy young subjects. Methods Twenty-four healthy young Korean subjects were included in this prospective observational study. The IOP measurements were taken with the subjects in the sitting position and in the supine positions with the head flat and 301 up using two different methods: (1) raising the bed head and (2) using multiple pillows. IOP was measured using Tonopen AVIA in both eyes 10 min after assuming each position in a randomized sequence. The Wilcoxon signed-rank test was used to compare the IOP by changing the methods of head elevation. Results Mean IOP of both eyes when sitting was lower than that measured in the supine position with head flat (P ¼ 0.001). Compared with that measured in the supine position with head flat, the mean IOP was lower when measured in the supine position with the head kept 30 1 up by bed head elevation (P ¼ 0.001), whereas the mean IOP was not significantly different when measured in the supine position with the head elevated using multiple pillows (right eye, P ¼ 0.061; left eye, P ¼ 0.089). Conclusion In normal subjects, IOP was lower when measured in the supine position with the head kept up by the bed head elevation compared with that measured when lying flat. However, such head-up positioninduced IOP reduction was not found when the head was kept up using multiple pillows. These findings suggest that elevating the head using multiple pillows may not help to reduce IOP in the supine posture.

“…In a previous study,13 we reported that sleeping with the head elevated by 30° significantly lowered IOP in 35% of patients with progressive glaucoma compared with sleeping flat. To date, circadian IOP studies have required wakening the patient to measure the IOP at night.…”

“…It is unknown how awakening subjects influences IOP. Thus, we repeated our previous study13 using a telemetric contact lens sensor (CLS) that allows recording a 24-hour IOP-related pattern without having to waken the patient for pressure measurements.…”

Estudio comparativo de la determinación de la fluctuación de la presión intraocular, entre curva tensional horaria, prueba de sobrecarga hídrica y el método de estimación de la presión intraocular (Borrone), en pacientes con glaucoma primario de ángulo abierto en un hospital de concentración Recibido el 2 de julio de 2014; aceptado el 25 de noviembre de 2014 Disponible en Internet el 18 de febrero de 2015 PALABRAS CLAVE Curva horaria; Fluctuación presión intraocular; Borrone; Sobrecarga hídrica ResumenObjetivos: Evaluar los resultados de las pruebas de sobrecarga hídrica (SH) y estimación de presión intraocular o prueba de Borrone, en pacientes con glaucoma primario de ángulo abierto comparándolos con el estudio de curva tensional horaria. Material y método: A un mismo grupo de pacientes con diagnóstico de glaucoma primario de ángulo abierto se les realizó curva tensional horaria y se compararon los resultados de variabilidad de la presión intraocular con los obtenidos mediante la prueba de sobrecarga hídrica y con la prueba de Borrone. Resultados: La variación promedio de la presión intraocular en la curva horaria tensional fue de 4.05 ± 1.57 mmHg, en la prueba de SH fue de 3.55 ± 1.5 mmHg y en el método de Borrone de 2.55 ± 2.83 mmHg. La diferencia entre la variación medida con curva diurna y Borrone fue estadísticamente significativa (p = 0.025). La diferencia entre la variación medida con la curva * Autor para correspondencia.

Comparative study of the intraocular pressure fluctuations between the 24 hr tensional curve, Borrone test and water drinking test in patients with primary open glaucoma in Mexico AbstractObjetives: To evaluate de results of the water drinking test and Borrone test in patients with primary open angle glaucoma, comparing it with 24 hr tensional curve. Material and methods: To the same group of patients a 24 hr tensional curve was perfomed and the results were compared with the Borrone test and the water drinking test. Results: The average of intraocular pressure fluctuation was 4.05 ± 1.57 mmHg in the 24 hr tensional curve, for the water drinking test was 3.55 ± 1.5 mmHg and for Borrone test was 2.55 ± 2.83 mmHg. The difference of the results between the 24 hr tensional curve and Borrone test were statistically significant. The difference of the results between the 24 hr tensional curve and water drinking test were not statistically significant. We observed just a 40% of concordance between both the Borrone test and water drinking test with the 24 hr tensional curve.Conclusions: In the present study the Borrone test and the water drinking test obtained a low correlation with the 24 hr tensional curve which is considered the gold standard.
