A functional vagotomy induced by unilateral forced right nostril breathing decreases intraocular pressure in open and closed angle glaucoma.

Abstract

There is evidence of the central regulation of intraocular pressure, and it has been suggested

Effect of unilateral forced nostril breathing on tonic accommodation and intraocular pressure

“…The percentage of change in IOP reported here is smaller than previous studies where a reduction of 25 % was reported [3,4]. UFNB appeared to have a greater effect on IOP than on accommodation (assessed using TA).…”

“…Previous studies have shown that right UFNB produces a significant reduction in intraocular pressure (IOP) in both normal subjects [4,15,20] and glaucoma patients [3]. The reduction in IOP mediated by right UFNB (i. e. sympathetic activation) was found to be as high as 25 % (4.6 mmHg) in both normal subjects and glaucoma patients [3,4].…”

“…The reduction in IOP mediated by right UFNB (i. e. sympathetic activation) was found to be as high as 25 % (4.6 mmHg) in both normal subjects and glaucoma patients [3,4]. Other ocular characteristics or physiological processes that may also be manipulated by UFNB include blink rate [2], pupil size (i. e. degree of pupillary dilatation/miosis) and pupil cycle time [3].…”

Effect of left & right nostril breathing on R-R interval among adult males – A cross-sectional study

“…Alternate nostril breathing has been shown to affect the basal sympathetic tone [3], vagal tone [23], resting heart rate [24], blood pressure [24][25], bronchial tone [26], IQ and social adaptation parameters [27], reaction times [28], glycemic control and lipid profile. [29] [30] Forced single nostril breathing has also been shown to have similar effects, namely on verbal and spatial performances [31], behavior [32], blink rates [11], intra-ocular pressure [12]- [16], respiratory rate [17], blood pressure [17] and heart rate. [18]- [22] The effects of single nostril breathing on HRV has also been studied.…”

“…[9] The short-term effects of alternate nostril breathing maneuvers have been reported as increased galvanic skin resistance, decreased oxygen consumption, decreased heart rate, decreased blood pressure and increased amplitude of theta waves. [10] Practiced single nostril breathing maneuvers have been reported to have various other effects, such as on blink rates [11], intraocular pressure [12]- [16], respiratory rate [17], diastolic blood pressure [17] and heart rate. [18]- [22] The literature available on the immediate effects of forced single nostril breathing is relatively less.…”
