A fall in intraocular pressure in the contralateral undisturbed eye as a result of massage and trauma has been known since 1878 when Pagestecher¹ described his observations. The term "ophthalmotonic consensual reaction" appears to have been coined by Weekers² in 1924.

The consensual fall in intraocular pressure accompanying tonography is well annotated,^3-6,11 and its importance lies in the fact that the change in ocular dynamics which must occur to produce it may lend itself to study and analysis of the neurovascular reflexes subservient to the homeostatic mechanisms maintaining normal intraocular pressure. The literature suggests that the consensual fall occurs in most people and is of the order of 1-4 mm. Hg.³ The exact mechanism is not clearly worked out, but in animals Prijot and Stone⁴ found a decrease in flow of aqueous humor in the presence of unchanged facility of outflow, scleral rigidity, and constant . . .
