Perilimbal Suction Cup Technique Combined With Tonography or Bulbar‐pressure Test

Abstract

T h e aqueous humor production is suppressed during the perilimbal pressure cup technique. This effect can be diminished if the intraocular pressure prior to the test is decreased by tonography o r bulbar-pressure test. When such combined procedure was employed the suction cup technique showed a 1.5-fold increase of the values of aqueous inflow in 91 normal eyes and a 1.3-fold increase in 25 glaucomatous eyes. I n another series of 243 normal eyes, 113 eyes with open angle glaucoma and 91 eyes with chronic closed angle glaucoma, either suction cup test or combined technique was performed. T h e mean values of aqueous inflow were significantly greater if tonography or bulbar-pressure technique was performed prior to the suction cup test.
