[Intraocular pulse fluctuations in pressure in neovascularization glaucoma in comparison to other forms of glaucoma (results of direct manometric measurements)].

With tonometric and tonographic measurements it is possible to detect and record oscillations which are synchronous with the intraocular pulse. These oscillations decrease with increasing IOP. In contrast, with direct manometric measurement, the amplitude of the intraocular pulse increases with increasing intraocular pressure. Therefore, in order to determine the intraocular pulse amplitude in patients, direct manometric measurements were performed on blind or almost blind eyes. Intraocular pressure was experimentally elevated by injecting fluid through a cannula into the anterior chamber, using a special Guyon syringe. The course of the drop in pressure and the amplitudes of the intraocular pulse were recorded with the Neuhaus apparatus and a light-spot pen. The most striking result was that in neovascular glaucomas there are excessive pulse amplitudes. The question whether the poor prognosis of neovascular glaucoma is associated with these intraocular pulsations is discussed.
