The characteristic of intraocular pressure dynamic change in patients with glaucomatocyclitic crisis.

Abstract

To investigate the characteristic of intraocular pressure (IOP) dynamic change from episode to intermittent period in patients with Posner-Schlossman syndrome (PSS). Seventeen cases of typical PSS were collected in this study. Both their random IOP in episodes/intermittent period and 24-h IOP in intermittent period were measured. The mean IOP as well as the peak and the valley value of 24-h IOP were calculated. Those data were statistically analyzed. The IOP in affected eye in episodes is higher than that of the contralateral eye statistically; while in intermittent period the mean IOP (p = 0.001), the peak (p = 0.029) and the valley (p = 0.004) value of 24-h IOP in affected eye are statistically different with that of the contralateral eye. All of these parameters of the affected eye in intermittent period are lower than that of the contralateral eye obviously. The dynamic observations of IOP in episodes and intermittent period confirmed the IOP crossover phenomenon inpatients with typical PSS and this observation may be important in the differential diagnosis of PSS.
