Optic nerve head behavior in Posner-Schlossman syndrome.
PURPOSE: To analyze the effect of glaucomatocyclitic crisis on the optic nerve head, as well as its consequent structural and hemodynamic changes. To evaluate the surgical indication for Posner-Schlossman syndrome.
MATERIALS AND METHODS: Four Posner-Schlossman syndrome cases were evaluated for an analysis of the phenomena occurring in the optic disc by means of retinal confocal tomography and Scanning Laser Doppler Flowmetry, and their correlation with visual function as measured with automated computerized perimetry. In all cases the images were obtained in the mediate period after the attack, while in case 1, measurements were performed in the immediate and mediate periods before, during and after the attack.
RESULTS: Significant differences were found between optic nerve head parameters and retinal flow measurements in the different phases evaluated. No permanent optic nerve head damage was demonstrated in any of the cases studied, except for case 4 (Posner-Schlossman syndrome associated with traumatic glaucoma). All the variables analyzed returned to normal values after remission of the acute rise in intraocular pressure.
CONCLUSIONS: During the attacks of ocular hypertension the optic nerve head experiences significant morphologic changes and hemodynamic variations; nevertheless since they are transient, they fail to cause permanent damage. There was only one case, in which there was optic disc damage and visual field loss. It can be concluded that surgery should be restricted to those cases with severe and disabling symptoms (relative surgical indication) or to cases with progressive optic neuropathy with visual field loss, when the syndrome is associated with glaucoma (absolute surgical indication).
