title: [Disorders of ion balance in intraocular liquid at patients with senile and complicated cataracts].
abstract: Nowadays the regional mechanisms underlying disorders of drainage function and the increased intraocular pressure at various types of glaucoma are the subject of wide discussion in ophthalmology. In the specified aspect and to this day there are no comprehensive data concerning the roles of the broken ion exchange in hydrostatic systems of an eye, in particular, potassium-sodium pomp in mechanisms of ophtalmohypertension induction. The object of research was intraocular liquid of patients with the senile and complicated cataracts proceeding on the background of anterior open-angle glaucoma, pseudoexfoliative glaucoma, cataracts proceeding on the background of idiopathic hypertension, diabetes and the previous trauma. Samples of intraocular liquid were subjected to ion-selective analysis for definition of sodium, calcium and potassium ions content that was expressed in mmol/L. The analyzer Kone-microlyte (Finland) was used at definition of ionic composition. Program coefficient was defined using the refractometer of Shibuya Optical CO (Japan). The results were subjected to the statistical analysis using Student's criteria, with application of computer program SPSS version 13 ANOVA. At the cataract proceeding on the background of anterior open-angle glaucoma and pseudoexfoliative glaucoma in intraocular liquid relatively high indexes of the diffraction index and level of sodium and calcium ions were registered on the background of potassium ions decreased content. At the complicated cataracts: the cataract proceeding on the background of open-angle glaucoma and pseudoexfoliative cataract, in intraocular liquid the alterations in its protein and ionic composition are found to be considered as the risk factors resulting in disorders of drainage function and increase of intraocular pressures.
