[Effect of serum osmolarity, arterial blood pressure and volume loss on IOP during hemodialysis, hemofiltration and simultaneous hemofiltration/hemodialysis (author's transl)].

In 29 patients suffering from chronic renal failure intraocular pressure was measured during different therapeutic regimens. Conventional hemodialysis (principle of transport diffusion, n = 15) led to an increase in IOP after one hours treatment. In individuals complaining of headaches during dialysis a marked increase in IOP was observed indicating a disequilibrium syndrome. Hemofiltration is characterized by mass transfer and exchange of plasma water. When this treatment was applied to 6 patients IOP was elevated during the second hour. Simultaneous hemofiltration/hemodialysis (n = 8) had no influence on IOP behaviour. Statistically there was no correlation between the behaviour of serum osmolarity, arterial blood pressure, loss of body weight and IOP.
