Changes in intraocular pressure during hemodialysis and hemofiltration

: The authors compare changes of intraocular pressure during haemodialysis and haemofiltration in six patients. The measurements were made with the patients in a sitting position, using an applanation tonometer according to Perkins, during both operations every hour. A rise to 25 torr was recorded in one patient repeatedly during haemofiltration in both eyes one hour after the blood pressure had risen to 220/120 and 210/110. In the other patients the variations of the intraocular pressure were within the physiological range. Based on data in the literature the authors recommend the use of haemofiltration in patients with glaucoma and after eye surgery.
