RESUMO
PURPOSE: To evaluate intraocular pressure (IOP) change through hemodialysis and examine other factors to affect IOP change in patients treated with hemodialysis. DESIGN: Prospective, observational case series. METHODS: IOP, blood pressure, and plasma colloid osmotic pressure (COP) were measured in 188 eyes of 95 patients receiving hemodialysis in Nantan General Hospital. RESULTS: IOP significantly decreased after hemodialysis (P = 0.006). Body weight, systolic and diastolic blood pressure also decreased significantly (P < 0.001). COP significantly increased (P < 0.001). Change in IOP correlated negatively with COP change (OD; r = -0.196, OS; r = -0.339) and positively with change in body weight (OD; r = -0.278, OS; r = -0.357). IOP tended to increase after hemodialysis in patients receiving hemodialysis for more than 12 years. CONCLUSIONS: IOP decrease during hemodialysis may be due to COP increase. Patients receiving hemodialysis for a long time are more likely to show IOP increase after hemodialysis.
