Chronic Kidney Diseases, Hemolysis
Conditions
Brief summary
To evaluate the effect of hemodialysis on various ophthalmologic parameters in patients with end-stage kidney disease (ESRD).
Detailed description
Subjects: patients with ESRD undergoing hemodialysis at the Dialysis Center of Hanyang Guri Hospital Ocular parameters: visual acuity, intraocular pressure, axial length, OCT Other systemic parameters: body weight, ultrafiltration volume, and systolic/diastolic blood pressure All measurements were performed near the dialysis center. Measurements were performed on Monday (for patients who underwent dialysis sessions on Monday, Wednesday, and Friday) or Tuesday (for patients who underwent dialysis sessions on Tuesday, Thursday, and Saturday. All parameters were measured before and after the hemodialysis.
Interventions
ophthalmologic exams such as vision, intraocular pressure, axial length and optical coherence tomography
