Ocular abnormalities associated with advanced kidney disease and hemodialysis

Area of Science:

• Ophthalmology
• Nephrology
• Internal Medicine

Background:

• Chronic hemodialysis patients experience complex physiological changes due to uremia and the dialysis procedure.
• These changes can significantly affect multiple organ systems, including the visual system.
• Pre-existing eye conditions may be exacerbated by the hemodialysis process.

Purpose of the Study:

• To review common ocular diseases in patients undergoing chronic hemodialysis.
• To elucidate the impact of the uremic state on the visual system.
• To analyze how the hemodialysis procedure influences the progression of eye diseases and vision.

Main Methods:

• Literature review of studies focusing on hemodialysis patients and ophthalmological conditions.
• Analysis of the pathophysiological mechanisms linking uremia, hemodialysis, and visual impairment.
• Synthesis of current knowledge on the management and monitoring of eye diseases in this population.

Main Results:

• Uremia and hemodialysis are associated with an increased prevalence and severity of certain eye diseases.
• Diabetic retinopathy and glaucoma are frequently observed and can be worsened by dialysis.
• Fluid shifts and electrolyte imbalances during dialysis can acutely affect intraocular pressure and vision.

Conclusions:

• Patients on chronic hemodialysis require careful ophthalmological monitoring.
• Understanding the interplay between uremia, dialysis, and eye disease is crucial for preserving vision.
• Further research is needed to optimize eye care strategies for hemodialysis patients.
