Summary
Maintenance hemodialysis (HD) patients show reduced retinal light sensitivity, particularly those with hypertensive retinopathy. Age and HD duration did not correlate with this visual field loss.
Area of Science:
- Ophthalmology
- Nephrology
- Medical Imaging
Background:
- Chronic renal failure (CRF) patients undergoing maintenance hemodialysis (HD) may experience ocular complications.
- Retinal light sensitivity is a key indicator of visual function.
Purpose of the Study:
- To compare retinal light sensitivity in HD patients versus healthy controls.
- To investigate correlations between visual field loss and patient factors (age, HD duration, hypertensive retinopathy).
Main Methods:
- Visual field testing using the Humphrey field analyser (C-30-2 program) was performed on 50 eyes of 25 HD patients and 30 eyes of 15 controls.
- Statistical analysis was used to assess differences in retinal light sensitivity and correlations.
Main Results:
- 36% of HD patients exhibited significantly reduced retinal light sensitivity (MD, PSD, CPSD P<5%), while controls had normal values.
- No correlation was found between reduced sensitivity and patient age or HD duration.
- HD patients with hypertensive retinopathy showed significantly greater reduction in retinal light sensitivity.
Conclusions:
- A significant proportion of HD patients have reduced retinal light sensitivity, even without evident arteriolar occlusion.
- Hypertensive retinopathy is a significant risk factor for reduced retinal light sensitivity in HD patients.
