Central retinal vein occlusion associated with hemodialysis
The American Journal of the Medical Sciences
|January 1, 1979
Summary
Central retinal vein occlusion (CRVO) is a rare complication in hemodialysis patients. This study observed three cases of CRVO in 15 patients, suggesting a potential link to hemodialysis-induced hypercoagulable states.
Area of Science:
- Ophthalmology
- Nephrology
- Hematology
Background:
- Central retinal vein occlusion (CRVO) is a serious ophthalmologic condition.
- CRVO is rarely reported in patients undergoing maintenance hemodialysis.
- Underlying conditions in the affected patients included lupus nephritis, Henoch-Schönlein purpura, and nephrosclerosis, along with moderate hypertension.
Purpose of the Study:
- To report and investigate unusual cases of CRVO in maintenance hemodialysis patients.
- To explore potential etiological factors for CRVO in this specific patient population.
Main Methods:
- Observational case series of 15 maintenance hemodialysis patients.
- Clinical assessment of visual acuity, funduscopic examination, and patient history.
- Review of underlying conditions and dialysis parameters.
Main Results:
- Three of 15 patients developed CRVO within a two-week period.
- Presenting symptom was impaired vision 24-36 hours post-dialysis.
- Findings included decreased visual acuity, retinal engorgement, hemorrhage, and disc edema, leading to vision loss in all affected eyes.
Conclusions:
- A hypercoagulable state, possibly due to a transient factor associated with hemodialysis, is a potential cause for these CRVO cases.
- Further research is needed to elucidate the exact mechanism linking hemodialysis to CRVO.
