Summary
Fluid overload in end-stage renal disease can rarely cause vision loss. Optical coherence tomography confirmed retinal edema resolution after managing fluid status.
Area of Science:
- Nephrology
- Ophthalmology
Background:
- Fluid overload is a common complication in end-stage renal disease (ESRD).
- Typical signs include edema, shortness of breath, and ascites.
- Systemic fluid imbalance can rarely manifest as vision loss.
Observation:
- A case report detailing vision loss in an ESRD patient.
- The vision loss was attributed to retinal edema.
- Optical coherence tomography (OCT) was used for diagnosis and monitoring.
Findings:
- The patient experienced vision loss secondary to fluid overload.
- Retinal edema was identified as the cause of vision impairment.
- Successful management of fluid overload led to vision recovery.
Implications:
- Highlights an unusual presentation of fluid overload in ESRD.
- Emphasizes the importance of considering ophthalmologic evaluation in fluid overload.
- Demonstrates the utility of OCT in diagnosing and managing retinal edema related to fluid status.
