Annals of Ophthalmology
|March 1, 1990
Summary
Amyloidosis can cause unexplained vitreous opacification, delaying diagnosis. Early consideration and diagnostic tools like conjunctival biopsy are crucial for managing this rare ocular condition.
Area of Science:
- Ophthalmology
- Neurology
- Pathology
Background:
- Bilateral vitreous opacification presents a diagnostic challenge.
- Peripheral neuropathy can be an early indicator of systemic disease.
Observation:
- A 72-year-old man with bilateral vitreous opacification and mild peripheral neuropathy underwent multiple vitrectomies.
- Diagnosis of amyloidosis was confirmed post-second vitrectomy via Congo red staining of aspirate.
Findings:
- Amyloid deposition in the vitreous humor caused the opacification.
- Delayed diagnosis was linked to underrecognizing the significance of peripheral neuropathy.
Implications:
- Consider amyloidosis in patients with unexplained vitreous infiltration.
- Conjunctival biopsy may aid diagnosis.
- Surgical removal of vitreous may reduce reopacification incidence.
