Summary
Primary localized conjunctival amyloidosis can present unusually with corneal whorl-like opacities. This case highlights a rare manifestation of conjunctival amyloidosis involving the cornea.
Area of Science:
- Ophthalmology
- Pathology
Background:
- Primary localized conjunctival amyloidosis (PLCA) typically affects the conjunctival fornix and lids.
- Corneal involvement in PLCA is uncommon, with distinct clinical presentations.
Observation:
- A 35-year-old male presented with bilateral corneal whorl-like opacity patterns.
- The patient was diagnosed with primary localized conjunctival amyloidosis.
Findings:
- Histopathology confirmed amyloid deposition in the conjunctiva and limbus.
- Negative genetic testing ruled out gelatinous drop-like corneal dystrophy.
- Systemic workup excluded secondary systemic amyloidosis.
Implications:
- This case expands the known clinical spectrum of primary localized conjunctival amyloidosis.
- Corneal opacities can be an initial presenting sign of PLCA.
- Early recognition is crucial for appropriate diagnosis and management.

Amyloid Fibrils
11.5K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Glaucoma: Overview
1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
