Pseudogerontoxon in VKC
-Pseudogerontoxon is a lesion that resembles a small segment of arcus senilis or gerontoxon and is seen in many individuals with limbal vernal or atopic keratoconjunctivitis
-Paralimbal band of lipid deposits in superficial stroma, appearing as an arcuate, whitish band near the superior limbus, mimicking arcus senilis
-It results from chronic, severe peripheral corneal inflammation, serving as a key marker of prior allergic disease, particularly in children and young adults with limbal VKC
-Frequently seen in combination with other signs of chronic inflammation, such as superior tarsal papillae (giant papillae), Trantas dots, and peripheral corneal scarring
APPEARANCE:
-White, crescent-shaped band, often found in the mid-peripheral cornea, usually adjacent to areas of past active inflammation
-Caused by chronic vascular permeability in the inflamed limbus, leading to lipid accumulation and corneal structural remodeling
-Often the only remaining evidence of previous, chronic allergic eye disease, particularly when the disease is in a quiescent stage
-No specific management required
