Munson's sign is a V-shaped indentation observed in the lower eyelid when the patient's gaze is directed downwards. The medical sign is characteristic of advanced cases of keratoconus and is caused by the cone-shaped cornea pressing down into the eyelid.
Other clinical signs of keratoconus will normally have presented themselves long before Munson's sign becomes apparent, [46] and so this finding, though a classic sign of the disease, tends not to be of primary diagnostic importance.
However, it may not be as specific as corneal pachymetry, because corneal topography only evaluates the degree and distribution of surface irregularities on the cornea, not the thickness of the cornea. [5] Corneal topography may show a "crab claw-like" appearance, a finding that is seen in both keratoconus and in pellucid marginal degeneration.
Keratoconus, a progressive, noninflammatory, bilateral, asymmetric disease, characterized by paraxial stromal thinning and weakening that leads to corneal surface distortion. [2] Keratoglobus, a rare noninflammatory corneal thinning disorder, characterised by generalised thinning and globular protrusion of the cornea. [3]
Fleischer rings are pigmented rings in the peripheral cornea, resulting from iron deposition [2] in basal epithelial cells, in the form of hemosiderin. [3] They are usually yellowish to dark-brown, and may be complete or broken. [4] The rings are best seen using the slit lamp under cobalt blue filter. [4] They are named for Bruno Fleischer. [5]
Corneal hydrops is an uncommon complication seen in people with advanced keratoconus or other corneal ectatic disorders, [1] and is characterized by stromal edema due to leakage of aqueous humor through a tear in Descemet's membrane. [2]
