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.
A highly pronounced cone can create a V-shaped indentation in the lower eyelid when the person's gaze is directed downwards, known as Munson's sign. [14] 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 ...
Corneal topography may show a "crab claw-like" appearance, a finding that is seen in both keratoconus and in pellucid marginal degeneration. Thus, if corneal topography is used for diagnosis, it should be in conjunction with clinical findings of peripheral, inferior corneal thinning. [8]
In progress, but mostly complete. (Would be nice to know who coined the term keratoconus.) Consider changing the title of "Diagnosis" to "Signs" or "Signs and Diagnosis", then merge the section entitled "Possible complications" with it. Done. Consider adding mention of Munson's sign in signs/diagnosis section. Done
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.
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]

In 1748 he became one of the first to document the eye disorder now known as keratoconus. His surviving works are now to be found in the form of theses by his students. He obtained his Lic. Med. degree in 1722 at the University of Tübingen. Mauchart also studied for two years in Paris from 1718-1720 under the oculist Woolhouse.
