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 ...
The early stages of pellucid marginal degeneration may also be managed with soft contact lenses. [1] Success has been shown with the use of rigid gas permeable contact lenses combined with over-refraction. People wearing contacts don't report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the ...
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 in itself is a pattern of the entire cornea, therefore every measurement just focusing on one layer, might not be enough for a state of the art diagnosis. Especially early cases of keratoconus might be missed by a plain topographic measurement, which is critical if refractive surgery is being considered. [ 7 ]
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]
According to Know Your Lemons, a nonprofit global organization that focuses on making information about breast cancer warning signs and detection methods accessible, a hard lump is a common sign ...
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]
