Kayser Fleischer ring
The ring encircling the iris of the eye is known as ‘Kayser-Fleischer ring’. These are dark rings which are the result of copper deposition. This copper deposition occurs in patients suffering from liver related diseases. Found in descemet’s membrane and can extend into tabecular meshwork. It first appears as a crescent at top of the cornea. This ring for identification requires a slit-lamp examination in its early stage. These rings are considered as a sign of Wilson’s disease and may be a result of abnormalities in basal ganglia of the brain, liver cirrhosis, muscle rigidity and involuntary movements. Copper chelation can be used as a therapy.
This is Heterochromia Iridum. Kayser-fleischer rings are caused by copper deposition in Descemet’s membrane, with coloration visible at the corneoscleral-junction.
How can you tell, if it is Kayser-Fleischer ring or heterochromia iridis? Because these look pretty similar.
In heterochromia iridium eyes are not the same color and in kayser Fleischer ring patient suffers from deposition of cooper and liver disease. I can give you sure that this patient is kayser Fleischer ring.
This pic is not an example for Kayser-fleischer ring, it is a Heterochromia Iridum ..
