Fleischer ring is a medical condition characterized by the presence of a green or yellow-brown ring in the cornea, typically in individuals with keratoconus or Wilson's disease. The ring is composed of iron deposits in the peripheral corneal epithelium.
Causes[edit]
Fleischer rings are most commonly associated with keratoconus, a degenerative disorder of the eye in which the cornea assumes a conical shape. They can also occur in Wilson's disease, a rare inherited disorder that causes copper to accumulate in the liver, brain, and other vital organs.
Symptoms[edit]
The presence of a Fleischer ring does not typically cause any symptoms. However, the underlying conditions associated with Fleischer rings, such as keratoconus and Wilson's disease, can cause a variety of symptoms. In keratoconus, symptoms may include blurred vision, light sensitivity, and eye redness or swelling. In Wilson's disease, symptoms can range from fatigue and lack of appetite to jaundice, fluid buildup in the legs or abdomen, and uncontrolled movements or muscle stiffness.
Diagnosis[edit]
Fleischer rings can be detected during a routine eye examination. The ring is best seen with a slit lamp, a device that allows the doctor to examine the eye under high magnification. In some cases, the ring may be visible only with certain types of illumination.
Treatment[edit]
There is no specific treatment for Fleischer rings. Instead, treatment focuses on managing the underlying condition. For keratoconus, this may involve the use of corrective lenses or, in severe cases, corneal transplant. For Wilson's disease, treatment typically involves medications to reduce the amount of copper in the body.
