H18.041
Kayser-Fleischer ring, right eye
Clinical Classification Guidelines
Medical Intelligence & Overview
A Kayser-Fleischer ring is a colored ring that appears around the cornea of the eye. When located in the right eye, it is specified as H18.041. This ring is often associated with Wilson's disease, a genetic disorder where excess copper builds up in the body. Recognizing this ring can be an important part of diagnosing underlying health issues, particularly those affecting copper metabolism.
Causes & Symptoms
Clinical Causes: Wilson's disease, a genetic disorder leading to copper accumulation Excess copper deposits in Descemet's membrane of the cornea Rarely, other conditions involving abnormal copper metabolism
Key Symptoms: Presence of a colored ring around the cornea, typically green or golden-brown No pain or vision changes directly caused by the ring Potential signs of Wilson's disease, such as liver issues, neurological symptoms, or psychiatric problems
Diagnostic & Treatment
Diagnosis Path: Diagnosis often involves an eye examination using slit-lamp microscopy to detect the characteristic ring. Blood tests to measure copper levels and genetic testing may be used to confirm Wilson's disease. The identification of a Kayser-Fleischer ring can be a crucial clue supporting the diagnosis.
Treatment Protocols: Treatment focuses on managing the underlying condition, primarily Wilson's disease. This may include medications like chelating agents to remove excess copper, zinc therapy to block copper absorption, and dietary adjustments. Regular eye examinations can monitor the presence and progression of the ring, but its removal is typically not possible as it reflects systemic copper buildup rather than a treatable eye condition.
