Ring staphyloma, bilateral

This code describes a bilateral ring-shaped ectasia or bulging of the sclera, typically occurring around the limbus. This thinning and protrusion of the sclera can lead to visual disturbances and is often associated with high myopia or other ocular conditions.

Use this code when documentation specifies ring staphyloma affecting both eyes. This diagnosis is typically made during an ophthalmological examination, often involving slit-lamp biomicroscopy and imaging studies.

• Ensure documentation explicitly states "bilateral" to support this code.
• Do not confuse with other forms of staphyloma (e.g., equatorial, posterior) or other scleral thinning disorders.
• Code any underlying or associated conditions, such as high myopia or glaucoma, as additional diagnoses.
