Localized anterior staphyloma, bilateral

This code describes a condition where there is a localized bulging or ectasia of the anterior sclera, often involving the cornea or limbus, affecting both eyes. This protrusion is typically thinned and weakened, allowing the underlying uveal tissue to show through. It represents a structural abnormality of the anterior segment of the eye.

Use this code when documentation explicitly states "localized anterior staphyloma" and specifies that the condition is present in both the right and left eyes. This diagnosis is often made during an ophthalmological examination revealing the characteristic thinning and outward bulging of the anterior ocular wall.

• Ensure documentation specifies "anterior" and "localized" to differentiate from other types of staphyloma.
• Verify laterality; this code is specifically for bilateral involvement.
• Do not confuse with corneal ectasia or keratoconus unless the staphyloma is explicitly documented as anterior and localized.
