Scleral ectasia, bilateral

This code describes a condition where there is a localized thinning and bulging of the sclera, the white outer layer of the eye, affecting both eyes. This ectasia can lead to visual disturbances and other ocular complications due to the altered structural integrity of the globe.

Apply this code when documentation explicitly states "scleral ectasia" and specifies that both eyes are affected. This diagnosis is typically made by an ophthalmologist based on clinical examination and imaging studies.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish from staphyloma, which involves protrusion of the uvea through a thinned sclera.
• Code any associated underlying conditions or complications, such as myopia or glaucoma, separately.
