Scleral ectasia, right eye

This code signifies an abnormal thinning and bulging of the sclera, the white outer layer of the eye, specifically affecting the right eye. Scleral ectasia indicates a localized or generalized weakening of the scleral tissue, leading to its outward distension. This condition can compromise the structural integrity of the globe.

Use this code when documentation clearly indicates a diagnosis of scleral ectasia affecting the right eye. This diagnosis is typically made through ophthalmological examination, including slit-lamp biomicroscopy and potentially imaging studies confirming scleral thinning and protrusion.

• Ensure laterality is explicitly documented for the right eye; do not assume.
• Distinguish from staphyloma, which involves protrusion of uveal tissue through a thinned sclera.
• Code any underlying conditions contributing to the ectasia, such as high myopia or inflammatory diseases, as additional diagnoses.
