Cyclophoria

This code describes a type of latent strabismus where there is a tendency for the eye to rotate around its anteroposterior axis when fusion is disrupted. It is a phoria, meaning the deviation is only present when binocular vision is interrupted, unlike a tropia which is a constant misalignment. Patients may experience asthenopia, diplopia, or blurred vision, especially during prolonged visual tasks.

Use this code when documentation specifies cyclophoria, indicating an intermittent torsional deviation of the eye. This diagnosis is typically made during an ophthalmological or optometric examination, often through cover-uncover tests or Maddox rod testing. Ensure the medical record clearly identifies the condition as a phoria, not a constant deviation.

• Differentiate from cyclotropia (constant torsional misalignment), which is coded differently.
• Ensure the documentation specifies "cyclophoria" to support this code; general strabismus terms are insufficient.
• Consider laterality if specified, although cyclophoria is often bilateral or not specified by side.
