ICD-10: S04.11

The ICD-10 code S04.11 refers to an injury of the oculomotor nerve on the right side. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and management.

Clinical Presentation

Injuries to the oculomotor nerve can result from various causes, including trauma, compression, or ischemia. The clinical presentation typically includes a combination of motor and sensory deficits due to the nerve's role in eye movement and pupil response.

Signs and Symptoms

1. Ptosis: One of the hallmark signs of oculomotor nerve injury is ptosis, or drooping of the upper eyelid, which occurs due to paralysis of the levator palpebrae superioris muscle[1].

2. Diplopia: Patients may experience double vision (diplopia) because the oculomotor nerve controls most of the extraocular muscles responsible for eye movement. This can lead to misalignment of the eyes[1][2].

3. Pupil Abnormalities: The oculomotor nerve also innervates the sphincter pupillae muscle, which constricts the pupil. Injury can result in a dilated pupil (mydriasis) that does not respond to light, indicating a loss of parasympathetic function[2].

4. Eye Position: The affected eye may be positioned down and out due to unopposed action of the lateral rectus and superior oblique muscles, which are innervated by other cranial nerves[1][3].

5. Loss of Accommodation: Patients may have difficulty focusing on near objects due to paralysis of the ciliary muscle, which is also innervated by the oculomotor nerve[2].

Patient Characteristics

• Demographics: Oculomotor nerve injuries can occur in individuals of any age but are more common in adults due to trauma or vascular issues. The right side may be affected due to specific injuries or conditions that impact that side of the body[3].

• Medical History: Patients may have a history of head trauma, aneurysms, or conditions such as diabetes mellitus, which can predispose them to nerve injuries due to ischemia or neuropathy[1][2].

• Neurological Assessment: A thorough neurological examination is essential to assess the extent of the injury and to rule out other potential causes of the symptoms, such as tumors or vascular malformations[3].

Conclusion

In summary, the clinical presentation of an oculomotor nerve injury on the right side (ICD-10 code S04.11) is characterized by ptosis, diplopia, pupil abnormalities, altered eye position, and loss of accommodation. Understanding these signs and symptoms, along with patient characteristics, is vital for healthcare providers to ensure accurate diagnosis and appropriate management of the condition. Early intervention can help mitigate complications and improve patient outcomes.
