E70.311 Autosomal recessive ocular albinism

Name of the Condition

• Autosomal recessive ocular albinism (ICD-10-CM Code: E70.311)

Summary

Autosomal recessive ocular albinism is a genetic condition characterized by reduced or absent melanin production primarily affecting the eyes, while skin and hair pigmentation may remain relatively normal. This condition impacts vision due to abnormal development of the optic nerves and retinas, leading to characteristic visual impairments.

Causes

Autosomal recessive ocular albinism results from mutations in genes responsible for melanin synthesis or transport, specifically affecting ocular pigmentation. These genetic changes disrupt melanin production in the eyes, a pigment critical for normal retinal and optic nerve development.

Risk Factors

• Genetic inheritance; typically autosomal recessive, requiring mutations in both copies of a gene.
• Family history of ocular albinism.
• Carrier status in parents or relatives.

Symptoms

• Light-colored or translucent irises.
• Vision issues, including nystagmus, strabismus, photophobia, and reduced visual acuity.
• Abnormal optic nerve development (foveal hypoplasia).
• Normal or near-normal skin and hair pigmentation.

Diagnosis

Diagnosis involves a physical exam to assess ocular pigmentation, detailed ocular evaluations by an ophthalmologist, and genetic testing to identify specific mutations. Clinical evaluation is often necessary, as newborn screening may not detect this condition.

Treatment Options

Management focuses on symptom relief: corrective lenses for vision problems, protective eyewear for photophobia, and regular monitoring of ocular health. Genetic counseling may be recommended for affected individuals and their families.

Prognosis and Follow-Up

Prognosis varies based on the severity of visual impairment. Regular follow-up with an ophthalmologist is essential to monitor vision and address complications. Early intervention can help manage symptoms and improve quality of life.

Complications

• Severe visual impairment or blindness.
• Increased risk of sun-related eye damage due to photophobia.
• Potential social or educational challenges related to vision loss.

Lifestyle & Prevention

• Use protective eyewear outdoors to reduce photophobia and eye strain.
• Avoid excessive sun exposure to prevent eye damage.
• Seek early vision support services for educational or developmental needs.

When to Seek Professional Help

Consult a healthcare provider if you or a family member experiences persistent vision problems, unusual eye appearance, or if there is a known family history of ocular albinism.

Tips for Medical Coders

Document the specific genetic inheritance pattern (autosomal recessive) and confirm ocular involvement without systemic pigmentation changes. Ensure clinical documentation supports the diagnosis and differentiates it from other forms of albinism.
