ICD-10: E70.318

Ocular albinism is a genetic condition characterized by a reduction or absence of melanin in the eyes, leading to various visual impairments. The ICD-10-CM code E70.318 specifically refers to "Other ocular albinism," which encompasses forms of ocular albinism that do not fall under the more commonly recognized types, such as ocular albinism type 1 (OA1).

Clinical Description of Ocular Albinism

Definition and Types

Ocular albinism primarily affects the eyes, resulting in features such as reduced pigmentation in the iris and retina. This condition can lead to significant visual problems, including:

• Nystagmus: Involuntary eye movements that can affect vision stability.
• Strabismus: Misalignment of the eyes, which can lead to double vision or amblyopia (lazy eye).
• Photophobia: Increased sensitivity to light due to the lack of pigment that normally protects the eyes from bright light.

While E70.318 covers "Other ocular albinism," it is important to note that the most common form, OA1, is linked to mutations in the GPR143 gene and is typically inherited in an X-linked manner, predominantly affecting males. Other forms may arise from different genetic mutations or syndromic associations, which are classified under this code.

Symptoms and Diagnosis

Symptoms of ocular albinism can vary widely among individuals but generally include:

• Visual acuity issues: Many individuals experience reduced vision, which may not be correctable with glasses.
• Color vision deficiencies: Some may have difficulty distinguishing between certain colors.
• Abnormal retinal development: This can lead to structural changes in the retina, affecting overall vision.

Diagnosis is typically made through a combination of clinical examination, family history, and genetic testing to identify specific mutations associated with the condition.

Diagnostic Criteria for Ocular Albinism

The diagnosis of ocular albinism, including the subtype represented by E70.318, typically involves several key criteria:

1. Clinical Evaluation

• Family History: A detailed family history is essential, as ocular albinism is often inherited in an X-linked recessive pattern (in the case of OA1) or autosomal recessive patterns for other types. A history of similar conditions in family members can support the diagnosis.
• Physical Examination: An ophthalmologist will conduct a thorough eye examination, looking for characteristic features such as:
  • Reduced pigmentation in the iris and retina.
  • Nystagmus (involuntary eye movement).
  • Strabismus (misalignment of the eyes).
  • Photophobia (sensitivity to light).

2. Visual Function Assessment

• Visual Acuity Testing: Patients often exhibit reduced visual acuity, which can be assessed using standard vision tests.
• Visual Field Testing: This may reveal abnormalities in peripheral vision, which is common in individuals with ocular albinism.

3. Genetic Testing

• Molecular Genetic Testing: Genetic testing can confirm the diagnosis by identifying mutations in genes associated with ocular albinism, such as the GPR143 gene for OA1 or other genes linked to different forms of ocular albinism. This is particularly useful for distinguishing between types and confirming the diagnosis when clinical features are ambiguous.

4. Imaging Studies

• Fundus Photography: This imaging technique can document the appearance of the retina and assess for any abnormalities associated with albinism, such as foveal hypoplasia (underdevelopment of the fovea).
• Optical Coherence Tomography (OCT): OCT can provide detailed images of the retina, helping to identify structural changes that may be present in ocular albinism.

Conclusion

The diagnosis of E70.318: Other ocular albinism involves a combination of clinical evaluation, visual function assessment, genetic testing, and imaging studies. Each of these components plays a crucial role in confirming the presence of ocular albinism and distinguishing it from other visual disorders.
