ICD-10: H53.53

Deuteranomaly, classified under the ICD-10 code H53.53, is a type of color vision deficiency characterized by a reduced sensitivity to green light. This condition is part of a broader category of color vision defects, which also includes protanopia and tritanopia. Diagnosing deuteranomaly involves several criteria and methods, which are outlined below.

Diagnostic Criteria for Deuteranomaly

1. Clinical Evaluation

• Patient History: A thorough patient history is essential, including any reported difficulties in color discrimination, particularly with greens and reds. Family history of color vision deficiencies may also be relevant, as deuteranomaly is often hereditary.
• Symptom Assessment: Patients may describe challenges in distinguishing between colors, particularly in low-light conditions or when colors are similar in hue.

2. Color Vision Testing

• Ishihara Test: This is one of the most common tests used to assess color vision. It involves identifying numbers or patterns within a series of colored plates. Individuals with deuteranomaly may struggle with specific plates that contain green and red hues.
• Farnsworth-Munsell 100 Hue Test: This test evaluates the ability to arrange colored caps in order of hue. Individuals with deuteranomaly typically show difficulty in arranging caps that are predominantly green.
• Anomaloscope: This specialized device allows for the assessment of color matching abilities. Patients with deuteranomaly will have a specific pattern of responses that indicates their color discrimination capabilities.

3. Visual Acuity and Other Tests

• Visual Acuity Assessment: While not directly related to color vision, assessing visual acuity can help rule out other visual impairments that may affect color perception.
• Dark Adaptation Tests: These tests measure how well the eyes adjust to darkness, which can also provide insights into overall visual function.

4. Genetic Testing

• In some cases, genetic testing may be conducted to confirm the diagnosis, especially if there is a family history of color vision deficiencies. This can help identify specific genetic mutations associated with deuteranomaly.

Conclusion

The diagnosis of deuteranomaly (ICD-10 code H53.53) relies on a combination of clinical evaluation, color vision testing, and potentially genetic analysis. Accurate diagnosis is crucial for understanding the extent of the color vision deficiency and for providing appropriate guidance and support to affected individuals. If you suspect you or someone else may have deuteranomaly, consulting with an eye care professional for comprehensive testing is recommended.

Deuteranomaly, classified under ICD-10 code H53.53, is a type of color vision deficiency characterized by a reduced sensitivity to green light. This condition is a form of red-green color blindness, which is the most common type of color vision deficiency. Below, we explore the clinical presentation, signs, symptoms, and patient characteristics associated with deuteranomaly.

Clinical Presentation

Definition and Mechanism

Deuteranomaly occurs due to a genetic mutation affecting the photopigments in the cone cells of the retina, specifically the M-cones (medium-wavelength cones) that are responsible for detecting green light. Individuals with deuteranomaly have a shifted sensitivity in their green photopigments, leading to difficulties in distinguishing between certain colors, particularly shades of green and red[1][2].

Patient Characteristics

• Prevalence: Deuteranomaly is more common in males, with an estimated prevalence of about 5% to 8% in the male population, while it is much rarer in females, occurring in approximately 0.5% of the female population due to its X-linked inheritance pattern[3][4].
• Genetic Background: The condition is inherited in an X-linked recessive manner, meaning that males are more frequently affected because they have only one X chromosome, while females have two, which can mask the effects of the mutation[5].

Signs and Symptoms

Visual Symptoms

• Color Discrimination Issues: Individuals with deuteranomaly often struggle to differentiate between colors that contain red and green components. For example, they may confuse shades of green with shades of brown or gray[6].
• Difficulty with Color Naming: Patients may have trouble accurately naming colors, particularly in low-light conditions or when colors are similar in hue[7].
• Reduced Color Intensity: Colors may appear less vibrant or washed out, particularly greens and reds, which can affect daily activities such as selecting clothing or interpreting traffic signals[8].

Behavioral Symptoms

• Avoidance of Color-Dependent Tasks: Individuals may avoid activities that require precise color discrimination, such as painting, certain professions (e.g., electrical work), or even hobbies like gardening[9].
• Frustration or Anxiety: Some patients may experience frustration or anxiety when faced with tasks that require color identification, leading to social withdrawal or reduced participation in activities[10].

Diagnosis and Assessment

Clinical Evaluation

• Color Vision Tests: Diagnosis typically involves color vision tests, such as the Ishihara test or the Farnsworth-Munsell 100 Hue test, which assess the ability to distinguish between different colors[11].
• Family History: A thorough family history is often taken, as color vision deficiencies can run in families, particularly on the maternal side due to the X-linked inheritance pattern[12].

Additional Considerations

• Impact on Daily Life: The degree of impact on daily life can vary significantly among individuals, with some adapting well and others experiencing significant challenges[13].

Conclusion

Deuteranomaly, represented by ICD-10 code H53.53, is a common form of color vision deficiency primarily affecting males. It is characterized by difficulties in distinguishing between certain colors, particularly greens and reds, due to genetic factors. Understanding the clinical presentation, signs, symptoms, and patient characteristics is crucial for proper diagnosis and management. Individuals with deuteranomaly may benefit from supportive strategies and accommodations in both personal and professional settings to enhance their quality of life.

For further information or specific inquiries regarding management strategies, consulting with an eye care professional or a genetic counselor may be beneficial.
