ICD-10: H53.54

Protanomaly, classified under ICD-10 code H53.54, is a type of color vision deficiency characterized by a reduced sensitivity to red light. This condition is part of a broader category of color vision deficiencies, which also includes protanopia and other forms of color blindness. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with protanomaly is essential for accurate diagnosis and management.

Clinical Presentation

Definition and Mechanism

Protanomaly is a genetic condition that affects the perception of colors, particularly those in the red spectrum. Individuals with protanomaly have a deficiency in the red photopigments in the cone cells of the retina, leading to difficulties in distinguishing between red and green hues. This condition is often inherited in an X-linked recessive pattern, predominantly affecting males.

Signs and Symptoms

Patients with protanomaly may exhibit the following signs and symptoms:

• Color Discrimination Issues: Difficulty in distinguishing between red and green colors, which may appear similar or indistinguishable.
• Reduced Brightness Perception: Red colors may appear less bright compared to other colors, leading to challenges in tasks that require color differentiation.
• Visual Fatigue: Prolonged tasks involving color discrimination may lead to visual fatigue or discomfort.
• Difficulty in Color Naming: Patients may struggle to accurately name colors, particularly those in the red-green spectrum.

Visual Acuity

While protanomaly primarily affects color perception, it does not typically impact overall visual acuity. Most individuals with this condition have normal vision in terms of clarity and sharpness, although they may experience challenges in specific lighting conditions or with certain color combinations.

Patient Characteristics

Demographics

• Gender: Protanomaly is more common in males due to its X-linked inheritance pattern. Approximately 1% of males are affected, while the prevalence in females is significantly lower, around 0.01%[1].
• Age: Symptoms of protanomaly are usually present from childhood, although they may not be recognized until later in life when color discrimination becomes more critical in daily activities.

Family History

A family history of color vision deficiencies can be a significant indicator of protanomaly. Individuals with affected relatives are at a higher risk of inheriting the condition.

Occupational Considerations

Patients with protanomaly may face challenges in certain professions that require precise color discrimination, such as graphic design, electrical work, or any field where color coding is essential. Awareness of this condition is crucial for educational and occupational guidance.

Conclusion

Protanomaly, represented by ICD-10 code H53.54, is a color vision deficiency that primarily affects the perception of red hues. Understanding its clinical presentation, including the signs and symptoms, as well as the characteristics of affected patients, is vital for healthcare providers. Early diagnosis and appropriate management strategies can help individuals adapt to their color vision challenges, ensuring they can navigate daily life and professional environments effectively.

Protanomaly, classified under the ICD-10 code H53.54, is a type of color vision deficiency characterized by a reduced sensitivity to red light. This condition is part of a broader category of color vision defects, which also includes protanopia and deuteranopia. Diagnosing protanomaly involves several criteria and assessments, which are outlined below.

Diagnostic Criteria for Protanomaly

1. Clinical History

• Patient Symptoms: The initial step in diagnosing protanomaly involves gathering a detailed clinical history from the patient. Symptoms may include difficulty distinguishing between red and green hues, particularly in low-light conditions or when colors are similar in brightness.
• Family History: Since color vision deficiencies often have a genetic component, a family history of color vision problems can be significant in the diagnostic process.

2. Visual Acuity Testing

• Standard Visual Acuity Tests: Before assessing color vision, standard visual acuity tests are performed to ensure that the patient’s overall vision is adequate. This helps rule out other visual impairments that could affect color perception.

3. Color Vision Testing

• Ishihara Test: This is one of the most common tests used to diagnose color vision deficiencies. It involves identifying numbers or patterns within a series of colored plates. Individuals with protanomaly may struggle to see certain numbers that rely on red hues.
