ICD-10: H35.319

Nonexudative age-related macular degeneration (AMD), classified under ICD-10 code H35.319, is a common eye condition primarily affecting older adults. This condition is characterized by the gradual deterioration of the macula, the central part of the retina responsible for sharp, detailed vision. Below, we explore the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Overview

Nonexudative AMD, also known as dry AMD, is the most prevalent form of age-related macular degeneration. It typically progresses slowly and can lead to significant vision impairment over time. The condition is often asymptomatic in its early stages, making regular eye examinations crucial for early detection.

Stages of Nonexudative AMD

1. Early Stage: Patients may not notice any symptoms. However, during an eye exam, the presence of drusen (yellow deposits under the retina) may be observed.
2. Intermediate Stage: Patients may begin to experience mild vision changes, such as difficulty seeing in low light or noticing blurred spots in their central vision.
3. Late Stage: Significant vision loss can occur, affecting the ability to read, drive, or recognize faces.

Signs and Symptoms

Common Symptoms

• Blurred or Distorted Vision: Patients may report that straight lines appear wavy or distorted, a phenomenon known as metamorphopsia.
• Difficulty with Color Perception: Changes in color perception may occur, making it challenging to distinguish between similar colors.
• Central Vision Loss: As the disease progresses, patients may experience a gradual loss of central vision, leading to a blind spot in the center of their visual field.
• Difficulty Adapting to Changes in Light: Patients may find it hard to adjust to different lighting conditions, such as moving from bright to dim environments.

Signs Detected During Examination

• Drusen: The presence of drusen is a hallmark sign of nonexudative AMD. These can vary in size and number.
• Retinal Pigment Epithelium Changes: Alterations in the retinal pigment epithelium may be observed, including atrophy or hyperpigmentation.
