ICD-10: H53.469

The ICD-10 code H53.469 refers to "Homonymous bilateral field defects, unspecified side." This classification falls under the broader category of visual disturbances, specifically addressing issues related to the visual field that affect both eyes in a homonymous manner.

Clinical Description

Definition

Homonymous bilateral field defects are characterized by a loss of vision in the same visual field area in both eyes. This condition can manifest as a complete or partial loss of vision, typically affecting either the right or left side of the visual field. The term "homonymous" indicates that the defect is symmetrical across both eyes, which is a critical aspect of diagnosing and understanding the condition.

Causes

The underlying causes of homonymous bilateral field defects can vary widely and may include:

• Neurological Conditions: Damage to the optic pathways, such as from strokes, tumors, or traumatic brain injuries, can lead to these visual field defects. For instance, lesions in the occipital lobe or along the optic tract are common culprits.
• Vascular Issues: Conditions like ischemic optic neuropathy or other vascular insults can also result in homonymous field defects.
• Degenerative Diseases: Certain degenerative diseases affecting the nervous system may contribute to the development of these visual disturbances.

Symptoms

Patients with homonymous bilateral field defects may experience:

• Difficulty seeing objects on one side of their visual field, which can affect daily activities such as driving or reading.
