H54.2 Low vision, both eyes

Name of the Condition

• Low vision, both eyes (ICD Code: H54.2)

Summary

Low vision, both eyes refers to significant visual impairment in both eyes that cannot be fully corrected with standard glasses, contact lenses, or surgery, but retains some usable vision. This condition impacts daily functioning and may require adaptive strategies or assistive devices to perform tasks that rely on sight.

Causes

Visual impairment in both eyes can result from various ocular or systemic conditions. Common causes include age-related macular degeneration, diabetic retinopathy, glaucoma, cataracts, retinal detachment, optic nerve disorders, or congenital abnormalities. Infections, injuries, or degenerative diseases may also contribute to bilateral low vision.

Risk Factors

Age is a significant risk factor, as many eye conditions develop or worsen over time. Other factors include genetic predisposition, chronic diseases like diabetes or hypertension, smoking, prolonged UV exposure, and a history of eye trauma or surgery. Certain medications or nutritional deficiencies may also play a role.

Symptoms

Symptoms vary based on the type and severity of visual loss. They may include blurred or distorted vision, difficulty seeing in low light, loss of peripheral vision, blind spots, or reduced visual acuity even with correction. Daily activities such as reading, driving, or recognizing faces may be challenging.

Diagnosis

Comprehensive eye examinations by an ophthalmologist, which may include visual acuity tests, imaging of the eye structures (like an OCT scan), and assessment of visual fields. Functional vision assessments may also be performed to determine the impact on daily tasks.

Treatment Options

Treatment focuses on maximizing remaining vision and enhancing quality of life. Options may include low vision aids (e.g., magnifiers, telescopic glasses), adaptive techniques, or referral to vision rehabilitation services. Underlying conditions contributing to vision loss may be managed to slow progression.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and severity of vision loss. Regular follow-up with an eye care provider is essential to monitor changes, adjust treatments, and address complications. Early intervention can help preserve remaining vision and improve functional outcomes.

Complications

Complications may include difficulty with mobility, increased risk of falls, challenges with daily tasks, and potential psychological impacts such as depression or anxiety. Reduced visual function can also affect independence and overall quality of life.

Lifestyle & Prevention

Lifestyle modifications may include using adequate lighting, reducing glare, and organizing spaces for easier navigation. Preventive measures include regular eye exams, managing chronic conditions (e.g., diabetes), protecting eyes from injury, and avoiding smoking. Nutritional support (e.g., antioxidants) may also be considered.

When to Seek Professional Help

Seek prompt medical attention for sudden changes in vision, persistent blurriness, loss of peripheral vision, or difficulty with daily activities. Early evaluation is critical to address reversible causes or slow progression of vision loss.

Tips for Medical Coders

Document the bilateral nature of low vision and any contributing factors (e.g., underlying eye conditions) to support accurate coding. Ensure clinical documentation specifies the extent of visual impairment and any functional limitations. Review guidelines for coding bilateral low vision to ensure compliance with ICD-10-CM conventions.
