H35.03 Hypertensive retinopathy

Name of the Condition

• Hypertensive Retinopathy

Summary

Hypertensive retinopathy is a condition caused by high blood pressure that affects the blood vessels in the retina. It can lead to changes in vision and, if untreated, may result in severe eye complications.

Causes

The primary cause is chronic high blood pressure (hypertension), which damages the retinal blood vessels over time.

Risk Factors

• Persistent high blood pressure
• Diabetes
• High cholesterol
• Smoking
• Age (increased risk with older age)

Symptoms

• Blurred vision
• Double vision
• Eye pain or discomfort
• Reduced vision

Diagnosis

A comprehensive eye examination, including fundoscopic evaluation, is used to assess retinal changes. Blood pressure measurement and additional tests like fluorescein angiography may be performed if needed.

Treatment Options

• Managing high blood pressure with antihypertensive medications
• Lifestyle modifications (e.g., diet, exercise)
• Regular monitoring of blood pressure and eye health

Prognosis and Follow-Up

With effective blood pressure control, retinal damage can be stabilized. Regular follow-ups with an ophthalmologist and primary care physician are recommended to prevent progression.

Complications

• Vision loss
• Retinal hemorrhage
• Retinal detachment

Lifestyle & Prevention

• Maintain a healthy blood pressure through diet and exercise
• Avoid smoking
• Manage other vascular risk factors (e.g., cholesterol, diabetes)

When to Seek Professional Help

Seek care if you experience sudden vision changes, eye pain, or persistent blurriness, as these may indicate worsening retinopathy.

Tips for Medical Coders

Document the presence of hypertensive retinopathy and any associated eye findings. Ensure clinical documentation supports the diagnosis and specifies laterality if applicable.
