E11.3543 Type 2 diabetes mellitus with proliferative diabetic retinopathy with combined traction retinal detachment and rhegmatogenous retinal detachment, bilateral

Name of the Condition

• Common Name: Type 2 Diabetes with Proliferative Diabetic Retinopathy and Combined Retinal Detachment (Bilateral)
• Medical Term: Type 2 diabetes mellitus with proliferative diabetic retinopathy with combined traction retinal detachment and rhegmatogenous retinal detachment, bilateral

Summary

This condition is a severe complication of type 2 diabetes characterized by the growth of abnormal new blood vessels in the retina (proliferative diabetic retinopathy) and a combination of traction retinal detachment and rhegmatogenous retinal detachment affecting both eyes. It arises from prolonged high blood sugar levels damaging retinal blood vessels, potentially leading to vision impairment or blindness if untreated. The combination of proliferative changes and dual retinal detachment indicates advanced retinal damage requiring prompt management.

Causes

High blood sugar levels over time damage the small blood vessels in the retina, triggering the growth of fragile, abnormal blood vessels. These vessels can form scar tissue that pulls on the retina (traction detachment) and may also cause a tear or hole, leading to rhegmatogenous detachment. This process is driven by diabetes-related vascular changes and metabolic imbalances, which disrupt normal retinal function and structure.

Risk Factors

• Poorly controlled blood glucose levels.
• Long duration of diabetes.
• Hypertension.
• High cholesterol.
• Smoking.
• Family history of diabetic retinopathy.

Symptoms

• Sudden or gradual vision loss.
• Floaters or spots in the vision.
• Blurred or distorted vision.
• Dark or empty areas in the visual field.
• Difficulty seeing at night.

Diagnosis

Diagnosis involves a comprehensive eye examination, including dilated retinal imaging (e.g., fundus photography, optical coherence tomography) and fluorescein angiography to assess retinal blood vessel changes and detachment. Visual acuity tests and intraocular pressure measurements may also be performed to evaluate overall eye health.

Treatment Options

Treatment focuses on stabilizing retinal detachment and managing diabetic retinopathy. Options include laser photocoagulation, vitrectomy surgery to remove scar tissue or blood, and intraocular injections of anti-VEGF agents to reduce abnormal blood vessel growth. Blood sugar and blood pressure control are critical to prevent further progression.

Prognosis and Follow-Up

Prognosis depends on the severity of retinal damage and timeliness of treatment. Early intervention can preserve vision, but advanced cases may result in permanent vision loss. Regular follow-up with an ophthalmologist is essential to monitor for recurrence or progression, typically every 3–6 months.

Complications

• Permanent vision loss or blindness.
• Recurrent retinal detachment.
• Glaucoma due to abnormal blood vessel growth.
• Cataracts.

Lifestyle & Prevention

• Maintain strict blood glucose control through diet, exercise, and medication.
• Regular eye exams to detect early retinopathy.
• Manage blood pressure and cholesterol levels.
• Avoid smoking.
• Protect eyes from injury and UV exposure.

When to Seek Professional Help

Seek immediate medical attention for sudden vision changes, increased floaters, or flashes of light, as these may indicate retinal detachment. Regular eye evaluations are recommended for all individuals with type 2 diabetes, especially those with existing retinopathy.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record, as this specifies the involvement of both eyes. Ensure clinical documentation supports the presence of proliferative diabetic retinopathy with combined traction and rhegmatogenous retinal detachment to justify the code assignment.
