H35.17 Retrolental fibroplasia

Name of the Condition

• Retrolental fibroplasia

Summary

Retrolental fibroplasia is a condition characterized by abnormal fibrous tissue growth behind the lens of the eye, often associated with retinopathy of prematurity. This can lead to visual impairment or blindness if untreated. The condition primarily affects premature infants, with severity varying based on gestational age and other factors.

Causes

Retrolental fibroplasia is caused by abnormal retinal vascular development in premature infants. The retina, which normally completes vascularization by full-term birth, may not fully develop in preterm infants. Factors such as oxygen therapy, fluctuations in oxygen levels, and the infant's overall immaturity contribute to abnormal tissue growth behind the lens.

Risk Factors

• Prematurity (especially infants born before 31 weeks of gestation).
• Low birth weight (typically under 1500 grams).
• Oxygen therapy or fluctuations in oxygen levels during neonatal care.
• Multiple births (e.g., twins or triplets).
• Certain medical conditions affecting oxygen delivery or retinal development.

Symptoms

In early stages, retrolental fibroplasia may not present obvious symptoms. Severe cases can lead to abnormal eye movements, a white appearance of the pupil (leukocoria), or vision impairment as the child grows. Infants with this condition are typically asymptomatic, and diagnosis relies on screening.

Diagnosis

Diagnosis involves a comprehensive eye examination, often using indirect ophthalmoscopy to assess retinal and fibrous tissue changes. Imaging or specialized tests may be used to evaluate the extent of abnormal growth behind the lens. Regular screening is recommended for premature infants at risk.

Treatment Options

Treatment depends on severity and may include monitoring for mild cases. Severe cases may require laser therapy, cryotherapy, or surgical intervention to address retinal detachment or fibrous tissue. Early intervention is critical to prevent vision loss.

Prognosis and Follow-Up

Prognosis varies based on the stage and response to treatment. Mild cases may resolve with monitoring, while severe cases can lead to permanent vision impairment. Long-term follow-up is essential to assess visual development and address complications.

Complications

Potential complications include retinal detachment, glaucoma, strabismus, or permanent vision loss. Advanced cases may require ongoing management to preserve visual function.

Lifestyle & Prevention

Prevention focuses on careful oxygen management in premature infants and regular screening for early detection. Supportive care, including vision rehabilitation, may be needed for affected individuals.

When to Seek Professional Help

Seek immediate medical attention if signs of visual impairment, abnormal eye movements, or leukocoria are observed in an infant. Early evaluation is crucial for timely intervention.

Tips for Medical Coders

Document the clinical findings, including the presence of fibrous tissue behind the lens and any associated retinal changes. Ensure documentation supports the diagnosis and severity to accurately reflect the condition for coding purposes.
