H35.171 Retrolental fibroplasia, right eye

Name of the Condition

• Retrolental fibroplasia, right eye

Summary

Retrolental fibroplasia, right eye is a condition involving abnormal fibrous tissue growth behind the lens of the right 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 routine screening.

Diagnosis

Diagnosis involves a comprehensive eye examination, including indirect ophthalmoscopy, to assess retinal vascular development and fibrous tissue growth. Imaging studies may be used to evaluate the extent of the condition. Screening is recommended for premature infants at risk, with follow-up based on initial findings.

Treatment Options

Treatment depends on the severity of the condition. Mild cases may require monitoring, while severe cases may involve laser therapy, cryotherapy, or surgical intervention to prevent retinal detachment. Early intervention is critical to preserve vision.

Prognosis and Follow-Up

Prognosis varies based on the stage and severity of the condition at diagnosis. Early detection and treatment improve outcomes, but some infants may experience permanent vision loss. Long-term follow-up is necessary to monitor for complications and adjust care as needed.

Complications

Potential complications include retinal detachment, strabismus, amblyopia, and permanent vision loss. Severe cases may lead to blindness if untreated. Regular monitoring helps identify and address complications promptly.

Lifestyle & Prevention

Prevention focuses on managing oxygen therapy in premature infants to avoid fluctuations that contribute to abnormal retinal development. Follow-up care and adherence to screening guidelines are essential for early detection and intervention.

When to Seek Professional Help

Seek immediate medical attention if symptoms such as leukocoria, abnormal eye movements, or vision impairment are observed. Routine screening for premature infants is critical to detect the condition early.

Tips for Medical Coders

Document the laterality (right eye) clearly in the medical record. Ensure the diagnosis is supported by clinical findings and screening results. Code H35.171 is specific to the right eye; verify documentation aligns with the code's specificity.
