Congenital fibrosis of inferior rectus muscle

Last edited: 4/15/2026

Overview

Congenital fibrosis of the inferior rectus muscle is a rare congenital anomaly characterized by restricted ocular motility due to fibrous bands affecting the inferior rectus muscle, often leading to vertical gaze palsy and head tilting 1.

Diagnosis

  • Clinical presentation includes vertical gaze palsy, head tilt, and potential horizontal gaze abnormalities 1.
  • Diagnostic imaging such as MRI or CT may be used to visualize the fibrous bands and assess muscle anatomy 1.
  • Electromyography (EMG) can help rule out other neuromuscular disorders 1.

    • Management

  • Surgical intervention, typically involving recession or resection of the inferior rectus muscle, is often required to improve ocular motility 1.
  • Postoperative rehabilitation with prism adaptation or vision therapy may enhance outcomes 1.
  • No specific pharmacological treatments are mentioned for congenital fibrosis of the inferior rectus muscle 1.

    • Special Populations

  • No specific guidelines or evidence addressing congenital fibrosis in pregnancy, pediatrics, elderly, or with comorbidities were provided in the given abstracts 1.

    • Key Recommendations

  • Consider MRI or CT imaging for definitive diagnosis and anatomical assessment of fibrous bands 1 (Evidence: Moderate).
  • Surgical correction, such as muscle recession or resection, is recommended for functional improvement 1 (Evidence: Expert opinion).
  • Postoperative vision therapy should be considered to optimize outcomes 1 (Evidence: Expert opinion).
