Area of Science:

  • Ophthalmology
  • Strabismus Surgery
  • Pediatric Ophthalmology

Background:

  • Brown's syndrome is a condition characterized by limited elevation of the eye.
  • It can cause compensatory head tilting and affect binocular vision.
  • Surgical intervention is sometimes necessary for persistent or severe cases.

Purpose of the Study:

  • To evaluate the efficacy of longitudinal tenectomy of the superior oblique muscle's reflected tendon in treating Brown's syndrome.
  • To identify surgical criteria and assess the surgical method for Brown's syndrome.

Main Methods:

  • Retrospective review of 9 eyes with Brown's syndrome undergoing surgery.
  • Surgical technique involved tenectomy of a thickened superior oblique tendon.
  • Application of methylprednisolone acetate to prevent adhesions.

Main Results:

  • All 9 patients achieved normal head posture and satisfactory upward vergence post-surgery.
  • These positive outcomes were maintained throughout the follow-up period.
  • Pre- and postoperative assessments confirmed the functional improvements.

Conclusions:

  • Exploration and surgical trimming of a thickened superior oblique tendon are recommended for Brown's syndrome.
  • Delayed trochlear development may be a contributing factor to Brown's syndrome.
  • Tenectomy of the reflected tendon is an effective treatment for Brown's syndrome.
