Squint surgery in patients with Graves' ophthalmopathy

Area of Science:

• Ophthalmology
• Endocrinology
• Surgical Research

Background:

• Graves' ophthalmopathy frequently causes strabismus (squint) due to extraocular muscle dysfunction.
• Severe cases (NOSPECS class 4) often require surgical intervention to correct eye alignment and restore binocular vision.
• Previous treatments like prednisone or radiation may precede surgery in complex cases.

Purpose of the Study:

• To evaluate the efficacy of extraocular muscle surgery in patients with Graves' ophthalmopathy.
• To assess the surgical outcomes in terms of achieving orthophoria and binocular single vision.
• To analyze the surgical procedures performed on patients with advanced Graves' ophthalmopathy.

Main Methods:

• Retrospective analysis of 22 patients with Graves' ophthalmopathy (NOSPECS class 4) who underwent extraocular muscle surgery.
• Patients were euthyroid at the time of surgery with stable motility for at least 6 months.
• Surgical procedures included recession of the inferior rectus (11 times) and medial rectus (9 times), among others.

Main Results:

• All 22 patients achieved orthophoria postoperatively.
• A useful field of binocular single vision was successfully restored in all patients.
• The mean age of patients undergoing surgery was 55 years, with a female predominance (16 females, 6 males).

Conclusions:

• Extraocular muscle surgery is a highly effective treatment for strabismus in patients with Graves' ophthalmopathy.
• Surgical correction leads to successful restoration of binocular vision and ocular alignment.
• The study supports surgical intervention as a key component in managing severe Graves' ophthalmopathy.
