Ahn, Lee, Jang, Lee, Sin, and Baek: Clinical Efficacy of Blepharotomy for Upper Eyelid Retraction Associated with Thyroid Eye Disease

Abstract

Purpose

To investigate the clinical efficacy of blepharotomy to treat upper eyelid retraction associated with thyroid eye disease.

Methods

A retrospective survey was performed with 9 eyes of 7 thyroid ophthalmopathy patients, who visited Korea University Medical Center from August 2009 to February 2011, and had undergone blepharotomy. The sex, age, change of upper eyelid retraction, postoperative complication, follow-up periods, and the surgical results were reviewed. To assess the efficacy of blepharotomy more objectively, the preoperative and postoperative pictures of patients were taken and the following lid parameters measured: marginal reflex distance 1, interpalpebral fissure height, total palpebral fissure area, upper nasal palpebral fissure area, and upper temporal palpebral fissure area.

Results

The mean age of patients was 37.4 years and mean follow-up period was 12.8 months. Five patients had undergone surgery unilaterally and 2 patients, bilaterally. Seven eyes of 6 patients had undergone full thickness blepharotomy and 2 eyes of 1 patient had undergone graded blepharotomy. According to the 3-month preoperative and postoperative picture analysis, all lid parameters improved significantly after blepharotomy (2.03 mm, 1.95 mm, 24.28 mm2, 12.98 mm2, and 16.21 mm2, respectively). Complications associated with blepharotomy included multiple and high folds in 2 eyes of 2 patients who had undergone full thickness blepharotomy. Re-operation was performed on only 1 eye and the result was satisfactory.

Conclusions

Blepharotomy for upper eyelid retraction is a safe and highly effective surgery for upper eyelid retraction associated with symptomatic thyroid eye disease. This technique achieves excellent functional and cosmetic outcomes.

Figures and Tables

Figure 1
Pre and postoperative five lid parameters were measured by image J program. Marginal reflex distance 1 (MRD1, distance from the upper lid margin to the center of the pupil), interpalpebral fissure height (IPF, widest distance between the upper and lower lid margins), and total palpebral fissure area (TA) were measured. For defining the upper nasal area (UNA) and upper temporal area (UTA), a straight line connecting the medial and lateral canthi was drawn, and a perpendicular line passing through the center of the intercanthal line was drawn.
