OBJECTIVE: To investigate the effect of previous incisional double-fold surgery on spontaneous resolution of eyelid retraction caused by Graves orbitopathy (GO) in Asian individuals.
DESIGN: Retrospective review of medical records.
PARTICIPANTS: Patients (N = 30; 39 eyes) with eyelid retraction associated with GO with symptom duration of less than 6 months.
METHODS: Patients who visited the Ophthalmology Department of Severance Hospital, Yonsei University, between January 2010 and December 2011, followed up for more than 6 months and in a euthyroid state with antithyroid drug treatment were included. Patients treated with steroids or who underwent surgery during follow-up were excluded. Upper scleral show was measured as the distance between the central upper lid margin and limbus at initial presentation and after 6 months. Comparative analysis was performed between the 2 groups delineated by history (n = 12; 16 eyes), or lack thereof (n = 18; 23 eyes), of incisional double-fold surgery before onset of GO symptoms and signs.
RESULTS: Patient demographics and initial upper scleral show were not significantly different between groups. In both groups, upper scleral show significantly decreased at 6 months of follow-up (p < 0.001 in both groups); however, improvement of upper scleral show was significantly reduced in patients who had undergone previous double-fold surgery (0.8 ± 0.5 mm) than in nonsurgical patients (1.8 ± 0.5 mm; p < 0.001).
CONCLUSIONS: Graves eyelid retraction resolves spontaneously over time, albeit not completely. Previous double-fold surgery hinders the degree of spontaneous resolution, probably because of the fibrosis and cicatrization between the skin, the subcutaneous layer, and the levator complex.
