Abstract

Purpose: To report the influence of unilateral upper eyelid retraction repair on the upper eyelid position of the contralateral, non-operative side. Methods: An IRB-approved retrospective chart review was performed to identify patients who underwent unilateral upper eyelid retraction repair. Patient demographics, etiology of upper eyelid retraction, previous surgeries, and periocular measurements from pre-operative and follow-up visits were reviewed. Results: Thirteen patients who underwent unilateral upper eyelid retraction repair due to thyroid eye disease or iatrogenic retraction secondary to ptosis repair demonstrated an elevation in contralateral eyelid height post-operatively. The mean pre-operative MRD-1 was 6.6 mm in the operative eye and 2.6 mm in the contralateral eye. All patients demonstrated a decreased MRD-1 in the operative eye (mean change: −2.6 mm [−38.4%]; standard deviation [SD]: 1.2 mm) and an increased MRD-1 in the contralateral eye (mean change: +1.3 mm [+62.4%]; SD: 0.6 mm) following unilateral upper eyelid retraction repair. The mean post-operative MRD-1 measurements were 4.0 mm ± 0.5 mm and 3.9 mm ± 0.6 mm in the operative and contralateral eyes, respectively. Conclusions: Unilateral upper eyelid retraction repair may induce an elevation of the contralateral upper eyelid position in some patients. The findings in this report may support unilateral intervention in patients with upper lid retraction, especially in the setting of contralateral blepharoptosis.
