ABSTRACT
PURPOSE:
To evaluate the long-term outcomes of the palpebral fissure transfer (PFT) technique without lower eyelid spacer in patients with chronic progressive external ophthalmoplegia (CPEO).DESIGN:
Retrospective interventional case series.METHODS:
Consecutive patients with CPEO with PFT surgery (2006-2017) and a minimum follow-up of 24 months were included. The PFT included simultaneous levator resection or frontalis sling (based on the levator function and Bell's phenomenon) and lower eyelid retractor recession without spacer. Primary outcome measures included the change in margin reflex distance 1 (MRD-1), MRD-2, and palpebral fissure height (PFH) in the course of time. Potential predictors of keratopathy were also explored.RESULTS:
There were 32 patients (64 eyelids) with the mean age and follow-up of 34.1 years (range 15-56 years) and 37.9 months (range 24-72 months), respectively. Mean MRD-1 significantly increased from -0.9 mm to 3.4 mm in postoperative weeks 1 and 2 and 1.8 mm at the last follow-up. Mean MRD-2 significantly decreased from 5.6 mm to 3.7 mm in postoperative weeks 1 and 2 and 5 mm at the last follow-up. Eyes with frank lower eyelid retraction (MRD-2 >5 mm) gained more reduction in MRD-2 compared with those with no sclera show (-0.9 mm vs -0.3 mm, P < .001). Reoperation was performed in 9 eyelids for under- (n = 5) and overcorrection (n = 4). Persistent keratopathy was observed in 3 eyes (4.5%).CONCLUSION:
Lower eyelid retractor recession without spacer yields significant protective corneal coverage at the critical early postoperative period when the risk of keratopathy is highest.
