Purpose:
Müller muscle-conjunctiva resection could be seen as a relative contraindication in patients with a prior history of a glaucoma filtering procedure, corneal disease, or corneal surgery. The concern centers around the theoretical risk of bleb-related complications or corneal damage from the palpebral conjunctival sutures. Our study aimed to determine whether any bleb- or cornea-related complications arose in patients who underwent Müller muscle-conjunctiva resection for ptosis correction.
Methods:
A retrospective chart review was performed on 2 practices of oculofacial plastic surgeons from 2000 to 2006, including patients who had ptosis correction by Müller muscle-conjunctiva resection. Patients with a prior history of a glaucoma filtering procedure, corneal disease, or corneal surgery were identified. Each case was reviewed to determine whether any bleb- or cornea-related complications occurred. The postoperative improvement of ptosis measured by interpalpebral distance or margin reflex distance-1 also was noted.
Results:
Forty-three patients and 55 eyes with a history of a glaucoma filtering procedure (13 patients/15 eyes), corneal disease (1 patient/1 eye), or corneal surgery (29 patients/39 eyes) who underwent Müller muscle-conjunctiva resection were identified. The average follow-up time was 212.4 days. No bleb-related complications occurred. One patient with a history of Reis-Bücklers dystrophy experienced a corneal abrasion. Fifty-two of 55 patients had objective improvement of their ptosis.
Conclusions:
Müller muscle-conjunctiva resection can provide an effective means for ptosis repair in patients with a prior history of a glaucoma filtering procedure, corneal disease, or corneal surgery. One temporary postoperative corneal complication occurred in our series.
