Eyelid surgery in ocular myopathies

To retrospectively analyse surgical outcome and complications in patients with ocular myopathy undergoing ptosis correction and to introduce preoperative prophylactic lower lid elevation in this group.

The medical records of all ocular myopathy patients who had undergone oculoplastic surgery between June 1995 and May 2006 were obtained. Patients' demographics, surgical details and measurements, and complications were recorded.

29 patients were identified; 21 with chronic progressive external ophthalmoplegia (CPEO), 7 with myotonic dystrophy (MD) and 1 with oculopharyngeal muscular dystrophy (OPMD). Then, 61 procedures to adjust eyelid height were performed, comprising levator resection, brow suspension, anterior lamellar repositioning, lower lid elevation and upper lid lowering. Palpebral aperture was significantly increased in all patient groups, by procedure and diagnosis, more significantly following brow suspension compared with levator resection. The patients' feedback was very positive. Post-operative complications were few, included corneal exposure and ulceration, ptosis recurrence, arched brow, and sling infection, all of which were successfully treated.

Our results demonstrate subjective and objective benefit following surgery in these patients, with a low complication rate. The use of pre-operative prophylactic lower lid elevation procedures is a promising modality.
