[Clinical characteristics of moderate and severe Marcus-Gunn jaw-winking synkinesis and its surgical treatment].

OBJECTIVE

To investigate the clinical characteristics of moderate and severe Marcus-Gunn jaw winking synkinesis and it surgical management.

METHODS

Thirty-three patients with Marcus-Gunn syndrome were enrolled from 1997 to 2003 in Zhongshan Ophthalmic Center. The clinical characteristics were analyzed based on the records. Unilateral levator excision and frontalis flap suspension were performed for the correction of ptosis and the results were analyzed.

RESULTS

The follow-up period varied from 1 to 6 years. Sixteen patients were male and 17 were female. The left eye was involved in 22 patients and the right eye in 11 patients. There was no family history. The amount of ptosis in each patient was more than 2 mm. At the end of observation, good results were achieved for ptosis correction in 26 (87%) of 30 patients, fair results in 3 (10%) patients.

CONCLUSIONS

The ptosis of patients with moderate and severe Marcus-Gunn syndrome needs to be treated surgically. Unilateral frontalis flap suspension combined levator excision can correct ptosis very well for patients with moderate and severe Marcus-Gunn syndrome.
