To investigate the surgical techniques of divided nevus of the eyelids with different locations and sizes.Retrospective observational case series. Thirty cases (30 eyes) of divided nevus of the eyelids in Zhongshan Ophthalmic Center from July 1997 to November 2006 were retrospectively reviewed. There were three different surgical methods. Excision of the nevus and direct suture after excision in 3 cases. Excision of the nevus and free skin graft transplantation in 5 cases. Excision of the nevus and transfer of skin flap, which included a two stages reconstruction, was performed in 22 cases. The upper or lower eyelid was treated first and another eyelid was treated after three months. Lacrimal punctum and lacrimal canaliculus were excised if they were involved in 8 cases among 22 cases.The mean follow-up time was 60 months (ranging from 2 years to 11 years). Only one case recurred after two years during follow-up and was excised after five years. Pathologic examination indicated malignant transformation. Excision with histopathological control was performed and the nevus did not recur during follow-up time. Recurrence or malignant transformation did not occur in other cases. Aesthetical results of skin flap transplantation were better than skin graft transplantation.The results of two stages reconstruction and transfer of skin flap after excision of the divided nevus are better than free skin graft transplantation. Close observation is required after excision of the divided nevus for early detection of malignant transformation.

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