AIM: To evaluate the clinical effect of lengthening of allogenic levetor muscle with scleral graft in correcting lower eyelid retraction in patients with inactive thyroid ophthalmopathy.

METHODS: Totally 12 patients(16 eyelids)with inactive thyroid associated ophthalmopathy were collected. All patients had a typical manifestation of lower eyelid retraction.

RESULTS: All patients had subjective improvement in appearance and symptom. We have found eyelid edema to be a common complication of sclera grafts.

CONCLUSION: Lengthening of allogenic levetor muscle with scleral graft is effective in correcting lower eyelid retraction.
