摘要

本文報告兩例因眼球內陷引起該側下眼瞼往上升，遮蓋住角膜下輪部，使得兩瞼裂大小不一致。同時在眼球向下轉動時下眼瞼亦無被拉動而向下凹的現象。此種現象在目前眼科文獻中尚無正式的報告。作者將其定義為「下眼瞼逆下垂」，以與一般所稱之下眼瞼下垂相區別。本文中並介紹一種新的手術方法一縮瞼韌帶切除法，來矯正此類患者。

Ptosis inversus means an elevating of the lower lid above its normal position. The lid can't be depressed at down gaze. It is a new term which is defined by authors. Two cases with unilateral enophthalmos had this problem. They were corrected successfully by lower lid retractor resection procedures which are to resect the lower lid retractor and to lower the lid level. It can move the lower lid down 2 to 2.5mm according to the level of the elevation. The operation procedures have never been documented.
The operation procedures are as follows:
Step 1: Skin incision was made along the infra cilia line.
Step 2: The inferior tarsal muscle of Mullers was stripped down from the lower tarsus and the conjunctiva.
Step 3: The Capsulopalpebral ligament was seperated from the septum.
Step 4: A 4-0 Dexon was passed through the mid-tarsus to the Capsulopalpebral ligament-Mullers muscle complex. The lower lid would be retracted downward. Two additional stitches were passed through the nasal side and the temporal side seperatively.
Step 5: Let the patient sit up to adjust the level of the lower lid.
Step 6: The skin wound was closed with 7-0 Ethilone.
