臨床評估結膜鬆弛與溢淚二者之關係

本文收集三總自民國77年2月至78年2月，共8例16眼結膜鬆弛症(conjunctivochalasis)患者，平均年齡67歲，男性3位女性5位，主要主訴為流淚，經手術切除贅餘鬆弛之結膜4至6週後有87%（14/16眼）病人自覺流淚情況獲得改善，13%（2/16眼）病人流淚情況未獲得改善。同時我們也利用一種具有動態性(dynamic)，生理性(physiologic)而無侵犯性(non-invasive)的淚器核醫掃描檢查(nuclear dacryocystography)來測得手術前後T(二分之一)值。T(二分之一)值改善之患者其流淚之症狀大多獲得改善，由此確知結膜鬆弛症是溢淚的主要原因之一。它造成溢淚的主要機轉是(一)機械性阻礙了淚液的流向。(二)鬆弛的結膜直接履蓋在下淚點開口處。

From February 1988 to February 1989, we had collected 8 cases (16 eyes) of conjunctivochalasis with chief complaint of epiphora. the average age was 67 years old, three man and five female, every patient was followed 4 to 6 weeks after redundant conjunctival tissue was resected. 87% of eyes (14/16 eyes) felt improvement of tearing, 13% of eyes (2/16 eyes) felt no significant improvement postoperatively. At the same time, we used a dynamic, physiologic, and noninvasive method of nuclear dacrocystography (microscintigraphy) to compare the T(l/2) (median transit time) preoperation and postoperation. It causes epiphora by mechanically disrupting the normal meniscus and/or flow of the tear, or directly over the punctum, blocking the entrance of the tear drainage system.
