摘要: | 乾眼症定義為因水樣淚液不足或成分不正確所引起的慢性角膜結膜的炎症
反應,同時也是伴侶動物常見的眼睛疾病,是影響動物生活品質與視力的原因之 一。局部點眼的環孢靈被認為是治療的首選,它被認為同時有減緩眼球表面的炎症反應與刺激淚液分泌等作用而達到治療的改善。本研究是以1999年10月至2007年2月間於台大動物醫院眼科門診就診的犬隻為族群所作的回溯性研究,以薛墨氏淚液測試為測量方式,主要的目的是可以獲得乾眼症在本教學醫院的發生概況,年齡,嚴重程度與不同品種間發病的臨床症狀來加以探討以及對健康的犬隻,探討影響淚液分泌量的因素。研究結果發現,對正常犬隻而言,淚液的分泌量會隨著年齡降低,性別與體重則不影響。另總共有224例乾眼症犬,其中201例為不明原因乾眼症,其中以Shih-tzu,American cocker spanial與Maltese犬占大多數,其中Maltese犬多發生早期的乾眼症,而Shihtzu犬則多很快進展為慢性乾眼症,同時此兩犬種角膜潰瘍的發生情形也較普遍。對於環孢靈的治療在本研究族群中約有70%不明原因乾眼症的患犬在6-8周的治療後有良好的治療反應。動物眼科疾病常是與品種相關的,而台灣地區乾眼症犬種的發生情況,也與文獻上提到的不盡相同,因此藉由回溯性調查可提供未來乾眼症發病與治療的參考。 Abstract Keratoconjunctivitis sicca (KCS, xerophthalmia) can be defined as a progressive inflammatory condition of the cornea and conjunctiva caused by lack of tears and deficiency of the precorneal tear film is commonly encountered in small animal practice. The topical cyclosporin is thought to be a gold standard treatment of KCS through both lacrimomimetic and anti-inflammatory effect. The aim of this study was to investigate the tear production in dogs with KCS, normal lacrimal function and efficacy of cyclosporin treatment in Taiwan. Data were obtained from the database of the Ophthalmology Section of the National Taiwan University Veterinary Hospital. Totally 344 dogs (26 breeds) were included in the study. In the group of dogs with normal lacrimal function (n=119), the value of Schirmer tear test (STT) was ranged from 15mm/min to 28mm/min and the mean STT1 value decreased with age. There was no significant difference in STT1 value in the aspects of patient’s weight, gender and side of eyes. In dogs with KCS (STT<15mm/min, n=201), there were represented in 22 breeds and American cocker spaniel, Shih-tzu and Maltese were the leading affected breeds. Mixed breed, Chihuahua and Shih-tzu showed significant variations in the onset age of KCS. There was a significantly higher incidence of ulcerative keratitis in KCS affected Shih-tzu and Maltese. 70% of KCS dogs treated with topical 1% cyclosporine solution showed a good response to the treatment. |
