Abstract

PURPOSE: The effect of topical 2% taurolin therapy on ocular surface healing and adhesion formation was evaluated in rabbit alkali-burn model. METHODS: Alkali burns were induced by a 60's application of a filler paper (5x10 mm) soaked in 1 N Sodium hydroxide (NaOH) onto the ocular surfaces of both eyes including both bulber and palpebral conjunctiva and lower cornea of 9 rabbits. Animals were treated with 2% taurolin or the placebo (Balanced Salt Solution) solution 4 times daily for 35 days. The ocular surface was evaluated by slit-lamp biomicroscope daily, and the eyes of rabbits were enucleated for histopathologic evaluation at the end of therapy. RESULTS: All eyes developed fibropannus at the portion contacted with the filter stripe of cornea. Two eyes in each therapy groups developed forniceal obliteration, Also, 1 eye in taurolin group and 2 eyes in other group had mild entropion. In addition, 1 eye treated with BSS developed trichtasis. Histopathologic evaluation confirmed fibropannus on cornea and fibrosis formation on conjunctiva. CONCLUSIONS: We conclude that topical 2% taurolin solution 4 times in a day is not beneficial as antiadhesive agent on ocular surface after alkali-injury on ocular surface. The further studies are necessary concerning other therapeutic modalities such as topically more frequent doses or subconjunctival injection of taurolin.

Özet

AMAÇ; Tavşan alkali yanık modelinde %2'lik topikal taurolin tedavisinin oküler yüzeyde iyileşme ve yapışıklık oluşumu üzerindeki etkisi araştırıldı. YÖNTEM: 1 N sodyum hidroksite (NaOH) batırılmış filtre kağıtlarının (5x10 mm), 9 tavşanın her iki gözünün hem bulber hem de palpebral konjonktiva ve kornea alt kadranı ile temasa gelecek şekilde, 60 sn süre ile yerleştirilmesiyle alkali yanık oluşturuldu. Alkali yanıktan sonra tavşanların bir gözlerine %2'lik taurolin diğer gözlerine dengeli tuz solüsyonu (BSS) günde 4 defa olmak üzere 35 gün süreyle damlatıldı. Günlük olarak oküler yüzey biyomikroskopla değerlendirildi ve tedavi sonunda histopatolojik değerlendirme için gözler enüklee edildi. BULGULAR: Filtre kağıdı ile temas eden bütün gözlerin kornea alt kadranlarında kornea opak görünüm kazandı ve vaskülarize oldu (fibropannus). Taurolin alan 2 ve BSS alan 2 gözde konjonktival fornikste daralma saptandı. Yine taurolin ile tedavi edilen 1 ve BSS ile tedavi edilen 2 gözde hafif entropion gelişti. BSS ile tedavi edilen 1 gözde ise trikiazis gelişti. Histopatolojik değerlendirme, korneal yüzeydeki fibropannusu ve konjonktivadaki fibrozisi destekledi. SONUÇ: Alkali yanıktan sonra meydana gelebilen oküler yüzeydeki yapışıklıkları önlemede, topikal %2'lik taurolin'in günde 4 defa uygulanması etkili gözükmemektedir. Ancak taurolin'in topikal olarak daha sık damlatılması veya subkonjonktival enjeksiyonu gibi diğer tedavi yöntemleri yararlı olabilir.
