Biz sürekli oküler hipertansiyon üzerinde rapor fare gözünde lazer aydınlatma ile uyarılabilir. Tuzlu enjeksiyon modeli 18 ve damar koter modeli geniş mikrocerrahi beceri gerektiren her ikisi de 11 ile karşılaştırıldığında, lazer aydınlatma gerçekleştirmek için oldukça basit ve kolaydır. Genellikle 2-3 saat içinde 4-6 fareler için lazer aydınlatma gerçekleştirebilirsiniz. Sürekli GİB artışı elde etmek için önemli adımlar lazer aydınlatma için lazer ve parametrel...

a laser-induced mouse model of chronic ocular hypertension to characterize visual defects

Sık sık yüksek göz içi basıncı (GİB) ile ilişkili Glokom, körlüğün önde gelen nedenlerinden biridir. Biz insan yüksek gerilim glokom taklit etmek oküler hipertansiyon bir fare modeli kurmak için çalıştı. Burada, lazer aydınlatma açı kapanması neden olan, sulu bir çıkış photocoagulate için kornea limbusa uygulanır. GİB değişiklikler lazer tedavi öncesi ve sonrası bir canlanma tonometre ile izlenmektedir. Bir optomotor davranış testi görsel kapasitesi karşılık gelen değişiklikleri ölçmek için kullanılır. Lazer aydınlatma sonra sürekli GİB yükselmesi geliştirilen bir fare temsilcisi sonucu gösterilir. Bir azalmış görme keskinliği ve kontrast duyarlılık bu göz hipertansif fare görülmektedir. Birlikte, Çalışmamızda glokom farelerde nöronal dejenerasyon ve altta yatan moleküler mekanizmaları araştırmak için değerli bir model sistem tanıttı.

Gibi prosedürler tarif, lazer aydınlatma açı kapanması (Şekil 1) uyaran, sulu çıkış photocoagulate için limbal bölgede trabeküler ağ hedefleniyor. En Lazerli göz önceki bulgularla 6 tutarlı anlamlı fiziksel hasar, pigment dekolmanı ya da enfeksiyon, sergiledi. Farelerin küçük bir grup (tüm Lazerli hayvanların% 5&#39;inden az) gibi sönük göz topları, ağır katarakt, önemli pigment dekolmanı veya kanama gibi ciddi hasar fiziksel belirtileri sergiledi, biz hemen on...
