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

자주 높은 안압 (IOP)와 관련된 녹내장은 실명의 주요 원인 중 하나입니다. 우리는 인간의 높은 안압 녹내장을 모방하는 안구 고혈압의 마우스 모델을 구축하기 위해 노력했다. 여기에 레이저 조명은 각 폐쇄를 유도 수성 유출 photocoagulate하기 위해 각막 윤부에 적용됩니다. IOP의 변화는 레이저 치료 전후 리바운드 안압계를 사용하여 모니터링 할 수 있습니다. optomotor 행동 테스트는 Visual 용량의 해당 변화를 측정하는 데 사용됩니다. 레이저 조명 후 지속적인 안압 상승을 개발 한 마우스에서 대표적인 결과가 표시됩니다. 시력 저하 및 대비 감도는이 안구 고혈압 쥐에서 관찰된다. 함께, 우리의 연구는 녹내장 쥐에서 신경 세포의 변성 및 기본 분자 메커니즘을 조사하기 위해 중요한 모델 시스템을 소개합니다.

절차에서 설명한대로, 레이저 조명은 폐쇄 각 (그림 1)을 유도, 수성 유출 photocoagulate하는 각막 윤부 지역에서 섬유주위한 것입니다. 대부분의 레이저로 눈 앞의 연구 결과 6 일치 유의 물리적 손상, 색소 분리 또는 감염을 전시하지 않습니다. 쥐의 작은 그룹 (모든 레이저로 동물의 5 % 미만)은 수축 눈 공, 심한 백내장, 중요한 색소 분리, 또는 출혈 등 심각한 손상의 물리적 흔?...
