Abstract

The lamina cribrosa has been postulated from in vitro studies as an early site of damage in glaucoma. Prior in vivo measures of laminar morphology have been confounded by ocular aberrations. In this study the lamina cribrosa was imaged after correcting for ocular aberrations using the adaptive optics scanning laser ophthalmoscope (AOSLO) in normal and glaucomatous eyes of rhesus monkeys. All measured laminar morphological parameters showed increased magnitudes in glaucomatous eyes relative to fellow control eyes, indicating altered structure. The AOSLO provides high-quality images of the lamina cribrosa and may have potential as a tool for early identification of glaucoma.

摘要

从体外研究推测,筛板是青光眼早期损伤的部位。先前对板层形态的体内测量因眼像差而受到干扰。在本研究中,使用自适应光学扫描激光检眼镜(AOSLO)校正眼像差后,对恒河猴正常眼和青光眼眼中的筛板进行成像。所有测量的板层形态学参数显示,青光眼眼相对于对侧对照眼的数值增加,表明结构发生了改变。AOSLO能提供高质量的筛板图像,可能具有作为早期青光眼识别工具的潜力。
