Scheimpflug photography is the basis for a variety of imaging devices that are highly versatile. The applications of Scheimpflug imaging are wide in scope, spanning from evaluation of corneal ectasia to quantifying density in nuclear sclerotic cataracts. The potential uses for Scheimpflug-based devices are expanding and a number of them are relevant in glaucoma. In particular, they can provide three-dimensional image reconstruction of the anterior segment which includes assessment of the iridocorneal angle. Photographic analyses allow also for a noncontact method of estimating central corneal thickness (CCT) and intraocular pressure (IOP), as well as the study of various corneal biomechanical properties, which may be useful for stratifying glaucoma risk.
Scheimpflug摄影术是多种高度通用的成像设备的基础。Scheimpflug成像的应用范围广泛,从角膜扩张的评估到核性硬化性白内障密度的量化。基于Scheimpflug的设备的潜在用途正在不断扩展,其中一些在青光眼方面具有相关性。特别是,它们可以提供眼前节的三维图像重建,包括对虹膜角膜角的评估。摄影分析还允许采用非接触方法来估计中央角膜厚度(CCT)和眼压(IOP),以及研究各种角膜生物力学特性,这可能有助于对青光眼风险进行分层。
