Innovative applications of clinical ocular diagnostic tools are emerging to help identify systemic disorders that extend beyond ocular diseases. Ophthalmodynamometry (ODM) is a screening tool that non-invasively determines mean central retinal artery pressure (MCRAP) and ocular perfusion pressure (OPP). Decreased OPP and MCRAP on Falck Medical Multifunctional Device (FMD, Falck Medical, Inc., Mystic, CT), along with reverse ophthalmic artery flow (ROAF) on transcranial Doppler ultrasonography (TCD), indicate increased collateral brain perfusion and possible stenosis of the ophthalmic artery or internal carotid artery (ICA). In this case report, we describe the case of a 78-year-old female with ROAF, reduced MCRAP, and OPP in the right eye, confirmed by carotid duplex of 50-79% right ICA stenosis. Early application of ODM and TCD allowed for prompt diagnosis and management with a vascular specialist.
临床眼科诊断工具的创新应用正在兴起，以帮助识别超出眼部疾病范围的全身性疾病。眼血流动力学测量法（ODM）是一种非侵入性测定视网膜中央动脉平均压（MCRAP）和眼灌注压（OPP）的筛查工具。Falck医疗多功能设备（FMD，Falck医疗公司，康涅狄格州神秘市）上的OPP和MCRAP降低，以及经颅多普勒超声检查（TCD）上的眼动脉反向血流（ROAF），表明侧支脑灌注增加以及眼动脉或颈内动脉（ICA）可能存在狭窄。在本病例报告中，我们描述了一名78岁女性的病例，其右眼存在ROAF、MCRAP降低和OPP降低，经颈动脉双功超声检查证实右侧ICA狭窄50 - 79%。早期应用ODM和TCD使得能够及时由血管专科医生进行诊断和管理。
