摘要
Functional slit lamp biomicroscopy(FSLB)is a novel device which consists of a traditional slit-lamp and a digital camera.It can quantitatively assess vessel diameter,blood flow velocity,and blood flow rate and can create noninvasive microvascular perfusion maps(nMPMs).At present,FSLB is mainly used in contact lens(CL)and dry eye disease(DED)studies to advance our understanding of ocular surface microcirculation.FSLB-derived blood flow and vessel density measures are significantly altered in CL wearers and DED patients compared to normal people.These subtle changes in the ocular surface microcirculation may contribute to the monitoring of potential diseases of the body and provide a new way to diagnose dry eye disease.Therefore,this may also indicate that FSLB can be more widely applied in the study of other diseases to reveal the relationship between changes in ocular surface microcirculation and systemic diseases.The purpose of this paper is to summarize the functions of FSLB and the related studies especially in CL and DED.
