Abstract:
Objeetive To investigate the detection of hemodynamiCS parameters of conjunctival microvessels by functional slit lamp biomicroscopy (FSLB) in normal adult and its clinical application values.Methods Randomly selected 16 postgraduate students aged 21 to 25 years from the Nanchang University and Zhongshan Ophthalmic Center,including 8 males and 8 females.The density,length and diameter of conjunctival microvessel and the flow velocity of arteriolar and venular blood were measured by FSLB and software program (BenoitTM,TruSoft Inc,St.Petersburg,FL,USA),as well as the indicators' characteristics of the subjects' were analyzed.Results As for subjects' right eyes,the microvascular density,length,diameter,and the arteriolar and venular blood flow velocity were no significant difference between the upper,and lower sides,as well as between nasal and temporal sides (all P ＞ 0.05);meanwhile the microvascular density,length and diameter of the upper and lower sides were both lower than those of the nasal and temporal sides,and the differences were statistically significant (all P ＜ 0.05),while the arteriolar and venular blood flow velocity of the upper and lower sides were both significantly higher than those of the nasal and temporal sides,and the differences were statistically significant (all P ＜ 0.05).In addition,the changes in hemodynamics parameters of conjunctival microvessels of the left eyes and total eyes in subjects were consistent with the right eyes.Conclusion FSLB can clearly obtain hemodynamics parameters of conjunctival microvessels in healthy grown-ups,and has a promising clinical value.
