Abstract
ObjectiveTo explore the feasibility and the value of ultrasound transient elastography in the estimation of intraocular pressure.
MethodsThirty-two cases of glancomatous patients' and twenty-eight healthy subjects' eyeball were examined by using ultrasound transient elastography, meanwhile using Photoshop image analysis software to quantitative analysis of blue gradation ratio of the front wall tissue of eyeball, then intraocular pressure were examined by NCT. The difference of quantitative data of blue gradation ratio of the front wall tissue of eyeball between glancomatous patients and healthy subjects were compared. The relationship of quantitative value of blue gradation ratio and intraocular pressure were established.
ResultsThe blue gradation ratio of the front wall tissue of eyeball in glancomatous patients were 0.37±0.03, while in healthy subjects were 0.33±0.02, there was a significant difference between glancomatous patients and healthy subjects (P<0.01), and there was a linear relation between blue gradation ratio and intraocular pressure(r=0.424, P<0.05).
ConclusionsThe ultrasound transient elastography can be used in estimation of intra-ocular pressure in glancomatous patients, and there is a linear relation in quantitative data between blue gradation ratio and intraocular pressure.
