Abstract Details


To research the relationship between Onset time(T) and Choroidal thickness(CT) in myopic patients by spectral-domain optical coherence tomography(SD-OCT).


Prospective clinical controlled study.


120 myopia patients (240 eyes) were divided into three groups:A Group(T= 5 year)、B Group(T=10 year)、C Group(T=15 year).There were no significant difference in equivalent power(F=1.54,P=0.26),age(F=2.11,P=0.17), best corrected visual acuity (BCVA) (F=1.42,P=0.31), corneal curvature(F=1.67,P=0.22) and axial length(F=1.90,P=0.18) between three groups. . CT at subfoveal (SFCT), 1 mm temporal (T1 mm), nasal (N1 mm), superior (S1 mm) and inferior (I1 mm) to the fovea and 3 mm temporal (T3 mm), nasal (T3 mm), superior (S3 mm) and inferior (I3 mm) to the fovea were recorded respectively.


The mean SFCT for A,B,C groups were (238.1±58.2)μm、(230.2±67.3) μm、(221.4±62.5) μm in this study.Between A group and B group,CT in all different locations were no significant difference ,except N3 mm(t A-B=4.32,P=0.032). Between B group and C group,CT in all different locations were no significant difference, except N3 mm(t B-C=7.65,P=0.023). Between A group and C group, CT in all different locations were significant difference, except T3 mm(t=0.77,P=0.29).Between A group and B group, B group and C group, A group and C group,there were significant difference in N3 mm(t A-B=4.32,t B-C=7.65,t A-C=12.11,P A-B =0.032, P B-C =0.023, P A-C =0.011).


The choroidal thickness was negatively correlated with onset time in myopia patients.
