AIM: To detect the macular ganglion cell complex thickness in monocular strabismus amblyopia patients, in order to explore the relationship between the degree of amblyopia and retinal ganglion cell complex thickness, and found out whether there is abnormal macular ganglion cell structure in strabismic amblyopia. <p>METHODS: Using a fourier-domain optical coherence tomography(FD-OCT)instrument iVue^&#xAE;(Optovue Inc, Fremont, CA), Macular ganglion cell complex(mGCC)thickness was measured and statistical the relation rate with the best vision acuity correction was compared Gman among 26 patients(52 eyes)included in this study. <p>RESULTS: The mean thickness of the mGCC in macular was investigated into three parts: centrial, inner circle(3mm)and outer circle(6mm). The mean thicknesses of mGCC in central, inner and outer circle was 50.74±21.51μm, 101.4±8.51μm, 114.2±9.455μm in the strabismic amblyopia eyes(SAE), and 43.79±11.92μm,92.47±25.01μm, 113.3±12.88μm in the contralateral sound eyes(CSE)respectively. There was no statistically significant difference among the eyes(<i>P</i>>0.05). But the best corrected vision acuity had a good correlation rate between mGcc thicknesses, which was better relative for the lower part than the upper part.<p>CONCLUSION:There is a relationship between the amblyopia vision acuity and the mGCC thickness. Although there has not statistically significant difference of the mGCC thickness compared with the SAE and CSE. To measure the macular center mGCC thickness in clinic may understand the degree of amblyopia.
