Abstract:
Objective To analyze the correlation of the macular retinal ganglion cells-inner plexiform layer (GCIPL) thickness and the axial length and refractive power in myopia,thereby providing guidance for GCIPL thickness analysis in myopic glaucoma patients.Methods A total of 95 patients (190 eyes) with different degrees of myopia were recruited from October 2015 to September 2016 in Shenyang HE Eye Hospital,with age ranging from 18 to 36 years.Variables including gender,age,axial length,medical optometry diopter (spherical equivalent),GCIPL thickness (the mean,minimum,superior,inferior,temporal superior,temporal inferior,nasal inferior and nasal superior parameter) were recorded.According to diopter,all patients were divided into A group (-0.25 to-3.00D),Bgroup (-3.25 to-6.00 D),C group (＞-6.00 D);moreover,according to the axial length,they were assigned into A1 group (22 to 24 mm),B1group (＞24 to 26 mm) and C1 group (＞26 mm),and all above variables were compared.Single factor analysis of variance was used to analyze the differences in GCLIP thickness parameters between the 3 groups and Pearson correlation analysis was used to analyze the correlation of GCIPL thickness with different diopters and axial length.Results There was no significant difference in gender and age,but there were significant differences in the mean diopter and axial length among the 3 groups (F =523.963,P =0.000;F =57.452,P =0.000).And a negative correlation was presented between axis length and refractive power (r =-0.707,P =0.000) in all patients.There were significant differences in GCIPL thickness (the mean,minimum,superior,inferior,temporal superior,temporal inferior,nasal inferior and nasal superior parameter) among A,B and C group (F =3.231-16.500,all P ＜ 0.05) as well as among A1,B1 and C1 group (F =5.234-19.999,all P ＜ 0.05).The thickness of GCIPL was negatively correlated with refraction power (r =-0.419 to-0.153,all P ＜ 0.05),and the axial length(r =-0.407 to-0.241,all P ＜ 0.05).Conclusion With the increase of diopter and axial length,the thickness of GCLIP gets thinner in myopic patients.The effect of axial length should be taken into consideration when the GCLIP thickness of myopic glaucoma patients is evaluated.
