高度近视眼底形态学与视力关系的研究
Relationship between visual function and morphological changes of the high myopia fundus
摘要
Abstract
AIM: To evaluate the morphological changes of peripapillary atrophy ( PPA) and retinal thickness ( RT) in high myopia under different best corrected visual acuity ( BCVA) . <br> METHODS: A retrospective review of medical records in 55 high myopia patients (104 eyes) was carried out, whose spherical equivalent ( SE) refractive errors ranged from - 6 ~ - 27D. Groups A, B and C were divided according to different BCVA. The parameters including optic disc ( OD) size, PPA size, the biggest width of OD along the horizontal axis, the biggest width of PPA along the horizontal axis, the size of the peripapillary chorioretinal atrophy ( PCA), the average 6mm center retinal thickness ( ACRT ) , the center retinal thickness (CRT), the total 6mm center retinal volume ( TCRV) were evaluated. All the data were analyzed respectively by one-way ANOVA with edition SPSS 13. 0. <br> RESULTS: There were significant differences among three groups on PPA size (8. 29±4. 82, 4. 31±3. 05, 2. 49±2.60mm2 in groups A, B and C, respectively), PPA width (1. 88±0. 83, 1. 31±0. 66, 0. 86±0. 61mm in groups A, B and C, respectively) (all P<0. 01). The PCA size was increased significantly in group A (4. 26±4. 27mm2 ) than other groups (group B:1. 23±1. 74mm2, group C:0. 62±1.53mm2) (F=19. 58, P<0. 01). The OD size and width had no significant differences among three groups ( F=1.1, P = 0. 33; F = 0. 44, P = 0. 64 ). ACRT and TCRV reduced significantly in group A ( ACRT: 211. 34 ±118.32μm;TCRV:6. 09±3. 65mm3 ) than in other groups (F=4. 28, P=0. 01; F=3. 35, P=0. 03), but no significant difference between groups B and C. CRT was not changed in three groups (F=2. 23, P=0. 11). <br> CONCLUSION: PCA increase, ACRT and TCRV decrease assist to evaluate visual function in high myopia. PPA increase indicates the myopia progress.关键词
