AIM
To evaluate the strain ratio of the optic nerve and retina-choroid-sclera (RCS) layers in individuals with physiological optic disc cupping (PC) and glaucoma patients using strain elastography.
MATERIAL AND METHODS
We evaluated 56 eyes of 56 subjects (20 eyes with glaucoma, 19 eyes with PC, and 17 normal eyes). The strain ratio of orbital fat to optic nerve (SROFON) was calculated as the ratio of the optic nerve to intraconal fat tissue and the strain ratio of orbital fat to retina-choroid-sclera (SROFRCS) was calculated as the ratio of RCS layers to intraconal fat tissue.
RESULTS
SROFON was 0.92 in the control group, 1.07 in the PC group and 1.6 in the glaucoma group and a statistically significant difference was present between the three groups (p<0.05). SROFRCS had no statistically significant difference between the three groups.
CONCLUSIONS
SROFON values could contribute to the differentiation of the patients with glaucoma and PC.
目的
使用应变弹性成像技术评估生理性视盘凹陷（PC）个体及青光眼患者视神经与视网膜-脉络膜-巩膜（RCS）层的应变率。
材料与方法
我们评估了56名受试者的56只眼睛（20只青光眼眼、19只PC眼和17只正常眼）。眼眶脂肪与视神经的应变率（SROFON）计算为视神经与锥内脂肪组织的比值，眼眶脂肪与视网膜-脉络膜-巩膜的应变率（SROFRCS）计算为RCS层与锥内脂肪组织的比值。
结果
对照组的SROFON为0.92，PC组为1.07，青光眼组为1.6，三组之间存在统计学显著差异（p<0.05）。三组之间SROFRCS无统计学显著差异。
结论
SROFON值有助于区分青光眼患者和PC患者。
