To explore the relationship between eyeball structure and visual acuity in high myopia.
Totally, 152 people (283 eyeballs) with different levels of myopia were tested for visual acuity, axial length, and fundus. All cases were classified according to diopter, axial length, and fundus. The relationships between diopter, axial length, fundus and visual acuity were studied. The mathematical models were established for visual acuity and eyeball structure markers.
The visual acuity showed a moderate correlation with fundus class, comus, axial length and diopter ([r] > 0.4, P < 0.000 1). The visual acuity in people with the axial length longer than 30.00 mm, diopter above -20.00 D and fundus in 4th class were mostly below 0.5. The mathematical models were established by visual acuity and eyeball structure markers.
The visual acuity should decline with axial length extension, diopter deepening and pathological deterioration of fundus. To detect the structure changes by combining different kinds of objective methods can help to assess and to judge the vision in high myopia.
探讨高度近视患者眼球结构与视力之间的关系。
对152例（283只眼）不同近视程度的患者进行视力、眼轴长度及眼底检查。所有病例均根据屈光度、眼轴长度和眼底进行分类。研究屈光度、眼轴长度、眼底与视力之间的关系。建立视力与眼球结构指标的数学模型。
视力与眼底分级、视盘、眼轴长度和屈光度呈中度相关（[r]>0.4，P<0.000 1）。眼轴长度大于30.00 mm、屈光度高于-20.00 D且眼底为4级的患者，其视力大多低于0.5。通过视力和眼球结构指标建立了数学模型。
随着眼轴长度延长、屈光度加深及眼底病变加重，视力应下降。联合多种客观方法检测结构变化有助于评估和判断高度近视患者的视力。
