摘要

近視眼之眼球靱度較正常眼低，似平已成不爭之事實，而近視眼之眼壓似平比正常眼為高。日本人曾統計近視眼之房水排出速率係數（C值）較正常眼低。本文乃利用電腦化電動眼壓繪記法(Computerized Tonography)對近視眼之眼球靱度，眼壓及房水排出速率重新加以檢討。結果近視眼之眼球靱度係數平均0.018±0.002，正視眼平均0.020±0.003，近視眼之眼球靱度較正常眼低，其差異具統計學上之意義。近視眼之眼壓平均14.452±1.765 mmHg，正視眼平均13.795±1.470 mmHg，近視眼之眼壓較正視眼高，其差異却無統計學上之意義。近視眼之C值平均0.260±0.108 μ1/min•mmHg，正視眼平均0.234±0.114μ1/min•mmHg，近視眼之C值較正視眼高，其差異亦為統計學上之意義。

The intraocular pressure, ocular rigidity and outflow facility of myopia are studied by use of computerized tonography. The results reveal that the ocular rigidity is lower in myopia than in emmetropia, with statistical significance. The ocular rigidity does not decrease progressively as the degree of myopia increases. There is no difference of ocular rigidity among different age groups of emmetropia.
The intraocular pressure of myopia is higher than that of emmetropia, but without statistical significance. A positive correlation between axial length and intraocular pressure had been reported. In this study, however, a negative correlation is found between these two factors. A progressive lowering of intraocular pressure is noted as the age of emmetropes increase, which is quite different from the other reports.
There is no reduced C value (coefficient of outflow) in myopia. And the results show no negative correlation between the C value and axial length in this study.
