To investigate the clinical applicability of a physical principle that suggests that a large globe offers less resistance to applanation than a smaller one.
Referral practice, Bridgeport, Connecticut, USA.
The correlation between axial length and applanation tonometry in 513 adult eyes, arbitrarily chosen from a referral practice, was examined using regression analysis.
A statistically significant negative correlation was found; that is, for every 1.0 mm increase in axial length, the tonometry value was 0.29 units lower (P =.0002). In women, the mean axial length was 1.04 mm shorter and the mean intraocular pressure 0.54 mm Hg higher than in men.
Globe size influenced applanation tonometry readings. Hence, when the tonometry record does not fit the clinical findings, axial length measurement may help interpret its significance.
研究一项物理原理的临床适用性，该原理表明大眼球比小眼球对压平的阻力更小。
美国康涅狄格州布里奇波特的转诊诊所。
从转诊诊所中随机选取513只成人眼睛，使用回归分析检查眼轴长度与压平眼压测量法之间的相关性。
发现存在具有统计学意义的负相关；也就是说，眼轴长度每增加1.0毫米，眼压测量值就降低0.29个单位（P = 0.0002）。女性的平均眼轴长度比男性短1.04毫米，平均眼压比男性高0.54毫米汞柱。
眼球大小影响压平眼压测量读数。因此，当眼压测量记录与临床发现不符时，测量眼轴长度可能有助于解释其意义。
