To analyze the relationship between changes in the intraocular pressure (IOP) and dislocation angle in highly myopic strabismus patients who had undergone muscle union surgery.
Medical data were examined of eight eyes of seven consecutive patients with highly myopic strabismus, who had some limitation in abduction, received muscle union surgery and undergone pre- and postoperative IOP evaluation with a noncontact tonometer, and were retrospectively reviewed. In addition, 15 eyes of 15 patients with comitant horizontal strabismus who underwent unilateral recess-resect procedure as well as pre- and postoperative IOP evaluation were also included. The correlation between IOP changes after strabismus surgery and the dislocation angle of the globe was analyzed.
The IOP was significantly reduced in the highly myopic strabismus group (-5.6 mmHg) but not in the fellow eye or in comitant horizontal strabismus patients. The decrease in IOP after surgery was significantly correlated with the preoperative dislocation angle of the globe (r = -0.725, p = 0.042).
IOP is often higher in highly myopic strabismus patients than perceived, and it may indicate abnormal anatomy of the orbit rather than glaucoma. In that case, muscle union surgery can improve eye position and normalizes the IOP.
分析接受肌肉联合手术的高度近视斜视患者眼压（IOP）变化与眼球脱位角度之间的关系。
回顾性分析连续7例高度近视斜视患者的8只眼的医学资料，这些患者外展有一定受限，接受了肌肉联合手术，并使用非接触眼压计进行了术前和术后眼压评估。此外，还纳入了15例共同性水平斜视患者的15只眼，这些患者接受了单侧后徙-切除手术以及术前和术后眼压评估。分析斜视手术后眼压变化与眼球脱位角度之间的相关性。
高度近视斜视组眼压显著降低（-5.6 mmHg），但对侧眼或共同性水平斜视患者眼压未降低。术后眼压降低与术前眼球脱位角度显著相关（r = -0.725，p = 0.042）。
高度近视斜视患者的眼压通常比预期的要高，这可能表明眼眶解剖结构异常而非青光眼。在这种情况下，肌肉联合手术可以改善眼位并使眼压恢复正常。
