Abstract

Purpose: To evaluate changes in intraocular pressure (IOP) at different gaze positions before and after superior rectus muscle-lateral rectus muscle (SR-LR) loop myopexy in highly myopic strabismus (HMS).

Study design: Nonrandomized clinical, prospective, interventional trial.

Methods: Fourteen patients with HMS (18 eyes) who underwent SR-LR loop myopexy were divided into 3 groups: < 100 prism diopters (PD) (mild esotropia [ET] group), > 100 PD (large ET group), and > 100 PD, and simultaneous recession of the medial rectus (MR) muscle was performed (large ET + MR group). Intraocular pressure was measured preoperatively and postoperatively at the primary, abduction, and adduction positions in each group.

Results: Intraocular pressure did not change after surgery in the mild ET group. Intraocular pressure significantly decreased in the abduction position (from 20.0 ± 2.1 to 16.0 ± 1.9 mmHg, P = 0.043) in the large ET group and in the abduction (from 22.2 ± 5.9 to 15.6 ± 4.3 mmHg, P = 0.048) and primary positions (from 15.8 ± 5.0 to 10.2 ± 2.8 mmHg, P = 0.043) in the large ET + MR group. The preoperative significant differences in IOP between the abduction and adduction positions in the large ET group (7.4 ± 3.4 mmHg) and the large ET + MR group (10.0 ± 5.5 mmHg) disappeared postoperatively (3.2 ± 2.8 mmHg and 3.6 ± 1.7 mmHg, respectively). The differences in IOP between abduction and adduction were similar in all the groups.

Conclusion: SR-LR loop myopexy decreased IOP in patients with HMS in the abduction and primary positions.

高度近视斜视上直肌-外直肌环近视后不同凝视体位的眼压变化。

目的:探讨高度近视斜视(HMS)患者上直肌-外直肌(SR-LR)环近视术前后不同凝视位置眼压(IOP)的变化。研究设计:非随机临床、前瞻性、干预性试验。方法:14例HMS患者(18眼)行SR-LR环肌固定术，分为100 PD组(大ET组)和100 PD组(大ET + MR组)，同时行内侧直肌(MR)收缩术。各组术前和术后分别在原发、外展和内收位置测量眼压。结果:轻度ET组术后眼压无明显变化。大ET + MR组外展位眼压(从20.0±2.1降至16.0±1.9 mmHg, P = 0.043)和外展位眼压(从22.2±5.9降至15.6±4.3 mmHg, P = 0.048)和原发位眼压(从15.8±5.0降至10.2±2.8 mmHg, P = 0.043)均显著降低。术前大ET组(7.4±3.4 mmHg)和大ET + MR组(10.0±5.5 mmHg)外展位和内收位IOP的显著差异在术后(分别为3.2±2.8 mmHg和3.6±1.7 mmHg)消失。外展和内收的IOP差异在所有组中相似。结论:外展位和原发位HMS患者的SR-LR环闭锁可降低IOP。

期刊介绍： The Japanese Journal of Ophthalmology (JJO) was inaugurated in 1957 as a quarterly journal published in English by the Ophthalmology Department of the University of Tokyo, with the aim of disseminating the achievements of Japanese ophthalmologists worldwide. JJO remains the only Japanese ophthalmology journal published in English. In 1997, the Japanese Ophthalmological Society assumed the responsibility for publishing the Japanese Journal of Ophthalmology as its official English-language publication. Currently the journal is published bimonthly and accepts papers from authors worldwide. JJO has become an international interdisciplinary forum for the publication of basic science and clinical research papers.
