人类立体视功能的产生有诸多必要条件,双眼平行的视觉方向是其中之一。斜视后双眼的视觉方向不再平行,从而导致双眼视觉功能破坏;同时双眼视觉功能的丧失也意味着中枢对眼位的控制能力变差,进而促进斜视的发展。斜视的主要治疗方法是手术,术后患者可以达到双眼正位,但很多患者的双眼视觉功能并未恢复,一些患者还会由于双眼视觉功能的异常导致短期内斜视复发。因此,斜视的治疗不仅是手术达到双眼正位,术后双眼视觉的康复也同样重要。术后康复训练方法主要包括同视机双眼视觉康复训练、融合能力训练、电脑软件训练、视感知觉训练法等。人类大脑终身具有可塑性,如在术后双眼正位的情况下及时加以适当训练,帮助患者更好地恢复双眼视觉功能,加强大脑对双眼眼位的控制力,更好地保持术后双眼正位。(国际眼科纵览, 2018,  42:   179-183)  相似文献

目的了解双眼视觉训练对间歇性外斜视手术效果的影响。方法将45例间歇性外斜视患者以术后正位、欠矫、过矫分为三组,行术后双眼视觉训练,对三组训练前后的视远立体视锐度及最后眼位正位率进行观察比较。结果三组视远立体视锐度经双眼视觉训练后比术后2周时显著改善P〈0.01;最后眼位正位率三组间比较无显著差异P〉0.05;过矫组比欠矫组最后眼位正位率显著提高P〈0.05。结论双眼视觉功能训练对间歇性外斜视手术疗效和双眼视功能改善十分重要。术前有一定双眼视功能的患者术后早期的轻度过矫,加上双眼视觉训练将有利于达到远期眼位的正位与双眼视功能的发育。  相似文献

Purpose

To monitor the outcomes of surgical correction of esotropia in order to improve preoperative counselling for patients and their families.

Methods

A retrospective review audit of the medical charts at King Fahad Medical City. All patients treated surgically to correct esotropia, from January 2007 to December 2013. All operated cases were included regardless of age and esotropia etiology. The study used a goal-determined metric to assess the outcomes of strabismus surgery?>?6?months post-operatively, and on last follow-up. The risk factors for poor surgical outcomes were identified using a Pareto chart.

Results

A total of 99 cases with sufficient documentation to determine the surgical goal were included in the analysis. The goal was to improve eye contact (cosmetic correction) in 77.8% cases, to establish binocularity in 15.2% cases, to resolve diplopia for 4% cases, and to improve anomalous head posture for 3%. The overall outcome was excellent for 70.7% at the first follow-up and for 57.6% at the final visit. Simultaneous vertical muscle surgery and/or superior oblique muscle palsy were risk factors for poor outcome (odds ratio 3.15, 95% CI 1.11–8.99).

Conclusions

Excellent outcome of esotropia surgery in this study is comparable to outcomes reported internationally using the goal determined metrics. Quality improvement processes like the Pareto chart are simple to use and helpful for determining the risk factors associated with poor surgical outcomes after esotropia correction from different etiology.  相似文献

Purpose

To evaluate the result of re-operation on the deviated eye of recurred, consecutive or undercorrected sensory strabismus after surgery.

Methods

The medical records of 11 patients who had received second strabismus operation on the deviated eye due to recurred, consecutive or undercorrected sensory strabismus were studied retrospectively.

Results

Among the 11 patients, five patients were operated for recurred exotropia after surgery of sensory exotropia (group 1), two for consecutive exotropia after surgery of sensory esotropia (group 2), and four for undercorrected esotropia after surgery of sensory esotropia (group 3). Re-operation was performed 19.2±12.6 years after the first operation and the mean preoperative deviation before re-operation was 30.0±8.66 prism diopters (PD), 32.5±10.6PD, and 32.5±8.66PD, respectively. In all cases, a small amount of recession or resection compared with the usual surgical dosage was applied in re-operation on the deviated eye. The mean follow-up period after re-operation was 12.3±14.2 (1-48 months). Among the 11 patients, postoperative deviations less than 10PD were achieved postoperatively in 8 (72.7%) at 1 month and of the 8 patients with follow-up data beyond 6 months, 5 (62.5%) showed orthotropia within 10PD at 6 months or later.

Conclusions

The surgical result of re-operation on the deviated eye of recurred, consecutive or undercorrected sensory strabismus after the first surgery was satisfactory in spite of the reduced amount of surgical correction compared with the surgical dosage recommended for the non-operated eye.  相似文献

儿童斜视矫正术后的立体视觉   总被引:2,自引:0,他引:2  
本文报告168例儿童斜视术后有60例获得立体视觉,功能治愈率达35.7%。结果表明:斜视儿童术后立体视恢复与手术年龄、斜视度大小和术后眼位矫正程度等因素密切相关(P<0.01)。作者认为,手术时机的最佳选择取决于斜视类型和儿童初诊年龄。手术正位率是立体视重建和恢复的必不可少的因素。  相似文献

儿童部分调节性内斜视的手术矫正与立体视觉   总被引:7,自引:0,他引:7  
为探讨儿童部分调节性内斜视的手术时机,观察了78例儿童部分调节性内斜视矫正术后的立体视恢复情况;分析各种因素对其立体视恢复的影响。结果:78例中,55例术后获得立体视,功能治愈率为70.5%,且术后立体视的恢复率与术前相比,差异非常显著(p<0.01);早期手术组及具有融合功能组的立体视的恢复率显著高于较晚手术组及无融合功能组(p<0.01);发病越早,术后建立立体视的预后越差。结论:儿童部分调节性内斜视与部分调节因素有关,其由于解剖因素所引起的斜视需手术矫治。从立体视恢复上考虑,当患儿全矫配镜半年眼位仍不能正位时,应尽早手术矫正其残存的内斜度。术中应根据戴全矫眼镜后的眼位决定手术量。术后由于调节因素所致的内斜视仍需配镜矫正。  相似文献

Purpose

To evaluate the outcomes of one muscle recession for horizontal comitant strabismus at a major referral hospital in the Middle East.

Method

Retrospective charts review of postoperative outcomes of 90 patients who had undergone one muscle recession for small to moderate angle esotropia or exotropia. Data were collected for age, vision, amblyopia, previous surgery or botulinum toxin injection, preoperative deviation, amount and type of one muscle surgery, and postoperative deviation at the initial and last (six months or more) postoperative visit. Successful alignment was defined as ±10 prism diopters (PD) of orthophoria.

Results

Sixty patients underwent medial rectus recession and 30 patients underwent lateral rectus recession. The average preoperative and last follow up deviation -respectively- was 24?±?6.1 PD (15–35) PD and 14.62?±?8.91 PD in the medial rectus recession group and 21.3?±?5.1 PD (12–30) and 12.60?±?8.74 in the lateral rectus recession group. The final success rates were 63.3% in both groups.

Conclusion

Single muscle strabismus surgery to correct horizontal strabismus had a variable outcome. Larger recession may help in achieving better outcomes. Properly designed prospective studies may help in identifying the factors affecting the outcomes of single muscle strabismus surgeries.  相似文献

Background

To investigate the incidence of and factors predisposing to consecutive esotropia after intermittent exotropia surgery, and to prevent the onset of consecutive esotropia.

Methods

We retrospectively surveyed 226 patients who had been followed up for more than 1?year after surgery for intermittent exotropia conducted between February 2005 and September 2010. Consecutive esotropia was defined as an esotropia of at least 10 prism diopters (PD) at distance or near at least once in 2?weeks after surgery. Presumed risk factors for consecutive esotropia were analyzed. Gender, age at surgery, average binocular spherical equivalent, anisometropia, high myopia, amblyopia, preoperative angle of deviation, vertical deviation, A-V pattern strabismus, exotropia type, type of surgery, stereopsis, and suppression were investigated to evaluate factors influencing the onset of consecutive esotropia.

Results

Consecutive esotropia occurred in 22 patients (9.7?%). Significant correlations with occurrence of the condition were found with high myopia (P?=?0.013), amblyopia (P?=?0.047), preoperative angle of deviation of 25–40 PD at distance (P?=?0.016), deviation at distance – deviation at near > 10 PD (P?=?0.041), lateral incomitance (P?=?0.007), tenacious proximal convergence fusion type (P?=?0.001), unilateral lateral rectus muscle recession and medial rectus muscle resection (P?=?0.001).

Conclusions

High myopia, amblyopia, and lateral incomitance were predisposing factors for consecutive esotropia. Furthermore, the preoperative angle of deviation at distance, differences between the angle of deviation at near and at distance, the type of intermittent exotropia, and the type of surgery affected the incidence of consecutive esotropia. More attention must be paid to patients with such factors.  相似文献
