双眼视功能训练对间歇性外斜视患者术后双眼视功能重建的影响

目的：探讨双眼视功能训练对间歇性外斜视患者术后双眼视功能重建及维持术后眼位稳定的作用。

方法：收集2010-01/2015-12在我院行斜视手术的资料完整的间歇性外斜视患者142例,按术后是否进行双眼视功能训练分为治疗组(术后采用DV-100诊疗系统的三级视功能训练光盘针对双眼情况行同时视、融合功能及立体视功能光盘训练)和对照组(术后未行干预治疗)。分析两组患者术前、术后1、3、6mo,1a的斜视度数和双眼视功能情况,比较两组患者双眼视功能和眼位情况的差异。

结果：术后6mo,1a,治疗组的眼位情况好于对照组,差异均有统计学意义(P<0.05)。术后1、3、6mo,1a,治疗组的三级视功能均显著优于对照组,差异均有统计学意义(P<0.05)。

结论：间歇性外斜视患者通过手术获得眼位正位后,其双眼视功能可有一定程度恢复。术后通过视知觉学习,行双眼视功能训练,可以更快、更好地促进患者双眼视觉的恢复和重建,从而获得立体视觉,可以更好地稳定眼位,有利于减少术后眼位回退。

Effect of visual perception training on binocular visual function reconstruction in patients after strabismus surgery

AIM: To explore the effect of visual perception learning software training (VPT) on binocular visual function reconstruction in children with intermittent exotropia after strabismus surgery. METHODS: Ninety children with intermittent exotropia admitted to our hospital from June 2018 to December 2018 were included, and randomly divided into VPT and control groups. Children in the control group received basic binocular vision training, while those in the VPT group received VPT after strabismus surgery. Tertiary visual function, visual perception function, Newcastle Control Score (NCS), and ocular position retraction rate were compared at 3 and 12mo after the surgery. RESULTS: At 3 and 12mo after the surgery, the proportion of simultaneous perception, binocular fusion version and binocular stereo vision in the VPT group was conspicuously higher than that in the control group (P<0.05). After the vision training, the binocular visual perception functions of children in both groups were significantly improved compared with that before training (P<0.05). Interestingly, the grating sharpness, texture perception and texture motion perception in the VPT group were dramatically better than control group (P<0.01). The NCS in the VPT group was significantly lower than that in the control group (P<0.05). The ocular position retraction rate in the VPT group was significantly lower than that in the control group at 12mo (8.89% vs 26.67%, P=0.03). CONCLUSION: VPT effectively promotes binocular visual function reconstruction in intermittent exotropia children after strabismus surgery and reduces the strabismus severity and ocular position retraction rate.

Radiotherapy in thyroid eye disease: the effect on the field of binocular single vision.

PURPOSE: Thyroid eye disease (TED) can be a functionally disabling condition if ocular muscle involvement causes diplopia. The extraocular muscle restriction creates a reduced or eccentric field of binocular single vision (BSV). Orbital radiotherapy is now widely used in the treatment of TED, and although it has been reported as improving ocular motility, there have been few quantitative studies of the effect of treatment on ocular motor function. METHODS: Retrospective case note review of patients undergoing orbital radiotherapy for TED between 1992-1998 identified 79 case records. A total of 27 patients had diplopia in primary position or a significantly reduced binocular field before undergoing radiotherapy. The fields of BSV were analyzed pretreatment and at 3, 12, and 24 months after therapy to assess any improvement in function. We used the field of BSV as an outcome measure because it can be quantified and is a good indicator of functional ability. RESULTS: None of the 12 patients with double vision in primary position pretreatment regained a central binocular field with radiotherapy alone. Of the 15 patients with a central but reduced binocular field, 8 (53%) remained unchanged with treatment. In 4 patients (26.6%), there was an improvement in the field, while in 3 (20%) the field deteriorated. In all, 12 patients (44%) went on to require strabismus surgery. CONCLUSIONS: Orbital radiotherapy alone is ineffective in treating restrictive thyroid myopathy and improving binocular function.     

Disruption and reacquisition of binocular vision in childhood and in adulthood

PURPOSE OF REVIEW: This article reviews the most recent studies that address the loss of and restoration of binocular vision in childhood and adulthood and summarizes recent changes in treatment approaches. RECENT FINDINGS: Studies during the last two years support the idea of continued plasticity of the binocular visual system throughout life. Children and adults with strabismus onset following binocular vision maturation are susceptibility to a permanent disruption of stereopsis and sensory fusion. Plasticity of the binocular visual system, however, also means continued restorability of function. Despite a rather short critical time interval for restoration of normal function (three months in children and 12 months in adults), peripheral or extramacular binocular visual function can be restored in most patients whose onset of disruption follows binocular maturation. SUMMARY: Stereoacuity loss can occur in the visually mature patient who develops strabismus later in life and delay of treatment can be deleterious to the restoration of normal macular binocular vision. However, despite any delay of treatment, most patients with strabismus acquired following binocular vision maturation will manifest some stereoacuity or sensory fusion following eye realignment. These findings suggest all patients with strabismus need to have their eyes aligned, either surgically or optically, to maximize their binocular vision outcome.     

Binocular diplopia following vision restoration in patients with keratoconus and sensory strabismus

PURPOSE: To report the phenomenon of newly-noted binocular diplopia following vision improvement in patients with sensory strabismus secondary to keratoconus, and to document the effect of strabismus surgery on this diplopia. METHODS: Retrospective institutional case series [1982--2005] of records coded with keratoconus and strabismus. Keratoconus patients with visual acuity that could not be improved, childhood strabismus, known reason for acquired strabismus (other than decreased vision from kerataconus), decreased vision from other ocular disease, monocular diplopia, failure of strabismus surgery, and/or less than six months follow-up after strabismus surgery were excluded. RESULTS: Although 103 medical records were identified, only seven met the strict inclusion criteria. All seven patients presented with gradual reduction in vision (not due to their strabismus), and none initially complained of diplopia. After intervention to improve visual acuity, six complained of constant binocular diplopia. This diplopia resolved after successful strabismus surgery. Postoperative Worth four-dot testing demonstrated suppression. CONCLUSIONS: Binocular diplopia, noted after intervention to improve visual acuity in our patients with strabismus secondary to long-standing uncorrected keratoconus, resolved after successful surgical alignment. Our patients may have developed suppression from uncorrected keratoconus before their sensory strabismus occurred.     

Etiology and surgical management of horizontal pontine gaze palsy with ipsilateral esotropia.

INTRODUCTION: An esotropia ipsilateral to a horizontal pontine gaze palsy has been infrequently reported. We discuss the etiology and review the surgical management of this ocular motility defect. METHODS: Four patients with radiographically documented dorsal pontine lesions and persistent horizontal gaze palsy with esotropia ipsilateral to the gaze palsy were treated. In each patient, the esotropia was present in attempted primary gaze, producing symptomatic diplopia. An anomalous face turn was required to attain single binocular vision. RESULTS: All 4 patients underwent surgical correction to alleviate the anomalous head position and diplopia. Bilateral, asymmetric surgery was required to achieve a long-term successful result. Single binocular vision in the primary position with elimination or marked improvement of the compensatory head posture was initially achieved in all 4 patients. One patient, who had not undergone asymmetric strabismus surgery to reconcile incomitance produced by the esotropia, rapidly developed a residual esotropia. CONCLUSIONS: Ophthalmologists should recognize that concurrent esotropia may occur in patients with horizontal pontine gaze palsy. Single binocular vision in the primary position, an expanded binocular visual field, and alleviation of a compensatory head position are achievable with strabismus surgery.

Treatment of manifest latent nystagmus

Eight patients with manifest latent nystagmus, as noted by ocular movement recordings, were examined for nystagmus reduction after surgical or optical treatment. Seven of the patients had strabismus. Five patients underwent strabismus surgery, had no tropia postoperatively, and the manifest latent nystagmus converted to latent nystagmus. Four of these five patients subsequently showed improvement in binocular visual acuity. Three patients received optical treatment; one had accommodative esotropia and, with appropriate spectacle correction, the manifest latent nystagmus was converted to latent nystagmus with improved vision. In the other two patients the manifest latent nystagmus lessened after correction with appropriate spectacles; binocular visual acuity of one of these patients improved. The possibility of converting manifest latent nystagmus to latent nystagmus by strabismus surgery is a reasonable surgical goal. In patients with manifest latent nystagmus and strabismus, surgical or optical alignment of the eyes decreases the nystagmus intensity and may also improve binocular visual acuity.
