Description

A kind of system that adopts regulation and control ocular dominance treatment visual function disorder
Technical field
The present invention relates to a kind of visual stimulus software system of regulating and control eyes advantage balance.Specifically can be applicable to improve and treat comprise the various of amblyopia because the unbalanced visual function disorder that causes of stereopsis vision input.
Background technology
People's binocular stereo vision is to form like this: eyes are watched object simultaneously attentively, the eyes sight line intersects at a bit, be point of fixation (Fixation Point), the luminous point about reflecting back into from point of fixation on two eyes retinas claims corresponding point (corresponding point).Because there is spacing (meansigma methods is 50-75mm) in two pupils of people, therefore for same scenery, the relative position of right and left eyes (Relative Position) is different, and this has just produced binocular parallax (Binocular Disparity), and what namely right and left eyes was seen is discrepant image.This visual information from eyes changes the primary vision cortex over to through lateral geniculate body, makes the people obtain an image with stereoscopic depth of perception after visual centres at different levels are handled integration again.Specifically, in case eyes focus on point of fixation, not only seen this point clearly, and this point and the distance between object, the degree of depth, convex-concave, contrast, aberration, profile etc. can both distinguish on every side, this perceived to visual pattern be exactly 3 D visual image, people's this binocular stereo vision function is called for short stereoscopic vision (Stereopsis).
The depth perception that stereoscopic vision makes the people have the perception in the indirect vision world.Specifically, eyes have perception (Depth Perception) to the degree of depth of the external image that captures, can extract depth information (Depth Cue) in the scene and this ability is based on left and right sides eyes.Why human eye can possess these abilities, mainly relies on following 4 kinds of basic functions of eyes:
1. visual disparity (Binocular disparity)
That visual disparity is described owing to have distance between two, the image of object drops on the difference of the position appearance of retina of both eyes when right and left eyes is watched same object attentively.Utilize visual disparity to extract 2 depth informations of tieing up in the retinal images at the stereoscopic vision deutocerebrum.
As shown in Figure 1, wherein 1 represents horopter, the 2 expression optical axis, if two (Horopter) point of fixation A that focus on the horopter are projected at the optical axis angle of left and right sides retina epigraph when going up with B the same big, be respectively L and R, two eyes retina epigraphs are overlapping in other words, do not have parallax.But when one of two focus point be point of fixation A on horopter and another project when focusing on the binocular single vision point of fixation C out-of-bounds the optical axis angle of left and right sides retina epigraph different big be respectively L ' and R '.At this moment the position of the left and right sides retina epigraph difference appears and can't be overlapping, parallax forms.
As shown in Figure 2, when a binocular fixation point is at (A) on the horopter and another point of fixation is when near-sighted point (Near point), forms and intersect parallax (Crossed Disparity).Produce object near observer's stereopsis consciousness.Otherwise, when a binocular fixation point is at (C) on the horopter and another point of fixation is when High eye point (Far point), form non-intersection parallax (Uncrossed Disparity).Produce the stereopsis consciousness that object leaves the observer.
2. adapt (Accommodation)
The adapt of eyes mainly refers to the behavior of initiatively focusing (focusing action) of eyes.Mainly be applicable to closely focusing.The focal length of eyes carries out meticulous adjusting by changing intra-ocular lens (Lens) curvature.When watching attentively on certain object, the variation that the curvature of intra-ocular lens takes place makes eyes realize focusing on and sees far and near different object and the different parts of same scenery clearly.And being contraction and diastole by its attached Jie shape flesh, lenticular adjusting realizes.
3. eyes converge (Convergence)
Direction by binocular fixation is determined depth preception.Your eyes sight line shape in an angle when you watch certain object attentively.When object from you more close to this angle just more big, when object from you more away from this angle just more little.When object from you more and more away from the sight line trend of eyes parallel.
4. mobile parallax (Motion dispairy)
It is to realize by the relative motion between observer and the observed object that Parallax produces depth perception.You can only observe by one and examine the external world so to close an eye.When you stretch out thumb and just can stop part scenery in your visual field observing the time exhibition arm of examining jobbie with one, but work as you rotate you head you can see that part of scenery that is blocked.Specifically, when you used Parallax to obtain depth perception information, brain was by calculating the relative distance of determining between you and two objects.
In brief, in the fusion process of binocular images, at first will rely on eyes at the same aggregation scheme (converging action) of observing scene, namely the point of fixation of eyes is on same point.This mechanism makes people's right and left eyes (people's left and right sides pupil is apart from fixing) and the point of fixation on scenery constitute a definite triangle at how much.Just can judge observed scenery apart from the distance of human eye by this triangle.For realizing this mechanism, human eye muscle need draw eyeball and rotate, and the activity of muscle feeds back to human brain again, and the anaglyph that eyes are obtained merges in human brain.
All eyes do not have organic disease, correcting defects of vision is lower than 0.9 and is called amblyopia (amblyopia).Amblyopia is the common eye diseases in children of clinical ophthalmology, it is infant period, owing to reasons such as a variety of causes such as consciousness, motion, conduction and the visual center are failed the stimulation of looking accepting to suit, the state that the visual performance that visual development is affected and takes place goes down mainly shows as visual disturbance and binocular single vision dysfunction.It is simple eye that amblyopia mostly is, but also eyes.Be categorized as according to the cause of disease: (1) strabismic amblyopia (Strabismic amblyopia); (2) ametropic amblyopia (Refractive amblyopia); (3) anisometropic amblyopia (Anisometropic amblyopia); (4) form deprivation amblyopia (Deprivation and occlusion amblyopia); (5) congenital amblyopia (Congenital amblyopia).
In Chinese children, the amblyopia sickness rate [can be referring to Bremner MH.Visual acuity in the primary school child aged four to twelve years:a review of amblyopia treatment in this age group at Princess Margaret Hospital.Aust J Ophthalmol1984 between 0.2% to 5.3%; 12:395 – 9. and Cole RB.The problem of unilateral amblyopia:a preliminary study of10,000National Health patients.Br Med J1959; 1:202-6].It is that 0.92%[can be referring to Zhao J that stream is in recent years readjusted the distribution existing amblyopia sickness rate in Beijing Shunyi District 5-15 child in year, Pan X, Sui R, et al.Refractive Error Study in Children:results from Shunyi District, China.Am J Ophthalmol2000; 129:427 – 35.]; Sickness rate Guangzhou same age bracket child is that 0.87%[can be referring to He M, Zeng J, Liu Y, et al.Refractive error and visual impairment in urban children in southern China.Invest Ophthalmol Vis Sci2004; 45:793 – 9.].Sickness rate in Qinghai-Tibet 6-14 year child is that 1.02%[can be referring to Lu P, Chen X, Zhang W, et al.Prevalence of ocular disease in Tibetan primary school children.Can J Ophthalmol2008; 43:95 – 9.].The key of amblyopia treatment is early discovery, early treatment.Yet the amblyopia sickness rate is not much accounted of for many years in the adult, in transferring 6830 crowds' more than 30 years old stream, the Hebei Handan District finds that the amblyopia sickness rate is 2.8% recently, its median ocellus amblyopia is 1.7%, the eyes amblyopia is that 1.1%[can be referring to Wang Y, Liang YB, Sun LP, Duan XR, Yuan RZ, Wong TY, Yi P, Friedman DS, Wang NL, Wang JJ.Prevalence and causes of amblyopia in a rural adult population of Chinese the Handan Eye Study.Ophthalmology.2011; 118:279-83.].Also have among the adult crowd abroad similar discovery [can be referring to McKee SP, Levi DM, Movshon JA.The pattern of visual deficits in amblyopia.J Vis.2003; 3:380-405.].Therefore, the diagnosis of amblyopia and treatment will certainly be subjected to hospital and patient crowd more and more pays close attention among the adult.
Clinical manifestation:
1. visual deterioration, distant vision is lower than 0.9 behind the correction of refractive errors.Correct defects of vision and be less than or equal to 0.1 for moderate and severe degree of amblyopia, vision 0.2-0.5 person is the moderate amblyopia, and vision 0.6-0.8 person is slight amblyopia.
2. poor to the more single sighting target of resolving power of the sighting target that is arranged in rows.
3. ametropia is arranged more; 4. often with stravismus and unusual solid looking; 5. nystagmus can be arranged.
Diagnosis basis:
1. correct distant vision and be lower than 0.9.
2. check the organic disease of not finding eye.
The Therapeutic Principle:
1. correction of refractive errors.
2. the person of central fixation: occlusion therapy, look irritation therapy, penalization treatment, improve vision.
3. paracentral fixation person: after image therapy, Red lightscreening plate or red flare therapy, Hai Dingge (Haidinger) brush, recover central fovea of macula and watch attentively.
4. synoptophore training.

The amblyopia instrument:
The amblyopia therapeutic equipment criteria for classification: domestic amblyopia therapeutic equipment has kind more than 50, divides by action principle and has only four big classes:
1, colour code class amblyopia therapeutic equipment (namely increase poor or weak eyesight indirectly and look instrument) is as light brush, red sudden strain of a muscle, after image, vision physiological, RGB coloured light, and coloured light such as pursues at special coloured light.Vision optimization system effect characteristics: can wake the visual cell of " sleep " (inhibition) up and increase and look
2, icon class amblyopia therapeutic equipment (namely directly increase poor or weak eyesight and look instrument) as the grade vision, trace designs, thread a needle, jack, flying spot sighting target, bifocal sighting target etc.Effect characteristics: can temper hypogenetic vision and increase and look
3, comprehensive amblyopia therapeutic equipment: have icon and coloured light concurrently and increase the multi-functional amblyopia instrument of looking.Effect characteristics: the effect with the complementary potentiation of colour code and icon function.
4, complex class amblyopia therapeutic equipment: by comprehensive+strengthen increase look+myopia prevention+the visual memory function is compound to be formed, and is present state-of-the-art amblyopia instrument.It is the sign of modern amblyopia instrument.Effect characteristics: have all functions of traditional comprehensive amblyopia instrument, other has increased to strengthen to increase and has looked (mobile icon, mobile colour code, bifocal flying spot sighting target etc.), myopia prevention (far changing mirror, focusing sensitivity device, bifocal sighting target etc.) and visual memory function (iconic memory, digital coding visual memory etc.).Can significantly shorten treatment time, improve curative effect, prevent the myopia that long-term amblyopia treatment causes, visual memory can increase the enjoyment of training and strengthen the anti-recurrence of visual perception memory.
But above-mentioned treatment means merits attention in the effect aspect the recovery visual performance.For example, in some one-sided amblyopia, only do correction of refractive errors treatment and seem existing therapeutic effect.The amblyopia employing that continues is blocked therapy and be can further improve vision.Although significant progress has been arranged aspect amblyopia treatment machine-processed understanding, yet still can't propose pointed therapeutic scheme with regard to the amblyopia symptom at present.
Specifically, still can't determine treatment dynamics and the therapeutic effect of the method for blocking at present.In addition, in correcting one-sided ametropia amblyopia process, as if if use partial occlusion and optical correction simultaneously, these two kinds of methods have same curative effect.Therefore, still need further research treatment list, the therapeutic scheme of eyes ametropia type amblyopia is [as Taylor K, Powell C, Hatt SR, Stewart C.Interventions for unilateral and bilateral refractive amblyopia.Cochrane Database Syst Rev.2012Apr18; 4:CD005137.].It is present main flow therapeutic modality that means treatment amblyopia is blocked in employing.Depend on and how to define healing [can be with reference to Stewart CE, Moseley MJ, Fielder AR.Defining and measuring treatment outcome in unilateral amblyopia.Br J Ophthalmol.2003; 87:1229-31.], external report shows that cure rate [can be with reference to Pediatric Eye Disease Investigator Group.A randomized trial of atropinevs.patching for treatment of moderate amblyopia in children.Arch Ophthalmol.2002 between 60-80%; 120:268-78. and Loudon SE, Polling JR, Simonsz HJ.Electronically measured compliance with occlusion therapy for amblyopia is related to visual acuity increase.Graefes Arch Clin Exp Ophthalmol.2003; 241:176-80. and Stewart CE, Fielder AR, Stephens DA, Moseley MJ.Treatment of unilateral amblyopia:Factors influencing visual outcome.Invest Ophthalmol Vis Sci.2005; 46:3152-60.], but the cooperate degree that depends on the patient [can be with reference to Loudon SE, Polling JR, Simonsz HJ.Electronically measured compliance with occlusion therapy for amblyopia is related to visual acuity increase.Graefes Arch Clin Exp Ophthalmol.2003; 241:176-80.].And amblyopia still can recur after blocking treatment.There are some researches show below 10 years old employing block the therapy for treating amblyopia or 1 year in reduce or the child that stops to treat in find that the amblyopia relapse rate is to have among 27%(653 the patient 179 to recur) [Data Source Bhola R, Keech RV, Kutschke P, et al.Recurrence of amblyopia after occlusion therapy.Ophthalmology.2006; 113:2097-100.].Therefore, be necessary to seek the Therapeutic Method that blocks beyond the therapy.
