Description
Technical field
The present invention relates to a kind of heterophoria (phoria) inspection method and system, whether have heterophoria to judge the examinate quickly and accurately.
Background technology
The mankind have eyes, and when watching extraneous scenery, each eyes can both form an independent image, and because eyes have possessed the ability of melting picture (fusion), make human eyes be seen single image.In simple terms, human eyes through the loaded down with trivial details translation mechanisms of brain, permeate each simple eye message that obtains after the extraneous image of indivedual receptions.
The mankind have two of direct-view forward and are positioned at the place ahead of head, and therefore two the optical axis is almost parallel, and in melting the picture process, two palpuses possess the eye position that aligns sighting target, brain can easily be reached melt the camera energy.After melting picture and removing, eyes are all melts camera system and all is in and stops, and for example: cover eyes, make two eye shadow picture differences, this moment, the eye position was only decided by anatomical and physiological factor.Under a few cases, separate eye position and all spokes system that gathers all be under the running to melt the picture eye identical, i.e. normotopia (orthophoria).And under most of situation, separating the eye position and melt picture eye position can be different, be that what is called departs from (deviation), this because two eye shadow pictures separate and departing from of causing is so-called heterophoria or loxosis (phoria), and heterophoria only all melt camera system all be in stop the following eyes that produce biased from.In addition, if two eye shadow pictures all are under the running in all camera systems of melting, and there are two situations about departing to take place, this meaning stravismus (heterotropia).
Heterophoria be a kind of potentiality eye biased from, but can keep two normotopias and not show and depart from melting under the camera system, once the brain fusion is blocked, eye is biased from promptly manifesting.Divide from the trend direction according to eye is biased, exophoria (exophoria) is arranged, esophoria (esophoria), hyperphoria (hyperphoria), inward turning heterophoria (incylophoria) and outward turning heterophoria (excyclphoria).And in order to reach two single looking, then must use to melt to open diffusing power (fusional divergence reserve) or melt and gather power mechanism such as (fusional convergence reserve) as the property spoke and melted picture and remove eye position (a fusion-free position), so cause symptoms such as eyestrain, diplopia or headache easily as property.
According to prior art, heterophoria can use prism to be corrected, and can alleviate like this to melt to open the power of loosing as property and gather the burden that power caused with melting as the property spoke, reaches the symptom of removing eyestrain, diplopia or headache.And the heterophoria person is under two situations that can see same sighting target, can't measure under getting involved because of melting camera, only destroys and just can show melting picture.According to existing inspection stravismus or heterophoric instrument or inspection technique, checking process loaded down with trivial details tediously long and need meticulous and highly skilled operator just can obtain accurate result (as stravismus amount, heterophoria amount, maximum melt as property open diffusing power, maximum melt as the property spoke gather power and other relevant physiological information).The gained result also needs to utilize some prism rules to carry out computing (as Sheard ' s criterion, Percival ' s criterion or other rule), could obtain the prism amount of required adding.If in this process, a link has deviation slightly, and then the gained the possibility of result runs counter to desire.Further specify, the modal method of prior art is prism partition method, polariscope partition method and red green optical filter partition method and corresponding sighting target separately, make two branches although measure its bias under the situation of sighting target separately, measure in the mode of prism compensation then.
The shortcoming of prism partition method maximum is do not have the periphery to melt picture under the enforcement state, neither under free space, implement and eyes in daily life environment dissmilarity, so the bias of measuring is higher.And the shortcoming of polariscope partition method and red green optical filter partition method is: (1) has only very little by about 1.5.The visible apparent coordinates admittedly of center eyes, have only a small amount of or even do not have periphery to melt picture; (2) use the mode of two straight lines or horizontal line alignment to measure, lead to errors because of the drift of lines sighting target easily; (3) polariscope causes the sighting target released state to lose efficacy when head inclination easily, makes and has only the visible sighting target of a glance originally, all can see for two.
Therefore, the object of the present invention is to provide a kind of heterophoria examination method and system, and then address the above problem.
