Description
Technical field
The present invention relates to a kind of suitable domestic by optical brush guided localized portable amblyopia therapeutic equipment, be mainly used in the various children's's amblyopias of family and TC, especially watching attentively property of wide-angle off-centre amblyopia.
Background technology
Be used for the treatment that off-centre watches attentively at present and mainly comprise amblyopia training and Drug therapy, the Drug therapy that China is commonly used like Si Liba, belongs to the Dopaminergics medicine.Bibliographical information is arranged, the improvement that helps off-centre to watch attentively.But it is even more important that training method seems, mainly contains Haidinger brush and various after image mirror.In the 50-70 age, similar ophthalmoscopic after image mirror commonly used clinically belongs to objective therapy, and light source is strong, and there is circular opaque disk in central authorities, and patient needs mydriasis during treatment, will hide the recessed irradiation of circle centring by the doctor and form after image.The shortcoming of this method is to need too much manpower, and needs mydriasis at every turn, therefore at present domestic seldom use.Home-made another kind of after image mirror, about 30 seconds of the light source prolonged exposure patient of use central zone black speck transfers passage of scintillation light then automatically to; Strengthen the after image function, belong to subjective method, its shortcoming is that the black speck diameter is big; When the patient watches black speck attentively; In fact remain off-centre and watch attentively, for low-angle off-centre, can cause central fovea and eccentric point of fixation to be hidden simultaneously and cause invalid.Eccentric for wide-angle, when the patient watches black speck attentively, protected eccentric point of fixation, but exposed the central fovea that needs protection originally, its consequence is that this treatment has all the more been consolidated off-centre and watched attentively.The applicant applied on the 20th in December in 2004 that name was called the patent of invention of " optical brush guided localized type after-image amblyopia therapeutic equipment " for this reason.A kind of optical brush guided localized type after-image amblyopia therapeutic equipment is disclosed in this patent; Comprise intense flash source and roundlet opaque disk; It is characterized in that: said therapeutic instrument also is provided with the light brush board of observing lens, half-reflecting half mirror and light brush and being provided with sighting target; Said smooth brush board plane with observe the vertical and light brush board sighting target of lens axis and be on the focus of observing lens, light brush board central point is dropped on the optical axis of observing lens, said half-reflecting half mirror is arranged between observation lens and the light brush board; Said intense flash source is arranged on a side of observing lens axis; The roundlet opaque disk vertically places on the optical axis in intense flash source, and constitutes about the half-reflecting half mirror conjugation with sighting target, and said lens axis and intense flash source optical axis are in same plane.
This therapeutic instrument adopts Haidinger brush and the symphyogenetic principle of after image mirror, produces central fixation by the Haidinger brush guiding, and Haidinger brush is looked like to transfer to the central authorities of light brush board; Roundlet opaque disk central point and patient's central fovea of retina conjugation, through letting the patient observe Haidinger brush, the direction center is recessed to be watched attentively; Roundlet opaque disk protection central fovea; Intense light source bleaching off-centre is watched position and other retinas attentively, watches attentively thereby suppress off-centre, improves foveal vision.But because existing therapeutic instrument uses large-scale light brush, and flash lamp independently, volume is bigger, and brake sack is designed to free module, need take out during use, and comparatively trouble use the light of improvement to brush localized after image method treatment simultaneously only, and cost of manufacture is higher; On the other hand,, carry inconvenience, be not suitable for domestic because volume is bigger; Make the patient must arrive hospital at every turn and treat, and the treatment of amblyopia is to need a suitable time course, need be through treatment repeatedly; If not according to the treatment of carrying out enough number of times the course of treatment, then curative effect does not reach again, cause very large inconvenience for patient's treatment; Especially not local patient for those, even also will stay, increased medical treatment cost and burden.
Summary of the invention
