Description

The glasses for the treatment of stravismus

Technical field

The present invention relates to a kind of glasses for the treatment of stravismus.

Background technology

All eyes without organic disease, correcting defects of vision is called amblyopia lower than 0.9.Amblyopia is the common eye diseases in children of clinical ophthalmology, it is infant period, due to a variety of causes as the reasons such as consciousness, motion, conduction and the visual center fail to accept suitable to look stimulation, visual development is affected and the state that goes down of the visual performance occurred, main manifestations is visual disturbance and binocular vision obstacle.

Amblyopia is comparatively common eye diseases in children, and sickness rate is about 3%.Amblyopia occurs over just vision still immature infant period.Because being the fastest period of visual development in critical period (3 years old before) of visual development and sensitive period (6 ~ 8 years old), while be also the period that vision is suffering abnormal environment stimulation the most easily to produce permanent lesion.Therefore, within the critical period and sensitive period of visual development, timely correction of refractive errors, anisometropia, stravismus and removal visual deprivation factor are the basic ways that prevention amblyopia occurs.The consciousness that department of pediatrics and ophthalmologist should have great prevention amblyopia to occur, should notice whether observe infant has the possible factor producing amblyopia, and by feasible detection means early discovery, correct in time.

Amblyopia western medical treatment method suppresses by eliminating, and improve vision, corrective ophthalmic position, training macula lutea fixation and fusion function, to reach recovery two visual function.The therapeutic effect of amblyopia is relevant with age and fixation character, and 5 ~ 6 years old better, poor after 8 years old; Center fixation is better, and other center fixation is poor.

Usual employing covering method: covering method (occlusion) has a very long history.Along with the raising to the pathophysiology understanding of causing a disease, the process of disease also correspondingly improves.Think that the decline of amblyopia eye vision is the reason producing stravismus as far back as deBuffon in 1743, thus suggestion hides fixating eye.Much it is believed that amblyopia is a kind of congenital heredity sexual abnormality year later, thus abandon and even oppose occlusion therapy.Scholars recognized that amblyopia was a kind of functional exception afterwards, were to adapt to the aesthesia of stravismus, so recovered again occlusion therapy, until it still treats the main of amblyopia and most effective method at present.

Covering method has traditional covering method (lid dominant eye forces amblyopia eye fixation) and reversing covering method (lid paracentral fixation amblyopia eye, makes it to change central fixation into).Covering method also can be completeness or partial, and the former refers to full-time covering (can remove during sleep, but cover immediately after getting up), and the latter refers to that every day hides a few hours.Treatment developmental character amblyopia, from the beginning of time must whole day hide, later for maintaining the vision that consolidation obtains, part overlaid method can be implemented.Current scholars advocate to hide dominant eye, force amblyopia eye fixation.Covering method can remove the inhibitory action to amblyopia eye caused owing to stimulating fixating eye.

Scott report stravismus property and anisometropic amblyopia can obtain very satisfied result after whole day traditional covering therapy.Occlusion therapy is also effective to large age group (7 ~ 9 years old) child, but the course for the treatment of, less age group was long.The infant of 50% ~ 66% can maintain the vision obtained after treatment stops.

As can be seen from above-mentioned report, amblyopia directly or indirectly can cause stravismus, and closely related, and the hazardness of stravismus is more remarkable, can allow patient two can not fixation object simultaneously.Belong to extraocular muscles disease, concomitant strabismus and the large class of paralytic strabismus two can be divided into.Concomitant strabismus with eye biased to temporo side, eyeball WD, without diplopia for main clinical characteristics; Paralytic strabismus then has Limit of ocular movements, diplopia, and vertigo, feel sick, the General Symptoms such as instability of gait.Stravismus glasses join mirror method treatment stravismus, be first for amblyopia, to impel two good visual acuities, secondly for correcting the eye position of deflection.The Therapeutic Method of stravismus comprises: wear glasses, coverings of eyes fixing upward cover, eye orthoptic exercises, eye muscle perform the operation or the comprehensive use of said method.Eyes fixing upward cover is the amblyopia caused by treatment stravismus.Orthoptic is utilize instrument to strengthen ocular movement.Eye muscle is performed the operation one or more eye muscle then comprised in the extraocular muscles loosening or shorten at a glance or two.Slight stravismus can be worn " prism spectacles " to rescue.

But, because patient is in dominant eye and the asymmetric state of amblyopia eye fixation target for a long time, existing treatment means, except operation, hides dominant eye separately, force amblyopia eye fixation, or wear glasses, eye orthoptic exercises all cannot change the inclined head bad habit of stravismus that patient forms at ordinary times.Often again cause ocular disease because of inclined head fixation object because treatment terminates.

Therefore, be badly in need of providing a kind of and can correct the glasses that patient looks side ways the treatment stravismus of inclined head bad habit.

Summary of the invention

The object of this invention is to provide a kind of can correct patient look side ways inclined head bad habit treatment stravismus glasses.

Basic conception of the present invention is: by the discovery that studies for a long period of time, one of them key factor for the treatment of amblyopia and stravismus, is exactly the bad habit of correcting the inclined head of patient, allows eyes be in same parastate fixation object.In order to reach this object, the glasses for the treatment of stravismus of the present invention adopt the mode of restriction patient fixation range, make the fixation object of patient two be in same parastate.Once the inclined head of patient, the sidewall of the hollow mask on glasses will by target occlusion, and patient loses fixation object, head will inevitably be ajusted allow eyes again obtain target, thus repeated multiple timesly carries out the bad habit of correcting inclined head.Gradually the inclined head bad habit of patient is corrected.

Specifically, the glasses for the treatment of stravismus of the present invention, comprise spectacle frame, described spectacle frame has left eye picture frame and right eye picture frame, it is characterized in that described left eye picture frame and right eye picture frame are all installed with the hollow mask axially extending to and lack five centimetres and both ends open.That is, left eye picture frame and right eye picture frame are separately installed with the hollow mask being in same level state, the eyes of patient can be allowed to see away from two hollow masks respectively and watch same target attentively.The aperture of hollow mask can adjust according to patient's degree of looking side ways, and is reduced in aperture gradually according to stravismus improvement degree.In other words, hollow mask can be the hollow mask of adjustable aperture.

The cross section of hollow mask of the present invention can be annular or hollow polygon.Hollow polygon described here can be hollow square, hollow rectangular or hollow six rhombus etc.

Hollow mask of the present invention can be movably set with covering.So, just can hide dominant eye separately according to actual service condition, force amblyopia eye fixation to correct defects of vision; Or hide amblyopia eye separately, force dominant eye to watch attentively to recover vision.

The glasses for the treatment of stravismus of the present invention, can allow patient keep correct status fixation object for a long time, thus the inclined head stravismus bad habit that correction patient forms.By wearing for a long time, effectively can correct patient's stravismus and amblyopia, patient can't be allowed not feel well.Once the bad habit of head stravismus is repaired partially, patient compliance's other treatment means are recovered, and will break away from ocular disease no longer recurrent exerbation.

Compared with the aforementioned existing similar products, the glasses that treatment of the present invention is looked side ways can be corrected patient and look side ways inclined head bad habit.

Content of the present invention is further described with the following Examples, but content of the present invention is not limited only to content involved in embodiment.
