Description

Amblyopia therapeutic equipment

(1) technical field

The present invention relates to a kind of medical device technology device for the treatment of ophthalmic diseasess such as children's myopia using.

(2) background technology

Amblyopia is the commonly encountered diseases in the childhood development process, it is generally acknowledged, amblyopia is grown unsound owing to macula retinae or the function inhibition causes.Amblyopia is a kind of growth irregularity ocular disease, and amblyopia is often by due to stravismus, anisometropia or the height ametropia.The hazardness of amblyopia not only is visual disturbance, sees that object is smudgy, also be to lack perfect stereopsis, and stereoscopic vision is the social essential highest visual performance that adapts to scientific and technological high speed development.

Amblyopia can be regarded a kind of vision " atrophy " or visual cell " sleep " in essence as, and the effect of amblyopia instrument is to wake the visual cell of " sleep " up and increase indirectly and look or temper the vision of " atrophy " and directly increase and look with icon with colour code.This shows that the amblyopia instrument increases view principle can reduce two big classes: 1, icon function is tempered the vision of " atrophy "; 2, the coloured light function " is waken " visual cell up.

The amblyopia treatment method of widespread usage is more at present, suppresses therapy and looks irritation therapy or the like as occlusion therapy, after image therapy, red filter treatment, medicine optics.

Wherein, occlusion therapy is still one of main method of treatment amblyopia at present.Occlusion therapy uses eyeshield to hide strong eye to eliminate the inhibitory action of amblyopia eye.Can take to hide strong eye half a day with interior child in 1 year old, and impel the amblyopia eye fixation, to avoid occlusion amblyopia, 2 years old child can adopt and hide rule at 1: 1; But 3-4 year child hides the time proper extension.Strong at the moment in check, should extract cover earlier 5 minutes, make strong adaptation of eye indoor light and surrounding enviroment.After treating that the amblyopia eye has obtained best vision, then full-time covering is changed into part-time and hide, continue to hide.When the amblyopia eye vision no longer continues to improve after 3 months, can stop covering method.The method is because old stuff too, and child mismatches, and the child who has worries to be ridiculed by the classmate and is reluctant the eyes fixing upward cover, and time gets when wearing, and affects the treatment.And occlusion therapy is a kind of passive therapy in essence, also may cause occlusion amblyopia.

The treatment principle of after image therapy is: show off the peripheral retina of center amblyopia with high light, comprise the paracentral fixation district, make it to produce and suppress; Block the protection macula lutea with the black disk simultaneously, make it not be subjected to showing off of high light, under indoor flash of light, train to improve the macula lutea function of amblyopia eye then.During treating, also should hide the amblyopia eye on ordinary days, prevent paracentral fixation.Few at present the use is because of this method is taken manpower, time-consuming, apparatus expensive.

Red filter treatment designs according to amphiblestroid anatomical physiology.Central fovea of macula only contains cone cell, is divided a word with a hyphen at the end of a line to periphery by central fovea, and cone cell sharply reduces, and rod cell increases gradually, and rod cell does not see under HONGGUANG spectrographic red terminal insensitive, and cone cell is then responsive, can see clearly under HONGGUANG.Hide strong eye on ordinary days, on amblyopia Correct-Eye-Scope sheet, add a red film (HONGGUANG that is shorter than 640 nanometers can not filter) that specification is arranged.Red film can impel the paracentral fixation eye spontaneously to change central fixation into.Degree of depth amblyopia patient is unsuitable for using this therapy, uses red film because add, and luminous ray reduces, and vision further descends, and causes the behavior difficulty, and it is noticeable to wear the red film picture frame in addition, and the utmost point is not attractive in appearance, and general being difficult for accepted by the patient.

It is to utilize to correct or owe to rectify eyeglass and every atropine to constrain the function of strong eye that medicine optics suppresses the therapy principle.The amblyopia eye is worn normal correcting lens and is seen far or wear the overcorrection eyeglass in order to seeing closely.Its advantage is to cover eye, can prevent occlusion amblyopia, and Dai Jinghou amblyopia eye vision can increase, and slant visibility can reduce or disappear, and also is suitable for the nystagmus of latency.The shortcoming of this therapy is only to be applicable to the moderate amblyopia, uses atropine also may cause new amblyopia at strong eye for a long time, therefore should be prudent at the long-term one-sided use atropine of the still immature infant of vision.In addition the course of treatment long, the expense height, curative effect is very limited.

The principle of looking irritation therapy is: animal and human's visual cell has good reaction to different spatial frequencys, and neuron can be done sensitive the adjustment to spatial vision.Utilize hard, the bar grid that spatial frequency is different stimulate the amblyopia eye to improve vision as stimulus.The bar grid can rotate, and make the visual cell of amblyopia can both accept the stimulation of different spatial frequency bar grid on each orientation.Need not cover eye on ordinary days, hide strong eye during treatment.The best indication of this therapy is the weak and ametropic amblyopia of central fixation's property, and total curative effect is not as good as occlusion therapy or composite treatment, paracentral fixation person weak effect.

Because above-mentioned the whole bag of tricks respectively has characteristics, mechanism is not quite similar, and curative effect is limited, and the normal employing 2 of domestic hospital or 3 kind of method are carried out Comprehensive Treatment, and its effect is obvious than monotherapy.The Drug therapy of amblyopia still is in the starting stage at home at present, and it is less to observe routine number, and the time of following up a case by regular visits to is short, problems such as relevant optimal dose, administration time, dosage form improvement, late result and treatment mechanism thereof, and the further research of still needing is explored.
