Due to the characteristics of children’s age and the existence of various eye diseases that require treatment, the principles of prescription for children and adults are completely different, and the principles of prescription for children’s myopia and amblyopia are also very special. In order to standardize the dispensing of children’s glasses in our hospital, so that we can have a unified dispensing rule to follow, we integrated the rules of children’s dispensing in other hospitals in China and developed the following principles for your reference.
I. Principles of dilated pupils for children.
1. Children under 8 years of age: All atropine dilated pupils for optometry
(1) Children without strabismus and children with exotropia should have their pupils dilated with atropine for three days.
(2) Children with combined internal strabismus should have their pupils dilated with atropine for five days (to remove the adjustment factor).
(3) Children with amblyopia, able to wear glasses regularly and have their doctor decide whether they can use Midori dilated pupils before changing glasses (adjustment relaxation)
2.Children over 8 years old.
(1) Children with complaints of poor visual acuity at the first consultation, Midori or Toppingamide dilated pupil optometry.
(2) For those whose vision cannot be corrected after pupil dilatation, they should be referred to the amblyopia and strabismus clinic for medical consultation.
(3) Children with combined amblyopia should have their pupils dilated with atropine.
(4) After optometry, if it is simple myopia, the optometry office can directly retest and prescribe glasses.
(5) The optometry office can ask the doctor to consult the prescription plan for some special prescription children (children with high myopia, large astigmatism, progressive myopia).
(6) need to ask the doctor consultation of children by the optometry room directly plus professional number (unlimited)
II. Children’s prescription principles.
1, not combined with strabismic amblyopia (not combined amblyopia)
(1) Myopia is the minimum correction of the best vision, vision correction to 1.0 can be
(2) Farsightedness minus adjustment prescription, by the optometrist trial and according to visual acuity and symptoms prescription (farsightedness minus 1D adjustment)
(3) For children who do not cooperate with the examination of myopia regular prescription, farsightedness and then subtract 1D adjustment prescription.
2. Dispensing for children with amblyopia (not combined with strabismus)
(1) Children under 6 years old, with adequate correction of hyperopia and astigmatism (low age children have strong visual adaptation ability).
(2) Children between 6 and 9 years old, high hyperopia should be reduced, astigmatism should be corrected in sufficient amount, and the second prescription should be adequate for hyperopia.
(3) Children over 9 years old, high hyperopia and high astigmatism should be corrected in accordance with 2/3 of the first prescription, and the second prescription should be given in full (poor adaptation ability of older children)
Children with refractive error, and younger children can be given glasses in excess of the normal amount (more than 300 degrees in both eyes). Older children should be given glasses according to medical advice.
3, amblyopic children with glasses (combined with strabismus).
If amblyopia combined with strabismus needs to be treated, glasses will be dispensed according to the principles of amblyopia dispensing without considering strabismus, and then according to the principles of strabismus and surgical dispensing after amblyopia is cured.
4, strabismic children with glasses (not combined with amblyopia)
(1) Exotropia, exotropia
A. Combined with hyperopia, low correction with glasses (hyperopia is large, can aggravate exotropia)
B, combined with myopia, adequate correction, (myopia can control exotropia)
(2) internal strabismus, internal oblique
A, combined with hyperopia, adequate correction (hyperopia can control the internal strabismus)
B, combined with myopia, appropriate low correction (the best vision, the minimum number of degrees)
C. Adjustment of internal strabismus, full correction of farsightedness with lenses, change of lenses should be based on the results of the same vision machine to reduce the farsightedness, should ensure that the strabismus does not increase the premise of reducing the number of farsightedness.
Third, the optometry program for young children.
Some young children need optometry, but the children do not cooperate, and when they grow up, they miss the best time for treatment. We have developed a new program of oral chloral hydrate optometry for these children, and these children can complete the examination of silhouette optometry under the guidance of doctors, and the development of this new program provides good conditions for the early treatment of these infants and children.
