A visual acuity of 4.7 in a 5-year-old child is the lower limit of the visual acuity reference value for this age group. It is recommended to go to the ophthalmology department of the hospital for visual acuity examination, eye position examination, optometry examination, slit lamp examination, intraocular pressure and fundus examination, etc. to clarify the presence of refractive error, strabismus, amblyopia or other eye diseases. We recommend that you go to the ophthalmology department of the hospital for visual acuity examination, eye position examination, optometry examination, slit lamp examination, intraocular pressure and fundus examination, etc., so as to ascertain whether there is refractive error, strabismus, amblyopia, or other ocular diseases, and then treat the symptoms according to the causes.
1. Visual acuity examination: Visual acuity examination is the first step to detect visual abnormalities, which can quickly differentiate them from normal people. 4.7 is the lower limit of normal visual acuity for children aged 3-5 years old, and visual abnormalities should be suspected if the naked-eye visual acuity is lower than 4.7. 2.
2. Eye position examination: whether there is any strabismus, if there is strabismus, it is usually treated by glasses or surgery.
3. Optometry examination: Usually, atropine is needed to dilate the pupils slowly, and after dilating the pupils, we will get a real refractive state, such as myopia, hyperopia, astigmatism, or amblyopia, etc., which will be corrected by wearing glasses.
4. Slit lamp examination: check the cornea, anterior chamber, pupil size, lens, etc. to rule out vision loss caused by anterior segment diseases.
5. Intraocular pressure examination: check whether the intraocular pressure is in the normal range to exclude high intraocular pressure or glaucoma.
6. Fundus examination: Routinely check the fundus of the eye for the presence of fundus lesions.
This condition should be examined first, and then according to the results of the examination, targeted treatment should be done.
