After timely fitting of glasses, persistent masking of one eye, amblyopia training and other comprehensive treatments, the child’s corrected visual acuity improved significantly, and the treatment of amblyopia achieved stage-by-stage success. This shows that early detection, early diagnosis and early treatment are very important in the treatment of amblyopia. Basic information] Male, 5 years old [Disease type] Amblyopia (refractive error, left eye) [Hospital] The First Affiliated Hospital of Zhengzhou University [Time of consultation] October 2021 [Treatment plan] Ciliary muscle paralysis optometry + prescription glasses + cover the right eye + amblyopia training [Treatment cycle] 6 months, monthly outpatient follow up [Effect of treatment] Corrected visual acuity in the left eye has improved significantly A. Initial consultation 5-year-old boy never responded that he could not see clearly. The 5-year-old boy never reacted that he could not see clearly, and his parents did not find that the child had difficulty in seeing things, and his kindergarten physical examination report said that his vision did not meet the standard. After communicating with the child, I learned that the original children have long known that their left eye vision is poor, but never felt abnormal, and did not inform their parents. The parents responded that the child could usually see very small things and had not intentionally checked his monocular vision. Therefore, the first thing we did was to look for the cause of the poor vision in one eye. Through the examination, we found that: no obvious abnormality was found in the external eyes of both eyes; bilateral pupils were sensitive to light reflex; Va: OD0.8, OS0.25; Simultaneous machine: I 0°, Ⅱ no, Ⅲ no; Titmus stereoscopic vision: no; Worth4 spotlight: near 4, far 2; Compound tropicamide dilated pupil optometry: OD+1.50DS/+1.00DC×10=1.0, OS+3.75 DS/+1.25DC×5=0.3; funduscopic examination: normal. Preliminary diagnosis: amblyopia (refractive parametrization, left); refractive error (double) II. Treatment After the initial diagnosis, considering that the 5-year-old child had strong adjustment, in order to more accurately check the optometry, after obtaining the consent of the child and his family, he was given atropine ophthalmic gel, and the patient was advised to go home to spot the eyes, and was instructed to use it in strict compliance with the doctor’s instructions, and then to be rechecked in outpatient clinic after 5 days. After 5 days, review optometry: OD+2.00DS/+0.75DC×10=1.0, OS+5.50DS/+1.50DC×7=0.3. Lens prescription: OD+1.00DS/+0.75DC×10, OS+4.00DS/+1.50DC×7; asked to cover the right eye for 5 days and let go of the right eye for 1 day; and to review the eye after 1 month. The patient was not reviewed at the requested time and was reviewed 2 months later. va cc: OD 1.0, OS 0.3+; eye position: positive. Follow-up treatment, parents responded that the child was basically able to wear lenses all day long, but was reluctant to cover his right eye and there were cases of peeking. Therefore, the treatment plan was adjusted: insist on wearing lenses; after school every day, cover the right eye for 4-6 hours under parental supervision; combined with amblyopia training of the left eye for 30 minutes every day; and review in 2 months. The patient was rechecked 2 months later, and the parents reported that the child cooperated with the treatment and basically did not peek. va cc:OD 1.0, OS 0.5; eye position: positive. Synoptic: I 0°, II +20~-3, III none; Titmus stereopsis: 400″; Worth4 spotlight: near 4, far 2. Examination result suggests:Visual acuity is improved, treatment is effective, but binocular vision function is poor. Recommendation: Same treatment as before, increase binocular vision training, and review in 2 months. After re-examination, it was recommended to replace the glasses, prescription: OD +0.50DS/+1.00DC×10, OS +3.00DS/+1.50DC×5; binocular vision training and amblyopia training was changed to twice a week; re-examination after 3 months. Third, the treatment effect After adjusting the treatment plan, the review found that Va cc: OD1.0, OS0.8-; eye position: positive; synoptic machine: I 0°, II +25~-5, III present; Titmus stereopsis: 100″; Worth4 spotlight: near 4, far 4; Compound tropicamide dilated pupil optometry: OD+1.50DS/+1.00DC×10=1.0. OS+3.75DS/+1.25DC×5=0.8. The examination results suggested that the corrected visual acuity improved significantly and the visual function of both eyes was restored better. Through the active cooperation and standardized treatment of the patient and his family in the past 6 months, the patient’s vision in the left eye has been significantly improved and effectively enhanced, which shows that the treatment effect is remarkable. Precautions The corrected visual acuity of the left eye of the patient was significantly improved after treatment, which was very happy for the patient. However, patients should pay attention to the following matters: 1, patients should avoid visual fatigue, rest their eyes appropriately, and pay attention to eye hygiene. 2, diet can eat more good for the eyes. 2, diet can eat more good for eyesight food, such as carrots, blueberries, as well as fresh vegetables and fruits, etc. also need to be supplemented. 3.Covering therapy is classically effective, parents should pay attention to timely communication with the patient to understand whether there is any difficulty in covering, and adjust the covering program in time to avoid the emergence of medical amblyopia. 4, patients in the treatment of amblyopia at the same time, should also pay attention to the establishment of binocular vision. Amblyopia training and binocular vision training are good treatment aids. V. Personal perception The child patient cannot take the initiative to generate the need for consultation because he or she cannot accurately and subjectively express or understand the abnormal visual experience. If parents do not pay special attention to their children’s eye health, the diagnosis and treatment of amblyopia may be delayed. Therefore, health checkups in educational institutions are particularly important in the prevention of amblyopia, and it is generally recommended that eye checkups should be conducted at the time of admission to school. Ciliary muscle paralysis optometry is a scientific means to accurately understand the refractive state of children, and pupil-dilating drugs are metabolized without obvious toxic side effects. Parents must be aware of this, not to believe the rumors, do not reject the dilated pupil examination. Amblyopia treatment is a long-term, gradual process, treatment throughout the child’s daily life, most of the effects of treatment in the 3-6 months, the entire treatment time generally extends for 2-3 years. Parents should fully communicate with their children, believe in science, trust the doctor, and work together to restore vision.
