First affect the factors of myopia
1. Environmental factors: too early close work, less outdoor activities, bad reading and writing habits, over-eating eclipse, excessive intake of sweets, less sleep time, trace elements, excessive use of electronic products, lighting, etc. are all myopia High risk factor
2. Genetic factors: genetics, ethnicity, parental age and other factors.
Establish a preventive mechanism for early risk assessment of myopia
True myopia can be prevented from being incurable. Therefore, from the kindergarten period (3 to 4 years old), children should be regularly checked (3 to 6 months) for visual acuity, diopter, axial length, corneal curvature and fundus eye position. The light development archives help early detection of children with poor vision, myopia and nearsightedness, and manage and develop appropriate interventions. For children with genetic factors or family history of high myopia (high-risk myopia), regular follow-up should be strengthened to carry out key prevention and control.
Standard inspection process for myopia
1. Interview: history of medical history, family history, exposure to susceptible factors of myopia;
2. visual acuity examination; 3. slit lamp examination; 4. fundus examination; 5. adjustment and binocular visual function examination; 6. corneal curvature examination; Eye shaft length examination; 8. Ciliary muscle paralysis optometry; 9. Intraocular pressure examination; 10. Establish adolescent eye health development file.
Standardized optometry procedure
1. Dominant eye examination;
2. Objective optometry (computer optometry / retinoscopy optometry);
3. Comprehensive optometry: fog vision, initial MPMVA, red and green test, crossed cylindrical mirror precise astigmatism, again MPMVA, red-green test again, binocular vision balance;
4. Adjustment check: BCC, NRA, PRA;
5. Patients with strabismus, monocular amblyopia, and anisometropia should check for woth 4 hole lights and inconsistency.
