Title: A Randomised, Double-Masked Study to Compare The Safety and Efficacy of Bilateral 0.5%, 0.1% & 0.01% Atropine Treatment In Controlling Progression of Myopia In Children
Brief Summary: The purpose of this study is to find an optimal dose of atropine for preventing the rapid progression of myopia in children by comparing the efficacy, safety and functional impact of binocular treatment with 0.5%, 0.1% and 0.01% atropine and to develop a treatment regimen for the routine management of childhood myopia.


Options:
A: Myopic volunteers, ages 20 to 35, who had not worn contact lenses were eligible to participate in the study if they were free of ocular disease, were in good physical health, and were not taking systemic medications that could have ocular side effects. In addition, eligibility was limited to persons with corneal curvature between 40.50 and 47.00 D (flatter keratometry reading), corrected visual acuity of 6/6 (20/20) or better in each eye, astigmatism less than 0.75 D, anisometropia less than 1 D, and myopia between 1 and 4 D.
B: Inclusion Criteria:

* Myopia between -0.50 and -6.00
* Eso fixation disparity at 33cm with distance correction
* Astigmatism 1.00 or less
* Ability to wear soft contact lenses

Exclusion Criteria:

* Presence of ocular disease preventing wear of contacts
* Pregnancy or nursing
* Use of certain medications
C: Inclusion Criteria:

* Grade of 1 to 5 in elementary schools and grade of 7 to 8 in secondary schools.

Exclusion Criteria:

* Visual defect or other eye diseases; wearing orthokeratology; refractive surgery history.
D: Inclusion Criteria:

1. Written Informed Consent from parent and assent from child has been obtained
2. Children aged 6 to 12 years
3. Refractive error of spherical equivalent -2.00 D or worse in each eye as measured by cycloplegic autorefraction
4. Active myopia progression of at least spherical equivalent -0.50 D over the last 12 months as determined or suggested by refractive records or change in lens power
5. Astigmatism of less than or equal to -1.50 D as measured by cycloplegic or non-cycloplegic autorefraction
6. Distance vision correctable to logMAR 0.2 or better in both eyes
7. A difference between non-cycloplegic subjective spherical refraction and cycloplegic subjective spherical refraction of not greater than -1.00 D
8. Normal intraocular pressure of not greater than 21 mmHg
9. Normal ocular health other than myopia
10. In good general health with no history of cardiac or significant respiratory diseases
11. No asthma-requiring medications in the past one year
12. No allergy to atropine, cyclopentolate, proparacaine and benzalkonium chloride
13. Willing and able to comply with scheduled visits and other study procedures

Exclusion Criteria:

1. Ocular or systemic diseases which may affect vision or refractive error
2. Any ocular condition wherein topical atropine is contraindicated
3. Defective binocular function or stereopsis
4. Amblyopia or manifest strabismus including intermittent tropia
5. Previous or current use of atropine or pirenzepine
6. Any other conditions precluding adherence to the protocol including unwillingness to refrain from contact lens wear for the duration of the study
