Title: High Myopia - Partial Reduction Orthokeratology Study
Brief Summary: The purpose of this study is to evaluate and compare the eyeball elongation in high myopic children using partial correction orthokeratology and single-vision spectacles.


Options:
A: Inclusion Criteria:

* Myopia (refractive sphere): \> 5.75D
* Astigmatism: \< ½ of myopia; with-the-rule astigmatism (axes 180 +/- 30) ≤1.25D; astigmatism of other axes ≤ 0.50D
* Spherical equivalent (SE): \> 5.75D
* Anisometropia: ≤ 1.50D in both refractive sphere, refractive cylinder and SE
* Best corrected monocular visual acuity: equal to or better than 0.10 in logMAR scale in both eyes
* Willingness for randomization
* Availability for follow-up for at least 2 years

Exclusion Criteria:

* Strabismus at distance or near
* Contraindication for contact lens wear and orthokeratology (e.g. limbus to limbus corneal cylinder and dislocated corneal apex
* Systemic or ocular conditions which may affect contact lens wear (e.g. allergy and medication)
* Systemic or ocular conditions which may affect refractive development (e.g. Down syndrome, ptosis)
B: Inclusion Criteria:

* all included patients, age from 6 to 15 years, had myopia (spherical equivalent \> -0.5 D) after cycloplegic refraction,
* The astigmatism and anisometropia were less than 2.0 D,
* IOP was less than 21 mmHg.

Exclusion Criteria:

* the presence of related disease such as infection, ulceration, eyelid disease, ocular and auricular disorders,
* individuals with amblyopia or strabismus,
* individuals received any other therapies in the period of study,
* individuals suffering some sort of haemostasis disorder,
* individuals did not follow the treatment (eyedrops and/or stimulation of auricular acupoints) over seven days
C: Inclusion Criteria:

* Children aged from 6 to 12 years with myopia, defined as spherical equivalent (SE) of -0.5 diopter (D) or less, were recruited from the outpatient clinics from January 2011 to June 2012.

Exclusion Criteria:

* (1) abnormal IOP (\>21 mmHg) at presentation, (2) astigmatism or anisometropia of more than 1.5 D, (3) amblyopia or strabismus, (4) the presence of any related eyelid diseases, ocular diseases, or auricular diseases, (5) the presence of hemostatic disorders or other related major systemic diseases, (6) history of allergy to atropine, (7) previous or current use of contact lenses, bifocals, progressive lenses, or other forms of treatment for myopia.
D: Inclusion Criteria:

* Refractive error determined by cycloplegic autorefraction which meets all of the following:

  1. Spherical equivalent: -0.50 to -3.00 D in both eyes
  2. Astigmatism \<= 1.5 D in both eyes
  3. Anisometropia \<= 1.00 D difference between eyes in spherical equivalent
* Visual acuity is at least 20/20 with best subjective refraction in both eyes
* Accommodative response at near (33 cm) is less than 2.0D by non-cycloplegic autorefraction
* Near esophoria (\>= 2.0 PD) present by alternate prism and cover test (APCT) at near using best refractive correction determined from non-cycloplegic subjective refraction

Exclusion Criteria:

* Strabismus present by cover-uncover test at far, near, and/or near with +2.00D over best subjective refraction
* Current or prior use of PALs, bifocals, or contact lenses in either eye (prior or current use of SVLs is allowed)
