Myopia
Conditions
Brief summary
To explore the repeatability of AO-SLO (Mona IIa) technology and the difference of cone cell density between individuals who used or not used repeated low-intensity red light treatment
Detailed description
This study focuses on the population with long-term use of repetitive low-intensity myopia, exploring the safety of repetitive low-intensity red light over a long period of use, and providing data support and clinical guidance for the field of repetitive low-intensity red light. It investigates the repeatability of adaptive optics scanning laser ophthalmoscope technology and observes the safety of repetitive low-intensity red light treatment for children over a long period of use.

Inclusion criteria
* 6 - 55 years old, gender not limited; Obtained informed consent.
Exclusion criteria
* Children with obvious strabismus and amblyopia * With congenital eye disease, such as congenital cataract, congenital retinal disease * Secondary myopia (such as premature retinopathy or other eye diseases in infants and children caused secondary myopia), or myopia combined with systemic syndrome (such as Marfan syndrome) * Had internal eye surgery (such as cataract extraction, intraocular lens implantation, anti-glaucoma surgery, etc.) * Refractive medium opacity (such as corneal disease, crystal opacity, etc.) * Bnormal intraocular pressure and clinical significance (IOP \<10 mmHg or IOP\>21mmHg or binocular IOP difference ≥5mmHg) * Fundus chorioretinopathy (except for high myopia fundus degenerative changes) or other intraocular diseases * Optic nerve damage or congenital optic nerve dysfunction * Can not be regularly checked * The adjustment range is less than 8D or obvious near difficulties * Other reasons researchers think it is not suitable for inclusion in researchers
