Overview
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
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.
Eligibility
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
