This study evaluates the surgical outcomes of inverted internal limiting membrane insertion combined with air tamponade in the treatment of macular hole retinal detachment (MHRD) in high myopia, and also to compare the treatment efficacy and safety between different surgical approaches of MHRD
This study will evaluate the efficacy and safety of posterior scleral reinforcement on controlling myopia progression, including change in refraction, axial elongation as well as sight-threatening complications, in adults with high myopia. Half the adults will receive posterior scleral reinforcement, while the other half will receive no surgerical treatment.
To investigate the effect of caffeine on ocular circulation by using Optical Coherence Tomography and Optical Coherence Tomography Angiography. This study will evaluate blood supply to the inner and outer retina after consumption of 200mg caffeine capsule, in particular its effect in high myopes.
the investigator will evaluate the change in endothelial cell count in eyes implanted with the iris-claw phakic Artisan lens for treatment of moderate to high myopia using specular microscopy
To compare the outcomes of a toric Implantable Collamer Lens (ICL) and a spherical Implantable Collamer Lens combined with astigmatic keratotomy (AK) in the correction of high myopic astigmatism.
From July 2015 to December 2015, clinical record of 8 consecutive cases of macular hole with retinal detachment in high myopia treated with combined inverted and free ILM flap insertion into the hole were retrospectively reviewed. The anatomical and function outcomes were assessed.
The purpose of this study is to evaluate the long-term visual outcome of the cataract surgery using a large-scale and comprehensive database of high myopic cataract and age-related cataract patients. The investigators will further investigate into the various genetic and environmental factors that may contribute to the pathogenesis of high myopic cataract.
Macular schisis associated with macular detachment is a one of the complications of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling + gas injection versus vitrectomy + internal limiting membrane peeling + gas tamponade in a cohort of highly myopic eyes with macular retinal detachment associated with macular schisis.
Vitamin D deficiency is known to be significantly associated with high myopia. This study investigated the vitamin D status in patients with high myopia and primary open-angle glaucoma, in order to understand the relationship between high myopia and the development of primary open-angle glaucoma.110 primary open-angle glaucoma patients, 110 high myopia patients and 110 age-matched people in the Han population were enrolled. Serum levels of 1a, 25-Dihydroxyvitamin D3 were measured by an enzyme-linked immuno-absorbent assay.Vitamin D receptor polymorphic analysis was studied by polymerase chain reaction-restriction fragment length polymorphism technique.
