NCT ID: NCT03394300 Not yet recruiting - High Myopia Clinical Trials

Accuracy of Intraocular Lens Power in High Myopia

Start date: February 1, 2018
Phase: N/A
Study type: Observational [Patient Registry]

evaluation of the accuracy of iol power in high myopia using different biometry formula & iol master

NCT ID: NCT03383731 Recruiting - Retinal Detachment Clinical Trials

A Study of a New Surgical Treatment of Macular Hole Retinal Detachment in High Myopia

Start date: April 7, 2017
Phase: N/A
Study type: Interventional

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

NCT ID: NCT03381079 Not yet recruiting - High Myopia Clinical Trials

Efficacy and Safety of Posterior Scleral Reinforcement on Controlling Myopia in Adults With High Myopia

Start date: April 1, 2018
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT03294967 Completed - High Myopia Clinical Trials

Effect of Caffeine on Ocular Circulation in High Myopes

Start date: September 1, 2017
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03266354 Completed - High Myopia Clinical Trials

Changes of the Corneal Endothelial Cell Count After Artisan Phakic Intraocular Lens Implantation

Start date: October 1, 2017
Phase:
Study type: Observational

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

NCT ID: NCT03202485 Completed - Astigmatism Clinical Trials

Comparison Between TICL and ICL+AK for High Myopic Astigmatism

Start date: March 3, 2014
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03174639 Completed - Retinal Detachment Clinical Trials

High Myopia Macular Hole and Retinal Detachment Treated With Double ILM Flaps

Start date: March 11, 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03062085 Recruiting - Cataract Clinical Trials

Shanghai High Myopia Study

Start date: January 1, 2015
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT03023800 Completed - High Myopia Clinical Trials

Effects of Macular Buckle Versus Vitrectomy on Macular Schisis and Macular Detachment in Highly Myopic Eyes

Start date: April 2015
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03021629 Completed - Clinical trials for Vitamin D Deficiency

Comparison of Vitamin D Status and Vitamin D Receptor Polymorphisms in Patients With High Myopia and Primary Open-angle Glaucoma

Start date: July 2013
Phase: N/A
Study type: Observational

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.
