Active clinical trials for "Myopia, Degenerative"

Myopia is a global healthy concern, especially the high myopia and pathological myopia among Asian populations. However, its mechanism still remains largely unclear. Recent findings suggested choroidal changes might be related to the development of myopia. This study is to useOCT angiography (OCT-A) to investigate parapapillary choroidal microvasculature change in myopic eyes, and try to find the cause-and-effect relationship between choroidal change and the development of myopia.

The goal of this multi-center, randomized, parallel-controlled clinical trial is to evaluate the effectiveness of outdoor activities monitoring and motivating by smartwatches to prevent myopia progression in children. The main question it aims to answer are: To evaluate the two-year change of spherical equivalent progression. To evaluate the change in axial length, the incidence of myopia, the time of outdoor activity, the choroid thickness, and blood flow through the two-year intervention. Participants will wear smartwatches and receive Mini Program outdoor activity reminders and motivations. The required outdoor activity time is 2 hours from Monday to Friday and more than 2 hours on weekends. The control group will only wear smartwatches for monitoring. Researchers will compare the control group and the intervention group to see if outdoor activities can protect myopia or not.

This is a Two-Stage Phase 1/2 study to evaluate the safety, tolerability and pharmacodynamics of CBT-009 eye drop in healthy volunteers. CBT-009 has the active ingredient of atropine, which at low doses, has shown to be effective in slowing down myopic deterioration. Current atropine products are prone to degradation once the container is open to the air. ADS Pharmaceutical has developed a novel atropine formulation.

The purpose of this prospective study is to assess the efficacy, safety and patient-reported outcomes of the Menicon Z Night orthokeratolgy contact lens for reducing myopia progression in children.

This study is designed to provide efficacy and safety data in patients with choroidal neovascularisation (CNV) secondary to myopia using an individualized as-needed (PRN) dosing schedule. Eligible patients who have provided written agreement to take part in the study will receive an intravitreal (into the study eye) injection of ranibizumab 0.5mg. Following eye examinations and tests at monthly clinic visits, the study doctor will repeat the injections on a monthly basis as required for an additional 11 months, in accordance with specified retreatment criteria. Patients will be in the study for approximately 12 months and will visit the hospital clinic 14 times over that period. The main assessments will include visual acuity tests, eye examinations, optical coherence tomography (OCT) to assess retinal thickness, fundus photography and fluorescein angiography (FA), measurement of intraocular pressure, blood pressure and pulse measurements and completion of health-related questionnaires'.

To demonstrate the efficacy of ranibizumab in combination with reduced-fluence verteporfin photodynamic therapy (RF-PDT) in patients with subfoveal choroidal neovascularization secondary to pathologic myopia (PM).

The objectives of this study are to evaluate the safety and efficacy of 3 dose groups (27, 36 and 45 mg/m2) of Combretastatin A-4 Phosphate for the treatment of subfoveal choroidal neovascularization in subjects with pathologic myopia.

The purpose of this study is to see if the drug bevacizumab is safe and effective to use for people with choroidal neovascularization (CNV). CNV is an eye condition where abnormal blood vessels grow in the part of the eye responsible for central (straight ahead) vision. The drug is produced using recombinant DNA technology and has been approved by the FDA for use in colon cancer. Although not yet approved for people with CNV, the FDA has given permission to use this drug in this study.

This study is designed to evaluate the efficacy and safety of two different dosing regimens of 0.5 mg ranibizumab given as intravitreal injection in comparison to verteporfin PDT in patients with visual impairment due to choroidal neovascularization (CNV) secondary to pathologic myopia (PM).

VEGF Trap-Eye will be tested for safety and efficacy in patients with vision loss due to choroidal neovascularization secondary to pathologic myopia. This will be a placebo-controlled trial. 3 out of 4 patients will receive an injection of VEGF Trap-Eye into the affected eye (and repeated injections if required), and 1 out of 4 patients will receive a sham injection requiring no needle stick, but making the patient unaware of whether or not he received active treatment. Outcome of the two treatment groups will be compared after 24 weeks. From week 24, sham patients may receive active treatment. Total duration of the study will be 48 weeks.
