NCT ID: NCT05835115 Completed - Myopia Clinical Trials

Development and Validation of a Deep Learning-based Myopia and Myopic Maculopathy Detection and Prediction System

Start date: April 1, 2022
Phase:
Study type: Observational

Myopia has become a global public health issue. Myopia affects the psychological health of children and adolescents and poses a financial burden. Therefore, early detection and prediction of children at a high risk of myopia development and progression are critical for precise and effective interventions. In this study, we developed a deep learning system DeepMyopia, based on fundus images with the following objectives: 1) to predict myopia onset and progression; 2) To detect myopic macular degeneration for AI-assisted diagnosis; 3) To predict the development of myopic macular degeneration; 4) evaluate its cost-effectiveness.

NCT ID: NCT03528122 Active, not recruiting - Retinal Detachment Clinical Trials

Amniotic Membrane for Recurrent Macular Hole

Start date: February 1, 2018
Phase: N/A
Study type: Interventional

Macular hole surgery were tried by different surgeons using many techniques with different successes but still there were many recurrences. In this study the investigators try to close these distinct types including recurrent holes using pre-prepared amniotic membrane.

NCT ID: NCT02122159 Withdrawn - Clinical trials for Myopic Macular Degeneration

Research With Retinal Cells Derived From Stem Cells for Myopic Macular Degeneration

Start date: March 2013
Phase: Phase 1/Phase 2
Study type: Interventional

Pathologic myopia is a major cause of legal blindness worldwide. In myopic macular degeneration (MMD), there is degeneration of the retinal pigment epithelial (RPE) layer, and associated photoreceptors, resulting in vision loss. There is currently no standard treatment for MMD. Transplantation of intact sheets of RPE and suspensions of isolated individual RPE cells as well as autologous translocation of RPE cells has been attempted as treatment for AMD. Human photoreceptors are comprised of two cell types-rods and cones. Both have a close relationship with the outermost retinal cells, the retinal pigmented epithelium (RPE). The RPE is located between the choroid and the photoreceptors. The RPE maintains photoreceptor function by recycling photopigments,delivering, metabolizing and storing vitamin A, phagocytosing rod photoreceptor outer segments, transporting iron and small molecules between retina and choroid, maintaining Bruch's membrane and absorbing stray light to allow better image resolution. In essence, the RPE layer is critical to the function and health of photoreceptors and the retina as a whole. Human PRE (hRPE) transplantation may be a viable option for treatment of degenerative diseases of the retina. MA09-hRPE cells are fully differentiated human RPE cells derived from embryonic stem cells. Transplanted hRPE cells prepared by Advanced Cell Technology have been studied in rodent models of macular degenerative disease. The data suggests that the subretinal injection of ACT's hRPE cell products rescues, or at least delays, loss of visual function in two animal models of retinal degenerative diseases. The main purpose of this study is to evaluate the safety and tolerability of MA09-hRPE cellular therapy in patients with Myopic Macular Degeneration (MMD). Another objective is to evaluate potential efficacy endpoints to be used in future studies of RPE cellular therapy.
