Filter by:Based on the progress of cataract surgery, intraocular lens development, vitreoretinal surgery and anesthesia technology in recent years, the purpose of this study is to develop a new type of more accurate and minimally invasive combined surgery for cataract and fundus diseases, and to evaluate the advantages and value of the surgery as well as related complications, so as to minimize the surgical trauma and obtain faster visual function recovery and better patient comfort. To provide new solutions for the growing demand of eye health care.
The purpose of this study is to compare the efficiency and safety of ultrahigh-speed cut rate 27-gauge system (27+®GA HYPERVIT® Vitrectomy Probe (Alcon Laboratories, Fort Worth, TX, USA)) and standard cut rate 27-gauge vitrectomy system (27+®GA Advanced ULTRAVIT® Vitrectomy Probe (Alcon Laboratories, Fort Worth, TX, USA)).
Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases
Group 4a and 4b was an FDA trial that showed that patients who have an Amsler grid abnormality on paper, have a similar abnormality on the app. Group 7a and 7b was an FDA trial that showed that normal patients do not have false positives on the Amsler app as well as on the Amsler paper version. Further Vision on the app is slightly better than vision on the standard Sloan near card using a formula (vision is 7/10th of a line better on the app).
A study to assess the utility of human polarization pattern perception for the detection, diagnosis and monitoring of eye disease
We evaluated preoperative and postoperative optical coherence tomograpghic images in eyes with full thickness macular hole (FTMH) whether the epiretinal proliferation (EP) was detected and detection of EP was correlated to the visual improvement.
We evaluate the intraoperative optical coherence tomographic (OCT) images of eyes with idiopathic macular hole (MH) or lamellar macular hole whether the intraoperative OCT findings will affect postoperative visual outcome.
Macular diseases often cases severe visual impairment. Recent clinical introduction of anti-vascular endothelial growth factor agents may change the clinical course of various macular diseases, including age-related macular degeneration (AMD), polypoidal choroidal vasculopathy (PCV), retinal angiomatous proliferation (RAP), central serous chorioretinopathy (CSC), myopic choroidal neovascularization (CNV), retinal vein occlusion (RVO), diabetic macular edema (DME), and so forth. The advance in vitrectomy improve visual outcomes in some maculae diseases, including epiretinal membrane (ERM), macular hole (MH), vitreomacular traction syndrome (VMTS). Patients with such macular diseases are registered and are followed up for 5 years with appropriate treatment for each patient. By the analysis of the correlation between initial examinations and final visual acuity, factors associated with good visual prognosis will be elucidated.

The objective of this research is to determine the effects of anti-VEGF drugs (bevacizumab, ranibizumab or aflibercept) on aqueous humor dynamics (AHD) in patients with retinal vascular disease. The underlying hypothesis is that anti-VEGF drugs increase intraocular pressure (IOP) by increasing aqueous inflow, decreasing uveoscleral outflow or both. The specific aim is to evaluate the changes produced in AHD after 1 baseline and a subsequent 1 monthly injection of anti VEGF agents.
