Observation of Iris Blood Flow Via OCTA in Diabetic Neovascular Glaucoma

The goal of this observational study is to quantify iris blood flow via non-invasive eye scanning for evaluating ocular lesions in adults aged 18 years and older, including healthy volunteers, patients with type 2 diabetes mellitus (T2DM) without fundus lesions, T2DM patients with diabetic retinopathy (DR), and T2DM patients complicated with both DR and neovascular glaucoma (NVG). The main questions it aims to answer are: * Does iris blood flow fraction at six pupillary quadrants differ significantly among people with different stages of type 2 diabetic eye complications? * Are there quadrant-specific and gender-based differences in iris microcirculation changes caused by diabetic eye diseases? If there is a comparison group: Researchers will compare iris blood flow data from four groups (healthy controls, T2DM without DR, T2DM with DR, T2DM with DR + NVG) to see how iris blood circulation changes as diabetic eye conditions get worse, and test whether iris blood flow indicators can help identify patients with neovascular glaucoma. Participants will complete the following tasks: * Provide basic personal information, past medical history and recent laboratory test results from their routine medical records; * Receive a painless, non-invasive iris OCTA eye scan to capture iris blood flow images at six quadrants around the pupil.

Study to Learn More About Safety of Aflibercept Injection in Japanese Patients With Neovascular Glaucoma (NVG)

This is a prospective, observational, multi-center and post-authorization safety study that includes patients with a diagnosis of Neovascular Glaucoma. The investigator will have made the decision to use Eylea for treatment. The objective of this study is to assess safety and effectiveness of Eylea using in real clinical practice. Patients will be followed for a time period of 6 months from start of Eylea treatment or until it is no longer possible (e.g. lost to follow-up). In total, 480 patients will be recruited. For each patient, data are collected as defined in the electronic case report form (eCRF) at the initial visit, follow-up visit and final visit, either by routine clinical visits (as per investigators routine practice).

Minimally Invasive Suprachoroidal Drainage for the Treatment of Neovascular Glaucoma

To explore the efficacy and safety of minimally invasive suprachoroidal drainage for the treatment of advanced neovascular glaucoma

Effect of Subconjunctival 5-fluorouracil on the Outcome of Ahmed Valve in Neovascular Glaucoma

Neovascular glaucoma is a common and severe type of secondary closed-angle glaucoma. Topical treatments have variable effects and unfortunately often require surgery to control IOP. Although Glaucoma Drainage Device (GDD) such as Ahmed Glaucoma Valve (AGV) are a surgical choice in these patients, their effectiveness decreases over time. One of the main causes of failure in AGV surgery is the formation of scar tissue and fibrosis around the shunt plate. So, the aim of this study was to evaluate the effect of using MMC Intraoperative and 5FU Postoperative with AGV surgery in neovascular glaucoma patients according to a specific protocol, on the incidence of Hypertensive Phase (HP) and surgical success rate.

KDR2-2 Suspension Eyedrop in the Treatment of Neovascular Glaucoma (KDR-NVG) Trial

The clinical trial is aimed to evaluate the anti-neovascular effect of KDR2-2 suspension eyedrop in the treatment of neovascular glaucoma. Fourty subjects would receive either 0.96 or 3.84 mg/per day/eye, in a QID fashion, ×7 days (those without complications can continue to 28 days). The anti-neovascular effect of KDR2-2 on iris neovascularization would be evaluated at day 1, day 7, day 14, day 28 after KDR2-2 usage.
