NCT04787471
The study objective is to assess safety and efficacy of photo-activation of riboflavin for treatment of corneal neovascularization with or without concomitant inflammation and/or infection.
NCT00555594
To determine the effect of subconjunctival Bevacizumab in corneal neovascularization
NCT05659940
The purpose of this study is to determine whether a novel subset of neutrophils is correlated with corneal neovascularization in the patients suffered from ocular chemical injury.
NCT02797704
The goal of this current study is to prospectively evaluate the influence of a single subconjunctival aflibercept injection on the regression of corneal neovascularization. Twenty patients with corneal neovascularization who are candidates for anti VEGF treatment (by the discretion of a corneal specialist) will be included in this study. The patients will be treated with a single subconjunctival injection of 0.08 ml aflibercept (25 mg/ml) in a single quarter of the conjunctiva, near the limbus in a proximity to the area of pathological neovascularization. Regression of neovascularization will be documented.
NCT00769145
The primary purpose of this trial is to evaluate the safety and tolerability of ranibizumab given via subconjunctival injection in patients undergoing corneal transplantation.
NCT02042027
The purpose of the study is to test the investigational drug Gamunex-C on the growth of blood vessels over the cornea. This study is being conducted by Dr. Balamurali Ambati at the Moran Eye Center at the University of Utah. The cornea is the clear outer front part of the eye. In corneal neovascularization, blood vessels grow over the cornea. Corneal neovascularization and ocular anterior segment inflammations are sight-threatening conditions. Lipid deposition and edema with subsequent scar formation can compromise corneal clarity irreversibly. Corneal neovascularization is also a well recognized risk factor for corneal graft failure. In its natural state, the cornea is a site of immune privilege well suited to tissue transplantation. Once vascularized, there is direct exposure of corneal antigens to circulating host immune mechanisms greatly increasing the chance of rejection \[Collaborative Corneal Transplantation Study\]. Melting or inflammation in the anterior chamber, cornea, or ocular surface can cause irreversible scarring or destruction of the optical elements of the eye, which can compromise vision. Current standard of care for such conditions includes use of topical steroids and sometimes immunosuppressants (e.g., cyclosporine). These do not address a common underlying corneal neovascularization or melting. This is a Phase 1 clinical trial of subconjunctival IVIg (Gamunex-C) injection for treatment of corneal neovascularization in the setting of corneal transplantation with neovascularization. Candidates for corneal transplantation with corneal neovascularization in one or more quadrants crossing more than 0.5mm over the limbus will be identified for inclusion in our study.
NCT00515684
The purpose of this study is to determine whether topical bevacizumab is safe or not when used in corneal neovascularization for long term period.
NCT00004430
OBJECTIVES: I. Demonstrate the safety and efficacy of dihematoporphyrin derivative (DHP) in laser photodynamic therapy (PDT) in patients with corneal neovascularization. II. Document the histopathologic mechanism of action in selected patients undergoing penetrating keratoplasty following PDT therapy for corneal neovascularization. III. Facilitate FDA product approval of DHP as a photosensitizing agent for laser treatment in these patients. IV. Explore the use of this photosensitizer for ocular and cutaneous basal cell and squamous cell carcinoma.
