Corneal neovascularization

Researchers compare two versions of corneal crosslinking to treat corneal neovascularization, a condition where abnormal blood vessels grow into the clear front surface of the eye. Both versions use riboflavin eye drops followed by ultraviolet A light, but one shines the light fo…

This study tests a two-step treatment for corneal neovascularization, where abnormal blood vessels grow on the clear front part of the eye. First, doctors use a fine needle with heat to seal off the vessels, then inject a drug called bevacizumab to prevent regrowth. The trial wil…

This study tests whether giving a laser treatment (transscleral cyclophotocoagulation) to lower eye pressure before a Boston keratoprosthesis (a plastic cornea implant) can prevent or slow glaucoma. Twenty adults who need the implant will receive one of two laser types 4-8 weeks …

This study tests whether injecting anti-VEGF medication directly into the cornea can safely reduce abnormal blood vessel growth caused by herpes simplex keratitis. One hundred adults will receive either the injection plus antiviral eye drops or standard antiviral drops alone. Res…

This study aims to find biological markers (biomarkers) in blood, tears, and eye cells from 110 adults with seven rare eye diseases. Researchers will compare these markers between patients and healthy controls to see if they differ and if they relate to disease symptoms. The goal…

This long-term study collects data from over 100 eye clinics in Germany to see how corneal transplant surgeries have changed since 2001. Researchers track the number of surgeries, the types of procedures used, and the reasons people need them. The goal is to understand trends, no…

This study gathers eye scan images from 180 people with healthy eyes or eye diseases like glaucoma and retinal disease. The goal is to collect data using a new optical coherence tomography (OCT) device called A10900. No treatment or medication is given. The information will help …
