Ongoing studies
- RECOVER Gensight LHON study - first on-site meeting achieved. Recruiting Dr. Martel retinal faculty for IV injections, recruiting Dr. Gallagher as well, working with our IRB liaison, Carla Aubourg.
- VIRES group has resulted in several publications on neurosurgical approaches using HDFT.
- 2018 – present: Creating a longitudinal database of subjects with PCA strokes to study using OCT, fMRI, and DTI techniques in collaboration with CMU and Dr. Bradford Mahon of the University of Rochester.
Book chapters
- Giant cell arteritis-associated ocular vascular diseases, Marie-Helene Errera, Thomas M. Pearce, and Gabrielle Bonhomme. Retinal and Choroidal Vascular Diseases of the Eye 1st Edition, Jay Chhablani, MD Editor, Elsevier Books, March 2024
Dr. Bonhomme's research interests include improving the evaluation of the efficacy of venous sinus stenting in subjects with vision loss due to IIH (OPEN-UP study), the diagnosis of para-neoplastic syndromes affecting the vision of subjects with lung cancer, creating an algorithm to predict post-operative results in subjects with vision-threatening anterior visual pathway tumors, creating a multi-disciplinary longitudinal database of subjects with PCA strokes to study using OCT, fMRI, and DTI techniques, and investigating the use of HDFT MRI post-processing technique in pre-operative planning.
- 2012 - present: CAR study/ PATHs Award - University of Pittsburgh Medical School PATHS Pilot Program Grant to be used to fund this pilot study on improving the diagnosis of para-neoplastic syndromes affecting the vision of subjects with lung cancer.
