Description of Clinical Expertise

Dr. Cui specializes in the diagnosis and management of glaucoma. She cares for patients at the Perelman Center for Advanced Medicine and at the Scheie Eye Institute. She performs surgeries to treat both cataract and glaucoma, including minimally invasive glaucoma surgery (MIGS). Dr. Cui’s clinical research interest includes assessing health-related quality of life in glaucoma patients who are candidate for MIGS.

Research Description:
Glaucoma is characterized by loss of retinal ganglion cells leading to permanent vision loss. It is the global leading cause of irreversible blindness and is projected to affect 112 million people worldwide by 2040. Elevated intraocular pressure is a well-known risk factor for disease onset and progression, and intraocular pressure reduction is the only therapeutic mechanism available to slow disease progression. However, glaucoma can continue to progress in a significant number of patients despite intraocular pressure normalization. Therefore, new therapies are urgently needed to prevent vision loss in patients suffering from glaucoma. My lab seeks to 1) elucidate the pathogenic mechanisms contributing to glaucoma, and 2) identify new and innovative therapies for glaucoma. My lab is actively evaluating GLP-1 receptors agonists as neuroprotective agents in glaucoma (Sterling et al. Cell Reports. 2020). In collaboration with the lab of Joshua Dunaief, we also demonstrated that iron chelation rescues retinal ganglion cells and promotes optic nerve axon survival following intraocular pressure elevation. In addition,we are characterizing a mouse with inherited deficits affecting the mitochondrial electron transport chain resulting in retinal ganglion cell loss as a model for normal tension glaucoma.
