Physician, Assistant Professor
Ophthalmology
Department: Ophthalmology
As a neuro-ophthalmologist at The Ohio State University Wexner Medical Center, I specialize in diagnosing and treating visual conditions that are caused by the nervous system. I have a passion for helping patients with complex neurological eye disorders and eye misalignment conditions, including crossed eyes.
Patients can always expect comprehensive and compassionate care when they come to see me. My goal is to help each patient manage their eye conditions and improve their quality of life.
Building long-term relationships with my patients is essential to me. My approach is based on having a deep understanding of each person’s unique medical history and needs, and I use this information to craft highly personalized care plans. I am committed to supporting my patients throughout their care journeys and working together toward their vision goals.
I am incredibly grateful for the mentors who have guided me throughout my career. Their expertise, support, and dedication inspire me to go above and beyond for my patients every day. I’m thrilled to be back at Ohio State and working alongside such talented and supportive colleagues. I look forward to contributing to our community and making a positive impact on our patients, our team, and future ophthalmologists.

My provider was kind enough to squeeze me in for a new medical problem. She was exceptional in every possible way. As a physician, I would like to believe I know what good looks like. She exceeded all exceptions and was exceptionally good. I cannot express how positive everything was.
I enjoy Dr. Casey as a provider. She is very thorough and explains medical issues well. She even laughed at my jokes.
Excellent
She was overall good, but she had to leave early to handle personal matters, which I did not appreciate, given that I had been at this appointment for FOUR HOURS. It would have been nice to have at least 5% of that time be with the actual physician. She did a decent job giving me information about the primary concern of the appointment, but was very dismissive of the secondary concern. It was clear she was following a basic protocol, especially when I have such a complex medical history which could be affecting the current problem.
She was knowledgeable and thorough.
Excellent

She did well, very kind and understanding
Always good
Dr. Casey was very professional, friendly, listened closely to my description of my vision condition, explained things well.
I waited an hour to see her. She was very thorough with the testing but my health history was not discussed. I had concerns about my double vision and if there was any correlation to my PMH. This was not addressed.
Excellent care
I was amazed how much she knew about my medical history!
Virtually all experiences in that clinic were positive.
Dr Casey was kind, caring and a good listener. She assessed my problem and came up with a solution which has worked well. Her plan for treatment was a very good plan.
Always professional and informative
My provider is compassionate and I trust her with my healthcare.
Very kind and made me feel comfortable, she took her time and explained what was going on and made a plan.
Provider was excellent in every respect.
Outstanding knowledge about my medical problem, the testing she provided showed exactly my condition, and her recommendation was very helpful and professional.
