The Pituitary Tumor and Vision Change Clinic, held every Monday at the Mischer Neuroscience Associates (MNA) clinic in Suite 2800 of the Memorial Hermann Medical Plaza, provides state-of-the-art care for patients experiencing problems from pituitary and parasellar tumors.

An early and precise diagnosis is necessary for patients with pituitary and other parasellar tumors, which may cause a wide range of disorders and present with a variety of symptoms, including hormonal changes, vision loss and infertility. Led by Dr. Arthur Day, M.D., the Pituitary Tumor and Vision Change Clinic brings together the diverse range of physicians needed to accurately diagnose and evaluate each case, including a neuro-ophthalmologist and endocrinologist who are available for consults as needed.

Dr. Arthur Day is affiliated with Memorial Hermann Health System.

Integrative Approach to Patient Care

Seeking patient satisfaction and outstanding clinical outcomes, the Pituitary Tumor and Vision Change Clinic operates under an integrative approach. Clinic physicians evaluate each patient’s case and incorporate neurology, endocrinology, neuro-ophthalmology, stereotactic radiosurgery, diagnostic radiology, interventional neuroradiology, radiation oncology and pathology for a comprehensive diagnosis and treatment plan.

This collaborative system is modeled after that of the Clinic’s parent organization, the world-class Mischer Neuroscience Institute. A long-standing partnership between Memorial Hermann-Texas Medical Center and The University of Texas Health Science Center at Houston (UTHealth) Medical School, MNI was one of the first institutions in the country to integrate neurology, neurosurgery, neuroradiology and neurorehabilitation. MNI is the largest neuroscience program in Texas, and continues to draw clinicians, researchers and patients from all over the world.
