Navigating the Uncharted: A Rare Case of Ocular Flutter and Intermittent Jaw Movements in a Case of Chronic Lymphoid...

Although chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western world, neurologic complications arising from direct leukemic involvement of the nervous system are reported in only 1% of patients with CLL. Ocular involvement in CLL, direct or indirect, is less known and exceptionally rare. This case involves a 63-year-old female with CLL undergoing chemotherapy for a year, who recently presented with unusual eye movements in the horizontal plane (ocular flutter), resting and intentional tremors in the right upper and lower limbs, and intermittent jaw movements. With no established protocol for CLL with central nervous system involvement, collecting case data becomes crucial for determining optimal treatment and diagnostic approaches early on.
