Detailed Instructions: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
Problem:Abstract: Nerve fibre bundle visual field defects are the hallmark of pathology at the optic nerve head or retina. In the present series, six eyes of four patients with large intracranial mass lesions demonstrated such field defects with visual acuity spared in three of the involved eyes. In no cases did visual function in the opposite eye offer a clue to the localization of the lesion.
Question: Does the abstract contain any numerical data?
Solution:
No
