Definition: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: 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.
Which is the apt title for the abstract? option1: Nerve fibre bundle visual field defects and intracranial mass lesions. option2: Comparison of subcutaneous injection and high-dose inhalation of epinephrine--implications for self-treatment to prevent anaphylaxis.
Output:
Nerve fibre bundle visual field defects and intracranial mass lesions.
