INTRACRANIAL MASS LESIONS. Intracranial tumors, aneu-rysms, hemorrhages, and inflammatory processes might manufacture headaches as results of a rise in intracranial pressure and other factors. Increased intracranial pressure, whether or not due to tumor or not, can virtually continuously be in the middle of headache. The presence of papilledema due to increased intracranial pressure serves as a helpful aid in diagnosis. The examination of the optic disc for early papilledema is therefore vital in patients with headache. In order to get all attainable information from the examination of the fundus, it is best to record methodically one’s observations as to the disc margins, disc color, presence or absence of physiologic cup, and the characteristics of the retinal vessels. In early papilledema, the disc margins might become obscured, the disc becomes hyperemic, the physiologic cup becomes filled in, and the veins become engorged.

In view of the variability of the looks of normal discs in different people, a record of previous examinations of a patient’s fundus might be invaluable.
For example, if the record shows that a patient previously had a good physiologic cup, venous pulsations and discrete temporal margins, and if that patient now complains of headache and the fundus shows a loss of the cup, no venous pulsations and a blurring of the margins, this is often good evidence of early increased intracranial pressure. In all such cases the dimensions of the patient’s blind spot must be plotted carefully on the tangent screen. Since the dimensions of the normal blind spot is thought well enough to be used for clinical purposes and definite enlargement is highly characteristic of papilledema, the measurement of the blind spot is of great importance in evaluating the presence or absence of papilledema due to increased intracranial pressure.

If the looks of the disc with the dimensions of the blind spot should still leave doubt as to the presence or absence of papilledema, a careful recording of the fundoscopic and tangent screen findings must be created for comparison with future examinations at some appropriate interval; for example, many days or a week, relying on the severity of the symptoms. In such cases, so as to detect minimal changes, minimal techniques must be used.
Conditions seemingly to be confused with papilledema are optic neuritis (papillitis), vascular neuroretinopathy, drüsen (hyaline bodies of the optic nerve head), and medullated nerve fibers. Optic neuritis differs clinically from papilledema in its sudden onset and the presence of pain and acute loss of vision. The visual field defect is that of a cecocentral, cecoparacentral, or, sometimes, peripheral nerve fiber bundle defect. In early papilledema, on the other hand, there is only enlargement of the blind spot. With progression there is insidious involvement of the fixation area after a relatively long period of time, and transitory episodes of blurring of vision.
