Perimetric findings in pseudotumor cerebri using automated techniques

Area of Science:

• Ophthalmology
• Neurology

Background:

• Pseudotumor cerebri (idiopathic intracranial hypertension) is a condition characterized by increased intracranial pressure.
• Visual field defects are a known complication, but their prevalence and severity require further elucidation.

Purpose of the Study:

• To assess the prevalence and severity of visual field defects in patients with pseudotumor cerebri using automated static threshold perimetry.
• To compare findings with previous studies utilizing manual kinetic perimetry.

Main Methods:

• Automated static threshold visual fields were performed on 44 eyes of 22 patients diagnosed with pseudotumor cerebri.
• Severity of papilledema was graded (severe or atrophic in 20 eyes).

Main Results:

• Severe visual field defects were observed in 9% of eyes.
• Moderate visual field defects were found in 68% of eyes.
• Comparison with prior studies indicated a higher incidence of moderate defects with automated static perimetry (68% vs. 34%).

Conclusions:

• Automated static threshold perimetry reveals a high prevalence of visual field defects in pseudotumor cerebri.
• The findings suggest visual field defects in this condition may be more common and potentially more severe than previously reported.
• Severe or atrophic papilledema was consistently associated with abnormal visual fields.
