Summary
This case report details a woman diagnosed with idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri. Early diagnosis and treatment of asymmetric papilledema are crucial for preventing vision loss.
Area of Science:
- Ophthalmology
- Neurology
Background:
- Idiopathic intracranial hypertension (IIH), or pseudotumor cerebri, is a condition characterized by increased intracranial pressure without a clear cause.
- Papilledema, or optic disc swelling, is a key sign of IIH, but can present asymmetrically.
Observation:
- A 50-year-old woman presented with headache and transient visual blurring in one eye.
- Initial examination revealed unilateral optic disc edema, with normal visual acuity and pupillary responses.
- Further investigations, including neuroimaging and lumbar puncture, were necessary after excluding ocular causes.
Findings:
- The patient was diagnosed with idiopathic intracranial hypertension.
- Symptoms improved with acetazolamide treatment and lumbar punctures.
- Subsequent detailed fundoscopy confirmed mild papilledema in the other eye, highlighting the diagnostic challenge of asymmetric presentations.
Implications:
- Asymmetric or apparently unilateral papilledema can be an early sign of increased intracranial pressure.
- This case underscores the importance of considering neurological conditions even with seemingly localized ocular findings.
- Prompt neurological evaluation is essential for timely diagnosis and management of IIH to prevent potential vision impairment.
