Causes and risk factors
This condition is usually caused due to a frontal lobe tumor. Sometimes tumors from other sites may also be responsible.
Clinical presentation
One eye presents with optic atrophy, whereas the other eye presents with papilledema. The patient may develop central scotoma (loss of central vision), or sometimes even anosmia (loss of smell).
Additionally, the patient may develop other symptoms as a result of the intracranial tumor such as headache.
Investigations
Eye examination through fundoscopy is performed.
CT or MRI of the brain helps to detect the underlying tumor.
Treatment
The treatment is determined on the basis of the type and location of tumor. It may involve surgical excision of the tumor or radiation/chemotherapy.
When to contact a doctor
Contact a doctor as soon as you experience any visual problems, especially when associated with headache.
