Diagnosis of Papilledema
Clinical evaluation Immediate neuroimaging The degree of disk swelling can be quantified by comparing the plus lens numbers needed to focus an ophthalmoscope on the most elevated portion of the disk and on the unaffected portion of the retina. Swelling can also be quantified by measuring nerve fiber layer thickness using Optical coherence tomography (OCT); OCT is done to quantify the degree of papilledema so that changes can be monitored. Differentiating papilledema due to elevated intracranial pressure from other causes of a swollen optic disk, such as Optic Neuritis ,
