Correlation between Optical Coherence Tomography and Optic Nerve Head Swelling Due to Pseudotumor Cerebri

Clinical management of patients with pseudorumor cerebri (PTC) relies upon the monitoring of subjective symptoms of headache and visual symptoms, as well as objective measurements ofvisual acuity, visual fields, and optic nerve head (ONH) swelling. The Frisen scale is often used to grade papilledema; however, it may have significant interexamination variability between different examiners. Optical coherence tomography (OCT) of the peripapillary nerve fiber layer (NFL), performed routinely for eyes with open angle glaucoma, might provide a quantitative measurement of ONH elevation in patients with PTC, thereby aiding in their clinical management. We studied the relationship between OCT measures ofmacular and NFL thickness and gtades ofONH swelling based on clinical grading score determined by an experienced neuro-ophthalmologist.
