Purpose To determine the prognostic value of pretreatment optical coherence tomography
(OCT) measurement of the peripapillary retinal nerve fibre layer (PRNFL) in final visual
outcomes of patients with anterior visual pathway meningioma and optic neuropathy.
Methods Retrospective case series from a tertiary care academic referral centre. Fourteen
eyes (12 patients) in which pretreatment and post-treatment OCT, visual field and
comprehensive neuro-ophthalmic exam data were available were evaluated for visual …

The article discusses research on anterior visual pathway meningiomas. It references the
study" Use of Optical Coherence Tomography in Predicting Post-Treatment Visual Outcome
in Anterior Visual Pathway Meningiomas," by JL Loo and colleagues in a 2013 issue of"
British Journal of Ophthalmology." The study has found no direct correlation between
pretreatment peripapillary retinal nerve fiber layer (PRNFL) mean thickness and post-
treatment visual function.
