“…Although visual disturbance and headache has been quoted in various studies as the presenting symptom, the mechanism for this 2 symptoms in SRT is totally different. Visual disturbance in sellar tumors are due to the compression or mass effect exerted on optic apparatus mainly at optic chiasm (18,19). Levy et al has proposed the headache particularly in pituitary tumor patients is not mere structural problem but rather might have neuroendocrine and biochemical basis to it (15).…”

“…Close anatomical proximity of sellar region with optic apparatus causes significant number of tumors to present with visual disturbance which vary from mild visual field (VF) defect to blindness (3). Cause for this symptoms are due to the compression of afferent pathway of vision mainly at the region of optic chiasm which lies in this anatomical region (19).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
