Optical coherence tomography analysis of eyes in patients with chronic chiasmal compression: A case report

Introduction. Olfactory groove meningiomas cause progressive compression of the frontal lobes with posterior projection towards sella turcica. If large enough, these tumors may optic nerve and chiasm. The aim this study was to determine whether optical coherence tomography, as a method that objectively measures thickness retinal fiber layer ganglion cell complex thickness, provides realistic assessment postoperative visual outcome in chronic chiasmal caused by olfactory meningioma. Case Report. A 55-year-old woman presented an eight month history malaise, weakness, headaches, anosmia, blurred vision both eyes. Magnetic resonance imaging endocranium revealed meningioma extending into prechiasmal portion nerves chiasm marked compressive effect. mean preoperative fibre 65 ?m right eye 63 left eye. Ten months after surgery, 67 57 eye, while it could not be measured due loss fixation. 56 48 obtained values were significantly lower than physiologic values. Conclusion. Retinal tomography represent valid prognostic indicator recovery surgical decompression
