Purpose: To describe a case of a suprasellar meningioma compressing the chiasm from below and producing a unilateral fascicular (nasal) visual field defect that mimicked glaucomatous cupping. Case report: A 78-year-old man presented with painless, progressive, unilateral arcuate visual field defect. He was diagnosed with “normal tension glaucoma” based on an asymmetric cup to disc ratio. Despite treatment with anti-glaucoma drops, the visual field defect progressed. Neurophthalmic evaluation was consistent with a compressive optic neuropathy OD. Brain MRI showed a suprasellar meningioma compressing on the junction of the optic nerve and chiasm from below. Conclusion: Although junctional visual field loss (e.g. junctional scotoma and junctional scotoma of Traquair) are well-known presentations of compressive lesions at the optic chiasm, we describe a monocular, ipsilateral compressive superior nasal defect and asymmetric cupping as the presenting sign of a junctional compressive lesion mimicking glaucomatous cupping.

Abstract Purpose To investigate the relationship of ocular blood flow (via arteriovenous passage time, AVP) and contrast sensitivity (CS) in healthy as well as normal tension glaucoma (NTG) subjects. Design Mono-center comparative prospective trial Methods Twenty-five NTG patients without medication and 25 healthy test participants were recruited. AVP as a measure of retinal blood flow was recorded via fluorescein angiography after CS measurement using digital image analysis. Association of AVP and CS at 4 spatial frequencies (3, 6, 12, and 18 cycles per degree, cpd) was explored with correlation analysis. Results Significant differences regarding AVP, visual field defect, intraocular pressure, and CS measurement were recorded in-between the control group and NTG patients. In NTG patients, AVP was significantly correlated to CS at all investigated cpd (3 cpd: r =  − 0.432, p< 0.03; 6 cpd: r =  − 0.629, p< 0.0005; 12 cpd: r =  − 0.535, p< 0.005; and 18 cpd: r =  − 0.58, p< 0.001), whereas no significant correlations were found in the control group. Visual acuity was significantly correlated to CS at 6, 12, and 18 cpd in NTG patients (r =  − 0.68, p< 0.002; r =  − 0.54, p< .02, and r =  − 0.88, p< 0.0001 respectively), however not in healthy control patients. Age, visual field defect MD, and PSD were not significantly correlated to CS in in the NTG group. MD and PSD were significantly correlated to CS at 3 cpd in healthy eyes (r = 0.55, p< 0.02; r =  − 0.47, p< 0.03). Conclusion Retinal blood flow alterations show a relationship with contrast sensitivity loss in NTG patients. This might reflect a disease-related link between retinal blood flow and visual function. This association was not recorded in healthy volunteers.

In Pregnancy

Pituitary apoplexy in pregnancy is a potentially fatal condition caused by acute ischaemic infarction or haemorrhage of pre-existing pituitary adenoma or within a physiologically enlarged pituitary gland. It has a wide spectrum of clinical presentations ranging from a mild headache to sudden collapsed. Here, we report a life-threatening case of pituitary apoplexy in a non-functioning pituitary macroadenoma occurring during pregnancy that presented with bilateral blurring of vision. Visual field showed bitemporal superior quadrantanopia. Urgent non-contrast brain MRI revealed an acute expansion of a hemorrhagic pituitary lesion complicated with local compression to the optic chiasm. The patient underwent an uneventful right supraorbital craniotomy and excision of the tumour under general anaesthesia with no foetal loss. The repeated visual field at 2 weeks after surgery showed recovering visual field defect. Hence, early neurosurgical intervention is advisable to prevent mortality and morbidity due to permanent visual field loss.
