Abstract：
Transient visual obscurations (TVOs) represent brief ischaemic events of the optic nerve. These most commonly occur in the setting of raised intracranial pressure or more localised aetiologies within the orbit that result in decreased perfusion pressure. Transient vision loss has rarely been associated with pituitary tumours or optic chiasm compression, but details are lacking. We describe classic TVOs that completely resolved following resection of a pituitary macroadenoma causing chiasmal compression with a relatively normal eye examination. Clinicians should consider neuro-imaging in patients with TVOs and a normal evaluation.
摘要：
瞬时视觉遮挡（TVOs）代表视神经的短暂缺血事件。这些最常见于颅内压升高或眼眶内更局部化的病因，导致灌注压降低。短暂性视力丧失很少与垂体肿瘤或视交叉压迫有关，但缺乏细节。我们描述了经典的TVOs，这些TVOs在切除垂体大腺瘤后完全解决，导致交叉压迫，并进行了相对正常的眼部检查。临床医生应考虑对TVOs患者进行神经成像和正常评估。
