A 61-year-old male presents with diplopia of acute onset and progressive course. He has a history of previous intracranial haemorrhage that was surgically evacuated 7 years ago and was also associated with diplopia. Examination revealed left complete oculomotor nerve paralysis with a fixed and dilated left pupil. Computed tomography (CT) revealed encephalomalacia, evidence of previous craniotomy, and an incidental left parietal convexity meningioma. CT angiography of the brain revealed a left tortuous duplicate middle cerebral artery with fenestration of its proximal part, an anterior communicating artery aneurysm, and a characteristic capillary blush of the meningioma...

Idiopathic intracranial hypertension is a syndrome of elevated intracranial pressure without an identifiable cause. The majority of cases appear to be sporadic, and incidence is highest in obese women of childbearing age. The role of genetics in the pathophysiology of the disease is unclear, and familial cases are rare. We report a familial occurrence in a mother and her twin, 5-year-old sons.

Hypotension is the most frequent complication of haemodialysis. We report a case of acute visual impairment after one session of haemodialysis in a context of an acute optic neuropathy. The immunological and serological studies were negative. The records of hypotension greater than usual after the dialysis session that coincided with the visual complaints strongly suggest the dialysis-induced hypotension is the underlying mechanism of this non-arteritic anterior ischemic optic neuropathy.

A 73-year-old female with a past medical history of breast cancer, who 10 years earlier experienced complete remission, complained of bilateral visual field disturbances and photopsia, 2 months prior. Tumour recurrence and metastatic lesions were not found during the medical examination, but antibodies against recoverin were detected in her serum. Despite immunosuppressive treatment with prednisolone and plasmapheresis, rapid and diffuse degeneration of the patient's photoreceptors and deterioration of her visual field were observed...

Authors describe a case of traumatic pseudoaneurysm of cavernous internal carotid artery in a young male who presented with complaints of progressive decrease in vision, inability to move the eye, and delayed epistaxis 8 months after the head injury sustained during a motor vehicle accident. The presence of optic atrophy and epistaxis in the setting of head trauma alerted the authors to look for this potentially life-threatening condition. Timely intervention in the form of endovascular coil occlusion of the internal carotid artery was performed and the epistaxis stopped without any ischaemic or thromboembolic sequaelae...

REVIEW
Abidemi Idowu Otaiku
A rare condition characterized by a transient inability to open one or both eyes upon awakening from sleep was first described in 1897. Although less than a handful of papers have been written about this condition since its initial description, a well-defined clinical entity emerges from the available literature. This article reviews the history and clinical features of this unusual condition.

PURPOSE: To determine the positive yield (utility rate) of temporal artery biopsy (TAB) in patients with suspected giant cell arteritis (GCA). STUDY DESIGN: Systematic review (CRD42017078508) and meta-regression. MATERIALS AND METHODS: All articles concerning TAB for suspected GCA with English language abstracts from 1998 to 2017 were retrieved. Articles were excluded if they exclusively reported positive TAB, or only cases of known GCA. Where available, the pre-specified predictors of age, sex, vision symptoms, jaw claudication, duration of steroid treatment prior to TAB, specimen length, bilateral TAB, and use of ultrasound/MRI (imaging) were recorded for meta-regression...

Reliable visual field testing is the gold standard in identifying future vision loss in patients with Idiopathic Intracranial hypertension (IIH). However, when field performance is unreliable, GCC analysis may be useful. We evaluated IIH patients over three visits: initial visit, follow-up visit and a third visit, almost 1 year later. We evaluated mean deviation (MD), GCC and RNFL at presentation and the second visit and compared it to the mean deviation (MD) on fields at the third visit. As early as the second visit, GCC loss correlated with visual field results seen at the third visit...

A recent study found that increased optic canal area on magnetic resonance imaging was associated with worse papilloedema in idiopathic intracranial hypertension (IIH). We repeated this study using more accurate computerized tomography derived measurements. Optic canal dimensions were measured from 42 IIH patients and 24 controls.  These were compared with papilloedema grade.  There was no correlation between any of the optic canal measurements and papilloedema grade and no significant difference in optic canal measurements between patients and controls...

The management of patients with cerebrospinal fluid disorders requires a multi-specialty approach involving specialists in neurosurgery, neurology, neuroradiology and neuro-ophthalmology. A symposium on CSF disorders was organised by the clinical and academic teams at University Hospitals Birmingham, United Kingdom. The meeting featured a synopsis of the latest scientific research on CSF disorders. Some of the more challenging and controversial issues facing the multi-speciality team were presented and discussed...

Bilateral intracavernous internal carotid artery aneurysms are rare. They are more common in elderly females and are associated with hypertension. We present the computed tomography angiography findings of an 81-year-old female with history of hypertension who came complaining of diplopia and headache. Examination revealed bilateral sixth nerve palsy with left third nerve palsy. External ocular examination was normal. Computed tomography angiography was done and revealed bilateral intracavernous internal carotid artery aneurysms...

Ocular features of Gaucher disease include gaze abnormalities, corneal clouding, ocular deposits and pigmentary changes in the macula. We report the presence of bilateral fovea sparing macular deposits in a 21-year-old woman with type 3 Gaucher disease. Macular deposits occur due to glucocerebroside accumulation within histiocytes and retinal deposits might correlate with the degree of systemic infiltration.

A 62-year-old male with a history of metastatic clear cell renal cell carcinoma (ccRCC) presented with decreased vision to 20/50 in the left eye. Fundus examination revealed an elevated, amelanotic mass lesion in the superotemporal macula, without involvement of the central macula by subretinal fluid or tumour. Given incongruity between the fundus findings and the degree of visual impairment, visual field testing was obtained, revealing a bitemporal hemianopia. Magnetic resonance imaging demonstrated optic chiasm compression by a pituitary mass, which had previously been overlooked on computed tomography imaging...

An 84-year-old woman presented with 3 months of vertical binocular diplopia and difficulty reading at near. She had a history of bilateral ophthalmic artery aneurysm repair involving use of muslin in the 1990s. The patient then developed bitemporal hemianopsia secondary to muslin-induced inflammation ("muslinoma") extending to the optic chiasm, which required surgical decompression. She had a persistent bitemporal hemianopsia but was stable for two decades after surgery. In 2017, the patient re-presented with double vision...

REVIEW
Edward Palmer, Jesse Gale, Jonathan G Crowston, Anthony P Wells
Optic nerve head drusen are benign acellular calcium concretions that usually form early in life, just anterior to the lamina cribrosa. Improving imaging using optical coherence tomography suggests they are common and may be present in many clinically normal discs. These drusen may change in appearance in early life, but are generally stable in adulthood, and may be associated with visual field defects, anterior ischaemic optic neuropathy, or rarer complications. Based on long-term clinical data and optical coherence tomography, we propose a refined hypothesis as to the cause of optic disc drusen...

The purpose of this study was to evaluate retinal thickness in different Xeroderma Pigmentosum (XP) complementation groups using spectral-domain optical coherence tomography (SD-OCT). This was a cross-sectional pilot study of 40 patients with XP. All patients had healthy-looking retinae and optic nerves on slit lamp biomicroscopy, and subtle or no neurological deficits. Patients were divided into two groups based on the known tendency for neurodegeneration associated with certain XP complementation groups. A third control group was obtained from a normative database...
