Marfan syndrome, ectopia lentis, lensectomy, visual and surgical result
Eighty-two eyes of 41 patients with a genetically proven diagnosis of Marfan syndrome were retrospectively analysed. Twenty-seven had bilateral subluxation and 14 received lensectomy. Follow-up was three years. Mean visual acuity (VA) was 0.1 ±0.7 logMAR in patients with normal...

Glaucoma
This study investigated the retinotopic functional representation in the visual cortex of mild to moderate primary open-angle glaucoma (POAG) participants and age-matched normal volunteers, using wide-view visual presentation, high-resolution retinotopic stimuli, and high-resolution blood oxygenation level dependent (BOLD) functional magnetic...

Idiopathic intracranial hypertension, predictors, visual outcome
This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Neuro-Ophthalmology
The authors present a retrospective cohort study to evaluate key predictors of long-term high-contrast visual acuity following optic neuritis associated with multiple sclerosis. All patients coded as optic neuropathy and assessed by a neuro-ophthalmologist over a 10-year period were screened...

Idiopathic intracranial hypertension, Pseudotumor cerebri, visual outcome
Idiopathic intracranial hypertension (IIH) is a clinical syndrome characterised by headache and papilloedema that can lead to significant visual morbidity. IIH is diagnosed by the modified Dandy criteria, which include normal neuroimaging and cerebrospinal fluid (CSF) composition, high CSF opening...

functional visual field loss, optic nerve, perimetry, visual fields
Functional visual field loss is traditionally assessed by kinetic perimetry, typically producing spiralling isopters. This study looked at the spatial distributions of functional field deficits using automated static perimetry. A retrospective review of automated perimetry records was conducted using a...
