Static subjective visual vertical (SVV) in the normal visual system

Graviception is the perception of a persons’ orientation relative to gravitational force. This can be measured by means of subjective verticals, which can be divided into three tests: subjective visual vertical (SVV), subjective postural vertical (SPV) and subjective haptic vertical...

Proprioception and ptosis

This is a small prospective study investigating the effect of proprioceptive factors on upper lid height. Eight unilaterally anophthalmic patients with ocular prostheses and normal lid heights had standardised photographic measurements taken of their eyelid and brow positions. Three sets...

Comparison of central laminar thickness in optic neuropathy and normal eyes

The study compares central laminar thickness (LT) among patients with glaucomatous optic neuropathy (GON), patients with non-GON and normal subjects. The non-GON group comprised eyes with demyelinating optic neuropathy (ON), anterior ischaemic ON, compressive ON, Leber hereditary ON and traumatic...

Cataract surgery and circadian photoentrainment

The study authors sought to investigate the possible effects of circadian photoentrainment following cataract. This was a randomised clinical trial, where 76 eyes of 76 patients (with bilateral cataract) were randomised to blue-blocking or neutral intraocular lenses (IOLs). Outcome measures...

Normal videonystagmography data

The authors report on the smooth pursuit and saccadic eye movement waveforms elicited from normal patients while viewing standardised calibrated targets. Serial trials were performed on each patient to determine test / retest reliability: nine trials producing 117 results by...

Evaluating ocular motor functions

Traditionally orthoptists are specialised in assessing ocular motor disorders. This article introduces the ocular motor score as a new clinical tool for screening and follow-up for children and young adults. The protocol consists of 15 tests such as stereoacuity, strabismus,...

OCTA optic disc measurement differences between glaucoma and pituitary macroadenoma

This prospective case-control study aimed to assess the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in distinguishing between glaucoma and pituitary macroadenoma based on optic disc appearance. Thirty-one patients (23 with glaucoma, eight with pituitary macroadenoma) were...

Transsynaptic retrograde degeneration linked to homonymous visual field loss after stroke

centre, of individuals identified with homonymous visual field loss post ischaemic stroke. Exclusion criteria were bilateral ischaemia, anterior / pregeniculate visual pathway affected and other pathology with the potential to effect visual fields. The following were extracted from the medical...

TAC testing in dementia

The aim was to assess the visual acuity measurements performed by the preferential looking method using Teller acuity cards (TAC) in elderly subjects with dementia due to probable Alzheimer’s disease. The mean age was 78.2±9.11 years for patients and 77.2±6.19...

Testing near or distance visual acuity for change during amblyopia therapy

In this study, the authors aimed to determine if any differences occurred between near and distance visual acuity (VA) in a cohort of childhood untreated amblyopia. They recruited 54 patients with mean age 4.9 years, SD 0.44. Mean VA in...

Anti-myelin oligodendrocyte glycoprotein antibody positive optic neuritis: a retrospective medical records review

Optic neuritis causes acute loss of visual function and can result in devastating visual dysfunction. Recently, measurements of anti-aquaporin 4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG) antibodies have become available, making it possible to evaluate the disease pathogenesis. This paper...

MPH treatment effect in ADHD on choroidal vascular index

In this study the authors aimed to investigate the choroidal vascular index (CVI) in treatment-free children with ADHD, children regularly taking methylphenidate (MPH) and healthy controls. This was a prospective cross-sectional study of 52 patients with newly diagnosed ADHD, 46...
