Case reports of neuro-visual consequences of mild COVID-19 in children

Neuro-visual involvement has been reported in numerous patients with severe SARS-CoV-2 disease, mainly among adult patients. In children, such involvement has been reported in rare cases, often in those presenting with severe forms of COVID-19. The aim of this work...

Comparison of visual field indices between normal adults and children

The authors present a prospective observational study which aimed to compare visual field indices with retinal nerve fibre layer (RNFL) thickness using optical coherence tomography (OCT) in normal adults and children. Children aged 6–18 years were recruited from a single...

Development of testing protocols for high and low contrast visual acuity

Dysfunction of the afferent visual system, characterised by impairments in high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA) have been demonstrated in some neurological conditions such as multiple sclerosis and Parkinson’s disease. HCVA and LCVA are also potential quantitative...

Management options for microphthalmia with orbital cyst with / without visual potential

The authors present six cases (seven eyes) of congenital microphthalmia and orbital cyst. These cases were newborn mainly with one aged 20 years. There were four females and two males and two of seven eyes had a visual potential of...

Prognostic factors for visual acuity in patients with LHON after gene therapy

This retrospective study investigates prognostic factors affecting the visual acuity after a single intravitreal injection of rAAV2-ND4 gene therapy in 53 patients with Leber’s hereditary optic neuropathy (LHON) with mutation at site 11 778. Patients were reviewed one and three...

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...

Dementia and visual impairment: what is the relationship and are we providing the best care?

Carla Maden discusses the implications of living with both dementia and visual impairment, and how general medical junior doctors and ophthalmologists can help to alleviate this burden and improve the quality of life of such patients. Dementia and visual impairment...

Children’s visual acuity test without professional supervision

Visual disturbance heralding stroke: are we seeing the signs in time?

Isolated visual symptoms may be an early presenting feature of stroke, and timely recognition of such atypical cases is important because treatment for stroke has a limited time-window of efficacy. Stroke occurs in approximately 150,000 people per year in the...

Macular imagery: observing the visual sensations pre- and post-Jetrea injections

A 63-year-old woman, a professional painter, was diagnosed with vitreomacular traction (VMT) in 2017. She had a history of metamorphopsia, drop in visual acuity (VA) in the left eye (6/6 in the RE; 6/18 in the LE), foveal vitreomacular traction...

Visual field progression after glaucoma drainage device implantation

This retrospective interventional case series assessed changes to visual fields after implantation of a glaucoma drainage device (Baerveldt, Ahmed or Molteno Devices) between 2010 and 2015. A total of 106 eyes from 96 patients were included in the final analysis...

Home testing versus in-person visual acuity test results

This retrospective review compared visual acuity findings by parents / carers during telehealth consultations compared with their subsequent in-person tests. Parents were given an information pack with testing instructions for home tests. The study included 43 patients (86 eyes) with...
