This study evaluated outcomes in children aged less than eight years with corneal laceration and traumatic cataract who had cataract extraction one to eight weeks after primary corneal wound repair. This was a retrospective study of 47 eyes of 47...

Albinism and later life visual development

This study aimed to evaluate whether best corrected visual acuity changed significantly in the second decade of life in those with albinism and the impact of extraocular muscle surgery and type of albinism on change in acuity during the second...

Childhood blindness and visual impairment in the Narayani Zone of Nepal

Up to 50% of childhood blindness is preventable or treatable, and its control is a high priority in the VISION 2020 initiative of the International Agency for the Prevention of Blindness. In this study, the authors utilised the rapid assessment...

A novel presentation of optic disc oedema with syphilis

Optic disc oedema (ODE) due to syphilis without visual compromise has been primarily attributed to papilloedema from raised intracranial pressure or optic perineuritis from optic nerve sheath inflammation. These terms were proposed before magnetic resonance imaging (MRI) was largely available....

Visual retraining for homonymous hemianopia following stroke

This is a clinical trial evaluating the efficacy of motion discrimination training as a potential therapy for stroke-induced hemianopic visual field defects involving 48 patients. They were randomised into two arms, one intervention (deficit-field) and one control (sighted-field). Patients were...

Comparison of two visual acuity test versions for different distances in a paediatric population

The authors present the findings of a study which aimed to determine whether using 2 metre and 4 metre retro-illuminated ETDRS charts are comparable in children. Order of testing was standardised (right eye, left eye, binocular), however different charts were...

A retrospective medical notes review in patients with poor vision due to NAION

Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...
