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...

CVI features in an Indian population

This study describes the predisposing factors and ophthalmic characteristics of children with cortical visual impairment (CVI) at a tertiary centre in India. This was a retrospective cross-section study of children <16-years-old over a four-year period. A review of 88 patients...

OCT angiography findings in amblyopic eyes

In this study, optical coherence tomography angiography (OCTA) was used to detect the existence of any vascular dysfunction in superficial and deep retinal layers that accompany visual impairment in amblyopic eyes compared to fellow and control eyes. The study included...

Childhood glaucoma outcomes and prognosis

This study aimed to evaluate the relationship between clinical characteristics and visual acuity in childhood glaucoma. The study included 45 eyes of 31 patients; 33.3% with primary childhood glaucoma and 66.7% with secondary glaucoma; 53.4% of secondary cases had glaucoma...

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...

Transient visual loss caused by crowded optic discs

The author presents four cases of transient visual loss (TVL) in young females (age range at presentation 14-22 years) with crowded optic discs. Patient demographics, investigations, medical and social histories are provided for all patients. A review of evidence for...

Visual acuity conversion to digital acuity

The author proposes a basic set of evidence-based digital acuities for alpha vision to facilitate formatting of visual acuity data uniformly. This work was informed by a review of the literature. A full table provides US and international classification of...

Surgery technique for subluxation in Marfan syndrome

The authors evaluated the efficacy and safety of bimanual capsulorrhexis combined with sutureless scleral-fixated IOL implant in children with Marfan syndrome. Seven children (14 eyes) with subluxated lenses underwent bilateral surgery; four female, three male with mean age of 7.1...
