PURPOSE To compare visual acuity results obtained using the Lea Symbols chart with visual acuity results obtained with the Bailey-Lovie chart in school-aged children and adults using a within-subjects comparison of monocular acuity results. METHODS Subjects were 62 individuals between 4.5 and 60 years of age, recruited from patients seen in five optometry clinics. Each subject had acuity of t...

Binocular iPad Treatment of Amblyopia for Lasting Improvement of Visual Acuity Repeated experience with dichoptic perceptual learning tasks and dichoptic game play have been shown to be effective in improving the visual acuity of amblyopic children and adults.1-4 However, whether the visual acuity gains achieved with binocular treatment are long lasting has not yet been addressed. We examined t...

BACKGROUND AND OBJECTIVE: Long-chain polyunsaturated fatty acids (LCPUFAs) are hypothesized to affect visual acuity development in infants. Randomized controlled trials (RCTs) have been conducted to assess whether supplementation of LCPUFAs of infant formulas affects infant visual acuity. This meta-analysis was conducted to evaluate whether LCPUFA supplementation of infant formulas improves inf...

ABSTRACT The main purpose of this review is to compare and analyze the results of the main PresbyLASIK approaches; central and peripheral. SUMMARY A comprehensive research was conducted in PUBMED using keywords like "presbyopia correction", "PresbyLASIK", "Corneal multifocality", "Laser blended vision". We reviewed the PresbyLASIK technique, uncorrected distance visual acuity (UDVA), correcte...

PURPOSE The relationship between astigmatic refractive errors and their associated visual acuity has been studied in recent years in the context of refractive power space. The influence of the axis of astigmatism remains a matter of controversy. Our goal in this study is to provide additional experimental evidence to clarify this subject. The influence of the simulated axis orientation was comp...

PURPOSE A retrospective study of the outcome of congenital and developmental cataract surgery was conducted in a public child eye health tertiary facility in children <16 years of age in Southern Nigeria, as part of an evaluation. MATERIALS AND METHOD Manual Small Incision Cataract Surgery with or without anterior vitrectomy was performed. The outcome measures were visual acuity (VA) and chan...

AIMS To examine objective visual acuity measured with ETDRS, retinal thickness (OCT), patient reported outcome and describe levels of glycated hemoglobin and its association with the effects on visual acuity in patients treated with anti-VEGF for visual impairment due to diabetic macular edema (DME) during 12months in a real world setting. METHODS In this cross-sectional study, 58 patients (2...

BACKGROUND The inclusion for rehabilitation of visually impaired children is partly based on the measurement of near vision, but guidelines for near visual acuity assessment are currently lacking. The twofold purpose of this systematic review was to: (i) provide an overview of the impact of the chart design on near visual acuity measured, and (ii) determine the method of choice for near vision ...
