Agreement Between Lea Symbols And Patti Pics Visual Acuity In Children And Adults, Arjun Sapkota, Sanjeeta Sitaula, Gauri Shankar Shrestha, Niraj Dev Joshi, Bipin Koirala, Nabin Paudel

Articles

Patti Pics (PP) and Lea Symbols (LS) are commonly used by eye care practitioners worldwide. Although the relationship between the two tests is fairly well understood, the availability of different chart designs (single optotypes, multiple optotypes, multiple optotypes with crowding box) merits futher understanding. The purpose of this study is to explore the agreement between the acuity measures obtained with Patti Pics and Lea Symbols in children and adults and compare their performance with the Sloan Letter (SL) chart in adults.

The purpose of this study is to explore the agreement between the acuity measures obtained with Patti Pics and Lea Symbols in children and adults and compare their performance with the Sloan Letter (SL) chart in adults. Methods: Monocular visual acuity was obtained from ninety-three 3 to 5-year-old children using Patti Pics and Lea Symbols. Acuities …

Choroidal Thickness Profiles And Associated Factors In Myopic Children, Emmnuel Kobia Acquah, Daniel Ian Flitcroft, Gareth Lingham, Nabin Paudel, James Loughman

Articles

SIGNIFICANCE: This study addresses the lack of choroidal thickness (ChT) profile information available in European children and provides a baseline for further evaluation of longitudinal changes in ChT profiles in myopic children as a potential biomarker for myopia treatment and identifying children at risk of myopic progression.

PURPOSE: This study aimed to investigate ChT profiles and associated factors in myopic children.

METHODS: Baseline data of 250 myopic children aged 6 to 16 years in the Myopia Outcome Study of Atropine in Children clinical trial were analyzed. Choroidal thickness images were obtained using swept-source optical coherence tomography (DRI-OCT Triton Plus; Topcon …

Prevalence Of Ametropia, Amblyopia And Visual Impairment In Schoolchildren In Ireland, Siofra Harrington

Doctoral

Background: Uncorrected refractive error is an avoidable cause of visual impairment (Naidoo et al., 2016). Currently, there is a lack of adequate data on eye and vision disorders in schoolchildren in Ireland. Accurate prevalence estimates of refractive error and vision disorders are necessary to determine their impact on public health and to assess the need for interventions (McCarty and Taylor, 2000). Purpose: This study reports the prevalence of ametropia, presenting visual impairment, amblyopia and provides population norms for ocular biometric measures in schoolchildren in Ireland. Links between refractive error and demographic and lifestyle factors were investigated. The impact of poor …

Comparison Of Amblyopia In Schoolchildren In Ireland And Northern Ireland: A Population-Based Observational Cross-Sectional Analysis Of A Treatable Childhood Visual Deficit, Síofra Harrington, Karen Breslin, Veronica O'Dwyer, Kathryn Saunders

Articles

Objectives This study reports the prevalence of persistent amblyopia (post-traditional treatment age) in schoolchildren in the Republic of Ireland (henceforth Ireland) and Northern Ireland (NI), UK; populations with broadly similar refractive and genetic profiles but different eye-care systems.

Design This is a population-based observational study of amblyopia and refractive error.

Setting Recruitment and testing in primary and post-primary schools in Ireland and NI.

Participants Two groups identified through random cluster sampling to represent the underlying population; Ireland 898 participants (12–13 years old) and NI 723 participants (295 aged 9–10 years old, 428 aged 15–16 years old).

Main outcome measures Monocular …
