However, anecdotal evidence suggests that many children across world are diagnosed late. To our knowledge, clinical presentation retinoblastoma has never been assessed on global scale. report stage at in patients during single year, to investigate associations between variables national income level, risk factors for advanced disease diagnosis.

BackgroundRetinoblastoma is the most common intraocular cancer worldwide. There some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these have not been assessed on a global scale. We aimed report 3-year globally and investigate factors associated survival.MethodsWe did prospective cluster-based analysis of treatment-naive patients who were diagnosed between Jan 1, 2017, Dec 31, then treated followed up 3...
Purpose: To introduce and assess the results of a long-term follow-up one-snip punctoplasty with monocanalicular stent (Mini Monoka) for acquired external punctal stenosis (AEPS) without associated internal canalicular stenosis. Design: Prospective non-comparative interventional case series. Methods: Thirty-five eligible patients (53 eyes) AEPS underwent horizontal Mini Monoka tube insertion by or under supervision consultant Oculoplastic surgeon from June 1999 to May 2002. Diagnostic...
The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, most common childhood eye cancer.

Background: The relationship between lag time and outcomes in retinoblastoma (RB) is unclear. In this study, we aimed to study the effect of onset symptoms diagnosis countries based on their national-income analyse its outcomes. Methods: We performed a prospective 692 patients from 11 RB centres 10 1 January 2019 31 December 2019. Results: following factors were significantly different among level: age at (p = 0.001), distance home nearest primary healthcare centre 0.03) mean detection first...
To investigate in a large global sample of patients with retinoblastoma whether sex predilection exists for this childhood eye cancer.A cross-sectional analysis including 4351 treatment-naive from 153 countries who presented to 278 treatment centers across the world 2017. The ratio (male/female) was compared at birth by means two-sided proportions test level, country economic grouping, continent, and selected countries.For entire sample, mean ratio, 1.20, higher than weighted birth, 1.07 (p...

Smoking is associated with common sight-threatening eye conditions. We suspected that this link was little known and it might be a potent novel health promotional tool. therefore developed programme ultimately aiming to reduce the burden of disease attributable smoking. The aims were (1) raise awareness between smoking advocate changes in relevant policies (2) investigate promote change professional practice so smokers are identified routinely offered cessation advice/support eyecare...
Background Rates of care abandonment for retinoblastoma (RB) demonstrate significant geographical variation; however, other variables that place a patient at risk abandoning remain unclear. This study aims to identify the factors across multinational set patients. Methods A prospective, observational 692 patients from 11 RB centres in 10 countries was conducted 1 January 2019 31 December 2019. Multivariate logistic regression used associated with higher rates abandonment. Results Logistic...
