Purpose: To determine the functional vision of pseudophakic children attending a child eye health tertiary facility in southwest Nigeria.
Methods: A hospital-based descriptive study of pseudophakic children attending the Pediatric Ophthalmology outpatient clinic of a tertiary facility in southwest Nigeria was conducted between June and November 2021. Details of demography and clinical examination findings were obtained using a semi-structured questionnaire.
Introduction: ophthalmic genetics is rapidly evolving globally but is still nascent in much of sub-Saharan Africa, with gaps in knowledge about the burden in the region. This study evaluated the burden and manifestations of genetic eye diseases in children in Ibadan, Nigeria.
Methods: this was a hospital-based cross-sectional study in which new and follow-up paediatric eye clinic patients were recruited consecutively at the University College Hospital, Ibadan.
The decision for genetic testing in children is usually taken by their parents or caregivers, and may be influenced by sociocultural and ethical concerns. This study evaluateds the perspectives of Nigerian parents towards genetic testing of their children with genetic eye diseases parental willingness for genetic testing in their children, and its determinants, in a hospital setting in Nigeria. This cross-sectional, hospital-based study was conducted at the Eye clinic, University College Hospital, Ibadan.

Aim And Objectives: The aim was to generate evidence for further planning and monitoring of the on-going eye care program. The objectives included determination of the prevalence of blindness and visual impairment, causes of blindness and visual impairment, and assessment of cataract services and barriers to cataract surgery uptake.
Purpose: To describe the pattern of intraocular pressure (IOP) changes after squint surgery in eyes of black Africans at the University College Hospital, Ibadan, Nigeria.
Materials And Methods: This was a retrospective review of the clinical records of patients who underwent squint surgery between 2010 and 2019. Data on demographic characteristics, preoperative and postoperative intraocular pressure values, co-existing ocular pathology, type of strabismus, surgery performed, frequency and duration of postoperative topical steroid use and treatment received for elevated intraocular pressure were collected and descriptively summarised.
Objective: The objective of this study was to describe the outcome of surgery for traumatic cataract and associated factors in children aged 16 years and below operated in a tertiary facility.
Methods: This was a retrospective review of records of children who had surgery for traumatic cataract between August 2015 and August 2019. Information on biodata, preoperative visual acuity, surgical methods, complications, and postoperative visual acuity were retrieved.
Objectives: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria.

Objective: The objective of the study was to determine the proportion of children requiring ocular surgery amongst new patients presenting to the Paediatric Ophthalmology Unit of the University College Hospital, Ibadan, over a 2-year period, to enhance planning and improve the efficiency of service delivery.
Methods: The study was a retrospective review of records of all new patients aged 0-16 years who presented to the Paediatric Ophthalmology Unit of the University College Hospital, Ibadan, over a 2-year period (May 2015-April 2017). Information on age and gender, clinical diagnosis and indications for surgery and type of surgery scheduled were retrieved from the diagnosis register of the unit, and a descriptive analysis was performed.
Background: To describe factors which influence the age at detection and age at presentation of patients with childhood cataract at a tertiary eye care facility in Southwest Nigeria.
Methods: A retrospective review of children who presented with cataract between 2011 and 2015. Case notes were reviewed and data on age at detection and presentation as well as other clinical information was collected and analyzed using Stata 12 statistical software.
Purpose: To determine the preoperative visual acuity of cataract patients over a 10-year period in a tertiary facility as a means of auditing the cataract surgical services.
Methods: A retrospective study of patients with age-related cataracts who had cataract surgery performed between January 2007 and December 2016 at the University College Hospital, Ibadan. Systematic random sampling and probability proportionate to size were used to recruit a representative sample.
Aim: The aim was to determine the prevalence and pattern of congenital colour vision deficiency among secondary school students in Ibadan, Nigeria.
Subjects And Methods: A descriptive cross-sectional study was conducted among students from three public secondary schools through a multi-staged sampling method. Ocular examination including visual acuity assessment and colour vision test with the Ishihara plate was performed for all students.
The purpose of this study was to compare patient comfort and preference between the use of Icare tonometer and Goldmann applanation tonometer for the measurement of intraocular pressure (IOP). This was a prospective study carried out at the Eye clinic of the University College Hospital, Ibadan on volunteers aged 18 years and above. Demographic information of the participants was collected using a proforma.
