RESUMO
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. RESULTS: A total of 164 cases were reviewed, 52.4% of them were boys. Median age at presentation was 48 months while the median age at detection was 13.5 months. Seventy-four (45.1%) children had congenital cataract, 31.1% had developmental cataract, and 21.3% had traumatic cataract. The child's mother detected the cataract in 116 (70.7%) of the patients. Median age at presentation for patients with congenital cataract was 18 months and 84 months for developmental cataract. The median age at presentation for congenital cataracts that were noticed by the mother was 17 months compared with 72 months for those noticed by other caregivers (p = 0.0085). The median age at presentation for developmental cataracts that were noticed by the mother was 72 months compared with 114 months for those noticed by other caregivers (p = 0.0065). Gender of the child did not significantly influence the age at detection or presentation. The source of referral and the location of domicile did not significantly affect the time interval between detection of the cataract and presentation to hospital. CONCLUSION: The average age of children presenting with cataracts in our setting is older than in high income countries. Detection of the cataract by the mother increases the likelihood of early presentation; thus, focused maternal education may promote earlier detection and presentation.

Delleman syndrome is a rare congenital disorder. We report an 8-month old female with a history of a fleshy mass covering the left eye since birth. Examination revealed poor vision in the left eye, an upper lid coloboma and an epibulbar dermoid with a large area of alopecia and scalp hypoplasia involving the left frontoparietal region. Transfontanelle ultrasound scan did not reveal any intracranial cyst. Cranial computerised tomography subsequently revealed characteristic cerebral malformations of Delleman syndrome. This report demonstrates clinical and computed tomographic features of a case of Delleman syndrome with emphasis on the usefulness of transfontanelle ultrasonography in assessing for life-threatening intracerebral cysts or hydrocephalus, particularly in resource-limited settings, where neuroimaging is not readily available or affordable.

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. All participants had Icare tonometry and Goldmann applanation tonometry (GAT) performed on them in sequence within a 15-min period. After the measurements, participants were asked to report their assessment of the level of comfort with each method and to state their preferred choice for IOP measurement. One hundred subjects participated in the study; 45 (45 %) were males, and the mean age was 47.1 (± 17.4) years. Forty-three subjects (43 %) reported that Icare was either much more comfortable or more comfortable than GAT, while 31 (31 %) stated that Goldmann applanation was either much more or more comfortable. Twenty-six participants (26 %) reported that the level of comfort was the same with the two instruments. With regard to which of the instruments will be preferred for IOP check at another clinic visit, 53 (53 %) of the respondents preferred the Goldmann applanation tonometer. Some of the participants preferred GAT because they believed it was more sophisticated, while the main reported reason for preferring Icare was the stinging sensation of the anesthetic eye drop when using GAT. Although more participants reported the Icare tonometer to be more comfortable, the Goldmann tonometer was preferred by majority of the respondents.

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. Information about functional vision was obtained using the Pediatric Eye Questionnaire (PedEyeQ). Data obtained from the PedEyeQ were entered into a Rasch-calibrated PedEyeQ Excel response data sheet. Data analysis was done using Statistical Package for Social Sciences (SPSS) software version 22 (SPSS, Inc). RESULTS: A total of 196 pseudophakic children were recruited. Their ages ranged from 2 to 16 years with a mean of 9.8 ± 3.4 years and there was a male-to-female ratio of 2.2:1. The median functional vision score of pseudophakic children across all age groups was 90.0. The functional vision scores were associated with the laterality of cataract, type of cataract, presence of comorbidities, visual acuity (distance and near) in the better eye, and number of surgeries. CONCLUSIONS: The functional vision scores of pseudophakic children were low. Significant predictors of low functional vision scores include surgery for congenital cataract, low average family income, longer duration of time between surgery and recruitment into the study, and poorer best corrected visual acuity in the better eye. The routine assessment of functional vision should be considered an important aspect of pseudophakic children's eye care with a view toward optimizing psychological and social well-being.

RESUMO
OBJECTIVE: To describe the practice patterns for the management of paediatric cataracts among ophthalmologists practising in Nigeria. METHODS: A cross-sectional study of fully trained Nigerian ophthalmologists who perform cataract surgery in children aged 16 years and below. An online questionnaire was distributed via e-mail and social media platforms to respondents. Data on socio-demographic characteristics, type, location and years of practice, status and preferred approach to management of childhood cataracts were obtained and analysed. RESULTS: A total of 41 ophthalmologists responded that they perform paediatric cataract surgery. Of these, 25 (61.0%) were paediatric ophthalmologists while 7 (17.0%) were general ophthalmologists. Most respondents (92.7%) practise in urban settings and 30 (73.2%) work in tertiary hospitals. Most respondents (90.2%) routinely insert intraocular lenses (IOLs) in children aged 2 years and above while 32 (78.0%) routinely under-correct the IOL power. Thirty-four (82.9%) have an anterior vitrectomy machine, 31 (75.6%) routinely perform posterior capsulotomy and anterior vitrectomy, and 17 (58.5%) routinely perform same-day sequential bilateral cataract surgery. Twenty-six (63.4%) respondents routinely give near correction in aphakic children, while 24 (58.5%) respondents routinely give bifocals in pseudophakic children. Compared to other sub-specialists, paediatric ophthalmologists were 24 times more likely to routinely under-correct IOL power (p = 0.001) and 4 times more likely to routinely correct near vision in aphakic children (0.036) as well as prescribe bifocals for pseudophakic children respectively (0.029). CONCLUSION: The practice of paediatric cataract surgery in Nigeria is mainly in line with expected standards, but there is a need for the development of detailed practice guidelines.
RESUMO
PURPOSE: To determine the pattern, causes and risk factors for ocular injuries amongst children presenting to a tertiary facility in Ibadan, southwest Nigeria METHODS: A retrospective review of clinical records of patients aged 16 years and below who presented with ocular injuries to the eye emergency unit between May 2010 and April 2016. Information extracted includes patient's demography, location and circumstances of injury, clinical findings, and management. Data was analysed using IBM SPSS Statistics for Windows, Version 26.0. Descriptive and inferential statistics were calculated. Odds ratio were derived from regression models adjusted for confounders. Significance was set at a P-value of 0.05. RESULTS: A total of 109 children were studied. Majority were boys (male to female ratio=2.9:1). The median age at presentation was 9 years. Injury occurred at home in 67 (61.5%) children, and at school in 30 (27.5%). More than half of the children were injured during play, 18 (16.5%) during corporal punishment, and 34 (31.2%) by accidents during domestic/schoolwork. Majority (73.4%) were closed globe injuries. The odds of injury with sharp objects and ocular trauma score of 4 or less was were 3.2 times (95% Confidence interval {CI}: 1.3-7.7) and 3.9 times (95% CI:1.4-11.4) higher in children aged 0-5 years respectively. The odds of open globe injury was 9.8 times (95% CI: 3.4-28.6) higher in injury from sharp objects. Wood/stick, cane, stone, broomstick and fist/palm/finger were the agents responsible for two-thirds of injuries. CONCLUSION: This study revealed that children predominantly sustain ocular injuries at home and younger children have greater odds of severe injuries with profound implications for visual disability. Health education, adult supervision and the application of appropriate measures necessary for reducing the incidence and severity of childhood ocular trauma are advocated.

PURPOSE: The aim of this study is to describe the clinical profile, pedigree charting, and management of children with familial cataracts at a child eye health tertiary facility in southwest Nigeria. METHODS: The clinical records of children ≤16 years diagnosed with familial cataracts at the Pediatric Ophthalmology Clinic, University College Hospital Ibadan (Ibadan, Nigeria) from January 1, 2015, to December 31, 2019, were retrospectively reviewed. Information on demographic data, family history, visual acuity, mean refractive error (spherical equivalent), and surgical management was retrieved. RESULTS: The study included 38 participants with familial cataract. The mean age at presentation was 6.30 ± 3.68 years, with a range of 7 months to 13 years. Twenty-five patients (65.8%) were male. All patients had bilateral involvement. The mean duration from onset of symptoms to presentation at the hospital was 3.71 ± 3.20 years, with a range of 3 months to 13 years. In 16 of the 17 pedigree charts obtained, at least one individual was affected in each generation. The most common cataract morphology was cerulean cataract, observed in 21 eyes (27.6%). The most common ocular comorbidity was nystagmus which was observed in seven patients (18.4%). Sixty-seven eyes of 35 children underwent surgery within the period of the study. The proportion of eyes that had best-corrected visual acuity ≥6 / 18 before surgery was 9.1%; this proportion had increased to 52.7% at the last postoperative visit. CONCLUSIONS: Autosomal dominant inheritance appears to be the major pattern among our patients with familial cataract. The most common morphological type found in this cohort was cerulean cataract. Genetic testing and counseling services are vital for the management of families with childhood cataract.

OBJECTIVE: To determine the frequency, demography, aetiology and mechanisms of ocular injuries associated with childhood traumatic cataract in Nigeria. METHODS: A retrospective multicentre study conducted across ten child eye health tertiary facilities in Nigeria between January 2017 and December 2021. Clinic records of all children aged 0-17 years who had been diagnosed with cataract at the various participating centres were reviewed. Information collected include: biodata, mechanism of injury; laterality, place of injury; object responsible; person responsible; duration before presentation and surgical intervention. RESULTS: A total of 636 out of 1656 children (38.4%) had traumatic cataracts during the study period. Their mean age was 109.4 ± 45.2 months with a male-to-female ratio of 2:1. Most injuries were unilateral, two (0.3%) children had bilateral involvement. Only 78 (15.3%) children presented within 4 weeks of the injury. Closed globe injuries were responsible for the traumatic cataract in 475 (74.7%) children, while open globe injuries were more likely to present within 24 h (P < 0.001). The commonest objects of injury were cane, sticks, plant, wood and play materials. Self-inflicted injuries occurred in about 82 (13%) children while 407 (64.0%) were caused by close relatives and contacts. The location where trauma occurred was home in 375 (59.8%) and school in 107 (16.8%) children. CONCLUSION: This multicentre study demonstrates that more than one-third of all childhood cataracts in Nigeria are trauma-related and majority are due to closed globe injuries. Public health interventions to reduce the occurrence of ocular trauma and to encourage early presentation after trauma are advocated.
RESUMO
BACKGROUND: Low vision is an important public health problem; however, very few low vision clinics are available to address the needs of low vision patients in most developing countries. The purpose of this study was to describe the characteristics of patients attending the low vision clinic of a Nigerian tertiary hospital. METHODS: This was a prospective cross sectional study of all new patients seen at the low vision clinic over a 36 month period. Patients were administered with a structured questionnaire, and were examined and tested with low vision devices by the attending low vision specialist. Information on the demographic and clinical characteristics of the patients was recorded. RESULTS: A total of 193 new patients seen during the period were studied. The mean age was 41.4 years, and their ages ranged between 6 and 90 years with a male to female ratio of 1.9:1. Majority (58%) were aged below 50 years, 23.3% were children (≤ 15 years), while 21.8% were elderly patients (≥ 65 years). The commonest cause of low vision was retinitis pigmentosa (16.6%); 14.5% had age related macular degeneration (ARMD); 9.8% had albinism; while only 1% had diabetic retinopathy. ARMD (45.2%) was the commonest cause in the elderly patients, while albinism (24.4%) and optic atrophy (24.4%) were the commonest in children. CONCLUSION: The demographic and clinical characteristics of low vision patients seen in this clinic are similar to that of patients in other developing countries, but different from those in developed countries. Elderly patients and females may be under-utilising low vision services. There is a need for further research into the determinants of low vision service utilisation in developing countries. This would further aid the planning and delivery of services to low vision patients in these countries.

To compare the efficacy of 5-fluorouracil (5-FU) with mitomycin C (MMC) in preventing pterygium recurrence when used as an adjuvant following pterygium excision with conjunctival autograft. Low-dose MMC combined with conjunctival autograft is an effective treatment for preventing recurrence following pterygium excision, but safety, cost, and availability limit its use in developing countries. There is a paucity of data on the efficacy of 5-FU when used in Africa as an adjuvant to conjunctival autograft following pterygium excision. This is a randomized controlled prospective trial using either 50 mg/ml 5-FU or 0.01% MMC. Eighty eyes of 80 subjects were studied. Forty-six subjects with a mean age 49.8 ± 13.8 years were treated with 5-FU (USD 13.0 per unit), while 34 patients with a mean age 51.9 ± 12.1 years were treated with MMC (USD 20.0 per unit). There was no significant difference in mean age between the two groups (p = 0.48). The ratio of male to female patients in both groups was similar at 0.92:1 for the 5-FU group and 1:1 for the MMC group (p = 0.85). Mean follow-up period was 35.2 ± 29.1 weeks. Recurrence rate in the 5-FU group was 8.7% compared to 11.8% in the MMC group (recurrence risk ratio = 0.71, 95% CI 0.17-3.1, p = 0.7). One patient from the MMC-treated group had corneoscleral melting. Other complications were mild and not sight threatening. In the prevention of pterygium recurrence, 5-FU appears to compare favorably with low-dose MMC when used as an adjuvant following pterygium excision and conjunctival autograft. Further studies are required to assess the long-term effect of using 5-FU in such cases.

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. Results: Thirty-six (39.1%) out of 92 patients who had squint surgery during the study period met study inclusion criteria. Mean age was 20.5 ± 13.6 years. All patients were administered Maxitrol® ointment postoperatively. Baseline, peak and net change in IOP were 12.9 ± 2.6 mmHg, 21.3 ± 6.8 mmHg and 8.39 ± 7.2 mmHg respectively. Thirty-one (86.1%) patients had elevation in IOP from baseline; 21 (67.7%) of these had significant IOP elevation. Topical steroid therapy was tailed off rapidly for all patients with significant IOP elevation. Twelve patients were commenced on topical IOP lowering medications, with normalization of intraocular pressure in majority of them by three months after surgery. Conclusion: Elevated intraocular pressure with the use of topical dexamethasone ointment after squint surgery was common in this study and majority of the patients had significant elevation in intraocular pressure. Close monitoring of the intraocular pressure of black patients, especially children, on topical steroid medication after squint surgery is strongly recommended.
RESUMO
PURPOSE: The aim of the study was to determine the prevalence and causes of ocular disorders among preschool children. METHODS: A multi-stage random sampling technique was used to select 560 children from a total of 9944 children aged 3-5 years attending nursery schools in the study area. Demographic and other relevant data were collected from the children. They underwent full ophthalmic evaluation including anterior and posterior segment examination as well as cycloplegic autorefraction. RESULTS: Out of the 560 children screened, 170 (30.3%) were 3 years old, 183 (32.7%) were 4 years old, while the remaining 207 (37.0%) were 5 years old. Male-to-female ratio was 1:1.1. Visual acuity was testable using Lea symbol chart in 90% of the children. Ocular disorders were found in 61 eyes of 35 children giving a prevalence of 6.3%. The most common ocular disorder among participants was refractive error (3.9%), followed by allergic conjunctivitis (1.3%). Other identified ocular disorders were strabismus (0.9%), congenital cataract (0.4%), congenital ptosis (0.4%), optic atrophy (0.4%), ectopia lentis (0.2%), and phthisis bulbi (0.2%). There was no statistically significant difference in the distribution of ocular disorders by age or gender. CONCLUSION: Screening is useful in early detection and treatment of ocular disorders in preschool children. Uncorrected refractive error which was identified as the major ocular disorder in these children is treatable. Periodic preschool vision screening would reduce the burden of uncorrected refractive error and other ocular disorders which can interfere with the learning skills of young children entering school.

PURPOSE: To describe the clinical features of patients younger than 16 years with aniridia presenting to the Paediatric Ophthalmology unit of the Eye Clinic, University College Hospital, Ibadan, Nigeria. METHODS: The is a retrospective review of children with aniridia seen between May 2015 and April 2019 at the Paediatric Ophthalmology unit of the Eye Clinic, University College Hospital in Ibadan. Data on demographic characteristics, presenting complaints, ocular and systemic examination findings, and interventions were collected and descriptively summarised. RESULTS: A total of 28 eyes of 14 patients were studied. The mean age was 6.37 ± 4.98 years. Seven (50%) patients were male. Aniridia was diagnosed in first-degree relatives of nine patients. The most common complaint at presentation was poor vision in 11 (78.6%) patients. Objective visual acuity assessment was obtained in 22 (78.6%) eyes. Presenting visual acuity was worse than 20/60 in all 22 eyes and worse than 20/400 in 8 (36.4%) eyes. Refraction was performed in 17 (60.7%) eyes and revealed a mean spherical equivalent of -3.93 ± 5.99 diopters. Twenty (71.4%) eyes had corneal opacities, and lenticular opacities were seen in 15 (62.5%) of 24 eyes. Mean intraocular pressure (IOP) at presentation was 21.62 ± 10.4 mmHg; 12 (41.4%) eyes had elevated IOP at presentation. Ten (35.7%) eyes had cataract surgery and six (21.4%) eyes had glaucoma surgery. CONCLUSION: Familial aniridia was common in this study, and most of the patients presented with moderate to severe visual impairment. The common ocular associations were refractive error, cataract, corneal opacity and glaucoma.
RESUMO
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. Data were analyzed using IBM SPSS Statistics 20.0. RESULTS: Traumatic cataract accounted for 87 (14.7%) of 593 eyes operated for childhood cataract during the period. Of these, a total of 79 records were available for review. There were 56 (70.9%) males with a mean age of 10.11 (±3.39) years. All injuries were unilateral; closed globe injuries accounted for 70 (88.8%) of the cataracts and the left eye was affected in 42 (53.2%) patients. Fifty-two (67.09%) eyes had other ocular injuries apart from cataracts. The morphology of the cataract was membranous in 44 (55.7%) eyes, and 76 (96.2%) eyes had cataract surgery with intraocular lens (IOL) implantation; 39 (51.3%) of these IOLs were implanted within the capsular bag. The preoperative best corrected visual acuity was worse than 6/18 in all 79 (100%) eyes and improved to 6/18 or better in 32 (40.5%) eyes at 3 months postoperatively. CONCLUSION: Traumatic cataract accounted for less than a quarter of all childhood cataracts in our center. Majority of the eyes had successful IOLs implantation during surgery, and the best corrected visual acuity improved in a moderate proportion of these patients.
RESUMO
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. RESULTS: Of the 1240 children who presented to the clinic within the study period, 142 (11.5%) needed surgical interventions. Their ages ranged from 1 month to 16 years, with a mean age of 6.4 ± 4.7 years. Seventy-nine (55.6%) of these were males. The most common indications for surgery were cataract and cataract-related indications (n = 122, 85.9%), followed by glaucoma and strabismus. Other less common indications for surgery were nasolacrimal duct obstruction and epibulbar dermoid. CONCLUSION: Paediatric cataract, the leading cause of childhood blindness in this environment, presents the greatest surgical burden in our unit. It should, therefore, be a major focus of personnel training and equipment procurement for paediatric ophthalmology services in our environment.

BACKGROUND: The Consortium for Advanced Research Training in Africa (CARTA) aims to transform higher education in Africa. One of its main thrusts is supporting promising university faculty (fellows) to obtain high quality doctoral training. CARTA offers fellows robust support which includes funding of their attendance at Joint Advanced Seminars (JASes) throughout the doctoral training period. An evaluation is critical in improving program outcomes. In this study; we, CARTA fellows who attended the fourth JAS in 2018, appraised the CARTA program from our perspective, specifically focusing on the organization of the program and its influence on the fellows' individual and institutional development. METHODS: Exploratory Qualitative Study Design was used and data was obtained from three focus group discussions among the fellows in March 2018. The data were analyzed using thematic approach within the framework of good practice elements in doctoral training-Formal Research Training, Activities Driven by Doctoral Candidates, Career Development as well as Concepts and Structures. RESULTS: In all, 21 fellows from six African countries participated and all had been in the CARTA program for at least three years. The fellowship has increased fellows research skills and expanded our research capacities. This tremendously improved the quality of our doctoral research and it was also evident in our research outputs, including the number of peer-reviewed publications. The CARTA experience inculcated a multidisciplinary approach to our research and enabled significant improvement in our organizational, teaching, and leadership skills. All these were achieved through the well-organized structures of CARTA and these have transformed us to change agents who are already taking on research and administrative responsibilities in our various home institutions. Unfortunately, during the long break between the second and the third JAS, there was a gap in communication between CARTA and her fellows, which resulted in some transient loss of focus by a few fellows. CONCLUSION: The CARTA model which builds the research capacity of doctoral fellows through robust support, including intermittent strategic Joint Advanced Seminars has had effective and transformative impacts on our doctoral odyssey. However, there is a need to maintain the momentum through continuous communication between CARTA and the fellows all through this journey.

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. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential.
