estimated to account for 6 % – 18 % of childhood blindness. 5 In South Africa, ROP accounted for 10.6 % of cases of blindness in schools of the blind in 1995. 6 An estimated 16 000 infants are at risk of ROP in South Africa. 1 Background: Timeous screening of retinopathy of prematurity (ROP) is an important predictor of ROP screening outcomes, and hospitals at different levels of care might have different access to ROP screening by ophthalmologists, resulting in different ROP screening outcomes. Objective: To compare ROP screening outcomes between premature babies from a neonatal facility at a central hospital to those from regional hospitals in Johannesburg. Setting: Retinopathy of prematurity screening in babies born at central and non-central hospitals in Johannesburg, South Africa, between 01 January 2015 and 31 June 2020. Methods: A cross-sectional study describing clinical findings in babies referred for ROP screening at a central Johannesburg hospital. Results: A total of 2035 ROP screening records were included in the study. The babies screened from the central hospital and regional hospitals were 1081 (53.1 % ) and 954 (46.9 % ), respectively. The proportion of babies with ROP were 125 (11.6 % ) and 121 (12.7 % ) in the central hospital and regional hospitals, respectively, and this difference was not statistically significant, p = 0.435. There was a significant association between gestational age (GA) categories and birth weight (BW) with the hospital of birth, with proportionately more babies with GA < 28 weeks, 212 (19.6 % ) versus 158 (16.6 % ) p < 0.001, and BW < 1500 g, 894 (82.7 % ) versus 737 (77.3 % ) p = 0.001, being referred by the central hospital compared to regional hospitals. Conclusion: The prevalence of ROP in regional hospitals does not seem to differ from that found in central hospitals.

Background: Public eye care services in South Africa are relatively underdeveloped. This is, in part, due to optometry services historically being private sector-focussed, as well as a lack of ophthalmologists in the country. Optometry students who engage in service learning at public health facilities are well placed to share their perceptions of this service.Aim: To investigate the perceptions and experiences of optometry students regarding public eye care services in South Africa.Setting: Data were collected on the Phelophepa Health Care Train while it was stationed at Musina and Polokwane in 2019.Methods: A qualitative study was conducted using focus group interviews to collect data from South African optometry students. Two focus group sessions were held, with a total sample of 18 representing two different higher education institutions. Interview recordings were transcribed, and data were thematically analysed using interpretive content analysis.Results: Three main themes emerged, namely ‘inability to deliver quality services’, ‘negative perceptions about public eye care services’ and ‘potential to improve public eye care services’. Strengthening infrastructure and human resource capacity were seen as fundamental steps to improving public eye care services in South Africa.Conclusion: Strengthening public eye care services in South Africa is necessary in order to improve the experience-based perceptions of optometry students towards this sector. Addressing eye health system weaknesses through appropriate resourcing will likely contribute to attracting this potential future human resource to the sector, and assist in alleviating the shortage of human resources for eye health within South Africa’s public health service.Contribution: Optometry education and professional practice in South Africa is increasingly adopting a more public health approach. This shift towards strengthening public eye care services and improving human resources capacity for the same is both important and necessary to address unmet eye health needs in the country. However, current gaps and challenges within the public health system may deter new graduates in South Africa from choosing this practice path if the overall challenges of resourcing and capacity to deliver quality services are not addressed.

Background: Ectopia lentis in children is rare and often associated with systemic conditions. Left untreated, it can lead to visually debilitating complications. Although there are various techniques available, no current consensus for treatment of paediatric ectopia lentis exists.Aim: To describe the management and visual outcomes of paediatric ectopia lentis in an academic referral hospital.Setting: This study was conducted at Cipto Mangunkusumo National Central General Hospital, Jakarta, Indonesia.Methods: A retrospective review was conducted on the medical records of all paediatric ectopia lentis patients treated at our hospital, from 2011 to 2020. Primary outcomes include uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), treatment, surgical technique, selection of intraocular lens (IOL), and postoperative complications.Results: This study included 66 eyes of 39 patients. Average age at initial presentation was 7.8 (2–17) years. Aetiology was mostly non-traumatic, whilst four were secondary to trauma. All eyes except one underwent surgery, and IOLs were inserted in 57.4% of the non-traumatic cohort, with iris-claw IOL as the most popular choice (85.7%). Uncorrected visual acuity and BCVA significantly improved in pseudophakic and aphakic groups (p 0.05). Nearly 60% achieved a BCVA of 6/12 or greater, and the proportion was higher amongst pseudophakic group. Ten eyes had post-operative complications, with a median onset of 393 (1–1095) days after surgery.Conclusion: With varied techniques used to manage paediatric ectopia lentis, the choice of technique was dependent on individual patient condition and surgeon preference. Whilst the proportion of eyes with BCVA of ≥ 6/12 was higher amongst the pseudophakic eyes than aphakic eyes, IOL implantation entails the risk of complications, whereas no complications occurred in those left aphakic. Therefore, no particular technique can be considered marginally superior to the other, and larger studies are needed.
