Several epidemics of blindness due to retinopathy of prematurity (ROP) have been described, with the most recent (the third) occurring in middle income countries in Latin America and Eastern Europe initially, and more recently in the more advanced economies in Asia. In these settings, which are characterized by variation in the quality of neonatal care and inadequate coverage of ROP screening and treatment, larger, more mature infants are affected as well as extremely preterm infants. In 2010 the annual incidence of blindness and visual impairment from ROP globally was estimated to be 32,300, with the lowest incidence in sub-Saharan countries. However, ROP is likely to become an increasingly important cause of blindness in children in sub-Saharan Africa as neonatal care expands unless policies and programmes for control are included at the outset.
IntroductionIncreased survival of preterm babies in sub-saharan Africa has held to an increasing prevalence of Retinopathy of prematurity (ROP). This study was done to determine the ROP prevalence in a hospital with advanced neonatal care in urban Kenya.MethodsA hospital-based retrospective review of the records of premature infants screened for ROP between January 2010 and December 2015. Records of all premature infants screened for ROP in the neonatal unit and outpatient eye clinic were extracted. Information on Birth weights, Gestational age, Maternal risk factors (mode of delivery, pre-eclampsia/eclampsia) and Neonatal risk factors (neonatal sepsis, days on oxygen, blood transfusion) was recorded in a questionnaire then analysed.Results103 infants were included in the study. Mean gestational age was 29.9 ± 2.2 weeks and the mean birth weight was 1280.1 ± 333.0 grams. Forty-three infants were diagnosed with ROP, a prevalence of 41.7%. Majority of these had Stage 1 or 2 ROP in Zone II, which spontaneously regressed with follow up. Nine infants were diagnosed with vision-threatening ROP (any Zone I disease or Stage 2/3 disease in Zone II with plus disease), a prevalence of 20.9%. All of these underwent laser treatment in the neonatal unit. The most significant risk factor was low gestational age. Other risk factors identified were: low birth weight and blood transfusions.ConclusionROP prevalence in sub-saharan Africa will match those in middle-income and high income countries in neonatal units with advanced care and low mortality.
Purpose: To audit phacoemulsification cataract surgeries performed independently after a short - term training completed in a rural hospital in Kenya, and to benchmark the outcomes against WHO recommendations. Methods: This retrospective case-series study recruited patients who had had phacoemulsification cataract surgery at Sabatia Eye Hospital from January to December 2018. All the surgeries were performed by a single surgeon following a brief training in the same center. Data were collected retrospectively using a detailed questionnaire. Results: Of the one hundred and twenty eyes operated on during this period, one-hundred and sixteen eyes of 86 patients met the inclusion criteria. The mean age was 62 years and the majority of the eyes (83.6%) had vision less than 6/18 preoperatively. Co-morbidities included diabetic retinopathy (3.4%), age-related macular degeneration (2.6%), trauma (1.7%) and glaucoma (0.9%). Surgical complications were not severe enough to affect the final best-corrected visual acuity, unlike the comorbidities that were negatively correlated with visual outcomes (p-value< 0.001). Good outcomes were 81% against a WHO target of 80% for uncorrected visual acuity category, and 96.6% in the best-corrected visual acuity category against a target of 90%. The Royal College of Ophthalmology database of cataract surgery outcomes and the European Registry of Quality Outcomes for cataract and refractive surgery had comparable results. Conclusions: This local training model was based on apprenticeship and skills transfer. It can achieve high-quality visual outcomes meeting WHO recommendations.
Irreversible visual loss due to retinal toxicity is one of the side effects of hydroxychloroquine (HCQ) therapy. The recent outbreak of the novel coronavirus-19 (COVID 19) has seen HCQ proposed as a possible treatment and prophylactic drug, leading to its increased use. Many are unaware of its ocular side effects. We describe a case of HCQ-induced retinopathy in a 46-year-old female who was referred by a rheumatologist for routine eye review.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
