Visual impairment burden in retinopathy of prematurity: trends, inequalities, and improvement gaps.

Retinopathy of prematurity (ROP) is an important cause of avoidable childhood visual impairment, and the increase in number and survival of premature infants may inflate its burden globally. We aimed to comprehensively assess the trends and inequalities in the burden of ROP-related visual impairment and to identify improvement gaps to facilitate appropriate actions in neonatal care systems. We obtained ROP data from the Global Burden of Disease 2019 study. We employed joinpoint regression analysis to assess the trends of the burden of ROP-related visual impairment, measured by age-standardised prevalence rates, health equity analysis methods to evaluate cross-country burden inequalities, and data envelopment and stochastic frontier analyses to identify improvement gaps based on the development status, i.e., sociodemographic index (SDI). Between 1990 and 2019, the age-standardised prevalence rates of ROP-related visual impairment significantly increased worldwide (average annual percentage change: 0.23 [95% confidence interval, 0.21-0.26] among males and 0.26 [0.25-0.27] among females), primarily in developed regions. Although significant SDI-related cross-country inequalities were identified, these reduced over time (slope index of inequality: -57.74 [-66.22 to -49.25] in 1990 to -29.68 [-38.39 to -20.97] in 2019; health concentration index: -0.11 [-0.13 to -0.09] in 1990 to -0.07 [-0.09 to -0.06] in 2019). Notably, some less-developed countries exhibited superior performance despite limited resources, whereas others with a higher SDI delivered lagging performance.  Conclusion: The global burden of ROP-related visual impairment has steadily increased between 1990 and 2019, with disproportionate burden concentration among less-developed countries, requiring appropriate preventive and intervention measures. What is Known: • Retinopathy of prematurity (ROP) is an important cause of avoidable childhood visual impairment. • The prevalence of ROP is anticipated to increase due to the growing number of extremely premature infants. What is New: • The prevalence of ROP-related visual impairment has increased worldwide, primarily in developed regions, with declining but persisting cross-country inequalities. • The increasing burden of ROP-related visual impairment should be considered as part of global and national health agendas, requiring interventions with proven efficacy.

Successful treatment of retinopathy of prematurity in oculocutaneous albinism with OCA2 variants: a case report and review of literature.

BACKGROUND: Oculocutaneous albinism (OCA) is a group of autosomal recessive hereditary disorders that affect melanin biosynthesis, resulting in abnormalities in hair, skin, and eyes. Retinopathy of prematurity (ROP) is a proliferative retinopathy mainly observed in premature infants with low birth weight and early gestational age, but it can also affect full-term infants or children with normal weight, particularly in developing countries. The coexistence of ROP and OCA is rare. There is limited documentation regarding treatment approaches, with few studies reporting positive outcomes with laser treatment due to the absence of melanin pigment. This study discusses the treatment challenges in a female infant diagnosed with ROP and OCA, and underscores the importance of genetic analysis in guiding therapeutic decisions for this rare comorbid condition. CASE PRESENTATION: The study presents a case of ROP occurring concurrently with OCA. Genetic testing revealed two variants, c.727C > T (p.R243C) and c.1832 T > C (p.L611P), in the OCA2 gene, inherited from the patient's mother and father, respectively. The identified mutations were consistent with a diagnosis of OCA2, classified as a subtype of OCA. The patient initially received intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection, followed by laser photocoagulation therapy for a recurrent event. A favorable outcome was observed during the 2-month follow-up period. CONCLUSIONS: The co-occurrence of ROP and OCA is a rare phenomenon, and this is the first recorded case in the Chinese population. The current case supports the use of laser as the primary treatment modality for ROP in OCA2 patients with partial pigmentation impairment. Furthermore, genetic analysis can aid in predicting the effectiveness of laser photocoagulation in this patient population.

Ophthalmic sequelae of prematurity in late childhood and adulthood: A review.

Advances in the care of premature infants have resulted in unprecedented rates of survival of these infants into adulthood, including those born at very low gestational ages. Ophthalmologists have historically followed premature infants to assess for the presence of and potential need for treatment of retinopathy of prematurity. However, a growing body of literature suggests that the ophthalmic consequences of prematurity extended beyond retinopathy of prematurity and that ophthalmic sequelae of prematurity can endure through adulthood even among formerly preterm adults who were never diagnosed with retinopathy of prematurity. These abnormalities can include a range of both anterior segment and posterior segment sequelae, including higher rates of corneal aberrations, ocular hypertension, strabismus, foveal anomalies, and retinal tears and detachments. This review aims to summarise this literature, underscoring the importance of lifelong examinations and regular monitoring for these complications among adults who were born prematurely.

Macular Curvature in Adults Born Preterm With and Without ROP: Results from the Gutenberg Prematurity Eye Study.

Purpose: This study investigated the effects of prematurity and retinopathy of prematurity (ROP) as well as the associations of the ocular geometry with macular curvature in adults. Methods: The Gutenberg Prematurity Eye Study is a retrospective cohort study of preterm and full-term participants aged 18 to 52 years with a prospective ophthalmologic examination. The main outcome measure was the macular curvature in the central foveal optical coherence tomography (OCT) scan and its associations with gestational age (GA), birth weight and birth weight percentile, ROP occurrence, ROP treatment, and other perinatal factors were evaluated in univariable and multivariable linear regression analyses. Furthermore, a second model assessed the association of ocular geometry with macular curvature. Results: In the present study, 550 eyes of 284 adults born preterm and 277 eyes of 139 adults born full-term were examined (aged = 28.7 ± 8.7 years, 240 female subjects). In multivariable analyses for perinatal parameters, ROP treatment (B = -52.44, P = 0.023) and maternal smoking during pregnancy (B = 26.41, P = 0.019) showed an association with macular curvature. Regarding ocular geometric parameters, posterior segment length (B = 9.07, P < 0.001) and subfoveal choroidal thickness (B = -0.26, P < 0.001) were associated with macular curvature, central corneal thickness, anterior chamber depth, lens thickness, and foveal retinal thickness were not associated. Conclusions: Adults treated for ROP had relatively more negative curvature values compared to the full-term group, indicating a macular protrusion toward the vitreous cave. A thicker subfoveal choroidal thickness was associated with a flatter macular curvature, whereas a longer posterior segment length was associated with a steeper macular curvature indicating the characteristics of the myopic elongation of the eye.

Outcomes of Modified Limbal Lensectomy-Vitrectomy in Stages 4B and 5 Retinopathy of Prematurity with Extended Retrolental Fibroplasia.

PURPOSE: To report on the anatomical and functional outcomes of a modified limbal lensectomy-vitrectomy (LV) approach for stages 4B and 5 retinopathy of prematurity (ROP) as defined in the International Classification of Retinopathy of Prematurity, 3rd Edition (ICROP 3). DESIGN: Retrospective, monocentric, consecutive case series. PATIENTS: Infants with ROP that underwent limbal LV for diffuse retrolental fibroplasia. METHODS: Clinical charts and Retcam photographs were reviewed. Surgical approach consisted of a limbal LV through peripheral iridectomies with centripetal dissection of the preretinal fibrosis. MAIN OUTCOME MEASURES: Anatomical success and visual function at last follow-up were evaluated. Multivariate logistic regression was used to explore potential prognostic factors affecting the anatomical outcome. RESULTS: A total of 128 eyes of 81 patients with a mean gestational age of 28.7 ± 3.0 weeks and a mean birthweight of 1244 ± 429 g were included. Eighteen eyes (14.1%) had a stage 4B, 24 (18.8%) a stage 5B, and 86 a stage 5C (67.2%) ROP. Mean age at surgery was 57.4 ± 36.3 weeks and mean postoperative follow-up was 22.7 ± 20.4 months. Only 5 eyes (3.9%) had prior peripheral retinal ablation. Macular reattachment was achieved in 74 eyes (57.8%). Controlling for other baseline factors, a stage 5C (versus stage 4B, odds ratio [OR] = 6.9 [1.5-32.1], P = 0.01 and versus stage 5B, OR = 7.4 [1.5-37.1], P = 0.02), the presence of vascular activity (OR = 6.4 [2.3-18.1], P < 0.001), and the presence of Schlieren sign (OR = 13.0 [2.1-82.2], P = 0.006) were associated with a failure of macular reattachment. Visual acuity was assessed in 92 eyes (71.9%), among which 59 eyes (64.1%) had light perception or better. CONCLUSIONS: Modified limbal LV resulted in macular reattachment in more than half of eyes with ROP-related retinal detachment and diffuse retrolental fibrosis. A stage 5C based on ICROP 3, the presence of vascular activity, and a Schlieren sign were significantly associated with a failure of macular reattachment.

Incidence of Retinopathy of Prematurity in Neonates with Neonatal Sepsis.

BACKGROUND: One of the most important complications of premature birth is retinopathy of prematurity (ROP). Sepsis may increase the incidence of this complication. The aim of this study is to compare the incidence of ROP in neonates with and without sepsis. METHODS: In a retrospective case-control study, preterm infants admitted to the neonatal intensive care unit (NICU) of Ghaem hospital from 2014 to 2022 were examined. The case group consisted of 155 preterm infants with definite sepsis (positive blood culture and clinical signs of sepsis) and the control group included 145 preterm infants without sepsis whose maternal and neonatal characteristics were collected; they were examined by a retinologist and evaluated for ROP at 32 weeks or four weeks after birth. Finally, we used the chi-square and the t test to compare the two groups. RESULTS: Out of 155 preterm infants with sepsis, 70% and out of 145 preterm infants without sepsis, 58% had ROP (P=0.023). Also, low birth weight, low initial Apgar score and low 5-minute Apgar score were significantly associated with ROP (P<0.05). CONCLUSION: Based on the results of this study, sepsis is a serious risk factor for ROP. We can reduce its incidence and complication by preventing sepsis in premature infants.

Successful management of iatrogenic tear in vitrectomy for retinopathy of prematurity-related retinal detachment: a case report / Tratamento bem-sucedido de rotura iatrogênica em vitrectomia para descolamento de retina por retinopatia da prematuridade: relato de caso

ABSTRACT Retinal detachment related to retinopathy of prematurity is a surgical challenge, and vitrectomy can directly release transvitreal traction resulting from fibrous proliferation. The presence of iatrogenic breaks is a poor prognostic factor and has been considered a dismal prognosis. We report a case of premature female baby that underwent a 3-port 23-Gauge pars plana vitrectomy for stage 4A retinopathy of prematurity, with intraoperative progressive rhegmatogenous detachment complication. Lensectomy, extensive membrane dissection and vitreous shaving, followed by a posterior retinotomy, fluid air exchange, extensive peripheral photocoagulation and C3F8 15% injection were performed. Successful anatomical result was obtained.

RESUMO O descolamento de retina relacionado à retinopatia da prematuridade é um desafio cirúrgico, e a vitrectomia é um procedimento capaz de romper diretamente a tração vitreorretiniana resultante da proliferação fibrosa. A presença de roturas iatrogênicas é um fator prognóstico ruim e tem sido considerada como prognóstico sombrio. Relatamos um caso de bebê prematuro do sexo feminino que foi submetido à vitrectomia via pars plana (23 Gauge; três incisões), para retinopatia da prematuridade estágio 4A, complicada por descolamento regmatogênico progressivo intraoperatório. Foram realizadas lensectomia, dissecção extensa da membrana e aspiração vítrea, seguidas de retinotomia posterior, troca fluido-ar, fotocoagulação periférica extensa e injeção de C3F8 a 15%. O resultado anatômico bem-sucedido foi obtido.

Ocular sequelae of retinopathy of prematurity in Manaus, Amazonas / Sequelas oculares estruturais da retinopatia da prematuridade em crianças em Manaus, Amazonas

Abstract Purpose: To evaluate the structural ocular sequelae of retinopathy of prematurity in children at risk for the disease in Manaus, Amazonas, Brazil. Methods: A prospective, cohort-type, observational study was conducted. Fifty-seven children at risk for this retinopathy, who were born in the public health system facilities, were referred for ophthalmic evaluation at a secondary eye hospital. Inclusion criteria were gestational age ≤ 32 weeks and/or birth weight ≤ 1500 g. Results: Eighteen (31.6%) children were diagnosed with any stage of retinopathy of prematurity during the study period, and four (7.0%) of them needed treatment. Structural ocular sequelae were identified in 3 of 56 children (5.3%), consisting of peripheral retinal detachment with macular dragging in 3 eyes of 3 children and macular involving retinal detachment in 2 eyes of 2 children. Associations between occurrence of retinopathy of prematurity and birth weight, gestational age at birth and days in oxygen were observed (p<0.05). Indication of treatment was associated with birth weight (p<0.05). Conclusion: Retinopathy of prematurity stands out as an important cause of avoidable blindness in Amazonas, affected 31.6 % of children at risk in the present paper, which in this same context, led to ocular strucutral sequelae in about 5.3% of these infants, either peripheral or macular involving retinal detachment. A local program for screening and treatment of the population at risk is necessary in order to avoid blindness from this disease, providing care to the public health system users that contemplates equality and universality of access.

Resumo Objetivo: Avaliar as sequelas oculares estruturais da retinopatia da prematuridade em crianças com risco para a doença em Manaus, Amazonas, Brasil. Métodos: Foi conduzido um estudo observacional prospectivo, do tipo coorte. Cinquenta e sete crianças que nasceram em um hospital público, com risco desta retinopatia, foram referênciadas para avaliação oftamológica em um hospital de olhos secundário. Critérios de inclusão foram idade gestacional ≤ 32 semanas e/ou peso ao nascer ≤ 1500 g. Resultados: Dezoito (31.6%) crianças foram diagnosticadas com retinopatia da prematuridade em qualquer estágio durante o período de estudo, quatro (7.0%) delas precisaram de tratamento. Sequelas oculares estruturais foram identificadas em 3 de 56 (5.3%) crianças, consistindo de descolamento de retina periférico com tração macular em 3 olhos de 3 crianças e descolamento de retina envolvendo a mácula em 2 olhos de 2 crianças. Associações entre a ocorrência de retinopatia da prematuridade e peso, idade gestacional e dias em oxigênio foram observadas (p<0.05). Indicação de tratamento foi associada com peso ao nascer (p<0.05). Conclusão: A retinopatia da prematuridade constitui uma importante causa de cegueira prevenível no Amazonas, acometeu 31.6% das crianças em risco no presente estudo, que neste mesmo contexto, levou a seqüelas estruturais oculares em cerca de 5.3% destas, tanto descolamento de retina periférico quanto envolvendo a mácula. Um programa local de triagem e tratamento da população de risco é necessário a fim de evitar a cegueira por esta comorbidade em Manaus, proporcionando cuidados aos usuários do sistema público de saúde que contemplem a igualdade e universalidade de acesso.

Referentes teóricos sobre la retinopatía de la prematuridad y sus criterios de pesquisa / Theoretical framework on retinopathy of prematurity and research criteria

Fundamento: La retinopatía de la prematuridad es una microangiopatía vasoproliferativa que se desencadena en los niños pretérminos y con factores de riesgo para su desarrollo. Puede avanzar, de no ser detectada y tratada, hacia la discapacidad visual e incluso la ceguera, de ahí la importancia de su pesquisaje. Se realizó una revisión sistemática sobre este tema relativamente joven en la oftalmología, en la base de datos Medline, que involucrara la última década, por ser esta la etapa en que Cuba ha desarrollado el trabajo de pesquisaje y tratamiento de la enfermedad. Objetivo: Actualizar los conocimientos acerca de la retinopatía de la prematuridad y sus criterios de pesquisa. Desarrollo: En el mundo se han realizado estudios multicéntricos para su mejor comprensión y manejo; y se han unificado criterios para su clasificación, siendo los principales factores de riesgo a los que se asocia la baja edad gestacional al nacimiento, el bajo peso extremo, el empleo de ventilación y oxígeno, entre otros. Existen varios tratamientos para evitar la ceguera por retinopatía de la prematuridad, siendo el láser el más utilizado actualmente, combinándose en muchos casos con terapéuticas novedosas como la vitrectomía y los antiangiogénicos. En cuanto a los criterios de pesquisa no existe uniformidad en el mundo, pero Cuba cuenta con un Protocolo Nacional para su manejo, que garantiza su diagnóstico oportuno y un tratamiento inmediato. Conclusiones: La retinopatía de la prematuridad es una enfermedad oftalmológica que constituye prioridad en Cuba, existiendo en el país un protocolo nacional para su manejo y así evitar el daño visual que puede ocasionar.

Background: The retinopathy of the prematurity is a vasoproliferative microangiopathy that is unchained in preterm children and with factors of risk for its development. It can advance, of not being detected and treated, toward the visual handicap and even the blindness, of there the importance of their inquire criteria. It was carried out a systematic revision on this relatively young topic in ophthalmology, in the database Medline that involved the last decade, to be this the stage in that Cuba has developed the inquire criteria work and treatment of the illness. Objective: To upgrade the knowledge about the retinopathy of the prematurity and its investigation approaches. Development: In the world there have been carried out multicentre studies for its best understanding and handling; and it have become unified approaches for its classification, being the main factors of risk to those that associates the low gestational age at birth, the extreme low weight, the ventilation and oxygen employment, among others. Several treatments exist to avoid the blindness for retinopathy of the prematurity, being the laser the more used at the moment, combining in many cases with therapeutic novel as the vitrectomy and the angiogenic. As for the investigation approaches uniformity doesn't exist in the world, but Cuba has a National Protocol for its handling that guarantees its opportune diagnosis and an immediate treatment. Conclusions: The retinopathy of the prematurity is an ophthalmologic illness that constitutes priority in Cuba, existing in the country a national protocol for its handling and this way to avoid the visual damage that can cause.

Epidemiología de la retinopatía del prematuro en servicios públicos de la Argentina durante 2008 / Epidemiology of retinopathy of prematurity in publics services from Argentina during 2008

El aumento de la supervicencia en prematuros y las deficiencias en su atención incrementan los casos de retinopatía del prematuro (ROP) la ROP afecta a pacientes con mayor peso (PN) y edad gestacional (EG) al nacer que en países desarrollados; se observan casos inusuales y oportunidades perdidas. Objetivo. Describir la epidemiología de la ROP 2008 y comparar los resultados con los del año anterior. Población y Método. Estudio obserbacional, descriptivo, retrospectivo. Población: pretérminos con PN menor 1500g y/o 0 menor o igual 32 sem EG y mayor igual 1500g y 33-36 sem con oxigenoterapia. Fuente: 31 servicios públicos de la Argentina. Variables: PN, EG, pesquisa oftalmológica, edad al 1er control, grado de ROP, necesidad y lugar de tratamiento y alta oftalmológica. Resultados. Respondieron 24 servicios (84200 nacimientos) donde se registraron 3371 niños con riesgo de ROP; 956 con PN menor 1500g. Pesquisados 90 por ciento, tardíamente 6 por ciento. Egresaron sin alta oftalmológica 93 por ciento. La incidencia de ROP fue de 11,93 por ciento; 26,25 por ciento en menor 1500g. Requirieron tratamiento 2,60 por ciento; 7 por ciento fueron menor 1500g; los casos inusuales fueron 20,3 por ciento y hubo una oportunidad perdida. Los casos tratados aumentaron 20 por ciento en 2008 respecto del 2007, sin alcanzar significación estadística. Las medias de PN, EG y los CI no variaron. El 75 por ciento de los tratamientos fueron in situ, sin cambios respecto a 2007. Conclusiones: Persisten indicadores preocupante de ROP en los servicios públicos de la Argentina. La falta de cambios en el 2008 respecto del 2007 hace suponer que no se han consolidado los conceptos sustantivos de la prevención. La pesquisa y el acceso al tratamiento son perfectibles.

Resultados de um programa de prevenção da cegueira pela retinopatia da prematuridade na Região Sul do Brasil / Results of a program for the prevention of blindness caused by retinopathy of prematurity in southern Brazil

OBJETIVO: Descrever os resultados do programa de prevenção da cegueira pela retinopatia da prematuridade implantado em um hospital universitário de nível terciário desde 2002, conforme os critérios de triagem adotados no Brasil, e comparar alguns aspectos com critérios preconizados para outros países. MÉTODOS: Estudo observacional descritivo incluindo todos os prematuros nascidos na instituição com peso de nascimento < 1.500 g ou idade gestacional < 32 semanas que sobreviveram até a sexta semana pós-natal no período entre outubro de 2002 e junho de 2006. Os exames oftalmológicos iniciaram na sexta semana de vida e foram repetidos de acordo com a necessidade até a regressão da doença. RESULTADOS: Foram incluídos 300 recém-nascidos e detectaram-se 18 casos de doença limiar e tratável (18/300, 6 por cento) com o critério brasileiro. Um dos pacientes não realizou tratamento, pois desenvolveu doença após a alta hospitalar e não retornou para exame a tempo de realizar o tratamento. Com critérios sugeridos para países desenvolvidos, haveria redução na totalidade de exames nas mesmas condições, porém não teriam sido detectados 11,76 por cento dos casos de doença limiar. CONCLUSÕES: O critério para a triagem de prematuros definido para o Brasil foi eficaz na detecção dos casos tratáveis da doença. Evitou-se a cegueira em 17 prematuros nesse período. A universalização deste programa em hospitais universitários ou nas redes de saúde pública e privada do país contribuiria para evitar uma das principais causas de cegueira infantil prevenível e tratável nos países em desenvolvimento. No momento atual, haveria risco em se modificar esse critério no Brasil.

OBJECTIVE: To describe the results of a program for the prevention of blindness caused by retinopathy of prematurity implemented in 2002 at a tertiary-care hospital, according to screening criteria adopted in Brazil, and to compare some aspects with the criteria adopted by other countries. METHODS: Descriptive observational study including all preterm infants born at this hospital weighing < 1,500 g at birth and/or gestational age < 32 weeks who survived up to the sixth week after birth, between October 2002 and June 2006. Ophthalmic examinations were performed from the sixth week of life and repeated as necessary until remission of the disease. RESULTS: A total of 300 newborns were included and there were 18 cases of treatable threshold disease (18/300, 6 percent) according to the Brazilian criteria. One patient was not treated because s/he developed the disease after hospital discharge and did not turn up for examination in order to initiate treatment. According to the criteria suggested by industrialized countries, the total number of exams would be reduced under the same circumstances, but 11.76 percent of the cases of threshold disease would not be detected. CONCLUSIONS: The Brazilian criteria for neonatal screening were efficient in detecting treatable cases. Blindness was averted in 17 preterm infants in the study period. The universal use of such program at teaching hospitals or in the public and private health networks could help prevent one of the main causes of preventable and treatable blindness among infants in developing countries. Currently, a change in these criteria in Brazil may compromise the diagnosis of some treatable patients.

Riesgo de Retinopatías relacionado con la oxigenoterapia en neonatos menores de 36 semanas de gestación en el Hospital Materno Infantil Germán Urquidi, gestión 2011 / Retinopathy risk related to oxygen in infants under 36 weeks gestation at Hospital Maternal and Child Germain Urquidi, management 2011

La retinopatía del prematuro provoca una lesión en los vasos retinianos originada por la inmadurez de la retina al nacer, asociada principalmente con la oxigenoterapia. El presente trabajo investigó el riesgo de Retinopatía del Prematuro relacionado con la oxigenoterapia en menores de 36 semanas de gestación en el área de Neonatología Intensiva del Hospital Materno Infantil Germán Urquidi de Cochabamba, bajo una metodología cuantitativa, descriptiva transversal y utilizando una guía de observación y de recolección de datos de las historias clínicas, hojas de registro de enfermería correspondientes a los meses de mayo a julio, gestión 2011. Las siguientes conclusiones son las más importantes, ya que incrementan el riesgo de retinopatía del prematuro: la administración de la oxigenoterapia por más de 96 horas fue más frecuente entre recién nacidos que recibían AVM, predomina la patología respiratoria entre los recién nacidos que recibieron oxigenoterapia, el 83.8% de los recién nacidos menores de 36 semanas de gestación presentan parámetros elevados de saturación de oxígeno, todos los menores de 1.500 gramos registran saturaciones no permitidas por encima de 93%. Por lo tanto, se recomienda al equipo de salud tomar en cuenta las recomendaciones sobre los cuidados y el manejo de la oxigenoterapia, con miras a prevenir la Retinopatía del Prematuro y sus complicaciones y contribuir a reducir la incidencia de ceguera infantil
