Prevalência de alterações oculares em lactentes no primeiro ano de vida / Prevalence of ocular alterations in infants in the first year of life

Objetivo: Analisar a prevalência de anormalidades oculares em um grupo de lactentes e descrever quais delas não seriam detectadas pelo teste do reflexo vermelho (TRV); analisar os aspectos críticos para o cuidado das anormalidades oculares encontradas. Introdução: Dados globais em relação à prevalência e causas de alterações oculares são escassos, em função da dificuldade de realizar trabalhos de base populacionais. Estima-se que atualmente existam cerca de 1.4 milhões de crianças com deficiência visual em todo o mundo e que metade dos casos sejam atribuídos à causas que têm prevenção ou tratamento. A deficiência visual na infância tem impacto direto sobre todos os aspectos do desenvolvimento infantil. O TRV é um método de rastreio de alterações na transparência dos meios oculares implementado no estado do Rio de Janeiro desde 2002. Ele tem auxiliado na prevenção da deficiência visual na infância, através da detecção precoce de alterações na transparência dos meios oculares. Métodos: Foi realizado um estudo transversal, dentro de um estudo de coorte prospectivo que avaliou mulheres gestantes e seus recém-nascidos (ZIP Study International Cohort Study of Children Born to Women Infected with Zika Virus During Pregnancy). As gestantes do estudo original foram recrutadas em 8 clínicas da família do município do Rio de Janeiro e seus recém-nascidos foram submetidos a um exame oftalmológico no primeiro ano de vida. Foi realizado o exame externo para avaliação das pálpebras, esclera, córnea, conjuntiva e cristalino, além da avaliação da motilidade extra ocular e oftalmoscopia indireta para avaliação do fundo de olho sob midríase. Foi feita uma análise descritiva e da prevalência das alterações oculares encontradas, analisando quais delas trariam comprometimento ao desenvolvimento visual e necessitariam de acompanhamento oftalmológico até resolução total do quadro. Além disso, quais dessas alterações não seriam detectadas apenas com o exame de rastreio disponível atualmente, o TRV. A refração, apesar de ter sido realizada durante a avaliação dos lactentes, não foi analisada. A partir das análises realizadas, foi feita uma avaliação dos aspectos críticos para o cuidado das alterações encontradas. Resultados: Foram avaliados 561 lactentes entre 09/03/2017 e 27/02/2019. A mediana de idade dos lactentes foi 1 mês (IQR 25-75: 1-2 meses). A prevalência de alterações oculares encontradas ao exame oftalmológico nos lactentes foi 5,7% (32/561), sendo 1,6% (9/561) passíveis de identificação pelo TRV. Todas as anormalidades posteriores e as que demandam a dilatação das pupilas para o seu diagnóstico não foram detectadas pelo TRV. Estas correspondem a 72% (23/32) de todas as alterações oculares encontradas. E foram elas: sinéquia posterior de íris, hipoplasia de nervo óptico, relação escavação/disco óptico aumentada, palidez de disco óptico bilateral, hemorragia retiniana, atenuação vascular, anormalidades da mácula e retinopatia da prematuridade. Noventa e quatro por cento (30/32) dos lactentes que apresentaram alteração ao exame precisaram de encaminhamento para acompanhamento oftalmológico. Conclusão: O TRV não identifica as alterações do segmento posterior do olho, que representam a maioria das anormalidades encontradas e que, apesar de não necessitarem de cirurgia, precisam de acompanhamento.

Purpose: To analyze the prevalence of ocular abnormalities in a group of infants, to describe those that would not be detected by the red reflex test (RRT) and to analyze the critical aspects for the care of eye abnormalities. Introduction: Global data regarding the prevalence and causes of ocular alterations are scarce, due to the difficulty of carrying out population-based studies. It is estimated that there are currently around 1.4 million children with visual impairment worldwide and that half of the cases are attributed to causes that are preventable or treatable. Visual impairment in childhood has a direct impact on all aspects of child development. RRT is a method of tracking changes in the transparency of ocular means implemented in the state of Rio de Janeiro since 2002. It has helped to prevent visual impairment in childhood, through the early detection of changes in the transparency of ocular means. Methods: A cross-sectional study was carried out within a prospective cohort study that evaluated pregnant women and their newborns (ZIP Study- International Cohort Study of Children Born to Women Infected with Zika Virus During Pregnancy). The pregnant women in the original study were recruited from 8 "Clínicas da Família" in the city of Rio de Janeiro and their newborns underwent an eye examination in the first year of life. An external examination was performed to assess the eyelids, sclera, cornea, conjunctiva and lens, in addition to the evaluation of extraocular motility and indirect ophthalmoscopy to evaluate the fundus of the eye under pupillary dilation. From the collected data, a descriptive analysis was made and t prevalence of ocular abnormalities found in the infants who participated in the study, analyzing which ones would compromise the visual development and would need ophthalmological follow-up until full resolution of the condition. Furthermore, which of these abnormalities would not be detected only by the screening test currently available, the RRT. Despite having being performed, the refraction was not analized. From the analyzes carried out, an assessment of the critical aspects for the care of the abnormalities found was carried out. Results: 561 infants were evaluated between 03/09/2017 to 02/27/2019. The infants' median age was 1 month (IQR 25-75: 1-2 months) and the prevalence of ocular abnormalities found on ophthalmological examination was 5.7% (32/561). The prevalence of ocular abnormalities detected by RRT in the study was 1.6% (9/561). All posterior abnormalities and those that require pupil dilation for diagnosis were not detected by the RRT. These correspond to 72% (23/32) of all ocular abnormalities. These were: posterior iris synechia, optic nerve hypoplasia, increased cup/optic disc ratio, bilateral optic disc pallor, retinal hemorrhage, vascular attenuation, macular abnormalities, and retinopathy of prematurity. Most ocular abnormalities, even transient ones with a potential for benignity, need ophthalmological follow-up until the complete resolution of the condition. In the study, 94% (30/32) of the infants who presented abnormalities on the exam needed to be referred for ophthalmological follow-up.

Scheimpflug imaging in anterior megalophthalmos.

We report an anterior megalophthalmos case with decreased corneal thickness and show the findings using Scheimpflug imaging. A 25-year-old male was diagnosed with anterior megalophthalmos. In both eyes, enlarged corneal length was measured. Beside a comparatively good visual acuity, a thin but clear cornea, a fairly deep anterior chamber, and central lens opacity were found. Scheimpflug images were taken using Pentacam HR. Scheimpflug-based imaging can provide us new data at the examination of this syndrome affecting the whole anterior segment.

Prevalence of plateau iris configuration in primary angle closure glaucoma using ultrasound biomicroscopy in the Indian population.

Purpose: To report the prevalence of plateau iris in patients with primary angle closure glaucoma (PACG), in North India. Materials and Methods: The patients with PACG, attending the glaucoma services at a tertiary care center in North India were included in the study. All patients had undergone Nd-YAG laser peripheral iridotomy at least four weeks prior to inclusion in the study. Four weeks prior to inclusion in the study, none of the patients had used pilocarpine. Ultrasound Biomicroscopy (UBM) images were qualitatively evaluated and plateau iris configuration was defined in an eye if the following criteria were fulfilled in two or more quadrants: anteriorly directed ciliary process supporting the peripheral iris, steep rise of iris root from its point of insertion followed by a downward angulation from the corneoscleral wall, absent ciliary sulcus, and iridotrabecular contact in the same quadrant. Results: One hundred and one eyes were included in the study. There were 63 (62.4%) females and 38 (37.6%) males. The mean age of the patients was 57.8 ± 9.5 years (range: 42 to 78 years). The mean axial length in the study population was 22.2 ± 1.1 mm. The mean spherical equivalent refraction was 0.06 ± 1.12 D. The mean intraocular pressure was 18.5 ± 4.7 mmHg (range: 12 – 24 mmHg). Twenty-nine (28.7%) subjects were diagnosed with plateau iris on the basis of above-defined criteria. Of the 29 eyes, 18 (62.1%) subjects had plateau iris in two quadrants, nine (31.03%) in three quadrants, and two (6.8%) had this configuration in all the four quadrants. Conclusions: Approximately 30% of the eyes with PACG had plateau iris on UBM. Plateau iris was very often the cause for residual angle closure following laser peripheral iridotomy in Indian eyes with PACG.

Refractory seizures with global developmental delay: A rare cause.

Aicardi syndrome is a genetic disorder characterized by the triad of infantile spasm in flexion, callosal agenesis and ocular abnormalities (chorioretinal lacunae, coloboma of optic disc). We report a typical case of Aicardi syndrome with all the classical features.

Eye and vision defects in under-five-year-old children in Oman: a public health intervention study

To identify under-five-year old children with vision or ocular defect in two provinces [Wilayats] of central Oman in 2006. Public health intervention study. Ocular examination in Manah Wilayat was conducted by nursing staff of the primary health center [PHC] and in Mudhaiby Wilayat was conducted by a trainee Omani optometrist Abnormal sized eyeball, strabismus nystagmus and white pupil were recorded. Visual acuity was tested by LOGMAR chart with Lea's symbols in children >2 years of age and preferential viewing was assessed by Lea's grating paddle or 'Hiding Heidi' picture in children /= 0.32 in 386/448 [86.2%] eyes. Preferential looking test suggested that half of the children had defective vision [>2cpcm]. Screening at '1-2 year' and '3-4 years' age group could significantly predict eye problems [P

Down syndrome associated malformations.

This paper reports the associated malformations and the clinical findings that were observed in 417 cytogenetically confirmed Down Syndrome patients. Among them congenital heart defects have occurred more frequently [75; 17.98%] than osteoarticular malformations [23; 5.52]; eye anomalies [22; 5.27%]; and gastroenterological malformations [n 16; 3.84%]. With regard to prognosis and treatment appropriate counselling has been given to Down Syndrome patients and their families.

Retinopatía del prematuro. Frecuencia en el Servicio de Neonatología del Instituto Nacional de Pediatría del 1o. de marzo de 1988 al 28 de febrero de 1989 / Retinopathy of the premature: frequence in the Service of Neonatology of Instituto Nacional de Pediatría from march 1st of 1988 to february 28 of 1989

Se examinaron los ojos de 25 niños recién nacidos prematuros que ingresaron al Servicio de Neonatología del Instituto Nacional de Pediatría en el período comprendido entre 1o. de marzo de 1988 al 28 de febrero de 1989. Todos pesaron menos de 2000 g al momento del nacimiento; llegaron al servicio en sus primeras 24 horas de vida; recibieron oxígeno y fueron dados de alta por mejoría. Cinco de estos niños desarrollaron retinopatía del prematuro en su fase aguda. Cuatro de ellos presentaron una retinopatía grado I y uno, retinopatía grado II de acuerdo a la clasificación Internacional de la Retinopatía del Prematuro publicada en 1984. Los niños que desarrollaron retinopatía, fueron pacientes con peso y una edad gestacional menor al nacimiento; fueron trasfundidos un mayor número de veces; recibieron FIO2 entre 80 y 100% por más tiempo, con una duración total de oxigenoterapia mayor que los niños que no la desarrollaron
