Clinical features and genetic analysis of two Chinese pedigrees affected with Joubert syndrome / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical characteristics and genetic basis of two Chinese pedigrees affected with Joubert syndrome.@*METHODS@#Clinical data of the two pedigrees was collected. Genomic DNA was extracted from peripheral blood samples and subjected to high-throughput sequencing. Candidate variants were verified by Sanger sequencing. Prenatal diagnosis was carried out for a high-risk fetus from pedigree 2.@*RESULTS@#The proband of pedigree 1 was a fetus at 23+5 weeks gestation, for which both ultrasound and MRI showed "cerebellar vermis malformation" and "molar tooth sign". No apparent abnormality was noted in the fetus after elected abortion. The fetus was found to harbor c.812+3G>T and c.1828G>C compound heterozygous variants of the INPP5E gene, which have been associated with Joubert syndrome type 1. The proband from pedigree 2 had growth retardation, mental deficiency, peculiar facial features, low muscle tone and postaxial polydactyly of right foot. MRI also revealed "cerebellar dysplasia" and "molar tooth sign". The proband was found to harbor c.485C>G and c.1878+1G>A compound heterozygous variants of the ARMC9 gene, which have been associated with Joubert syndrome type 30. Prenatal diagnosis found that the fetus only carried the c.485C>G variant. A healthy infant was born, and no anomalies was found during the follow-up.@*CONCLUSION@#The compound heterozygous variants of the INPP5E and ARMC9 genes probably underlay the disease in the two pedigrees. Above finding has expanded the spectrum of pathogenic variants underlying Joubert syndrome and provided a basis for genetic counseling and prenatal diagnosis.

Phenotype and genotype analysis of a pedigree affected with Joubert syndrome due to variant of TMEM237 gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the pathogenesis of two siblings (including a fetus) from a pedigree affected with Joubert syndrome.@*METHODS@#Peripheral blood samples of the proband and his parents as well as amniotic fluid and abortion tissues of the fetus were collected. Part of the samples were used for the extraction of DNA, and whole exome sequencing (WES) was carried out to screen potential variants in the proband and his parents. Suspected variants were subjected to bioinformatics analysis with consideration of the clinical phenotype, and were verified by Sanger sequencing of the proband, fetus and their parents.The remainders were used for the extraction of RNA, and the mechanism of splicing variant was validated by reverse transcription-PCR (RT-PCR).@*RESULTS@#WES showed that both patients have carried c.175C>T (p.R59X) and c.553+1G>A compound heterozygous variants of the TMEM237 gene. Among these, c.175C>T was a nonsense mutation inherited from the asymptomatic mother, while c.553+1G>A was an alternative splicing mutation inherited from the asymptomatic father. RT-PCR showed that this variant has resulted in aberrant splicing by exon skipping.@*CONCLUSION@#The compound heterozygous variants of the TMEM237 gene probably underlay the etiology of Joubert syndrome in this pedigree. Above finding has enriched the phenotype and variant spectrum of the TMEM237 gene, and facilitated genetic counseling and prenatal diagnosis for the family.

Phenotypic analysis and variant identification of a fetus with Joubert syndrome 17 / 中华医学遗传学杂志

OBJECTIVE@#To analyze the phenotype and genetic variant of a fetus with dysplasia of cerebellar vermis.@*METHODS@#Gestational status and family history of the gravida was taken in combination with the imaging results of the fetus. Following elected abortion, fetal tissue and peripheral blood samples of the couple were collected for the extraction of genome DNA. Whole exome sequencing was carried out to screen potential variant associated with the phenotype of the proband. Specific PCR primers were designed to verify the results by Sanger sequencing.@*RESULTS@#Prenatal ultrasound revealed that the fetal vermis cerebellum was poorly developed, which was similar to the previous pregnancy. Whole exome sequencing revealed that the fetus has carried compound heterozygous variants of the CPLANE1 gene, namely c.7978C>T and c.7169delT, which were respectively inherited from the husband and wife.@*CONCLUSION@#The c.7978C>T and c.7169delT compound heterozygous variants of the CPLANE1 gene probably underlay the dysplasia of cerebellar vermis in the fetus, which has provided a basis for genetic counseling and prenatal diagnosis.

Exame ultrassonográfico no diagnóstico de coloboma retinocoroidiano bilateral / Ultrasonographic examination in the diagnosis of bilateral retinochoroid coloboma

Resumo Relatamos aqui o caso de E.R.S.S., feminino, 43 anos, diagnosticada com coloboma de retina e coroide bilateral, afim de enfatizar a importância dos exames pré-operatórios, até mesmo de uma boa tomada de projeção luminosa, a qual está sendo muitas vezes relegada a um patamar desprezível dentro da prática oftalmológica. Salientamos também que o exame ultrassonográfico prévio à indicação cirúrgica é de suma importância, no entanto, esse deve ser realizado por profissional experiente e sua correta interpretação deve ser exaustivamente procurada para que erros interpretativos não se transformem em conduta clínico cirúrgica inadequada e consequentes danos, muitas vezes, irreparáveis. Considerando-se todos os aspectos e complicações do coloboma já citados nesse relato, a conduta diante de um diagnóstico dessa malformação deve ser: pesquisar associação com outras doenças oculares e/ou sistêmicas (CHARGE: coloboma, cardiopatia congênita, atresia de coana com múltiplas anomalias), realizar tratamento e acompanhamento em caso de complicações (Ex. descolamento de retina, ambliopia e estrabismo) e prevenção é feita através de aconselhamento genético.

Abstract We report here the case of E.R.S.S. female, 43 years old, diagnosed with bilateral coloboma of choroid and retina, in order to emphasize the importance of preoperative exams, even a good shot of light projection, which is often being relegated to a negligible level in ophthalmological practice.We emphasize also that the ultrasound examination prior to the surgical indication is of paramount importance, however,this should be performed by experienced professional and the correct interpretation must be thoroughly searched for interpretative errors not become inadequate surgical clinical conduct and consequential irreparable damage. Considering all aspects and complications already mentioned in this report, coloboma to conduct before a diagnosis of this malformation should be: search for association with other eye diseases and/or systemic (CHARGE: coloboma, congenital heart defect, atresia of posterior nasal apertures with multiple anomalies), performing and monitoring treatment in case of complications (E.g. retinal detachment, amblyopia and strabismus) and prevention is made through genetic counseling.

Anestesia total intravenosa libre de opioides en un paciente con síndrome de Joubert: caso clínico / Opioid free total intravenous anesthesia in Joubert syndrome: Case report

Linguagem, comportamento e neurodesenvolvimento na Síndrome de Joubert: relato de caso / Language, behavior and neurodevelopment in Joubert syndrome: a case report

RESUMO A síndrome de Joubert (SJ) é uma condição genética heterogênea, rara, do grupo das ciliopatias. Mais de 20 genes foram identificados relacionados com este fenótipo. As principais manifestações incluem hipotonia, ataxia, atraso psicomotor, apraxia oculomotora e anormalidades respiratórias neonatais. O objetivo deste artigo foi apresentar achados de linguagem e neurodesenvolvimento de um indivíduo com diagnóstico da SJ. Foi realizada a anamnese, avaliação genética clínica, observação do comportamento comunicativo, avaliação da linguagem, o Teste de Screening de Desenvolvimento Denver-II (TSDD-II) e a Early Language Milestone Scale (ELMS). Os principais achados da Ressonância Magnética do encéfalo mostraram grave hipoplasia do vérmis cerebelar, “sinal do dente molar”, tronco cerebral hipoplásico, atrofia dos hemisférios cerebelares. A avaliação da linguagem mostrou ausência de oralidade, prejuízo na recepção da linguagem, confirmando o diagnóstico de transtorno de linguagem, com grau de comprometimento grave. O TSDD-II e a ELMS comprovaram a observação e avaliação clínica e indicaram atraso grave nos domínios motor, autocuidados e de linguagem receptiva e expressiva. Diante da presença de hipotonia, ataxia, atraso psicomotor e anormalidades respiratórias neonatais é imprescindível a realização de exame por imagem e avaliação genética para o diagnóstico desta condição, tão complexa, com necessidades terapêuticas peculiares. Este conjunto de achados, associado à história familial e características fenotípicas peculiares reforçam o diagnóstico genético clínico da SJ. Esta síndrome genética é pouco reconhecida e merece ser apresentada para o reconhecimento da comunidade científica, visando o diagnóstico correto e planejamento terapêutico que minimize os efeitos deletérios desta condição.

ABSTRACT The Joubert syndrome (JS) is a rare, heterogeneous genetic condition among the ciliopathies. More than 20 genes have been identified associated with this phenotype. The main manifestations include hypotonia, ataxia, psychomotor retardation, ocular-motor apraxia and neonatal respiratory abnormalities. The objective of this paper was to present language and neurodevelopmental findings of an individual diagnosed with JS. The following procedures were performed: anamnesis, clinical genetic evaluation observation of communicative behavior, evaluation of language, the Denver Developmental Screening Test II (DDST-II) and the Early Language Milestone Scale (ELMS). The main findings of the MRI brain showed severe hypoplasia of the cerebellar vermis, “molar tooth sign”, hypoplastic brain stem and atrophy of the cerebellar hemispheres. The observation and evaluation of the language showed no oral, impaired reception of language, confirming the diagnosis of language disorder with severe degree of impairment. The DDST-II and the ELMS confirmed the observation and clinical assessment and indicated serious delay in motor domains, self-care and receptive and expressive language. Given the presence of hypotonia, ataxia, delayed psychomotor and neonatal respiratory abnormalities it is essential to carry out examination imaging and genetic evaluation for the diagnosis of this condition, so complex, with unique therapeutic needs. This set of findings, along with the familial history and unique phenotypic characteristics reinforce the clinical genetic diagnosis JS. This genetic syndrome is rarely recognized and deserves to be presented to the recognition of the scientific community, targeting the correct diagnosis and treatment planning that minimizes the deleterious effects of this condition.

Retinopatia proliferativa em paciente com anemia falciforme: relato de caso / Proliferative retinopathy in a patient with sickle cell anemia: case report

A Anemia Falciforme é uma anemia hemolítica que resulta da mudança estrutural na molécula de hemoglobina, devido à mutação no gene de globina no cromossomo 11. Esta mutação causa uma substituição de ácido glutâmico por valina na posição 6, com a formação da hemoglobina S. A hemoglobina S exposta à desoxigenação desencadeia fenômenos de vaso-oclusão na microcirculação com isquemia e injúria aos tecidos. As alterações oftalmológicas mais importantes relacionadas à Anemia Falciforme ocorrem principalmente pela obstrução dos vasos da retina. A retinopatia falciforme apresenta várias manifestações fundoscópicas, podendo, inclusive, levar à amaurose. Os autores relatam caso de paciente com retinopatia proliferativa falciforme severa e baixa acuidade visual que evoluiu com resposta favorável após intervenção terapêutica. Os autores discutem as opções terapêuticas disponíveis e a necessidade da avaliação oftalmológica periódica aos pacientes com Anemia Falciforme, visando o diagnóstico e monitoramento de progressão ou regressão das lesões da retina.

Congenital Aniridia: Long-term Clinical Course, Visual Outcome, and Prognostic Factors

PURPOSE: To describe the clinical course of congenital aniridia and to evaluate prognostic factors for visual outcome after long-term follow-up. METHODS: The medical records of 120 eyes from 60 patients with congenital aniridia were retrospectively reviewed. The prevalence and clinical course of ophthalmic characteristics, systemic disease, refractive errors, and visual acuity were assessed. Prognostic factors for final visual outcomes were analyzed. RESULTS: Aniridic keratopathy developed in 82 (69%) of 119 eyes. Macular hypoplasia was observed in 70 eyes of 35 patients (91%). Cataract was observed in 63 of 120 eyes (53%). Nystagmus was present in 41 patients (68% of 60 patients) at the initial visit but decreased in five patients (8% of 60 patients). Ocular hypertension was detected in 19 eyes (20% of 93 eyes), six (32% of 19 eyes) of which developed secondarily after cataract surgery. The mean changes in spherical equivalent and astigmatism during the follow-up period were -1.10 and 1.53 diopter, respectively. The mean final visual acuity was 1.028 logarithm of minimal angle of resolution. Nystagmus and ocular hypertension were identified as prognostic factors for poor visual outcome. CONCLUSIONS: Identification of nystagmus and ocular hypertension was important to predict final visual outcome. Based on the high rate of secondary ocular hypertension after cataract surgery, careful management is needed.

Alterações eletrofisiológicas na doença de Oguchi / Electrophysiological findings in Oguchi disease

Descrever as alterações eletrofuncionais em um caso raríssimo da Doença de Oguchi. Paciente do sexo feminino, italiana de 17 anos de idade se queixava de cegueira noturna. A resposta escotópica de bastonetes, do ERG era não registrável. A resposta escotópica ao estímulo branco forte demonstrava uma diminuição de amplitude da onda B. As respostas ao flicker de 30Hz e ao EOG eram dentro dos limites da normalidade. Era presente o fenômeno de Mizuo-Nakamura. Os exames eletrofuncionais são muito importantes no diagnóstico de certeza da doença de Oguchi. É nítida, no presente caso, a discordância entre EOG e ERG. Considerando a função dos bastonetes, as respostas normais do EOG contrastam com a ausência de respostas dos bastonetes em condições escotópicas no ERG. Mais estudos são necessários para entender o complexo mecanismo eletrofuncional dessa doença e melhor definir a origem dos componentes sensíveis à luz do EOG...

To describe the electrophysiological alterations in a very rare case of Oguchi's disease. A 17-year-old italian girl complaining of night blindness underwent complete ophthalmological exams, including electrophysiological tests. Rod responses were nondetectable in full-field electroretinogram (ERG). The photopic ERG funtions, including the 30 Hz flicker ERG response was normal, while the scotopic b-wave was diminished in amplitude. The electrooculography (EOG) ratios within the normal range were 208% in the right eye and 222% in the left eye. The Mizuo-Nakamura phenomenon was present. The electrophysiological tests are important tools in Oguchi's disease diagnosis. In the present case, it's clear the non correspondance between EOG and ERG. Considering the rod function, the normal EOG ratio contrast with non-detectable rod ERG responses. More studies are necessary to understand the compless electrofuntional mecanism of the disease helping to understand the origin of the light-sensitive component of the EOG...

Unusual macular thickness in Alport syndrome: case report / Espessura macular atípica na síndrome de Alport: relato de caso

This case report describes the presence of bilateral macular atrophy in a patient with Alport syndrome and compares this finding with literature. At fundoscopy, there was a discrete circumscribed macular thinning showing intense retinal pigment epithelium color and the presence of whitish circular retinal lesions ("dots" and "flecks") at nasal mid periphery of both eyes. Optical coherence tomography showed bilateral partial atrophy of the neurosensory retina in the macula, with a greater extent in the temporal region. This case describes a rare ophthalmological finding in Alport syndrome and important to be recognized for a precise diagnosis as well as for determining visual prognosis.

Este relato de caso descreve a presença de atrofia macular bilateral em uma paciente com síndrome de Alport e compara este achado com a literatura. Ao exame fundoscópico, havia discreto afinamento macular circunscrito demonstrando a coloração intensa do epitélio pigmentado da retina e a presença de lesões retinianas circulares esbranquiçadas ("dots" e "flecks") na média periferia nasal em ambos os olhos. A tomografia de coerência óptica identificou atrofia parcial da retina neurossensorial bilateral na mácula, com maior extensão na área temporal. O caso descreve uma alteração oftalmológica rara da síndrome de Alport e de importante reconhecimento para precisar o diagnóstico e também para determinar o prognóstico visual.

Síndrome de malformação vascular retinocefálica congênita unilateral (síndrome de Wyburn-Mason ou síndrome de Bonnet-Dechaume-Blanc) ? Relato de caso raro e revisão de literatura / Unilateral retinocephalic vascular malformation syndrome (Wyburn-Mason or BonnetDechaume-Blanc) ? Case report and literature review

A síndrome de Wyburn-Mason ou Bonnet-Dechaume-Blanc representa uma doença neurocutânea congênita rara, não hereditária, do grupo das facomatoses, caracterizada por anormalidades vasculares ipsilaterais comprometendo a face, as vias da visão e o encéfalo, não sendo obrigatória a existência concomitante dos três locais para a confirmação diagnóstica. Acredita-se que tal distúrbio seja atribuído a um defeito de desenvolvimento do mesoderma primitivo vascular. Em 1937 e 1943, foram relatados na literatura os primeiros casos de pacientes com malformações vasculares unilaterais afetando o olho, o cérebro e a face, com tamanha riqueza de detalhes, que tal quadro sindrômico passou a receber o nome dos autores responsáveis pelas publicações. A denominação de malformações vasculares retinocefálicas unilaterais (MVR) foi utilizada primeiramente em 1974. A síndrome de Wyburn-Mason tipicamente se apresenta após a terceira década de vida e se manifesta de várias formas. As manifestações oculares são as mais comuns, enquanto as manifestações cutâneas faciais podem não ser encontradas. No presente trabalho, apresentamos um caso raro da síndrome de malformação vascular retinocefálica unilateral em paciente adulta-jovem, do sexo feminino, submetida a ressecções cirúrgicas de lesões retiniana e encefálica supratentoriais, ipsilaterais, em tempos diferentes, com outra lesão infratentorial, assintomática, submetida a tratamento conservador até o momento. O anatomopatológico das lesões confirmou tratar-se de hemangioma cavernoso.

Wyburn-Mason syndrome or Bonnet-Blanc-Dechaume syndrome represents a rare congenital neurocutaneous disease, nonhereditary group of phakomatoses characterized by vascular abnormalities affecting the ipsilateral face, the vision?s pathways and brain, was not mandatory the coexistence of three locations to confirm the diagnosis. It is believed that the disorder is attributed to a defect in development of primitive vascular mesoderm. In 1937 and 1943, cases reported of patients with unilateral vascular disease affecting the eye, brain and face, with such wealth of detail, such as syndrome started to receive the name of those authors in the literature. The name of unilateral retinocephalic vascular malformation syndrome (MVR) was primarily used by in 1974. The Wyburn-Mason syndrome typically presents after the third decade of life and manifests itself in many ways. Ocular manifestations are the most common, while the facial skin manifestations cannot be found. In this paper, we present a rare case of unilateral retinocephalic vascular malformation syndrome in an adult woman, who underwent surgical resection of brain injuries and retinal supratentorial ipsilateral lesion at different times, with another infratentorial lesion, asymptomatic and underwent conservative treatment for a while. The pathology of the lesions confirmed cavernous hemangioma.

A Developmental Mechanism of Spontaneous Reattachment in Rhegmatogenous Retinal Detachment

This retrospective observational case series on eyes from three patients was done to elucidate the developmental mechanism of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD). The study eyes of each patients showed evidence of retinal break and diffuse retinal pigmentary change. Ultrasound biomicroscopic examination revealed vitreous fibers attached to the area around the retinal break. Posterior vitreous attachment was confirmed in each eye. A thin fibrovascular membrane incompletely sealing the retinal break was noted in one case. We suggest that the vitreous attachment around the retinal break and the sealing of the break with adjacent vitreous fibers seem to be involved in the developmental mechanism of SRRRD.

Mobile phone radiations, possible disruptor to early retinal development

This study was conducted with an objective to investigate the effects of mobile phone induced radiations on retinal morphogenesis of chick embryo. Experimental Study. This study was conducted at Anatomy department, Regional Centre, College of Physicians and Surgeons Pakistan, Islamabad from Jan. 2006 to Jan. 2007. Chicken embryos were exposed to mobile phone silent mode ringing by placing a GSM operated phone in the centre of the fertilized eggs developing in the incubator. This phone was ringed upon for 15 minutes twice daily for one experimental subgroup and 25 minutes twice for the other subgroup. The control and experimental groups were sacrificed at the end of 10 post incubation days. The retinae of the embryos were dissected out and statistically compared for the heights of different retinal layer after paraffin processing of sections. For lower dosage [15 minutes of ringing] of mobile phone induced EMFs. Thickness of the rods and cones layer and inner plexiform layer of the treated subgroup was significantly less than the control. On increasing the dosage to 25 minutes, thickness of the pigment epithelial layer of the treated group was significantly more than the control group. All the other layers were more in thickness in this subgroup but this difference was not statistically significant. The results of the study conclude that mobile phone radiations have a dose dependant regulatory effect on the early developmental process of chick embryo retina. EMFs dose Mobile phone induced EMFs disrupt the developmental process of embryonal retinogenesis. This effect is influenced differently at different levels exposure

Unilateral Peters' Anomaly with Chorioretinal Coloboma in the Other Eye

An 18-year-old man presented with poor vision in both eyes that had been present since birth. Central corneal opacity and inferior peripheral sclerocornea with iridocorneal adhesion were observed upon anterior segment examination of the left eye. A coloboma of the iris was observed in the patient's right eye, which manifested as a small notch in the inferior pupillary margin and cataract. Fundus examination of the right eye showed a large inferior chorioretinal coloboma involving the optic disc and macula. It is essential to examine the fundus in detail, if possible, in cases of Peters' anomaly, because these patients may have congenital anomalies such as chorioretinal coloboma.

Síndrome de Stickler: aspectos gerais / Stickler syndrome: general aspects

A síndrome de Stickler é a principal causa de descolamento de retina entre os fatores hereditários, sendo ainda pouco conhecida, apesar de comum na Europa. Constitui-se em doença autossômica dominante, progressiva, causada a partir de mutações em genes responsáveis pela síntese de colágeno, como COL2A1, COL11A1 e COL11A2. Possui variada sintomatologia, inclusive dentro de uma mesma família. Ocorrem alterações otorrinolaringológicas, oftalmológicas, ortopédicas e sistêmicas, como hipoacusia, fenda palatina, face plana, nariz achatado, miopia intensa, catarata, glaucoma, articulações hiperflexíveis e prolapso da valva mitral. Dentre as principais complicações dos indivíduos afetados se encontram surdez neurossensorial, descolamento da retina e cegueira. O artigo se constituiu em uma revisão bibliográfica sobre a síndrome de Stickler, abordando os principais sinais e sintomas clínicos, diagnóstico e tratamento, através da pesquisa e seleção de artigos científicos na biblioteca virtual BIREME, predominantemente de 2000 a 2006, associados a artigos clássicos sobre o tema. Devido a seu caráter progressivo, torna-se fundamental o diagnóstico precoce, na tentativa de evitar complicações que prejudiquem o desenvolvimento do indivíduo, havendo necessidade de tratamento multidisciplinar, devido ao acometimento de múltiplas estruturas.

Síndrome de Aicardi: relato de caso e achados radiológicos / Aicardi syndrome: a case report and radiologic findings

Neste trabalho relatam-se os achados da síndrome de Aicardi, um distúrbio de etiologia desconhecida composta por espasmos múltiplos, lacunas coriorretinianas e agenesia do corpo caloso. Os autores apresentam um caso desta síndrome, com clínica e achados de ressonância magnética característicos. A doença, apesar de considerada rara, apresenta achados de imagem característicos. Nos últimos anos, a importância da ressonância magnética tem aumentado expressivamente,uma vez que demonstra outros achados além da agenesia do corpo caloso, tornando o papel do radiologista muito importante na suspeição diagnóstica desta enfermidade.

The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a caseof Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstratingother findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

clinical utility of a non-mydriatic retinal camera in a diabetes clinic

we aim to evaluate a non-mydriatic retinal camera as a safe and efficacious screening tool, for diabetic retinopathy, in diabetes centers. 221 consecutive patients attending a Diabetes Center submitted to retinal photographs using a non-mydriatic camera. Patients were included if they had not had previous laser therapy and if they had a formal ophthalmologic consultation within 6 months of the photography Four endocrinologists reviewed the retinal photographs and recommended an interval [urgent referral, early referral, non-referral] for ophthalmologic assessment. Endocrinologists' grades were compared against the gold standard of ophthalmological findings. The endocrinologists were privy only to the patient's age, type and duration of diabetes mellitus. Twenty-seven cases were deemed as requiring early referral by the ophthalmologists. The endocrinologists agreed with ophthalmologist referral times in 27, 26, 23 and 27 cases respectively. Two cases requiring urgent referral according to the ophthalmologists were also judged as requiring urgent referral by all endocrinologists. A mean sensitivity of 95.4% [95% CI 88.5%-100%] was attained. The use of a non-mydriatic camera to determine need for ophthalmologic referral was found to be safe and efficacious, with no serious delays in referral noted. On average this tool can safely defer 53.5% of routine ophthalmologic referrals without any risk to the patient's eyesight
