RESUMO
PURPOSE: To present applications of anterior segment optical coherent tomography (AS OCT) for anomalies of the eye in a Polish paediatric cohort. MATERIALS AND METHODS: Seventy-four eyes of infants and older children were examined. The majority of them underwent general anaesthesia to allow OCT to be performed in the operating room, but a few were examined in a routine way. We focused on corneal, anterior chamber, iris, and lens disorders. Measurements included corneal morphology, anatomy of the anterior chamber, and general involvement of surrounding tissues in pathologic lesions. RESULTS: We divided the paediatric patients into several groups by considering the type of disease and involvement of particular tissues. The groups were selected based on OCT usefulness in describing their ocular disorders. CONCLUSION: The collected anterior segment disorders showed huge usefulness for paediatric diagnosis and treatment planning.

PURPOSE: To evaluate structural grading and quantitative segmentation of foveal hypoplasia using handheld OCT, versus preferential looking (PL), as predictors of future vision in preverbal children with infantile nystagmus. DESIGN: Longitudinal cohort study. PARTICIPANTS: Forty-two patients with infantile nystagmus (19 with albinism, 17 with idiopathic infantile nystagmus, and 6 with achromatopsia) were examined. METHODS: Spectral-domain handheld OCT was performed in preverbal children up to 36 months of age. Foveal tomograms were graded using our 6-point grading system for foveal hypoplasia and were segmented for quantitative analysis: photoreceptor length, outer segment (OS) length, and foveal developmental index (FDI; a ratio of inner layers versus total foveal thickness). Patients were followed up until they could perform chart visual acuity (VA) testing. Data were analyzed using linear mixed regression models. Visual acuity predicted by foveal grading was compared with prediction by PL, the current gold standard for visual assessment in infants and young children. MAIN OUTCOME MEASURES: Grade of foveal hypoplasia, quantitative parameters (photoreceptor length, OS length, FDI), and PL VA were obtained in preverbal children for comparison with future chart VA outcomes. RESULTS: We imaged 81 eyes from 42 patients with infantile nystagmus of mean age 19.8 months (range, 0.9-33.4 months; standard deviation [SD], 9.4 months) at the first handheld OCT scan. Mean follow-up was 44.1 months (range, 18.4-63.2 months; SD, 12.0 months). Structural grading was the strongest predictor of future VA (grading: r = 0.80, F = 67.49, P < 0.0001) compared with quantitative measures (FDI: r = 0.74, F = 28.81, P < 0.001; OS length: r = 0.65; F = 7.94, P < 0.008; photoreceptor length: r = 0.65; F = 7.94, P < 0.008). Preferential looking was inferior to VA prediction by foveal grading (PL: r = 0.42, F = 3.12, P < 0.03). CONCLUSIONS: Handheld OCT can predict future VA in infantile nystagmus. Structural grading is a better predictor of future VA than quantitative segmentation and PL testing. Predicting future vision may avert parental anxiety and may optimize childhood development.

PURPOSE: To report anterior segment features in unclassified anterior segment dysgenesis with overlapping features of Axenfeld-Rieger syndrome and other developmental anomalies. METHODS: This retrospective study included those with atypical or overlapping features in one or both eyes, which were identified as unclassified ASD. Typical ARS was defined as the presence of posterior embryotoxon with or without iris changes like stromal hypoplasia, corectopia, polycoria, or ectropion uvea with or without systemic features. Cases of ARS with overlapping features with other ASD, like aniridia (complete or incomplete absence of iris), iridocorneal endothelial (ICE) syndrome (beaten metal appearance of corneal endothelium), Peters anomaly, isolated trabeculodysgenesis (evidenced by Haab's striae, buphthalmos, and epiphora) in one or both eyes with other typical ARS features in the same or other eye were included and screened. RESULTS: Of 56 cases of ARS seen over 10 years, a total of 17 eyes of 11 cases (M:F=9:2, unilateral n=3) with unclassified ASD were identified with a median age of patients of 28.45±17.75 years (range 6-30 years). All cases of unclassified ASD had the presence of focal atypical strands of non-progressive anterior synechiae extending from the iris mid-periphery to the cornea with no attachments to the Schwalbe's line in any case. Adjacent keratic precipitates or pigment were present in three eyes with focal beaten metal appearance in one eye. Three patients developed repeated episodes of anterior uveitis in one eye with stromal involvement seen in all cases, which responded to antiviral therapy. CONCLUSIONS: Atypical features like focal strands with differential corneal involvement and onset of viral uveitis in unclassified ARS suggest a possible viral etiology during different periods of eye development.

Tessier facial clefts are among the rarest facial clefts reported in literature and many contradicting issues have always been rising over the management and surgical approaches involved during the craniofacial cleft repair. Among the craniofacial clefts Tessier no. 4 is an extremely rare facial anomaly, and there are very few evidence which clearly describe the surgical approaches and techniques. Often these type of craniofacial clefts yield very poor surgical results, and they require multidisciplinary sequential corrective surgeries. This article presents a rare case of an 18-month-old baby with bilateral Tessier no. 4 clefts and its successful rehabilitation.

PurposeThe objective of this study is to evaluate and grade the extent and severity of ocular involvement in Tessier number 10 cleft.Patients and methodsA retrospective, noncomparative, interventional case series was conducted between January 2006 and December 2015. Clinical data were reviewed from 59 patients (85 eyes) with Tessier number 10 clefts. Detailed medical history and ophthalmic examination of patients with a confirmed diagnosis of Tessier number 10 cleft were recorded on an itemized data collection form. Ocular manifestations were categorized as upper eyelid defect, symblepharon with cutaneous pterygium (skin growing onto the globe), corneal complications, and lower eyelid ectropion; components were evaluated and graded on a scale from 0 to 3, according to their severity.ResultsMore than half of the cases (43 eyes, 53.8%) had severe upper eyelid defect, and severe symblepharon with cutaneous pterygium were observed in 38 eyes (47.5%). Nearly half of the cases (40 eyes, 50.0%) have severe corneal complications, and lower eyelid ectropion was found in 34 eyes (42.5%). The severity of symblepharon, corneal complications, and lower eyelid ectropion were significantly correlated with the upper eyelid defect; the correlation coefficient (r) ranged from 0.844 to 0.629 (P<0.0001).ConclusionThis study presents the ocular manifestation of Tessier number 10 clefts with large-series cases, and establishes an effective grading system to evaluate Tessier number 10 clefts, which is useful for the diagnosis, treatment, and prediction of outcomes in patients with a Tessier number 10 cleft.

PURPOSE: The purpose of this study was to classify combined persistent fetal vasculature (PFV) on the basis of the ultrasonographic and Doppler characteristics. The potential clinical significance for both surgery design and prognosis determination was discussed. DESIGN: A cross-sectional case series. PARTICIPANTS: The eyes of 54 children diagnosed with unilateral combined PFV were evaluated using B-mode ultrasound and color Doppler imaging (CDI). METHODS: Each participant's age at first presentation, diagnosis for referral, gender, family history, and systemic or other ocular anomalies were recorded. Retinal detachment, optic nerve abnormalities, and macular dislocation were also recorded in detail according to the RetCam (Clarity Medical Systems, Pleasanton, CA), ultrasound, and Doppler findings. The PFV eyes were divided into 4 groups on the basis of the ultrasound and CDI findings. Intergroup analysis was performed. MAIN OUTCOME MEASURES: Overall and intergroup analyses of the demographic features of the children with PFV were performed. The axial length, depth of the anterior chamber, and lens thickness were compared between the affected eyes and the fellow healthy eyes among the 4 groups. RESULTS: Some 22.2%, 18.5%, 33.3%, and 25.9% of the eyes were grouped into type I ("I" shape), II ("Y" shape), III (inverted "Y" shape), and IV ("X" shape) combined PFV, respectively. The age at first presentation for type I was older than that for the other groups (P = 0.014). The axial length was reduced (P = 0.012) and the anterior chamber more shallow (P = 0.011) than in fellow healthy eyes for type IV eyes, but not for the other 3 groups. CONCLUSIONS: Ultrasound and CDI are informative screening and diagnostic tools that show characteristic flow patterns in the 4 types of combined PFV. This novel classification system provides new and important information for the diagnosis of PFV and, if validated, may play a role in guiding treatment recommendations in the future.

Biallelic mutations of UBE3B have recently been shown to cause Kaufman oculocerebrofacial syndrome (also reported as blepharophimosis-ptosis-intellectual disability syndrome), an autosomal recessive condition characterized by hypotonia, developmental delay, intellectual disability, congenital anomalies, characteristic facial dysmorphic features, and low cholesterol levels. To date, six patients with either missense mutations affecting the UBE3B HECT domain or truncating mutations have been described. Here, we report on the identification of homozygous or compound heterozygous UBE3B mutations in six additional patients from five unrelated families using either targeted UBE3B sequencing in individuals with suggestive facial dysmorphic features, or exome sequencing. Our results expand the clinical and mutational spectrum of the UBE3B-related disorder in several ways. First, we have identified UBE3B mutations in individuals who previously received distinct clinical diagnoses: two sibs with Toriello-Carey syndrome as well as the patient reported to have a "new" syndrome by Buntinx and Majewski in 1990. Second, we describe the adult phenotype and clinical variability of the syndrome. Third, we report on the first instance of homozygous missense alterations outside the HECT domain of UBE3B, observed in a patient with mildly dysmorphic facial features. We conclude that UBE3B mutations cause a clinically recognizable and possibly underdiagnosed syndrome characterized by distinct craniofacial features, hypotonia, failure to thrive, eye abnormalities, other congenital malformations, low cholesterol levels, and severe intellectual disability. We review the UBE3B-associated phenotypes, including forms that can mimick Toriello-Carey syndrome, and suggest the single designation "Kaufman oculocerebrofacial syndrome".

OBJECTIVE: To investigate the feasibility of handheld (HH) ultra-high-resolution spectral-domain optical coherence tomography (SD-OCT) in young children with nystagmus, to determine its sensitivity and specificity in classifying foveal abnormalities, and to investigate its potential to determine the cause of infantile nystagmus with the use of foveal morphology. DESIGN: Prospective, case-control study. PARTICIPANTS AND CONTROLS: A total of 50 patients with nystagmus and 50 healthy control subjects (mean age, 3.2 years; range, 0-8 years). METHODS: Each patient was scanned using HH SD-OCT (Bioptigen Inc., Research Triangle Park, NC) without sedation, and foveal morphology was classified into 1 of 4 categories: (1) typical foveal hypoplasia (predicting clinical diagnosis of albinism, PAX6 mutations, or isolated foveal hypoplasia); (2) atypical foveal hypoplasia (predicting achromatopsia); (3) other foveal changes (corresponding to retinal dystrophies); and (4) normal fovea (predicting idiopathic or manifest latent nystagmus). An independent interpretation of the HH SD-OCT scans by masked examiners was performed, and the sensitivity and specificity of the predicted diagnosis were calculated. MAIN OUTCOME MEASURES: The success rate of image acquisition and sensitivity and specificity of the HH SD-OCT in classifying foveal abnormalities. RESULTS: In 94% of examinations, HH SD-OCT was successful. Twenty-three patients had typical foveal hypoplasia (category 1). Of these patients, 21 were diagnosed with albinism and 2 were diagnosed with PAX6 mutations. Five patients were classified as atypical (category 2) and diagnosed with achromatopsia. Six patients had other abnormal foveal morphology (category 3) and were diagnosed with retinal dystrophy. Sixteen patients had normal foveal morphology (category 4). Of these patients, 12 were diagnosed with idiopathic nystagmus and 4 were diagnosed with manifest latent nystagmus. Sensitivities of HH SD-OCT for classifying typical or atypical foveal hypoplasia, other abnormal foveal morphology, and normal morphology were 92.8%, 86.7%, 41.1%, and 88.4%, respectively, with specificities of 91.4%, 94.8%, 97.7% and 95.1%, respectively. CONCLUSIONS: We demonstrate excellent feasibility of HH SD-OCT in the diagnosis of conditions associated with infantile nystagmus. The HH SD-OCT classification of foveal abnormalities was highly sensitive and specific. This classification was used to determine the underlying cause of infantile nystagmus. Handheld SD-OCT in early childhood can facilitate focused investigations and earlier diagnosis. This is important in an era when potentially time-sensitive treatment, such as gene therapy, is imminent.

Frontonasal Dysplasia (FND) and Oculo-auriculo-vertebral spectrum (OAVS) are two well-recognized clinical entities. With features of both FND and OAVS, the term oculoauriculofrontonasal syndrome (OAFNS) was coined in 1981. The OAFNS phenotype combines elements of abnormal morphogenesis of the frontonasal and maxillary process (derived from forebrain neural crest) with abnormal development of the first and second branchial arches (derived from hindbrain neural crest). We present a case series of 33 children with OAFNS ascertained from a comprehensive review of the literature and report an additional retrospective series of eight patients displaying features consistent with OAFNS. Notably, in a subset of our cases, we have observed abnormalities in nasal ossification and bony structures of the maxilla that have not previously described in OAFNS and are not seen in either FND or OAVS. We present the phenotype and novel naso-maxillary findings and explore potential etiologic and developmental pathways for OAFNS. We highlight the differences in phenotypic characteristics of OAFNS compared to OAVS and FND. These observations support the classification of OAFNS as a discrete syndrome. Further phenotypic refinements of OAFNS are needed to understand pathogenesis of this syndrome and the newly described nasal malformation may help identify the etiology.

PURPOSE: To report the varied presentation and management of cryptophthalmos and further categorize grades of the congenital symblepharon variant based on the severity of the defect. METHODS: The records of 34 eyes of 25 patients with cryptophthalmos who sought treatment at the authors' tertiary eye care center over a period of 22 years were analyzed. RESULTS: Of the 34 eyes, 25 belonged to the congenital symblepharon variant, which could distinctively be further classified in medial/mild (4), moderate (9), and severe (11) subgroups and the surgical management for each has been outlined. The associated corneal and facial anomalies have also been highlighted along with their management modalities when indicated. CONCLUSIONS: Although a rare clinical entity, this is the largest series of cryptophthalmos reported so far with a proposed classification scheme for the congenital symblepharon variant.

PURPOSE: To investigate the long-term clinical course and visual outcomes of Peters' anomaly cases treated with various treatment modalities. PATIENTS AND METHODS: All patients with Peters' anomaly treated at Seoul National University Children's Hospital from 1985 to 2005 were reviewed retrospectively. Patients who were followed for more than 5 years after the first visit were enrolled for analysis of the visual outcome. Final visual outcomes were presented with respect to disease severity and treatment modalities. Disease severity was determined according to the corneal status and accompanied eye anomalies in mild or severe form. Treatment plans were classified into the following groups: (1) a medical treatment group; (2) a surgical treatment group; and (3) a no-treatment group. RESULTS: A total of 106 eyes in 76 patients were diagnosed as Peters' anomaly, and 90 eyes in 65 patients were analysed regarding the visual outcome. Overall, 60 eyes (67%) had severe disease, and 30 eyes (33%) had mild disease. Twenty-six eyes (29%) received medical treatment, 44 eyes (49%) received surgical treatment, and 20 eyes (22%) received no treatment. The mean final visual acuity was 1.415 logMAR, 2.344 logMAR, and 2.282 logMAR, respectively. The visual outcomes of the eyes with mild disease in each group were significantly better than the eyes with severe disease. CONCLUSIONS: The long-term visual outcomes of Peters' anomaly differed according to the disease severity in each treatment group. Therefore, before making treatment plans for Peters' anomaly, it is important to investigate the corneal status and accompanying eye disease to determine disease severity.

Oral-Facial-Digital Syndrome type VI (OFD VI) represents a rare phenotypic subtype of Joubert syndrome and related disorders (JSRD). In the original report polydactyly, oral findings, intellectual disability, and absence of the cerebellar vermis at post-mortem characterized the syndrome. Subsequently, the molar tooth sign (MTS) has been found in patients with OFD VI, prompting the inclusion of OFD VI in JSRD. We studied the clinical, neurodevelopmental, neuroimaging, and genetic findings in a cohort of 16 patients with OFD VI. We derived the following inclusion criteria from the literature: 1) MTS and one oral finding and polydactyly, or 2) MTS and more than one typical oral finding. The OFD VI neuroimaging pattern was found to be more severe than in other JSRD subgroups and includes severe hypoplasia of the cerebellar vermis, hypoplastic and dysplastic cerebellar hemispheres, marked enlargement of the posterior fossa, increased retrocerebellar collection of cerebrospinal fluid, abnormal brainstem, and frequently supratentorial abnormalities that occasionally include characteristic hypothalamic hamartomas. Additionally, two new JSRD neuroimaging findings (ascending superior cerebellar peduncles and fused thalami) have been identified. Tongue hamartomas, additional frenula, upper lip notch, and mesoaxial polydactyly are specific findings in OFD VI, while cleft lip/palate and other types of polydactyly of hands and feet are not specific. Involvement of other organs may include ocular findings, particularly colobomas. The majority of the patients have absent motor development and profound cognitive impairment. In OFD VI, normal cognitive functions are possible, but exceptional. Sequencing of known JSRD genes in most patients failed to detect pathogenetic mutations, therefore the genetic basis of OFD VI remains unknown. Compared with other JSRD subgroups, the neurological findings and impairment of motor development and cognitive functions in OFD VI are significantly worse, suggesting a correlation with the more severe neuroimaging findings. Based on the literature and this study we suggest as diagnostic criteria for OFD VI: MTS and one or more of the following: 1) tongue hamartoma(s) and/or additional frenula and/or upper lip notch; 2) mesoaxial polydactyly of one or more hands or feet; 3) hypothalamic hamartoma.

PURPOSE: To investigate the prevalence and clinical features of acquired lower eyelid epiblepharon in Korean patients with thyroid-associated ophthalmopathy (TAO) and compare the pathogenic features of acquired and congenital epiblepharon. DESIGN: Retrospective, nonrandomized, comparative case series, cross-sectional study. PARTICIPANTS: A total of 494 Korean patients with TAO and 845 Korean patients with congenital lower eyelid epiblepharon. METHODS: The medical records were reviewed, and the presence, location, and extent of epiblepharon were identified. Clinical features of TAO (lower eyelid retraction, exophthalmos, and elevation limitation) were compared between patients with TAO with and without epiblepharon. Acquired epiblepharon was classified into 3 types according to the location and extent. The prevalence of epiblepharon types was determined and evaluated for associations with TAO clinical features. Comparisons were made between the prevalence of epiblepharon types in acquired and congenital epiblepharon. MAIN OUTCOME MEASURES: Prevalence, location, and extent of epiblepharon; association with clinical features of TAO; and difference from congenital epiblepharon. RESULTS: An acquired lower eyelid epiblepharon was found in 42 (8.5%) of 494 patients with TAO. The mean age of patients with TAO with epiblepharon (34.2±13.5 years) was significantly lower than that of patients with TAO without epiblepharon (46.5±14.1 years) (P = 0.000). Lower eyelid retraction (0.78±1.11 mm) was more severe in patients with TAO with epiblepharon than in patients without epiblepharon (0.30±0.73 mm) (P = 0.000). Lower eyelid retraction was more severe in diffuse-type acquired epiblepharon than in central-type epiblepharon (P = 0.012). Elevation limitation was more severe in central-type acquired epiblepharon than in medial-type epiblepharon (P = 0.001). The occurrence of central-type epiblepharon was higher in TAO-associated acquired epiblepharon (20 eyelids, 30.8%) than in congenital epiblepharon (27 eyelids, 1.9%, P = 0.000). CONCLUSIONS: Acquired lower eyelid epiblepharon is one of the clinical features of patients with TAO. The association between lower eyelid retraction and acquired epiblepharon may lead to a better understanding of the cause of acquired epiblepharon in patients with TAO.

PURPOSE: To characterize and grade the spectrum of foveal hypoplasia based on different stages of arrested development of the fovea. Grading was performed using morphologic findings obtained by ultra high-resolution spectral-domain optical coherence tomography. Best-corrected visual acuity (BCVA) was calculated for different grades. DESIGN: Observational case series. PARTICIPANTS AND CONTROLS: Sixty-nine patients with foveal hypoplasia (albinism, n = 34; PAX6 mutations, n = 10; isolated cases, n = 14; achromatopsia, n = 11) and 65 control subjects were examined. METHODS: A 7×7-mm retinal area was sampled using a 3-dimensional scanning protocol (743×75, A scans×B scans) with ultra high-resolution spectral-domain optical coherence tomography (SOCT Copernicus HR; 3-µm axial resolution). Gross morphologic abnormalities were documented. B-scans at the fovea were segmented using a longitudinal reflectivity profile. Logarithm of the minimum angle of resolution BCVA was obtained. MAIN OUTCOME MEASURES: Grading was based on presence or absence of foveal pit and widening of the outer nuclear layer (ONL) and outer segment (OS) at the fovea. Quantitative measurements were obtained for comparing atypical foveal hypoplasia in achromatopsia. Best-corrected visual acuity was compared with the grade of foveal hypoplasia. RESULTS: Four grades of foveal hypoplasia were distinguished: grade 1, shallow foveal pit, presence of ONL widening, presence of OS lengthening; grade 2, grade 1 but absence of foveal pit; grade 3, grade 2 but absence of OS lengthening; grade 4, grade 3 but absence of ONL widening. There was significant difference in visual acuity (VA) associated with each grade (P<0.0001). Grade 1 was associated with the best VA (median VA, 0.2), whereas grades 2, 3, and 4 were associated with progressively poorer VA with a median VA of 0.44, 0.60, and 0.78, respectively. The atypical features seen with foveal hypoplasia associated with achromatopsia were characterized by decreased retinal and ONL thickness and deeper foveal depth. CONCLUSIONS: A structural grading system for foveal hypoplasia was developed based on the stage at which foveal development was arrested, which helps to provide a prognostic indicator for VA and is applicable in a range of disorders associated with foveal hypoplasia. Atypical foveal hypoplasia in achromatopsia shows different characteristics.

OBJECTIVE: Because many patients with velocardiofacial syndrome (VCFS) are first examined by otolaryngologists for ear or speech problems before being diagnosed with VCFS, we describe a series of patients with this genetic disorder, which is associated with multiple anomalies, including velopharyngeal insufficiency, cardiac defects, characteristic facial features, and learning disabilities. STUDY DESIGN: We retrospectively analyzed the medical charts and available nasoendoscopic observations for 35 patients who were diagnosed with VCFS and who had a microscopic deletion in chromosome 22q11 as shown by DNA probe and fluorescence in situ hybridization. RESULTS: For most patients, the medical chart documented cardiac anomalies, velopharyngeal insufficiency with hypernasal speech, and characteristic facial features including nasal, auricular, craniofacial, and ocular abnormalities. Incidence of middle ear infection with associated conductive hearing loss was also high and necessitated early placement of pressure equalization tubes. Some patients were treated with adenoidectomy for chronic otitis media; consequently, velopharyngeal insufficiency and hypernasal speech worsened. Nasoendoscopic examination as documented in the medical chart showed occult cleft palate, a small adenoid pad, and pulsation in the muscular wall. CONCLUSION: Otolaryngologists have an important role in diagnosis and treatment of persons with VCFS and therefore should familiarize themselves with the typical history and most frequent head and neck manifestations of this syndrome.

We report on an 8-year-old boy with clinical manifestations suggestive of a new arthrogryposis syndrome. These included characteristic craniofacial abnormalities, cleft palate, arthrogryposis multiplex congenita, pulmonary hypoplasia, cryptorchidism, and unusual ophthalmological findings. There was no intrauterine growth retardation or decreased fetal movements. Despite the poor prognosis expected in early life, the patient presented with normal mental capability on follow-up. Family data showed that a maternal first cousin of the mother (mother's brother's son) had similar findings and died in infancy. Differential diagnosis included Pena-Shokeir syndrome or phenotype, Gordon syndrome, Marden-Walker syndrome, and the syndrome of arthrogryposis with ophthalmoplegia and retinopathy. The possibility of autosomal dominant inheritance with reduced penetrance is suggested for this apparently new syndrome.
