PURPOSE: To report optical coherence tomography (OCT) findings of cherry-red spots from Tay-Sachs and Niemann-Pick disease. METHODS: Consecutive patients with Tay-Sachs and Niemann-Pick disease evaluated by the pediatric transplant and cellular therapy team, for whom a handheld OCT scan was obtained, were included. Demographic information, clinical history, fundus photography, and OCT scans were reviewed. Two masked graders evaluated each of the scans. RESULTS: The study included 3 patients with Tay-Sachs disease (5, 8, and 14 months old) and 1 patient with Niemann-Pick disease (12 months old). All patients had bilateral cherry-red spots on fundus examination. In all patients with Tay-Sachs disease, handheld OCT revealed parafoveal ganglion cell layer (GCL) thickening, increased nerve fiber layer, and GCL reflectivity, and different levels of residual normal signal GCL. The patient with Niemann-Pick disease had similar parafoveal findings, but there was a thicker residual GCL. Sedated visual evoked potentials were unrecordable in all 4 patients despite 3 of them demonstrating normal visual behavior for age. Patients with good vision had relative sparing of the GCL on OCT. CONCLUSIONS: The cherry-red spots in lysosomal storage diseases appear as perifoveal thickening and hyperreflectivity of the GCL on OCT. In this case series, residual GCL with normal signal proved to be a better biomarker for visual function than visual evoked potentials and could be considered for future therapeutic trials.

BACKGROUND/AIMS: The optic nerve development during the critical postnatal weeks of preterm infants is unclear. We aimed to investigate the change of retinal nerve fibre layer (RNFL) in preterm infants. METHODS: We used an investigational handheld optical coherence tomography (OCT) system to serially image awake preterm infants between 30 and 60 weeks postmenstrual age (PMA) at the bedside. We assessed RNFL thickness in the papillomacular bundle and nasal macular ganglion cell layer+inner plexiform layer (GCL+IPL) thickness. We applied a segmented mixed model to analyse the change in the thickness of RNFL and GCL+IPL as a function of PMA. RESULTS: From 631 OCT imaging sessions of 101 infants (201 eyes), RNFL thickness followed a biphasic model between 30 and 60 weeks, with an estimated transition at 37.8 weeks PMA (95% CI: 37.0 to 38.6). RNFL thickness increased at 1.8 µm/week (95% CI: 1.6 to 2.1) before 37.8 weeks and decreased at -0.3 µm/week (95% CI: -0.5 to -0.2) afterwards. GCL+IPL thickness followed a similar biphasic model, in which the thickness increased at 2.9 µm/week (95% CI: 2.5 to 3.2) before 39.5 weeks PMA (95% CI: 38.8 to 40.1) and then decreased at -0.8 µm/week (95% CI: -0.9 to -0.6). CONCLUSION: We demonstrate the feasibility of monitoring RNFL and GCL+IPL thickness from OCT during the postnatal weeks of preterm infants. Thicknesses follow a biphasic model with a transition age at 37.8 and 39.5 weeks PMA, respectively. These findings may shed light on optic nerve development in preterm infants and assist future study designs.
ABSTRACT
PURPOSE: To examine the structural changes occurring in the optic nerve head (ONH) and macula in infants with childhood glaucoma and clinically observed ONH cupping reversal following intraocular pressure (IOP)-reducing glaucoma surgery, as captured by intra-operative spectral-domain optical coherence tomography (SD-OCT). DESIGN: Retrospective observational case series from an ongoing prospective cohort study. METHODS: Included were 18 eyes of 14 patients with childhood glaucoma. All eyes had SD-OCT imaging pre- and post-glaucoma intervention and clinically identified ONH cupping reversal. Patients with poor quality images or persistent optic nerve swelling following IOP reduction were excluded. Outcome measurements included IOP, cup-to-disc ratio, axial length and SD-OCT measurements of the peripapillary retinal nerve fiber layer (pRNFL), transverse horizontal diameter of Bruch membrane opening (BMO-D), cup depth, and macula. RESULTS: Mean age at surgery was 1.14±0.93 years and mean interval between pre- and post-operative imaging was 127 days (range 35-595). Following intervention, mean IOP reduction was 45%, accompanied by significant reductions in the cup-to-disc ratio (0.30±0.12, p<0.001), axial length (0.43±0.28mm, p<0.001) and cup depth (46%, p<0.001). Mean global pRNFL thickness pre- vs. post-treatment was 93.1±14.7µm vs. 93.1±17.1µm, respectively, p=1.0. There was no significant difference in pre- and post-treatment global or sectoral pRNFL, 3mm macular total and segmented retinal layer volumes, or the BMO-D. CONCLUSIONS: Clinical ONH cupping reversal after IOP-lowering surgery was associated with axial length reduction and decrease in cup depth, but no significant change in the pRNFL or macular volume measures. ONH cupping reversal likely marks stabilization but any pre-intervention ONH damage persists.

BACKGROUND: Giant cell arteritis (GCA) is an important diagnostic consideration in elderly patients with vision changes. Superficial temporal artery biopsy (TAB) has long been considered the gold standard diagnostic approach for GCA, but MRI has gained interest as an alternative diagnostic modality. Although most of the literature has focused on imaging abnormalities of branches of the external carotid artery, there have been a few reports of GCA-related inflammatory involvement of the orbit and internal carotid arteries (ICAs) on MRI. METHODS: This was a retrospective cross-sectional study of patients undergoing TAB at a single tertiary referral center over a 5-year period. Patients who had undergone contrast-enhanced MRI of the brain and orbits within 1 month of biopsy were included. Fifty-four TAB-positive and 78 TAB-negative patients were reviewed, with the MRI studies of 7 TAB-positive and 6 TAB-negative patients deemed adequate for interpretation. MRI studies were reviewed by 2 masked neuroradiologists, and the findings were correlated with biopsy results and clinical findings. RESULTS: Intracranial ICA vessel wall enhancement was identified in 6 of 7 TAB-positive patients (sensitivity 86%), compared with 2 of 6 TAB-negative patients (specificity 67%). Optic nerve sheath enhancement was identified in 5 of 7 TAB-positive patients (sensitivity 71%) and in 2 of 6 TAB-negative patients (specificity 67%), bilateral in all such cases. The combination of both abnormal imaging findings was observed in 5 of 7 TAB-positive patients (sensitivity 71%) and in none of the 6 TAB-negative patients (specificity 100%). CONCLUSIONS: Intracranial ICA and optic nerve sheath enhancement were observed in a majority of patients with TAB-proven GCA, and the combination of these findings was highly specific for GCA. Identification of these abnormalities on MRI should raise concern for GCA and prompt a thorough review of systems, laboratory testing, and consideration of TAB in patients with ocular complaints potentially consistent with ischemia.

PURPOSE: To assess retinal nerve fiber layer (RNFL) thickness in preterm infants. DESIGN: Prospective observational study. METHODS: We imaged 83 awake infants (159 eyes) at 36 ± 1 weeks postmenstrual age (defined as the time elapsed between the first day of the last maternal menstrual period and the time at imaging) using a handheld optical coherence tomography (OCT) system at the bedside. Blinded graders semi-automatically segmented RNFL in the papillomacular bundle (-15 to +15° relative to the fovea-optic nerve axis). We correlated RNFL thickness and 7 characteristics of interest (sex, race, ethnicity, gestational age, birth weight, stage of retinopathy at prematurity, and presence of pre-plus or plus disease) via univariable and multivariable regressions. RESULTS: RNFL was 3.4 µm thicker in the right eyes than in the left eyes (P < .001). Among 7 characteristics, birth weight was the only independent predictor of RNFL thickness (P < .001). A 250-g increase in birth weight was associated with 5.2 µm (95% confidence interval: 3.3-7.0) increase in RNFL thickness. Compared with very preterm infants, extremely preterm infants had thinner RNFL (58.0 ± 10.7 µm vs 63.4 ± 10.7 µm, P = .03), but the statistical significance disappeared after adjustment for birth weight (P = .25). RNFL thickness was 11.2 µm thinner in extremely low birth weight infants than in very low birth weight infants (55.5 ± 8.3 µm vs. 66.7 ± 10.2 µm; P < .001). The difference remained statistically significant after adjustment for gestational age. CONCLUSION: Birth weight is a significant independent predictor of RNFL thickness near birth, implying that the retinal ganglion cells reserve is affected by intrauterine processes that affect birth weight.

PRéCIS:: Overhead mounted spectral-domain optical coherence tomography (OCT) enables high-quality imaging of the optic nerve and macula in childhood glaucoma, and is particularly useful when standard tabletop OCT has failed or is not possible. PURPOSE: Tabletop OCT, integral to adult glaucoma management, can be limited in childhood glaucoma patients because of young age, poor cooperation, and/or technical challenges. To address these imaging difficulties, we determined the feasibility and quality of an overhead mounted unit in childhood glaucoma. Secondary aims included evaluation of peripapillary retinal nerve fiber layer (pRNFL), parafoveal total retinal thickness, and parafoveal ganglion cell complex (GCC) thickness. MATERIALS AND METHODS: Children and adults with a diagnosis of childhood glaucoma were imaged with an overhead mounted spectral-domain OCT as part of a prospective cross-sectional study. Participants had poor quality or unobtainable tabletop OCT and were scheduled for an examination under anesthesia and/or surgery as part of standard care. RESULTS: A total of 88 affected eyes in 60 of 65 (92.3%) enrolled patients (mean age, 5.9±5.9 y; range, 0.2 to 24.5) were successfully imaged. The mean image quality for analyzed scans was 22.9±6.0 dB (n=236 images). Mean values for pRNFL (80.5±31.0 µm; n=86), parafoveal total retinal thickness (301.10±39.9 µm; n=79), and parafoveal GCC thickness (96.0±21.6 µm; n=74) were calculated. CONCLUSIONS: Overhead mounted OCT allowed high-quality image acquisition and analysis in childhood glaucoma patients unable to be imaged with the tabletop counterpart, presenting an opportunity for improved clinical management and study of childhood glaucoma-related pathophysiology. pRNFL, parafoveal total retinal thickness, and parafoveal GCC thickness were decreased for affected eyes of children under 6 years of age compared with age-matched controls from a companion normative study.

PURPOSE: To determine the natural history and visual outcomes of papilledema in cerebral venous sinus thrombosis (CVST). DESIGN: Retrospective observational case series. METHODS: This multicenter study included 7 tertiary care neuro-ophthalmology clinics. Sixty-five patients with CVST were identified who received serial eye examinations with documented papilledema from 2008-2016. Outcome measures included time from diagnosis to papilledema documentation, papilledema progression, time to papilledema resolution, treatment interventions and final visual outcomes. RESULTS: Papilledema was present on initial presentation in 54% of patients or detected later during the course of the disease in 46% of patients. The average time from CVST diagnosis to papilledema documentation was 29 days with a mean (SD) initial Frisén grade of 2.7 (1.3). In 21.5% of cases, papilledema progressed over an average of 55.6 (56.6) days. Time to papilledema resolution was approximately 6 months. Final visual acuity ranged from 20/20 to light perception, with 40% of patients having residual visual field defects on standard automated perimetry. Frisén grade ≥3 (odds ratio [OR] 10.21, P < .0053) and cases with worsening papilledema (3.5, P < .043) were associated with permanent visual field deficits. CONCLUSIONS: Our study indicates the importance of serial ophthalmic evaluation in all cases of CVST. Follow-up fundoscopy is critical given that a subset of cases can show delayed onset and/or worsening of papilledema with time. Specifically, we recommend an ophthalmic examination at the time of initial diagnosis, with repeat examination within a few weeks and further follow-up depending on the level of papilledema or vision changes.

PURPOSE: Compared with fluorescein angiography (FA), the gold standard for diagnosing choroidal neovascularization (CNV) activity, optical coherence tomography angiography (OCTA) is non-invasive without risks associated with fluorescein dye use, and may be especially advantageous in the diagnosis and monitoring of children with CNV. METHODS: Eight eyes from eight patients aged 12 months to 18 years were imaged with the investigational Spectralis OCTA (version 6.9, Heidelberg Engineering, Heidelberg, Germany) and the RTVue XR Avanti (Optovue Inc., Fremont, CA, USA). Two patients were imaged during examination under anesthesia while six patients were imaged in the clinic. Demographic information, ocular characteristics, treatment history, and imaging studies (color photos, fluorescein angiography, OCT) were collected and reviewed. RESULTS: Three eyes had active CNV while five had quiescent CNV at the time of imaging. CNV was idiopathic or secondary to trauma, retinal vascular dysgenesis versus retinopathy of prematurity, pigmentary retinopathy, Best vitelliform macular dystrophy, panuveitis, morning glory disc anomaly, and optic disc drusen. OCTA of two active CNV demonstrated presence of a main trunk with multiple fine capillaries, vessel loops, and anastomoses. OCTA was repeated after treatment for two CNV and demonstrated a decrease in size with loss of fine capillaries, vessel loops, and anastomoses. For the third active CNV, OCTA verified flow in the CNV complex despite the uncertainty of FA hyperfluorescence in the setting of grossly abnormal retinal vasculature. The five quiescent CNV all lacked fine capillaries, vessel loops, and anastomoses on OCTA. CONCLUSION: OCTA demonstrates morphological differences between active and quiescent pediatric CNV.

PURPOSE: To assess macular vasculature in healthy infants and children using OCT angiography (OCTA). DESIGN: Prospective cross-sectional study. PARTICIPANTS: One hundred thirty-five normal maculae of 89 healthy infants and children (mean age, 8.5±5.3 years; range, 9 weeks-17 years) treated at the Duke University Eye Center. METHODS: We imaged 135 maculae of 89 pediatric patients using the standard Spectralis tabletop and investigational Spectralis with Flex module devices, both equipped with investigational OCTA software (Heidelberg Engineering, Heidelberg, Germany). OCT angiography images of the superficial vascular complex (SVC) and deep vascular complex (DVC) were analyzed for foveal avascular zone (FAZ) area and superficial and deep vessel density. We assessed effects of age, gender, race, axial length (AL), and central subfield thickness on FAZ and vessel density. Patients with both eyes imaged were assessed for agreement between the FAZ and vessel densities of the left and right eyes. MAIN OUTCOME MEASURES: The FAZ area, as well as vessel area density (VAD) and vessel length density (VLD) in the SVC and DVC. RESULTS: The FAZ varied significantly with race; white patients showed a significantly smaller FAZ than black patients (mean difference, 0.11 mm2; P = 0.004). The FAZ did not vary with age, gender, or AL (P > 0.05). In the SVC, VAD and VLD varied significantly with age (P < 0.001) and AL (R2 = 0.46; P < 0.001) but not gender (P > 0.05). The SVC VLD was significantly different between races and ethnicities (P = 0.037), but VAD was not (P < 0.05). In the DVC, VAD and VLD also varied significantly with age (P < 0.001) and AL (R2 = 0.46; P < 0.001) but not gender or race (P > 0.05). There was excellent agreement between the right and left eyes for FAZ (intraclass correlation [ICC], 0.97), SVC VLD (ICC, 1.00), and DVC VLD (ICC, 1.00). CONCLUSIONS: Quantitative studies of pediatric perifoveal vasculature should consider age, race, and AL. In eyes with unilateral disease, the perifoveal vasculature in the unaffected eye may be used as a control comparison because there is excellent agreement between eyes.

PURPOSE: To determine reference values for the peripapillary retinal nerve fiber layer (pRNFL) and macula in children 0-5 years of age. DESIGN: Prospective cross-sectional study. METHODS: This study was set in a single large academic pediatric ophthalmology practice. Healthy, full-term children 0 to <6 years of age presenting for surgery under general anesthesia were prospectively recruited for participation. Excluded were children with systemic neurologic disease, optic nerve or retinal disease (even if unilateral) or any bilateral ocular disease process, and eyes with amblyopia, ocular disease, or spherical equivalent refractive error outside of -3.00 to +8.00 diopters. Following general anesthesia, OCT scans of the optic nerve and retina were acquired using an HRA+OCT Spectralis with Flex module (Heidelberg Engineering). Automated segmentation of the pRNFL and retinal layers was followed by manual correction. RESULTS: Data were obtained from normal eyes of 57 participants (mean age 2.28 ± 1.50 years). Mean global pRNFL thickness was 107.6 ± 10.3 µm. Mean global pRNFL thickness was not dependent on age but showed a negative relationship with axial length (P = .01). The mean total macular volume was 8.56 ± 0.259 mm3 (n = 38). No relationship was found between total macular volume and age. Ganglion cell layer, ganglion cell complex, and inner nuclear layer volumes showed an inverse relationship with age while the photoreceptor layers showed a logarithmic increase with age. CONCLUSIONS: Global pRNFL thickness measurements remain stable over time. Macular volume and thickness values of segmented retinal layers reflect the development of the macula with age.

PURPOSE: Measurements of the ganglion cell complex (GCC), comprising the retinal nerve fiber (RNFL), ganglion cell, and inner plexiform layers, can be correlated with vision loss caused by optic nerve disease. Handheld optical coherence tomography (HH-OCT) can be used with sedation in children who are not amenable to traditional imaging. We report GCC and RNFL measurements in normal children using HH-OCT. DESIGN: Prospective observational study of normal children ≤5 years of age. METHODS: Healthy, full-term children ≤5 years of age undergoing sedation or anesthesia were enrolled. Exclusion criteria included prematurity and pre-existing neurologic, genetic, metabolic, or intraocular pathology. Demographic data, axial length (Master-Vu Sonomed Escalon, Lake Success, New York, USA), and HH-OCT macular and optic nerve volume scans at 0° (Bioptigen, Inc., Morrisville, North Carolina, USA) were obtained. Retinal segmentation was completed with DOCTRAP software, creating average volume thickness maps. RESULTS: Sixty-seven children (67 eyes, 31 males ranging in age from 3.4-70.9 months) were enrolled. Average axial length was 21.2 ± 1.0 mm with mean spherical equivalent +1.49 ± 1.34 diopters (range -2.25 to 4.25). Average GCC volume for the total retina was 0.28 ± 0.04 mm3. Forty-seven of these eyes had RNFL analysis. Average RNFL thickness of the papillomacular bundle was 38.2 ± 9.5 µm. There was no correlation between GCC volume, RNFL thickness, patient age, or axial length. CONCLUSION: Average GCC volume and RNFL thickness was stable from 6 months to 5 years of age. This study provides normative data for GCC and RNFL obtained by HH-OCT in healthy eyes of young children, to serve in evaluating those with optic neuropathies.

An investigational, portable spectral-domain optical coherence tomography (SD-OCT) unit revealed small hyperreflective opacities in both eyes of a patient with bilateral retinoblastoma. There was no evidence of vitreous seeding on ophthalmoscopy of either eye. Although the opacities may initially raise concern for potential vitreous seeding, this report suggests alternate potential etiologies for such opacities, which were also seen on imaging of a cohort of normal eyes in pediatric patients.

PURPOSE: To explore vitreoretinal pathologies and their longitudinal changes visible on handheld optical coherence tomography (OCT) of young children with familial exudative vitreoretinopathy. METHODS: The authors retrospectively analyzed handheld OCT images for vitreoretinal interface and retinal abnormalities and optic nerve head (ONH) elevation. RESULTS: From 26 eyes of 16 children (mean age 32 months) with familial exudative vitreoretinopathy, 10 had ONH dragging on photographs, and in these, handheld OCT revealed temporal and anterior retinal displacement, prominent vitreopapillary adhesion or traction, and retinal nerve fiber layer thickening at ONH margins with adjacent retinal elevation. Despite a nearly normal photographic appearance, handheld OCT revealed ONH elevation with vitreopapillary traction (6/16 eyes), ONH edema (1/16 eye), and retinal vascular protrusion (5/16 eyes). Handheld OCT-visualized vitreous abnormalities (18/26 eyes) were more prevalent at higher stages of disease. Handheld OCT-visualized elevation of ONH and the retina worsened over time in nine eyes and improved in 5/6 eyes after vitrectomy. CONCLUSION: Handheld OCT can detect early ONH, retinal, and vitreous changes in eyes with familial exudative vitreoretinopathy. Contraction of strongly adherent vitreous in young patients with familial exudative vitreoretinopathy appears to cause characteristic ONH dragging and tractional complications without partial posterior vitreous detachment. Vitreopapillary dragging may be visible only on OCT and may progress in the absence of obvious retinal change on conventional examination.

PURPOSE: To determine whether the diameter of Bruch's membrane opening (BMO) can distinguish mild papilledema from pseudopapilledema using optical coherence tomography (OCT). METHODS: The medical records of pediatric patients with pseudopapilledma due to optic nerve head (ONH) drusen, patients with papilledema, and normal control subjects were retrospectively reviewed. All eyes underwent OCT imaging of the BMO and retinal nerve fiber layer (RNFL). Transverse horizontal diameter of the BMO and papillary height were measured. Mean BMO, papillary height, and RNFL were compared and receiver operating characteristic (ROC) curves were used to calculate the area under the curve (AUC) and determine BMO and RNFL cut-offs for papilledema and pseudopapilledema. RESULTS: A total of 90 eyes of 90 subjects were included: 58 with pseudopapilledema, 19 with papilledema, and 13 controls. In eyes with papilledema, mean BMO, papillary height, and RNFL decreased as papilledema resolved (1893.8 vs 1582.2 [P = 0.0003], 193.0 vs 108.9 [P < 0.0001], 893.3 vs 695.5 [P = 0.0007], resp.). Eyes with mild papilledema had greater mean BMO and RNFL than those with pseudopapilledema and controls (1893.8 vs 1541.9 vs 1628.8 [P < 0.0001, P = 0.0265] and 193.0 vs 108.7 vs 104.1 [P < 0.0001, P < 0.0001], resp.). Papillary height in mild papilledema was similar to pseudopapilledema but greater than controls (893.3 vs 863.2 vs 593.5 [P = 0.47 and P = 0.0001], resp.). ROC showed good diagnostic discrimination for BMO (AUC = 0.81; 95% CI, 0.70-0.92) and RNFL (AUC = 0.96; 95% CI, 0.93-1.0) in distinguishing mild papilledema from pseudopapilledema. CONCLUSIONS: The horizontal transverse diameter of BMO is enlarged in eyes with mild papilledema and narrows as papilledema resolves. BMO and RNFL can be used together to help distinguish mild papilledema from pseudopapilledema in children.
