ONH drusen

PURPOSE: To examine the ophthalmic data from a large database of people attending a general medical survey institute, and to investigate ophthalmic findings of the eye and its adnexa, including differences in age and sex. METHODS: Retrospective analysis including medical data of all consecutive individuals whose ophthalmic data and the prevalences of ocular pathologies were extracted from a very large database of subjects examined at a single general medical survey institute...

PURPOSE: To determine the characteristics of peripapillary hyperreflective ovoid mass-like structures (PHOMS) in patients with nonarteritic anterior ischemic optic neuropathy (NAION) and in normal adults. METHODS: A total of 406 included eyes were divided into four groups: acute NAION group, chronic NAION group, unaffected group, and normal eyes group. PHOMS were detected on optical coherence tomography slices from optical coherence tomography angiography scans centered on the optic nerve head (ONH)...

Optic nerve head (ONH) drusen are acellular calcified concretions. Buried drusen manifests as pseudopapilledema. The compressive effects of ONH drusen can rarely precipitate central retinal vein occlusion (CRVO). The superimposition of pseudopapilledema on disc edema in CRVO poses a diagnostic dilemma. A 40-year-old female without systemic comorbidities presented with resolving CRVO. An exhaustive systemic workup revealed no abnormalities. Ultrasonography demonstrated buried ONH drusen. This unusual etiology must be considered in a young patient in the absence of systemic risk factors, persistence of "nasally conspicuous" disc elevation, and presence of peripapillary hemorrhages...

Optic nerve head (ONH) edema is a clinical manifestation of many ocular and systemic disorders. Ocular and central nervous system imaging has been used to differentiate the underlying cause of ONH edema and monitor the disease course. ONH vessel abnormalities are among the earliest signs of impaired axonal transportation. Optical coherence tomography angiography (OCTA) is a noninvasive method for imaging ONH and peripapillary vessels and has been used extensively for studying vascular changes in ONH disorders, including ONH edema...

PURPOSE: To investigate the prevalence of optic disc drusen (ODD) and optic nerve head (ONH) morphology in patients diagnosed with normal tension glaucoma (NTG). METHODS: In this prospective cross-sectional study, we included patients diagnosed with NTG from two glaucoma units. In both eyes, dense enhanced depth imaging optical coherence tomography volume scans of the ONH by means of standardized scanning guidelines were performed to examine for presence of ODD, and radial ONH scans were used for investigating parameters such as scleral canal diameter, cup/disc ratio and cup depth...

Peripapillary hyperreflective ovoid mass-like structures (PHOMS) are a laterally bulging herniation of distended axons into the peripapillary region above the level of Bruch's membrane opening. Increased use of enhanced depth imaging-optical coherence tomography (EDI-OCT) in our evaluation of the optic nerve head (ONH) and greater recognition of the vast range of optic nerve pathologies with which PHOMS is associated provides convincing evidence that PHOMS is not just buried optic disc drusen (ODD) as previously described...

BACKGROUND AND OBJECTIVES: The distinction of papilledema from other optic nerve head (ONH) lesions mimicking papilledema, such as optic disc drusen (ODD), can be difficult in clinical practice. We aimed: (1) To develop a deep learning algorithm to automatically identify major structures of the optic nerve head (ONH) in three dimensional (3D) optical coherence tomography (OCT) scans; (2) To exploit such information to robustly differentiate among ODD, papilledema, and healthy ONHs. METHODS: This was a cross-sectional comparative study of patients from three sites (Singapore, Denmark, Australia) with confirmed ODD, papilledema due to raised intracranial pressure, and healthy controls...

BACKGROUND: Membrane frizzled-related protein (MFRP) plays a critical role in ocular development. MFRP mutations are known to cause nanophthalmos and, in some cases, retinitis pigmentosa, foveoschisis, and/or optic nerve head (ONH) drusen. The broad clinical spectrum of MFRP mutations necessitates further investigation of specific genotype-phenotype relationships. MATERIALS AND METHODS: We reviewed ophthalmologic and genetic medical records of two affected siblings and one unaffected sibling...

Visual field defects are common in patients with optic disc drusen (ODD). Our aim was to examine whether reduced optic nerve head (ONH) microcirculation is related to visual field defects in ODD patients. Vascular and tissue area mean blur rate (MBRV and MBRT ), measured using laser speckle flowgraphy (LSFG), was significantly lower in the 32 included ODD eyes when compared with 40 healthy eyes ( p <.05). There was a moderate correlation between the difference in MBRT and the perimetric mean defect (R2  = 0...

BACKGROUND: To analyse structural characteristics and perifoveal/peripapillary vasculature by OCT in children with peripapillary hyperreflective ovoid mass-like structures (PHOMS) and compare the results with those of normal subjects. METHODS: Forty-five patients (84 eyes) under 18 years old with blurry disc margin were evaluated with spectral domain-OCT and swept course-OCT. Patients were divided into four groups, according to presence of PHOMS and then the size of the existing PHOMS...

BACKGROUND: Distinguishing optic disc edema from pseudopapilledema is a common, sometimes challenging clinical problem. Advances in spectral-domain optical coherence tomography (SD-OCT) of the optic nerve head (ONH) has proven to be a cost effective, noninvasive, outpatient procedure that may help. At its core are tools that quantify the thickness of the retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GC-IPL). The SD-OCT also provides a set of tools that may be qualitatively interpreted in the same way that we read an MRI...

PURPOSE: To examine optic nerve head (ONH) anatomy in young adults with central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO) or nonarteritic anterior ischemic optic neuropathy (NA-AION) in order to look for associated, potentially predisposing anomalies. METHODS: Cross-sectional study including 54 patients (ages 16-50 years) diagnosed from 2009 to 2018 with CRVO, BRVO, CRAO, BRAO, or NA-AION...

AIMS: This study aimed to investigate morphologic features of optic disc drusen (ODD) and peripapillary hyperreflective ovoid mass-like structures (PHOMS) in children, using enhanced depth imaging optical coherence tomography (EDI-OCT). It also assessed if the presence of these features were associated with decreased peripapillary retinal nerve fibre layer (RNFL) thickness. METHODS: Retrospective observational study of children with ODD. All subjects underwent complete ophthalmic examination and multimodal imaging...

Purpose: To report the association of optic nerve head (ONH) drusen with Best vitelliform macular dystrophy (BVMD). Methods: Chart review. Patients: Five patients from 3 families. Results: Multimodal imaging and ophthalmic examination demonstrated findings consistent with ONH drusen, in association with BVMD, in 5 patients. Conclusion: We report the association of BVMD with ONH drusen in 5 patients...

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...

DESIGN: Prospective, cross-sectional, observational study. PARTICIPANTS: Total of 130 clinically normal subjects. METHODS: Serial horizontal and vertical EDI OCT B-scans (interval between scans, ∼30 μm) of the optic nerve head (ONH) were obtained in both eyes of clinically normal subjects...

PURPOSE: To evaluate the incidence of visual field defects and choroidal neovascular membranes (CNVM) in a cohort of pediatric patients with optic nerve head drusen (ONHD). METHODS: The medical records of children with ONHD seen at a single center from January 2012 to July 2014 were retrospectively reviewed to identify patients who had a dilated fundus examination, fundus photography, spectral domain optical coherence tomography (SD-OCT)/enhanced-depth imaging (EDI) of the optic nerve head (ONH), SITA fast 24-2 Humphrey visual field (HVF) testing, lumbar puncture, and ocular ultrasound...

PURPOSE: To investigate changes of inner retinal layers and optic nerve head (ONH) in patients with dry age-related macular degeneration (AMD) and demonstrate the pattern of these changes. METHODS: A total of 76 eyes classified as having dry AMD and 76 control eyes were included. Ophthalmologic evaluations included best-corrected visual acuity (BCVA) assessment, spectral-domain optical coherence tomography (SD-OCT), and Humphrey visual field (VF) test. The drusen area and volume were determined using the automated algorithm of the SD-OCT software...

PURPOSE: To describe a case of bilateral optic nerve head drusen (ONHD) in a pediatric patient and the complementary use of advanced noninvasive imaging techniques to confirm this diagnosis. CASE REPORT: A 15-year-old female adolescent with type 1 diabetes and no ocular history was seen at a routine screening without complaints. Visual acuity was 20/20 bilaterally, and visual fields using frequency doubling technology (Zeiss Humphrey Systems, Dublin, CA) were within normal limits...

PURPOSE: To evaluate optic nerve head (ONH) parameters, peripapillary retinal nerve fiber layer (RNFL) thickness, and macular thickness by using Cirrus HD spectral-domain optical coherence tomography (OCT) in young patients with retinitis pigmentosa (RP). METHODS: ONH parameters, RNFL thickness, and macular thickness were measured and compared between 36 eyes from 36 young RP patients (RP group; mean age, 23.08 years) and 70 eyes from 70 healthy young subjects (control group; mean age, 22...
