OBJECTIVE
To evaluate the efficacy of spectral-domain optical coherence tomography (SD-OCT) in differentiating optic disc edema (ODE) and optic nerve head drusen (ONHD) and to reveal the differential points.
METHODS
Comparative case series.
METHODS
Forty-five patients with ONHD, 15 patients with
OBJECTIVE
We quantitatively investigated the peripapillary vascular morphology in patients with optic nerve head drusen (ONHD) and optic disc edema (ODE).
METHODS
Computer-based fundus analysis was used to investigate peripapillary vascular morphology, including length, branching, and diameter of
OBJECTIVE
In this study we investigated macular morphology, including individual retinal layers, in patients with optic nerve head drusen (ONHD) and optic disc edema (ODE) compared with healthy participants, using high-resolution spectral domain optical coherence tomography
BACKGROUND
The fluorescein angiographic criteria for differentiating optic disc drusen (ODD) from optic disc edema have been unclear. We designed a study to identify distinguishing angiographic features of each and to apply them to cases where both drusen and edema were present.
METHODS
A computer
In the case report, bilateral cystoid macular edema with optic disc edema on the left side in young man is described. As etiology out of the systemic diseases, we considered the hypertension. The results of the neurological examination, including the brain CT examination were physiological. The
OBJECTIVE
To assess optical coherence tomography in differentiating optic disc edema (ODE) due to papilledema and other optic neuropathies from optic nerve head drusen (ONHD).
METHODS
Optical coherence tomographic images from 60 subjects (20 with ODE, 20 with ONHD, and 20 control subjects) were
BACKGROUND
Sudden visual loss and optic disc edema caused by optic neuritis (ON) is usually followed by significant visual recovery. However, little or no recovery occurs when the loss is caused by atypical ON, especially in patients with neuromyelitis optica (NMO). Optic disc drusen (ODD) is a
OBJECTIVE
Mutations in the MFRP (membrane-type frizzled-related protein) gene leads to an entity characterized by retinitis pigmentosa, nanophthalmos, optic disk drusen, and macular changes, originally described as foveoschisis. Despite the association of MFRP gene mutation and increase in macular
BACKGROUND
To assess the efficacy of quantitative analysis of the optic nerve head and peripapillary retinal nerve fiber layer (RNFL) with the spectral-domain optical coherence tomography (SD-OCT) in differentiating optic disc edema (ODE) from optic nerve head drusen (ONHD).
METHODS
Prospective
An elevated optic nerve head can be an ominous sign, sometimes signifying an underlying basis for raised intracranial pressure. Alternatively, patients may harbor a different mechanism for this optic nerve head appearance, including optic disc drusen (ODD), which does not confer any life-threatening
To evaluate and compare the morphologic characteristics of buried optic disc drusen (ODD) and optic disc edema (ODE) by using en face optical coherence tomography (OCT) and OCT angiography (OCTA) DESIGN: Retrospective, cross-sectional study METHODS: We reviewed the medical records of Optic disc drusen (ODD) are benign congenital anomalies of the optic nerve characterized by calcified hyaline bodies. While superficial drusen can be diagnosed easily during fundus examination, detecting buried drusen requires the use of additional imaging methods such as B-scan ultrasonography
