Automatic Segmentation of the Optic Nerve Head Region in Optical Coherence Tomography: A Methodological Review [PDF]
arXiv, 2021 The optic nerve head represents the intraocular section of the optic nerve (ONH), which is prone to damage by intraocular pressure. The advent of optical coherence tomography (OCT) has enabled the evaluation of novel optic nerve head parameters, namely the depth and curvature of the lamina cribrosa (LC).

Imaging of adult ocular and orbital pathology - a pictorial review [PDF]
, 2014 Orbital pathology often presents a diagnostic challenge to the reporting radiologist. The aetiology is protean, and clinical input is therefore often necessary to narrow the differential diagnosis.

Case Reports in Ophthalmological Medicine, 2015 Optic disc drusen (ODD) are calcific deposits that form in the optic nerve head secondary to abnormalities in axonal metabolism and degeneration. Anterior ischemic optic neuropathy, central retinal artery, and vein occlusion are among the rare vascular ...

A comprehensive survey on computer-aided diagnostic systems in diabetic retinopathy screening [PDF]
, 2022 Diabetes Mellitus (DM) can lead to significant microvasculature disruptions that eventually causes diabetic retinopathy (DR), or complications in the eye due to diabetes. If left unchecked, this disease can increase over time and eventually cause complete vision loss.

Evaluation of retinal nerve fiber layer thickness in a patient with bilateral optic disc drusen
Revista Brasileira de Oftalmologia, 2015 Optic disc drusen (ODD) is the accumulations of calcified hyaline-like material within the substance of the optic nerve head. Optic disc drusen, especially if it is bilateral, may mimic the clinical presentation of papilledema.

Congenital anomalies of the optic nerve [PDF]
, 2015 Congenital optic nerve head anomalies are a group of structural malformations of the optic nerve head and surrounding tissues, which may cause congenital visual impairment and blindness. Each entity in this group of optic nerve anomalies has individually

The Role of Optical Coherence Tomography Angiography in Optic Nerve Head Edema: A Narrative Review
Journal of Ophthalmology, 2022 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.
