Imaging of the eye and visual system... more than meets the eye!

Radiology of the eye, orbits and visual tracts! Anatomy and the pathology of the visual system, extensively discussed from the globe all the way to the occipital cortex, with attention for both the optic pathways (n. II) and the oculomotor cranial nerves (n. III, IV, VI). This is a detailed (but as a consequence very long) case-based presentation. Nobody has time to watch a radiology presentation of over 2 hours, so use the time stamps to jump to a part of anatomy or pathology that interests you, or look up the separate shorter presentations on this channel in which anatomy and pathology are discussed for each orbital compartment separately. 0:00 - Introduction 0:32 - Indications for orbital imaging 2:54 - Visual field deficits 10:11 - Orbital compartmental anatomy 12:32 - Anatomy & Pathology of the bony orbit 12:38 - Anatomy of the bony orbit 18:17 - Tumors of the bony orbit 28:30 - Orbital fractures 35:44 - Anatomy & Pathology of the globe 36:02 - Antomy of the eye ball 43:46 - Incidental imaging findings 49:14 - Coloboma and staphyloma 51:29 - Retinal detachment 53:07 - Choroid detachment 55:14 - Uveal metastases 56:29 - Uveal melanoma 57:35 - Retinoblastoma 1:01:11 - Anatomy & Pathology of the conal space 1:01:34 - Anatomy of the extra-ocular muscles 1:06:44 - Thyroid eye disease 1:19:24 - Idiopathic orbital inflammation (orbital pseudotumor) 1:25:28 - Orbital lymphoma 1:28:17 - Anatomy & Pathology of the intraconal space 1:28:56 - Anatomy of the optic nerve 1:33:14 - Optic nerve sheath meningioma 1:37:20 - Optic glioma 1:39:24 - Optic neuritis 1:44:27 - Orbital venous malformation (aka "cavernous hemangioma) 1:47:31 - Orbital venolymphatic malformation 1:49:47 - Orbital varix 1:52:59 - Orbital metastases 1:55:01 - Anatomy & Pathology of the extraconal space 1:55:35 - Anatomy of the extraconal space 2:01:25 - Orbital infection 2:08:00 - Orbital pseudotumor (inflammation) 2:09:38 - Dermoid cyst 2:12:21 - Lacrimal gland lesions 2:15:26 - Anatomy & Pathology of the optic pathways & cranial nerves (III, IV, VI) 2:17:08 - Optic vs. oculomotor pathyway anatomy & pathology 2:19:02 - Simplified anatomy of the oculomotor pathways 2:20:31 - Caroticocavernous fistula 2:23:22 - Cavernous ICA & pCom aneurysms 2:26:00 - Tolosa Hunt syndrome 2:28:21 - Anatomy of the optic chiasm 2:28:59 - Sellar tumors with optic chiasm compression 2:29:25 - Optic tract infarction 2:30:41 - Occipital ischemic infarction 2:31:44 - Occipital lobe tumor 02:32:00 - Key Messages This video is brought to you by the neuroradiologist:   / theneuroradguy     / the_neurora.  . https://theneuroradiologist.org/ #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #MRI #CT #medical #eyes #mri #radiologytechnologist #radiologyresident #brainanatomy #ophthalmology #orbit
