Blutgefäße des Auges

The video tutorial provides an in-depth look at the anatomy and blood supply of the eye, focusing on the ophthalmic artery and its branches, including the ciliary arteries. It explains the venous outflow system and discusses retinal vascular occlusion, highlighting its causes, symptoms, and the urgency of treatment.

What is the primary function of the eye?

• To convert chemical signals into neural impulses

• To convert light rays into neural impulses

• To convert mechanical signals into neural impulses

• To convert sound waves into neural impulses

Where is the visual cortex located?

• In the temporal lobe of the cerebrum

• In the parietal lobe of the cerebrum

• In the occipital lobe of the cerebrum

• In the frontal lobe of the cerebrum

Which artery is the main source of blood supply to the eye?

• The carotid artery

• The ciliary artery

• The ophthalmic artery

• The central retinal artery

What does the central retinal artery primarily supply?

• The optic nerve

• The inner retinal layer

• The outer retinal layer

• The sclera

What is the role of the anterior ciliary artery?

• To supply the optic nerve

• To supply the vitreous body

• To supply the outer retinal layer

• To supply the straight eye muscles

What is the circulus arteriosus iritis major?

• A network of veins in the eye

• A ring of arteries surrounding the iris

• A type of retinal neuron

• A part of the optic nerve

What is the main function of vortex veins?

• To supply blood to the retina

• To drain blood from the eye

• To supply blood to the optic nerve

• To drain blood from the brain

What is a characteristic feature of central artery occlusion?

• The retina turns pale whitish

• The retina turns bright red

• The retina turns blue

• The retina turns green

What is the leading symptom of central artery occlusion?

• Sudden, painless vision loss

• Sudden, painful vision loss

• Gradual, painful vision loss

• Gradual, painless vision loss

What is the most common cause of central artery occlusion?

• An embolus from the carotid arteries or heart

• A local thrombus in the retina

• A viral infection

• A spasm of the retinal vessels
