Q

Describe the formation of aqueous humour

A

CO2 and H2O is made into HCO3 (bicarbonate) and H+ by carbonic anhydrase in PIGMENTED epithelium
HCO3 and H+ are swapped out into blood to bring Cl and Na in
Cl and Na go into non-pigmented epithelium and into posterior chamber

Q

Name the parts of the retinal layer

A

retina, optic disc and macula

17
Q

How does CSF get from two lateral ventricles to 3rd ventricle?

A

Via two inter ventricular foramina

18
Q

Layers of meninges from outer to inner

A

Dura mater, arachnoid mater, pia mater

19
Q

Name the ventricles

A

2x lateral ventricles

3rd ventricle and 4th ventricle

20
Q

What is contained in the anterior segment?

A

Anterior chamber = cornea to iris, contains aqueous humour

Posterior chamber = iris to suspensory ligaments, contains aqueous humour

21
Q

Name the 6 intrinsic muscles of the eye

A 
Superior rectus
Inferior rectus
Medial rectus
Lateral rectus
Superior oblique
Inferior oblique
22
Q

Name the parts of the uvea layer of the eyeball

A

iris, ciliary body, choroid

23
Q

Innervation of superior oblique

A

CNIV, trochlear because of name of pulley

24
Q

Which muscle is innervated by CNVI?

A

Lateral rectus (abducens)

25
Q

What is contained in the posterior segment?

A

Vitreous body and vitreous humour

26
Q

How does CSF get from 3th ventricles to 4rd ventricle?

A

Via the cerebral aqueduct

27
Q

What is the blind spot

A

When light hits the optic disc as there are no photoreceptors

28
Q

What is the macula?

A

Area of retina with greatest density of cones. When focused on an object, the light will be hitting the macula. Seen as the darkest patch on fundoscopy

29
Q

What artery supplies the eye?

A

Opthalmic artery

30
Q

Function of Choroid?

A

Vascular part of uvea layer, for gas exchange and nutrition

31
Q

What side of ciliary body is non-pigmented epithelium on?

A

Apical side - side in contact with humour

32
Q

What is the ion content of CSF like compared to blood?

A

CSF has higher Na, Cl and bicarbonate

33
Q

Describe the flow of aqueous humour

A

Ciliary body to posterior chamber to anterior chamber and drains via Canal of Shlemm

34
Q

What is the arterial supply to the eye

A

Ophthalmic artery that branches to central retinal artery and posterior ciliary arteries
