Ophthalmology- Colloquium 1- 4th Year- PMU

The uvea is the [blank_start]middle[blank_end] coat (layer) of the eye and its parts include: a) [blank_start]Ciliary[blank_end] Body b) [blank_start]Choroid[blank_end] c) [blank_start]Iris[blank_end]

The size of the pupil depends on the contaction and relaxation of [blank_start]sphincter[blank_end] pupillae muscle and [blank_start]dilator[blank_end] pupillae muscle. What is their innervation? [blank_start]Sympathetic[blank_end] and [blank_start]Parasympathetic[blank_end] fibers

What is the refractive power (approximately) of the cornea? Ans: [blank_start]43[blank_end] Dioptres

List down 3 functions of the ciliary body 1) [blank_start]Accommodation[blank_end] 2) [blank_start]Aqueous[blank_end] humor production 3) Lens [blank_start]zonules[blank_end] maintenance

List down the neurons which transport the nerve impulse from the retina to the brain 1) [blank_start]Rods[blank_end] and [blank_start]Cones[blank_end] 2) [blank_start]Bipolar[blank_end] neurons 3) [blank_start]Ganglion[blank_end] cells 4) [blank_start]Optic[blank_end] Nerve

List down extraocular and their innervation 1) [blank_start]Superior[blank_end] rectus muscle- [blank_start]Occulomotor[blank_end] Nerve 2) [blank_start]Inferior[blank_end] rectus muscle- [blank_start]Occulomotor[blank_end] Nerve 3) [blank_start]Lateral[blank_end] rectus muscle- [blank_start]Abducens[blank_end] Nerve 4) [blank_start]Medial[blank_end] rectus muscle- [blank_start]Occulomotor[blank_end] Nerve 5) [blank_start]Superior[blank_end] [blank_start]oblique[blank_end] muscle- [blank_start]Trochlear[blank_end] Nerve 6) [blank_start]Inferior[blank_end] [blank_start]oblique[blank_end] muscle- [blank_start]Occulomotor[blank_end] Nerve

The photoreceptors are [blank_start]Rods[blank_end] and [blank_start]Cones[blank_end]

List down the bones which form the orbit (alphabetical order) 1) [blank_start]Ethmoid[blank_end] bone 2) [blank_start]Frontal[blank_end] bone 3) [blank_start]Lacrimal[blank_end] bone 4) [blank_start]Maxillary[blank_end] bone 5) [blank_start]Palatine[blank_end] bone 6) [blank_start]Sphenoid[blank_end] bone 7) [blank_start]Zygomatic[blank_end] bone

The normal retina colour is [blank_start]white[blank_end]

The optic nerve (II) consists of the axons of the [blank_start]ganglion[blank_end] cells

The ophthalmic artery is a branch of
