Accepted Answer

The statement is true. The extraocular muscles are responsible for moving the eyes and are attached to the eyeball and the orbit.

Question 2

The white of the eye is the alba.

Accepted Answer

The white of the eye is called the sclera, not the alba.

Question 3

Dryness and inflammation of the cornea and conjunctiva caused by inadequate tear production is called photophobia.

Accepted Answer

Dryness and inflammation of the cornea and conjunctiva caused by inadequate tear production is actually called dry eye syndrome, not photophobia. Photophobia refers to a sensitivity to light that causes discomfort and sometimes pain in the eyes.

Question 4

The process of producing tears is termed lacrimation.

Accepted Answer

Lacrimation is the process of producing tears from the lacrimal glands.

Question 5

The function of blinking is termed palpitation.

Accepted Answer

Palpitation refers to rapid or irregular heartbeat. Blinking is the rapid closing and opening of the eyelids to moisturize the eyes and protect them from foreign particles.

Question 6

Dacry/o and blephar/o are combining forms for the same structure.

Accepted Answer

Dacry/o refers to the tear or tear duct, while blephar/o pertains to the eyelid; thus, they refer to different structures.

Question 7

A turning inward of one or both eyes is called esotropia.

Accepted Answer

Esotropia is a type of strabismus where one or both eyes turn inward, towards the nose.

Question 8

A condition of no lens is aphakia.

Accepted Answer

Aphakia is defined as the absence or loss of the lens in the eye.

Question 9

A swelling of the eyelid is termed blepharitis.

Accepted Answer

Blepharitis is an inflammation of the eyelid margins, not a swelling of the eyelid. Swelling of the eyelid is typically referred to as edema or could be due to a stye or chalazion.

Question 10

The sclera is part of the hard outer covering of the eye.

Accepted Answer

The sclera is also known as the white of the eye and forms the majority of the outer covering of the eye.

Question 11

The bending of light is termed accommodation.

Accepted Answer

The bending of light is actually called refraction. Accommodation is the process by which the lens of the eye changes shape to focus on objects at different distances.

Question 12

Normal vision is termed amblyopia.

Accepted Answer

Amblyopia is actually commonly known as "lazy eye" and refers to a condition where the brain favors one eye and ignores input from the other, leading to reduced vision in that eye. Normal vision would not be classified as amblyopia.

Question 13

Blepharochalasis refers to hypertrophy of the eyelid.

Accepted Answer

Blepharochalasis refers to a condition characterized by recurrent episodes of eyelid swelling and inflammation that ultimately lead to thinning and stretching of the eyelid skin. This can result in a droopy or baggy appearance of the eyelid, but it does not involve hypertrophy (growth) of the eyelid tissue.

Question 14

Patients with an inflammation of the cornea have keratitis.

Accepted Answer

Keratitis is an inflammation of the cornea.

Question 15

Accepted Answer

The lacrimal glands secrete tears, not oil. The Meibomian glands, located in the eyelids, secrete oil onto the eyelashes.

Question 16

Loss of half of the visual field is termed anisocoria.

Accepted Answer

Anisocoria refers to unequal pupils, not loss of visual field.

Question 17

The eyelids are lined with a thin mucous membrane called the conjunctiva.

Accepted Answer

The statement is true. The conjunctiva is a thin, transparent layer of tissue that lines the inner surface of the eyelids and covers the white part of the eye (sclera).

Question 18

The area within the macula lutea that provides the sharpest image is the optic disk.

Accepted Answer

The area within the macula lutea that provides the sharpest image is actually the fovea centralis. The optic disk is the area where the optic nerve exits the eye and does not provide a sharp image.

Question 19

Accepted Answer

Dacryocystitis is indeed the term used to describe inflammation of the lacrimal sac.
