NCLEX_ Glaucoma (Eye Disorders) Quiz Questions and Answers

• Which statement below is CORRECT about glaucoma?

• “The vision loss that occurs with glaucoma is reversible with eye drop

medications.”

• “Glaucoma occurs due to decreased intraocular pressure, which damages the

optic nerve.”

• “Surgery can cure glaucoma.”

• “A normal intraocular pressure is about 10-21 mmHg and is elevated in

most patients with glaucoma.”

The answer is D. This option is the only correct statement about glaucoma. Vision loss is NOT reversible when it occurs in glaucoma but it’s permanent…eye drops can prevent further progression. Glaucoma occurs due to INCREASED intraocular pressure (NOT decreased), and there is NO cure for glaucoma.

• A patient asks you to explain how the intraocular pressure is measured to

help detect glaucoma. You state that IOP (intraocular pressure) is measured by what instrument below?

• Goniscope

• Tonometry

• Ophthalmoscope

• Phoroptor

The answer is B. A tonometer is used to assessment IOP.

• The production and drainage rate of aqueous humor is not equal in patients

with glaucoma. Select below the correct sequence for how aqueous humor

should flow through the eye:

• The ciliary body produces aqueous humor -> then it flows through the

anterior chamber (area of the eye between the iris and cornea) -> pupil opening -> posterior chamber (area of the eye between lens and iris) ->drainage angle - >trabecular meshwork -> schlemm’s canal -> episcleral veins

• The lens produces aqueous humor -> then it flows through the pupil opening

-> the anterior chamber (area of the eye between the iris and cornea) ->

posterior chamber (area of the eye between lens and iris) -> drainage angle - >trabecular meshwork -> schlemm’s canal -> episcleral veins

• The ciliary body produces aqueous humor -> then it flows through the

posterior chamber (area of the eye between the lens and iris) -> pupil opening -> anterior chamber (area of the eye between iris and cornea) -> drainage angle ->trabecular meshwork -> schlemm’s canal -> episcleral veins

• The lens produces aqueous humor -> then it flows through the posterior

chamber (area of the eye between the iris and cornea) -> pupil opening -> anterior chamber (area of the eye between lens and iris) -> drainage angle - >trabecular meshwork -> schlemm’s canal -> episcleral veins

The answer is C. This is the correct sequence for how aqueous humor flows

through the eye: The ciliary body produces aqueous humor -> then it flows

through the posterior chamber (area of the eye between the lens and iris) -> pupil opening -> anterior chamber (area of the eye between iris and cornea) -> drainage angle ->trabecular meshwork -> schlemm’s canal -> episcleral veins

• You’re providing an educational seminar to a group of senior citizens about

glaucoma. You explain to the participants about the differences between open-angle and angle-closure glaucoma in relation to the drainage angle of the eye. A participant asks what type of examination can be performed to assess the drainage angle of the eye. Your response is?

• Tonometry

• Ophthalmoscopy

• Retinoscopy

• Gonioscopy
