B Correct answer
Explanation

LASIK (Laser-Assisted In Situ Keratomileusis) surgery is a common refractive surgery procedure used to correct nearsightedness, astigmatism, and farsightedness.

Multiple choice

What is the term for the condition in which the macula, the central part of the retina, deteriorates, leading to loss of central vision?

  1. Cataract

  2. Glaucoma

  3. Macular degeneration

  4. Astigmatism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Macular degeneration is a leading cause of vision loss in older adults, affecting the central vision and making it difficult to perform everyday tasks.

What is the term for the condition in which the eye's ability to focus on objects at different distances is impaired?

  1. Cataract

  2. Glaucoma

  3. Presbyopia

  4. Astigmatism
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Presbyopia is an age-related condition in which the eye's ability to focus on nearby objects gradually decreases, making it difficult to read, work on a computer, or perform other close-up tasks.

  4. Medication
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vision therapy is a common treatment for strabismus, involving exercises and activities designed to improve eye coordination and alignment.

Multiple choice

What is the term for the condition in which the retina detaches from the back of the eye, leading to vision loss?

  1. Cataract

  2. Glaucoma

  3. Retinal detachment

  4. Macular degeneration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Retinal detachment is a serious eye condition in which the retina separates from the underlying layers of the eye, causing vision loss and requiring immediate medical attention.

  1. Cataract

  2. Glaucoma

  3. Keratitis

  4. Macular degeneration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Keratitis is an inflammation of the cornea, often caused by infection, injury, or autoimmune disorders, leading to pain, redness, and blurred vision.

Multiple choice

Which of the following is a common cause of acute angle-closure glaucoma?

  1. Dilated pupils

  2. Narrow anterior chamber angle

  3. Increased intraocular pressure

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Acute angle-closure glaucoma occurs when the iris blocks the flow of fluid from the anterior chamber, leading to a rapid increase in intraocular pressure. Dilated pupils, narrow anterior chamber angle, and increased intraocular pressure are all contributing factors.

Multiple choice

What is the primary goal of treatment for acute angle-closure glaucoma?

  1. Reduce intraocular pressure

  2. Dilate the pupil

  3. Constrict the pupil

  4. Perform laser iridotomy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The immediate goal in treating acute angle-closure glaucoma is to reduce intraocular pressure as quickly as possible to prevent permanent vision loss. This can be achieved through medications, laser therapy, or surgery.

Multiple choice

What is the most common cause of retinal detachment?

  1. Posterior vitreous detachment

  2. Lattice degeneration

  3. Retinal tears

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Posterior vitreous detachment, lattice degeneration, and retinal tears are all risk factors for retinal detachment. Posterior vitreous detachment is the most common cause, occurring when the vitreous gel separates from the retina.
