Questions and Answers

1.

What is the simplest form of treatment for this defect?
- A.
  
  Surgery
- B.
  
  Sun glasses
- C.
  
  Medications
- D.
  
  Corrective lens
Correct Answer
D. Corrective lens

Explanation
The simplest form of treatment for this defect is the use of corrective lenses. Corrective lenses are specifically designed to correct vision problems such as nearsightedness, farsightedness, and astigmatism. They work by bending the light entering the eyes in a way that helps focus it properly on the retina, thus improving vision. Unlike surgery, which may involve more complex procedures and potential risks, corrective lenses provide a non-invasive and easily accessible solution for vision correction. Sun glasses and medications may have their own benefits but are not specifically designed to treat vision defects.

2.

What kind of lens is used to correct this condition?
- A.
  
  Diverging lens
- B.
  
  Myopic lens
- C.
  
  Plane lens
- D.
  
  Convex lens
Correct Answer
D. Convex lens

Explanation
A convex lens is used to correct the condition described in the question. This is because a convex lens is thicker in the middle and thinner at the edges, causing light rays to converge after passing through the lens. This helps to correct myopia, a condition where the eye is unable to focus on distant objects. By using a convex lens, the light rays entering the eye are bent in a way that allows them to focus properly on the retina, resulting in clearer vision for individuals with myopia.

How many types of surgical procedures can be used to treat this condition?
- A.
  
  Three types
- B.
  
  Five types
- C.
  
  Four types
- D.
  
  Six types
Correct Answer
B. Five types

Explanation
The correct answer is "Five types." This suggests that there are multiple surgical procedures available to treat the given condition, specifically five different types.

4.

Which of these can be used to make a diagnosis of the condition?
- A.
  
  Kaleidoscope
- B.
  
  Microscope
- C.
  
  Retinoscope
- D.
  
  Venier caliper
Correct Answer
C. Retinoscope

Explanation
A retinoscope can be used to make a diagnosis of the condition. A retinoscope is an instrument used by eye care professionals to objectively determine a person's eyeglass prescription. It is used to measure the refractive error of the eye, which helps in diagnosing conditions such as nearsightedness, farsightedness, and astigmatism. By shining a light into the eye and observing the reflection, the retinoscope allows the eye care professional to determine the focus of the eye and prescribe the appropriate corrective lenses.

5.

Which of these is not a sign or symptom of hypermetropia?
- A.
  
  Blurry vision
- B.
  
  Eye strain
- C.
  
  Fatigue
- D.
  
  Head ache
Correct Answer
C. Fatigue

Explanation
Fatigue is not a sign or symptom of hypermetropia. Hypermetropia, also known as farsightedness, is a refractive error where distant objects are seen more clearly than close objects. The common signs and symptoms of hypermetropia include blurry vision, eye strain, and headaches. However, fatigue is not directly associated with hypermetropia and may be caused by other factors such as lack of sleep or excessive physical or mental exertion.

6.

Which of these is not examined to diagnose hypermetropia?
- A.
  
  Cornea
- B.
  
  Iris
- C.
  
  Retina
- D.
  
  Eyelid
Correct Answer
D. Eyelid

Explanation
Hypermetropia, also known as farsightedness, is a refractive error where distant objects are seen more clearly than nearby objects. It occurs when the eyeball is shorter than normal or when the cornea is too flat. To diagnose hypermetropia, the cornea, iris, and retina are examined. The cornea's shape and curvature are assessed, the iris is observed for any abnormalities, and the retina is checked for any signs of hypermetropia. However, the eyelid is not examined to diagnose hypermetropia as it does not play a direct role in the condition.

Which of these can be employed to discover the abnormal structures in hypertropia?
- A.
  
  Snellen charts
- B.
  
  Ancillary tests
- C.
  
  Lamp tests
- D.
  
  Physical tests
Correct Answer
B. Ancillary tests

Explanation
Ancillary tests can be employed to discover the abnormal structures in hypertropia. Ancillary tests refer to additional diagnostic tests that can be used to gather more information about a condition. In the case of hypertropia, ancillary tests such as imaging studies (e.g., MRI or CT scan) or electrophysiological tests (e.g., electroretinography) can help identify any abnormal structures or underlying causes contributing to the condition. These tests provide valuable information to aid in the diagnosis and management of hypertropia.

How many categories of hypermetropia are known in medicine?
- A.
  
  Three
- B.
  
  Four
- C.
  
  Five
- D.
  
  Six
Correct Answer
A. Three

Explanation
There are three categories of hypermetropia known in medicine. Hypermetropia, also known as farsightedness, is a refractive error where distant objects can be seen more clearly than near objects. The three categories of hypermetropia are low hypermetropia, moderate hypermetropia, and high hypermetropia. These categories are based on the severity of the condition and the degree of refractive error.

Which of these is not a clinical category of hypermetropia?
- A.
  
  Functional hypermetropia
- B.
  
  Simple hypermetropia
- C.
  
  Traumatic hypermetropia
- D.
  
  Pathological hypermetropia
Correct Answer
C. Traumatic hypermetropia

Explanation
Traumatic hypermetropia is not a clinical category of hypermetropia. Hypermetropia, also known as farsightedness, is a refractive error where distant objects are seen more clearly than near objects. The other three options mentioned are clinical categories of hypermetropia. Functional hypermetropia refers to a temporary condition where the eye is unable to focus properly due to excessive strain or fatigue. Simple hypermetropia is a common type of hypermetropia where the eye is shorter than normal, causing light to focus behind the retina. Pathological hypermetropia is a more severe form of hypermetropia caused by underlying eye conditions or diseases.

Which of these is not a type of refractive error?
- A.
  
  Presbyopia
- B.
  
  Astigmatism
- C.
  
  Cataract
- D.
  
  Near-sightedness
Correct Answer
C. Cataract

Explanation
Cataract is not a type of refractive error. Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina, causing blurred vision. Presbyopia is a condition where the eye gradually loses its ability to focus on nearby objects. Astigmatism is a condition where the cornea or lens is not evenly curved, causing distorted or blurred vision. Near-sightedness, also known as myopia, is a condition where distant objects appear blurry. Cataract, on the other hand, is the clouding of the eye's lens, leading to blurry or hazy vision.
