What Are The Causes Of Hypermetropia? - Quiz

Hypermetropia is a serious visual defect characterized by the inability of affected individuals to see near objects clearly. Such individuals can only see distant objects well. Hypermetropia can eventually lead to blindness if symptoms persist. Here, we want to test your knowledge about this condition. Are you in the know?

Questions and Answers

1.

Which of these is not one of the characteristics of hypermetropia?
- A.
  
  Accommodative dysfunction
- B.
  
  Binocular dysfunction
- C.
  
  Astigmatism
- D.
  
  Amblyopia
Correct Answer
C. Astigmatism

Explanation
Astigmatism is not one of the characteristics of hypermetropia. Hypermetropia, also known as farsightedness, is a condition where distant objects are seen more clearly than close objects. The other three options, accommodative dysfunction, binocular dysfunction, and amblyopia, are all associated with hypermetropia. Accommodative dysfunction refers to difficulty in focusing on near objects, binocular dysfunction refers to problems with the coordination of the eyes, and amblyopia refers to reduced vision in one eye.

2.

What medical speciality is concerned with this?
- A.
  
  Oncology
- B.
  
  Neurology
- C.
  
  Nephrology
- D.
  
  Ophthalmology
Correct Answer
D. OpHthalmology

Explanation
Ophthalmology is the correct answer because it is the medical specialty concerned with the diagnosis and treatment of eye disorders and diseases. It focuses on the prevention, diagnosis, and management of conditions affecting the eyes and visual system. Oncology deals with cancer, neurology deals with disorders of the nervous system, and nephrology deals with kidney diseases, none of which are directly related to the eyes.

3.

Which of these is a risk factor for the condition?
- A.
  
  Diabetes
- B.
  
  Alcoholism
- C.
  
  Family history
- D.
  
  Smoking
Correct Answer
C. Family history

Explanation
Family history is a risk factor for the condition because certain diseases and conditions can be passed down through generations. If a person has a family member who has been diagnosed with a particular condition, such as diabetes or cancer, they may be at a higher risk of developing the same condition. This is due to a combination of genetic factors and shared environmental factors within the family. Therefore, having a family history of a certain condition increases the likelihood of developing that condition.

4.

How can this condition be diagnosed?
- A.
  
  Blood tests
- B.
  
  Eye exam
- C.
  
  Neurological exam
- D.
  
  Liver function tests
Correct Answer
B. Eye exam

Explanation
Eye exams can help diagnose various conditions related to the eyes, such as glaucoma, cataracts, or macular degeneration. They involve a series of tests to evaluate the health of the eyes, including visual acuity, eye pressure measurement, and examination of the retina and optic nerve. By assessing the overall condition of the eyes, an eye exam can provide valuable information about a person's ocular health and potentially detect any abnormalities or underlying conditions that may be causing symptoms. Therefore, an eye exam is a suitable diagnostic method for determining the condition mentioned in the question.

5.

What part of the eye is affected in this condition?
- A.
  
  Cones
- B.
  
  Cornea
- C.
  
  Eyelid
- D.
  
  Retina
Correct Answer
D. Retina

Explanation
The condition mentioned in the question refers to an issue with a specific part of the eye. The retina is the part of the eye that is responsible for converting light into electrical signals that the brain can interpret. Therefore, if the question asks which part of the eye is affected in this condition, the correct answer would be the retina.

6.

Which of these can not be employed to treat hypermetropia?
- A.
  
  Surgery
- B.
  
  Massage
- C.
  
  Contact lens
- D.
  
  Eye glasses
Correct Answer
B. Massage

Explanation
Massage cannot be employed to treat hypermetropia because hypermetropia is a refractive error where the eye is unable to focus on nearby objects. Massage does not correct the underlying issue of the eye's inability to focus properly. Surgery, contact lenses, and eyeglasses, on the other hand, can help correct hypermetropia by either reshaping the cornea or providing additional focusing power to the eye.

What percentage of people suffer from this condition in the USA as of 2018?
- A.
  
  7.5 percent
- B.
  
  7.9 percent
- C.
  
  10.8 percent
- D.
  
  9.5 percent
Correct Answer
A. 7.5 percent

Explanation
The correct answer is 7.5 percent. This means that out of the total population in the USA as of 2018, 7.5 percent of people suffer from this condition.

8.

Which of these is not related to the condition?
- A.
  
  Retinitis pigmentosa sine pigmento
- B.
  
  Amblyopia
- C.
  
  Steven-Johnson syndrome
- D.
  
  Retrobulbar optic neuropathy
Correct Answer
C. Steven-Johnson syndrome

Explanation
Steven-Johnson syndrome is not related to the condition because it is a severe skin reaction that can be caused by certain medications or infections. It affects the skin and mucous membranes, causing painful blisters and sores. On the other hand, the other three options are all related to eye conditions. Retinitis pigmentosa sine pigmento is a form of retinitis pigmentosa that does not involve pigmentation changes in the retina. Amblyopia, also known as lazy eye, is a vision development disorder. Retrobulbar optic neuropathy is a condition that affects the optic nerve behind the eye.

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

Explanation
Hypermetropia, also known as farsightedness, is a refractive error where distant objects are seen clearly, but close objects appear blurry. It occurs when the eyeball is shorter than normal or when the cornea is too flat. The correct answer, muscle fatigue, is not a sign of hypermetropia. Muscle fatigue typically occurs due to prolonged use of the eye muscles, such as when reading or using digital devices for extended periods. It is more commonly associated with other vision conditions like astigmatism or presbyopia.

Which of these is not a defect of vision?
- A.
  
  Parkinson's
- B.
  
  Astigmatism
- C.
  
  Presbyopia
- D.
  
  Myopia
Correct Answer
A. Parkinson's

Explanation
Parkinson's is not a defect of vision. It is a neurodegenerative disorder that affects movement and coordination. Astigmatism, presbyopia, and myopia are all defects of vision. Astigmatism is a condition where the cornea or lens of the eye is irregularly shaped, causing blurred or distorted vision. Presbyopia is a condition that occurs with age, where the lens of the eye loses its flexibility, making it difficult to focus on close objects. Myopia, also known as nearsightedness, is a condition where distant objects appear blurry.
