Anisometropia

Question 1

“iso” in Greek is?

Answer 1

equal

Question 2

is defined as a condition in which the refractive status of one eye differs from that the other.

Answer 2

Anisometropia

Question 3

A form of anisometropia in which one eye is myopic and the other hyperopic.

Answer 3

Antimetropia

Question 4

The condition in which the refractive status is equal in the two eyes.

Answer 4

Isometropia

Question 5

• The condition in which the two eyes have unequal refractive power. One eye may be myopic (nearsighted) and the other hyperopic (farsighted) or one eye may be markedly stronger than the other.

Answer 5

ANISOMETROPIA or ASYMMETROPIA

Question 6

different amount of the same error of refraction.

Answer 6

ANISOMETROPIA

Question 7

different type of errors such as hyperopia vs. myopia or spherical vs. astigmatic.

Answer 7

Antimetropia

Question 8

this occurs because of differential growth of the eyeball of both eyes. It is hereditary in origin.

Answer 8

Congenital Anisometropia

Question 9

created by trauma, pathology or the results of systemic changes.

Answer 9

Acquired Anisometropia

Question 10

It is a condition in which the refractive power of the two eyes is unequal.

Answer 10

Absolute anisometropia

Question 11

It is that type of refractive anomaly in which although the total refraction of the two eyes is equal, the component elements in each show relatively large differences.

Answer 11

Relative anisometropia

Question 12

Types of Absolute Anisometropia

Answer 12

• Simple
• Compound
• Mixed
• Simple Astigmatic Anisometropia
• Compound Astigmatic Anisometropia
• Mixed Astigmatic Anisometropia

Question 13

In this, one eye is normal and the other is either hypermetropic or myopic.

Answer 13

Simple AA

Question 14

In this, both eyes are ametropic either hyperopic or myopic, but one eye has a higher refractive error.

Answer 14

compound AA

Question 15

In this both eyes are ametropic. One eye is hyperopic and the other is myopic. This is called antimetropia.

Answer 15

mixed AA

Question 16

when one eye is normal and the other has either myopic or hyperopic astigmatism.

Answer 16

Simple Astigmatic Anisometropia

Question 17

when both eyes are astigmatic but of unequal degree.

Answer 17

Compound Astigmatic Anisometropia

Question 18

If there is a difference of more than 5D between the two eyes, the patient loses binocularity.

Answer 18

 Binocular Vision

Question 19

If the anisometropia is high and the eyes have a good visual acuity, the patient gets into the habit of using the hypermetropic eye for distance and the myopic eye for near vision.

Answer 19

 Alternating Vision

Question 20

If the defect in one eye is high and if its visual acuity is not good, the eye can be excluded altogether from vision and the

Answer 20

 Amblyopia

Question 21

A concomitant convergent squint occurs in children with the eye having the defect becoming convergent.

Answer 21

 Strabismus

Question 22

is a serious concern in newborns and young children because it can lead to amblyopia (impaired vision in one eye).

Answer 22

Anisometropia

Question 23

this is commonly referred to as lazy eye.

Answer 23

 Amblyopia

Question 24

this is when a person is not able to align both of their eyes under normal conditions simultaneously and is referred as being cross eyed.

Answer 24

 Strabismus

Question 25

this is when a person has double vision

Answer 25

 Diplopia

Question 26

also known as the Worth’s Four Dot test or W4LT, is a clinical test mainly used for assessing a patient’s degree of “binocular vision” and “binocular single vision”.

Answer 26

Worth Four Light Test

Question 27

A red reflex is when light is transmitted through the transparent portions of the eye and reflects off the retina, creating a reddish orange reflection in the eyes.

Answer 27

iScreen Vision

The various modes of treatment and management are:

Answer 28

	Spectacles
	Contact lenses
	Refractive laser --- LASIK laser
	Phakic IOL
	Clear lens extraction with the implantation of an IOL
