07. An increase in refractive index of lens will cause

A. Myopia✓
B. Hypermetropia
C. Astigmatism
D. Presbyopia

08. An increase in radius of curvature of the cornea cause

A. Myopia
B. Hypermetropia✓
C. Astigmatism
D. Presbyopia

Remember, curvature will decrease when the radius of curvature is increased. Increase in curvature cause myopia and increase in radius of curvature cause hypermetropia

09. Anterior displacement of the lens cause

A. Myopia✓
B. Hypermetropia
C. Astigmatism
D. Presbyopia

10. In pathological myopia optic disc appears

A. Large✓
B. Small
C. Same size
D. Any of the above

11. Power of +/- 0.25 cross cylinder is


A. +0.25DSp/-0.25Dcyl
B. +0.50DSp/-0.25Dcyl
C. +0.25DSp/-0.50Dcyl✓
D. None of the above
  • +0.25DSp/-0.50Dcyl or -0.25DSp/+0.50Dcyl is the power of +/-0.25 cross cylinder Similarly,
  • +0.50DSp/-1.00Dcyl or -0.50DSp/+1.00Dcyl is the power of +/-0.5 cross cylinder

12. In cross cylinder, the handle is attached ______ degrees to the power.

A. 180°
B. 90°
C.45°✓
D. None

13. the angle subtended by an object on the nodal point of the reduced eye is known as

A. Angle alpha
B. Angle Kappa
C. Angle gamma
D. Visual angle✓

14. At what distance distant direct ophthalmoscopy is performed?

A. Close to face
B. 20-25 cm✓
C. 1m
D. 6m

15. When a cycloplegic retinoscopy has been performed using cycloplentolate, how many dioptres should be deducted to compensate the ciliary tone?


A. 1.00D
B. 0.75D✓
C. 0.50D
D. 0.00D

1 D for atropine, 0.75 D for cyclopentolate, 0.5 D for homatropine.

16. Duochrome test is based on

A. Spherical aberration
B. Chromatic aberration✓
C. Both
D. None

17. In duochrome test, slightly myopic patient see letters in _____ sharper.

A. Red✓
B. Green
C. Both clear
D. Both blurred

18. Which of the following is not a cycloplegic drug

A. atropine
B. cyclopentolate
C. homatropine
D. Pilocarpine✓

19. While performing retinoscopy with dilated pupil, if central and peripheral shadow seen. It is important to neutralize which shadow?

A. Central✓
B. Peripheral
C. Both
D. None

20. If the horizontal meridian is more curved than the vertical meridian, the astigmatism is

A. With the rule
B. Against the rule✓
C. Oblique astigmatism
D. Bioblique astigmatism

With-the-astigmatism- the vertical meridian is more curved than the horizontal. Against-the-rule astigmatism- the horizontal meridian is more curved than vertical. Oblique astigmatism- the two principal meridia are not the horizontal and vertical though these are at right angles to one another (e.g., 45° and 135°). Bioblique astigmatism- the two principal meridia are not at right angle to each other, e.g., one may be at 30° and the other at 100°.

21. 1% difference in Retinal image size occur if the power difference between two eyes is

A. 0.5 D✓
B. 1 D
C. 2 D
D. 5 D

0.5 D difference between the refractive power of eye cause 1% difference in Retinal image size. Upto 5% difference is well tolerated by brain. Diplopia can occur if Retinal image size difference is more than 5%. That's why anisometropia of more than 2.5 D is important.

22. If the refractive error in both eyes are equal, the condition is known as

A. Emmetropia
B. Anisometropia
C. Isometropia✓
D. Orthophoria

23. If the images projected to the visual cortex from the two retinae are abnormally unequal in size and shape, condition is known as

A. Anisocoria
B. Anisometropia
C. aniseikonia✓
D. heterochromia
  • Anisocoria- difference in pupil size
  • Anisometropia- difference in power
  • Aniseikonia- difference in size and shape of retinal image
  • Heterochromia- difference in iris colour

24. When plane mirror retinoscopy is performed at a distance of 1 m (no cycloplegics used); in myopia less than 1D, the movement of reflex will be

A. With movement✓
B. Against movement
C. No movement
D. No reflex

With movement corresponds to hypermetropia, emmetropia and myopia less than 1D Against movement is seen in myopia more than 1D No movement in case of myopia of 1 D

25. While doing retinoscopy, If the distance between patient and examiner is decreased, the distance correction needed will

A. Increase✓
B. Decrease
C. Remains same
D. Become zero

Distance correction= 1/distance in meter. If distance is 1m, correction needed is 1/1= 1D And if distance is 2/3m correction needed will be 3/2= 1.5 D.
