1*maximum cones r seen in
a)limbus
b)fovea
c)macula
d)blindspot

2*sup oblique muscle is supplied by
a)3rd cranial nerve
b)4th
c)5th
d)6th

3*axial length of eye ball
a)16mm
b)20
c)24
d)28

4*1mm change in axial lenght of eyeball produce change in refractive index by
a)1d
b)2d
c)3d
4)4d

5*blindspot of mariotte is also known as
optic disc
ora serrata
macula
fovea

6*depth of anterior chamber of eye
2-3mm
3-4mm
4-5mm
5-6mm

7*if lenght of eyeball increases by 1mm.the net effect will be
myopia of 6d
hypermetropia of 6d
myopia of 3d
hy[ermetropia of 3d

8*eye structure with maximum refractive power:

6.5
7.0
7.5

10*power of normal eye
+6d
+10d
+16d
+60d

11*isochromatic charts are used for :
contrast sensitivity

visual acuity testing

12*in direct opthalmoscopy,image is magnified by :
5 times
10 times
15 times
20 times

13*initial monoeuver done in congenital dacyocystitis:
probing
massaging
ointments
observation

14*most reliable provocative test for angle closure glaucoma
water drinking test
mydriatic-miotic test
homatropine mydriatic test
dark room test

15*true regarding retinoscpy except:
help in estimatethe condition of refraction
usually performed at 1m distance
consist of a plane and a concave mirror
hyperopes display an against movement

ribavirin
vidarabine

18*pilocarpine used in all except:
primary open agle glaucoma
malignant glaucoma
acute angle closure glaucoma
chr synechial angle close glaucoma

19*drug can be used topically in eye
