Which of the following statement for cup disc ratio (CDR) is wrong?
Vertical cup disc ratio is considered more relevant than the horizontal cup disc ratio
Cup disc ratio is increased in glaucoma
Increased cup disc ratio confirms glaucoma
Cup disc ratio may increase with glaucoma progression
Which of the following method you would prefer for optic disc evaluation?
Direct ophthalmoscopy
Indirect ophthalmoscopy
Slit lamp biomicroscopy
Assessing sterophotograph of optic disc
Indicate your slit lamp settings during biomicroscopic evaluation of the retinal nerve fiber layer?
High magnification
High illumination
Red free filter
All of the above
Which of the following sign is most indicative of glaucomatous optic neuropathy?
Abnormal branching pattern of optic disc vessels
Deep optic cup
Prominent dots on the surface of the lamina cribrosa
Localized excavation of the neuroretinal rim
What is the diopteric power of the non-contact Hruby lens?
-70 D
+70 D
-55 D
+55 D
Which is the correct direction for holding a 90D lens during slit lamp biomicroscopy?
The plane side of the lens should be towards the examiner
The convex side of the lens should be towards the examiner
The concave side of the lens should be towards the examiner
There is no correct side for holding the lens; either side can face the examiner
Compared to a +60D lens, a +90D lens has
More magnification and increased field of view
Less magnification and increased field of view
Less magnification and decreased field of view
More magnification and decreased field of view
Which of the following statement regarding beta peripapillary atrophy is wrong?
Present in glaucomatous as well as in non-glaucomatous eyes
Large choroidal vessels become visible
Larger beta zone often has thin neuroretinal rim in the same area
Progression of beta zone is associated with glaucoma progression
The magnification provided by a +78 D lens is:
0.77
1.1
1.3
1.5
Which of the following statement regarding Disc Damage Likelihood Scale is wrong?
Patient’s optic disc diameter must be taken into account
Has 10 stages
Generates a cup/disc ratio
Is developed by Dr. George Spaeth
