Q. 1

Painless loss of vision is seen in all, EXCEPT:

 A

Papilledema

 B

Papillitis

 C

Angle closure glaucoma

 D

CRAO

Ans. C

Explanation:

Acute angle-closure glaucoma is an ophthalmic emergency that causes severe visual loss without treatment. Symptoms include ocular pain, blurred vision, lacrimation, halos around lights, frontal headache, nausea, and vomiting.

Causes of Sudden Painless Loss of Vision:

  1. Retinal detachment
  2. Vitreous haemorrhage
  3. Retinal vein occlusion
  4. Retinal artery occlusion
  5. Wet age related macular degeneration
  6. Anterior ischemic optic neuropathy
  7. Optic neuritis
  8. Cerebrovascular accident
  9. Papillitis
  10. Papilledema

Q. 2

Sudden loss of vision is seen in following, except:

 A

CRAO

 B

CRVO

 C

Optic neuritis

 D

Papilledema

Q. 2

Sudden loss of vision is seen in following, except:

 A

CRAO

 B

CRVO

 C

Optic neuritis

 D

Papilledema

Ans. D

Explanation:

Papilledema (choked disk) is usually a symptom of increased intracranial pressure caused by a mass, such as a brain tumor. The increased pressure is transmitted to the optic disk through the extension of the subarachnoid space around the optic nerve. Papilledema caused by a sudden increase in intracranial pressure develops within 24 to 48 hours. Visual acuity is not affected in papilledema, although the blind spot may be enlarged.

Q. 3

In the normal human right eye, the peripheral field of vision is usually least:

 A

On the left side (nasally)

 B

In the downward direction

 C

In the upward direction

 D

On the right side (temporally)

Q. 3

In the normal human right eye, the peripheral field of vision is usually least:

 A

On the left side (nasally)

 B

In the downward direction

 C

In the upward direction

 D

On the right side (temporally)

Ans. C

Explanation:

C i.e. In the upward direction 

As described by Traquair – “the normal visual field is island of vision surrounded by a sea of blindness.” For coloured objects the field is largest for blue Q > yellow > red > green. The outer aspect of visual field extends approximately.

Ans. C

Explanation:

Ans. is ‘c’ i.e., Goldman type III 

  • Projected stimuli in perimetry are usually white and of variable size and intensity.
  • There are five different sizes on Goldmann scale designated by Roman numeral Ito V.
  • The standard used in both manual and automated perimetry is Goldman III (0.05″ and area of 4mm2). o Failure to recognize target size III necessitates testing with stimulus V
