Q. 1

Which of the following type of cataract is most commonly associated with ageing?

 A

Nuclear cataract

 B

Intumescent cataract

 C

Morgagnian cataract

 D

Posterior subcapsular cataract

Ans. A

Explanation:

Nuclear cataract is the most common and type and the one most commonly associated with ageing. It consist of a central diffuse opacification and coloration that involve the lens nucleus.
  • Intumescent cataract is a form of cortical cataract where the nucleus is white and the capsular bag is swollen because of fluid absorption. 
  • Morgagnian cataract is a hypermature cataract in which entire lens capsule is wrinkled and total liquefaction of the cortex allows the nucleus to move freely in the bag and sink inferiorly due to effects of gravity.

Q. 2

Steroid induced cataract is

 A

Posterior subcapsular cataract

 B

Anterior subcapsular cataract

 C

Nuclear cataract

 D

Cupulliform cataract

Q. 2

Steroid induced cataract is

 A

Posterior subcapsular cataract

 B

Anterior subcapsular cataract

 C

Nuclear cataract

 D

Cupulliform cataract

Ans. A

Explanation:

A i.e. Posterior subcapsular cataract 

Steroid induced lens opacities are posterior subcapsularQ. Whereas anterior polar cataract is caused by perforating cornea/ injuriesQ.

Q. 9

Most visually handicapping cataract is:

 A

Rosette cataract

 B

Nuclear cataract

 C

Posterior subcapsular cataract

 D

Cortical cataract

Q. 9

Most visually handicapping cataract is:

 A

Rosette cataract

 B

Nuclear cataract

 C

Posterior subcapsular cataract

 D

Cortical cataract

Ans. C

Explanation:

Ans: C i.e. Posterior subcapsular cataract

Reduced visual acuity (gradual, painless, progressive) & visual field loss are manifestations of all types of cataracts

Cataracts & their effects

  • Nuclear cataract manifest as colour shift (more obvious after surgery), second sight/ myopic shift, frequent change of glasses etc.
  • Loss of ability to see objects in bright sunlight, blinding by light of oncoming headlamps when driving at night or glare may be the symptom of posterior subcapsular cataract
  • Cortical cataract may manifest as frequent change of glasses, monocular diplopia/ polyopia, glare or coloured halos around light

Morphological types of senile cataract

  • Common morphological types of senile cataract are :-

i. Cortical senile cataract (soft cataract):-Opacities in cortex may be of two types :‑

  1. Cuneiform cataract :- Wedge shaped opacities (spokes) in the cortex
  2. Posterior subcapsular (CupulifOrm) cataract:- Saucer shaped opacity under the posterior capsule.

ii. Nuclear senile cataract (Hard cataract) :- Opacity in the nucleus

  • Most common type of senile cataract is cunieform cortical (70%) followed by nuclear (25%) and cupuliform
