Cataract Types – The Complete List

Cataract types is an important topic in Ophthalmology. It is an examiner’s favourite when it comes to NEET-PG as every year 1-2 direct one-liners appear as MCQs in NEET-PG. It is also an important topic in medical school exams as cataract is often kept as a case presentation and cataract types are frequently asked in viva-voce.

This article will enlist all the facts and related to cataract types.

Usually two types of questions are asked on Cataract types :

  • Which cataract is seen in this disease ? eg Cataract seen in Myotonic dystrophy is – ANS : Inverted Christmas tree
  • This cataract is seen in which disease ? eg Oil droplet cataract is seen in – ANS : Galactosemia

Also, the usual questions on cataract types will test you on either the morphologic appearance or the location of cataract (Nuclear, cortical, PSC).

With that settled, let’s get on with the list!
