let’s get on with the list!

Atopic dermatitis	Shield cataract	Posterior subcapsular
Diabetes mellitus	Snowflake cataract Snowstorm cataract	Cortical mainly

Down’s syndrome	Blue dot cataract

Snow flake Cataract - True diabetic cataract

There are refractile intralenticular crystals, which are cholesterol deposits. They are referred to as Christmas tree decoration cataracts, and they are not associated with hypercholesterolemia. However, the term Christmas tree cataract is most commonly known to describe the characteristic cataract (polychromatic iridescent crystals) that develops in patients with myotonic dystrophy.
